890gxm-g65 strange bootup problem

After I change my OC profile and revert back to optimal/default settings sometimes it does not POST wherein only led1 is lighted and my graphics fan is extremely blowing at high speeds.
What I did is just to turned off the pc for about 5 to 10 minutes and now when I turned it on, everything works fine again.
Any idea what seems to be the problem?

Possibly your BIOS not auto setting to the correct memory SPD profile. Does it do it with one mem stick only as well?
Check the memory and SPD tabs in CPU-Z after you have reverted to optimal/default.
Maybe you want to post a screenshot of both.
I remember Henry posting some information regarding the quality or rather the lack thereof when it comes to Ripjaws.
Did you not have Apacer RAM before? You changed that? Was that when you got your new board?

MSI 890GXM-G65 Overclocking Problems

I have:
MSI 890GXM-G65 motherboard
4 GB OCZ PC3-16000 Platinum Edition memory (OCZ3P20004GK) runs at 1.95v and 2000 MHZ at 9-9-9-30
Sapphire 5870 1 GB video Card
AMD 955 Processor (Black Edition that runs at 3.2 GHZ)
Without anything else overclocked I cant even raise my front side bus to 204 without it not posting at 16 multiplier. 203 post fine. I upgraded Bios to 1.B.
I have several other questions, but this is the first concern I have and that I would I like to address. Hope my motherboard is not not "broken". This is mainly just a thread starter and will get into more overclocking questions/problems later one...after addressing this issue.

Here are my screenshots:
Im sorry but I made a mistake. Before I use the Control Center my Ram speed is around 1666 instead of 1706. I get 1706 after I up the Front Side Bus in Control Center to 256. Hope this didnt confuse any.
As far as the Hyper Transport speeds. I am getting as you can see in the mid 2500's. The Box and website show 2600. So is this a misprint because you would think that 2600 would be out of the box instead of an overclock?
My 12 volt rail is 70 amp. I am using the 850 watt Kingwin MK Power Power Supply.
And again another question that really hasnt been answered yet. If I can overclock on the software side of things (Control Center) should't I be able to overclock on the hardware side as in bios. For example I am getting 250 FSB on Bios, but I can only get up to 256 in Control Center. You would think that if it works in Control Center is should work in Bios. And this is a very Stable FSB too (after testing with 3dMark etc.)

890GXM-G65 PS/2 Keyboard

I recently bought the MSI 890GXM-G65 along with a 1055T. Currently my bios is v1.4 and my system is working fine. However, my board will not recognize my PS/2 keyboard. At first I thought it was a problem with my wireless keyboard but testing it with a wired keyboard results in a nonfunctional keyboard. Using my wireless keyboard with USB works fine but the board will not recognize input from the USB keyboard at bootup; that is, I cannot enter the BIOS. Booting with a PS/2 keyboard results in a nonfunctional keyboard even after Windows loads.
Any idea what might be the problem other than simply a bad motherboard? The PS/2 keyboards lights do flash once when the system boots.

Quote from: Fredrik on 06-August-10, 01:28:32
Silly little thing, but PS2 keyboards are only to be attached when there is no power in the system. While USB things really are to be attached when well into Windows.
Please enter Device Manager to have a look if there are half-way installed keyboards and mice, etc.
About your BIOS thing, something and probably the processor is likely not recognised. 1.6 update is for 6-core's.
About your Windows repair issue I can't quite say, but start with above and the rest might follow.
I guess I'm simply not understanding what I should do.
First you said that PS2 keyboards should be attached before powering on the system. I have been doing this but the motherboard still does not recognize it. Likewise, when Windows starts with only the PS2 keyboard, the keyboard is not functional and I cannot enter a password to login to Windows.
Then you said that USB peripherals should be attached when Windows has already booted. If I wait until Windows loads to my login screen and then connect my USB keyboard, it works perfectly and I am able to login. However, leaving it plugged in while booting results in the same thing.
If I connect the PS2 keyboard before powering on, wait until Windows loads, then connect the USB keyboard (to enter my password), and check device manager, I only see my USB keyboard (HID Keyboard Device).
As far as the BIOS goes, I just used Liveupdate to update to 1.6. However, I am still having the same problems.

890GXM-G65 will it boot?

just had a question for the people that own the 890GXM-G65 will it boot into bios with an unsupported cpu 1055t for bios flashing?
already ordered everything and dont want to have to spend money on another cpu even if it would only cost $40

This is a different issue ,you should open another thread.
Anyway you can t get 1000M if the switch in the router can t do 1000.
Is the router gigabit on the LAN ports?The router will limit you.

890GXM-G65 front panel - AC' 97 or HD audio?

Hello, folks. I bought an 890GXM-G65 and I am having a doubt regarding the installation. The audio connector from the front panel splits in two. One connector reads “AC’ 97” and the other “HD Audio”. My motherboard manual says nothing about which one should I use to plug into the JAUD1.
I have been researching and looks like AC’ 97 is from AMD boards and HD audio is from Intel boards. Is that correct? Should then I use the connector AC’ 97?
I appreciate any help!
Cheers,

890GXM-G65 - How to install SB850 drivers in Win7

I purchased the 890GXM-G65 mobo. I want to install the sata controller (southbridge chipset) drivers from AMD. I basically want to get maximum performance from my sata controller. I tried AMD drivers but had problems with installation. Also, do I need the drivers and application. Is better to use the default windows based AHCI driver or the AMD AHCI driver? Thanks
Windows7 Home Premium
2G byte Memory
AMD Phenom II X4 810
OCZ vertex (30Gbyte SSD)

I downloaded the AMD drivers: catalyst, ahci and SB. The SB drivers installation work halfway, and then they crash. I get a driver fail on installation. Not sure why. The sata controller device is correct AMD SATA Controller. I guess I need to see detailed instructions to make sure that I am doing this correct. Maybe safe mode. Any suggestions?! Thanks in advance.

890GXM-G65 a few issues...

Hey guys,
So here are the issues Im having with this board.
Im running a system that I have put together over the last 2 years, its kind of transitioned from platform to platform...
amd x2 550 BE unlocks fine to x4 @ 3.6ghz (8 hours prime stable..)
890GXM-G65
G.SKill Ripjaws 1600 CL7
Corsair HX850
MSI GTX465 GE unlocked to GTX 470
P180 mini (all fan ports filled)
Corsair H50 CPU cooled with push pull S-Flex fans
I have used the ram, GPU and PSU all before in a few builds and they check out fine, the system seems to run load stable using furmark, PCmark, OCCT and Prime95.
First off this board refuses to let me change 60% of my voltages from auto? is there a trick to allow you to set your own voltage? its locked at 1.325 right now which is what auto is setting it at. I can change DRAM, NB and SB voltages but that is all, and even then if I choose a some voltages that way it will default back to auto.. (example if I set DRAM to 1.6 it goes to auto but 1.7 will stick.) Obviously for overclocking this is far from ideal.. I know this system has lots of overhead left in it but I cant touch it without unlocking the voltages.
Next up I keep getting random BSODs, code 124, 20, 50, and 1... I ran memtest and it seemed fine, when I prime I usually run a couple 8 hour sessions of blend and it seems fine, and this ram was rock stable before. The BSOD only seems to happen for the most part when the system is idle, over the past 2 months ive had it BSOD on me while playing a game once only. This cant be temp related as I monitor temps and they are all well within safe specs, CPU never goes over 52c under load, motherboard never peaks over 45c, video card runs very cool and I have a pretty agressive fan profile set up for it. When I try and boot with the ram in 2/3 slots instead of 0/1 it refuses to boot no matter what I do. Ram is also being run underclocked (1450 CL9...) due to having to lower clocks on the CPU to try and stablize... Im honestly ready to drop this platform and go back to the i3 I was using before, was worlds more stable and much easier to hold at 4.2ghz.

And then I read the sticky about changing the voltages... DOH!, problem would be that im running the sidewinder x6 sans number pad to save on keyboard tray space or else I might have figured it out...
Will have to test a few things to determin if that will help fix my BSOD.

Which BIOS version latest V1.8/V1.B for 890GXM G65

Hi All,
I bought a new AMD1090T (6Core) with MSI 890GXM-G65 mobo along with 4GB RAM.
System is working ideally under Win 7 32-bit however in 64-bit it is not recognizing my Hard Disk which is being detected in BIOS.
System is also lagging after updating all the softwares.
Can you guide me??
Windows 7 Ultimate.

Quote
Yes, it does however it is giving me error that Hard disk is capable but the command failed
Quote
my one of the three hard disks stop getting detected in BIOS and hence then on Windows 7 64-bit.
Is it the same hard drive that did not appear in Windows before (the "command failed" hard drive)? In case the answer is yes, then this sounds like a bad hard drive rather than a board or BIOS problem.

there are 4 aps leds above the CPU. They are always lit no matter what. And bios defaults to disabling the APS feature. And per mobo manual, ther are only two phases, 1 led lit for power saving and 4 lit for full load.
Bios defaults are disabled for the APS, enabled for cool and quiet.
Will i see any difference if i enable it? Should i enable it? Or just leave it disabled.

HI,
maybe you are having this problem because the feature is not working in BIOS. After updating the BIOS on my 790fx-gd70 I also noticed that APS didn't work any longer. I contacted support but haven't heard from them yet.
You can however turn Phase Switching on after boot-up using "Green Power Center" in Windows.

890GXM-G65 Ram issues

Hey guys, I know there are a lot of ram posts here already and many more on the web but I have spent the last 3 days reading them and trying to follow their guides and nothing has worked for me so I want to see if there is anyone that can help me for my specific problem....
Ok I built a new system with the 890GXM-G65 mobo and an AMD Phenom II X6 1055T processor. I am also installing a pair of G.Skill F3-12800CL7D-4GBRM memory sticks (I know these are designed for the Intel's but read many people using them for the AMD after changing the timings and loving the performance), I pulled my old 1TB hard drive out my other system to use in this one which already has Windows XP Pro installed.
My problem is that the pc reboots after the windows loading screen. I have tried changing the timings in the "Advanced DRAM Configuation" in the CMOS (7-7-7-24, 7-8-7-24, 8-8-8-24, 9-9-9-24) and not had any improvements, I have tried using the OC Genie Lite to auto find the correct settings, I have changed DRAM voltages (1.5-1.65) and NB Voltage (1.3-1.35) I also have changed the FSB/DRAM Ratio from 1:3.33 to 1:4 to change from 1333 to 1600 with no change as well.
I am able to log into Windows safe mode, in fact at first I thought it was a driver issue and loaded all the drivers in safe mode already.
Another issue I see and dont understand is in the "Memory-Z" in the CMOS I never see any of the memory settings change even though I set them in the Advance config, is this supposed to change?
Any help would be much appreciated, I am pretty sure its a memory issue from what I have seen on the web, I bought the memory from newegg.com and have a short time left that I could probably swap them out for something different if that is what I have to do, but I would really like to make these work.
Thanks guys.

Download and install memtest86+ on a usb drive and boot from that. Do a 24hr memory test to tell you if the ram+cpu is good or not.
After that if you don't want to mess with your original drive, install XP on a spare drive and see if it's stable.
I'm using G.Skill Ripjaws with my 1055t and it's been stable so far.
Quote from: mattmatt77 on 03-June-10, 07:01:18
My other mainboard which my hard drive is from is a MSI 975X Platinum. A rep from G. Skill told me to test each memory individually and if I still have problems to replace the memory. Should I just swap them out or should I change brands? OCZ is the only company that is tested on the MSI site, should I just grab some of those?

890GXM-G65 keyboard issues

Before I go over specs, I am having the EXACT same problem described in this thread. The OP in that thread is correct in that the bios does NOT stop at the F1/F2 prompt after a CMOS clear -- it pauses for about 1 second then continues on its way. Subsequent reboots simply end up on a failed boot page.
My config: 890GXM-G65 main board with bios revision 1.8, AMD Phenom II X6 1090T cpu, 16G ram (posts), 675W power supply (Thermaltake).
All peripherals are disconnected from the system. I cannot get a PS/2 keyboard to work nor a USB keyboard in any port. I have run into this in the past on certain servers with legacy keyboard support and one could get around the problem by plugging in BOTH a usb and ps/2 keyboard but that is not working in this case.
A PS/2 keyboard will light all three (caps/num/scroll) on power on but keyboard does not work and once post is complete all three are off and non-toggleable. A USB keyboard lights up num-lock on power up or hot-plug and it stays lit. No input works from this keyboard either. I have no OS installed and no bootable media connected so I continually end up at the no boot media screen which says to press a key. On this screen I cannot press a key or ctl-alt-del with any results.
Since the original thread I referenced above was never "completed" with a fix I'm hoping we can document it here (and I can have a working system)

Well, that didn't take long to figure out, my next troubleshooting step got it.
Apparently to have the keyboard active during post (to get into bios) you have to have ONE bootable device connected to the system. I hooked up the DVD drive and the keyboard became functional. Disconnecting the DVD returns the keyboard to the previously non-functional state on reboots/power ups.

890GXM-G65 no S.M.A.R.T. support in bios.

Hi.
Few days ago i buy mobo 890GXM-G65, today wanted to check S.M.A.R.T. on one of my hdd, and i have a surprise, smartctl gives me that answer:
Quote
SMART support is: Disabled
SMART Disabled. Use option -s with argument 'on' to enable it.
Ok, i try with this: smartctl -a -s on /dev/sda and i receive that:
Quote
=== START OF ENABLE/DISABLE COMMANDS SECTION ===
Error SMART Enable failed: Input/output error
Smartctl: SMART Enable Failed.
A mandatory SMART command failed: exiting. To continue, add one or more '-T perm
issive' options.
Ok, so i reboot OS, check every option in bios and don't see nothing about S.M.A.R.T. bios version is 1.B (last). This mobo realy don't support S.M.A.R.T. features or this my "luck"?

Quote from: Svet on 20-July-11, 01:16:26
SMART don't really shows accurate info, often makes mistakes.
Maybe is not accurate in 100% (especially if we speak about Seagate drives, or windows soft like hd tune), but still is really helpful
Quote from: Svet on 20-July-11, 01:16:26
Also thing its available only in native IDE mode.[/color]
I think it doesn't matter (until today i never have problem on ahci or ide), but i check and still this same.

890GXM-G65 No onboard (realtek) analog sound

About a month ago I saved up enough of my precious dollars to upgrade my slow, single core computer into something a bit more passable for this day and age. The new computer is much better, but it is lacking something very important to me: sound.
I can't hear any audio. Windows, in all flavors, thinks the device is functional, while the Realtek control panel app swears up and down that I have not plugged anything into the back ports. I've talked to my dealer, friends, one online forum, and finally found my way here, a forum dedicated to MSI boards that I somehow didn't come across earlier or I would've come here straight away.
Well, without further ado, here are the specs:
890GXM-G65 MS-8642 BIOS 1.B0
AMD Athlon 2 X3 3.2Ghz
Crucial 2x2GB CT25664BA1339A
Antek25 650W +12V~38A, +5V~24A, +3.3V~24A
XP Pro SP3 x86 / Server 2003 R2 x64 / *cough* 7 x86
I have other hardware of course, but since I've been testing I've stripped it down to the bare essentials.
I also found a very similar thread (https://forum-en.msi.com/index.php?topic=151266.0). It was resolved by putting in a different sound card, but that's not an option for me.
As I've said, I've tried to figure this out with the help of others for some time now.
Things I've tried:
* Tried multiple OSes, including to my chagrin Windows 7. I was going to try Delphi but the installer didn't like my setup, and well, this IS a gaming rig so it's not worth figuring out why.
* Tried multiple drivers, both new, old, MSI, Realtek, and on 7 the default drivers, across all of the OSes above.
* Tried jumping the front panel connector. Supposedly you don't have to anymore, but just in case I shorted 5-6 and 9-10 to no effect.
* Tried every combination of settings I could think of in the realtek manager, especially the one related to ignoring the front panel jack detection.
* Tried removing, reluctantly, the board from the case.
* Tried fresh install of 7 on the stripped down and removed board.
* Tried RMAing the board after everyone concluded that the board was bad. This was very painful. I was without any reasonable computing power for a week. To my great shock, this did not help and I am right back where I was last month.
Things I can't try:
* Testing the front panel audio (I don't have any such connector; JAUD1 is open)
* Testing the digital out (again, no such equipment)
Things that people always ask just in case (if there's a stupidly easy thing I've missed though go ahead and ask it--I sometimes miss stupidly easy things):
* Is the on-board sound enabled in the BIOS? Yes it is.
* Do the speakers work? Yep. Worked since the 90s, works in laptop today.
* On 7 did you switch it from digital out to analog out? Yes, sort've. The analog out options couldn't be selected normally, but I could select the headphones option if I disabled the front panel jack detection. Not having a front panel, I was not surprised to find that this didn't work (though the green volume bar was moving). A 'disable rear jack detection' setting would be very nice.
I am stumped, as is everyone else I've asked--we all thought the old board must have been defective but getting a new, equally incapable board seems to put that theory to rest. I'm well past the point where I'd normally write it off and use a spare sound card, but this board only has one PCI slot, and it is occupied. The only available slot is the second PCI-E 16 slot, and I don't think they make sound cards for that. And even if they did I really don't have the money to buy anything new; I've already sunk more than I budgeted for on this.
Any ideas?

Enable Digital IO.. is not under properties.. Control Panel/Sound/Double Click (to open) on your choice of 'playback devices'.. in this case 'the default out choice..Speakers and then under the 'Custom' Tab.. it is the Only check box or option under the 'Custom' Tab. Odds are it is unchecked but worth looking. I unhooked my Speakers and it was still there. Also without my speakers attached is the Configure Icon box.. but it is unavailable to open, unless the output choice (the Default out choice) is clicked on and highlighted. Then you can enter Configure.
We are both using Windows 7.. The question of your posted pictures is seen in the pictures. Lower picture shows 2ea Default.. Green Circle active as default. Your upper picture doesn't show Speakers as a selection, it shows a Headset. So my question was leading to a possible conflict of Default outputs. No I'm not drunk, but I am electronic capable.. poss that's a reason my explanation is seeming drunk..lol
My point is.. when setting your DEFAULT output choice... If you have your speakers 1/8" plugged into the Boards 'Green" jack. Have it that way only... no other speakers or headsets attached. Make the Speaker out choice under Control Panel/ Sound and under the Playback tab.. the only Default choice. Undo any second Default selection. That is the Output choice showing a Green Circle with a check mark inside it. That is what you are assigning as the audio out you are using. Just to see if there is a conflict. Again the posted lower picture that you show under the Sound box has 2 defaults.
You also have the Realtek HD Audio Manager shown. Possibly that is a conflict.. Is one set different than the other? You have 2 separate audio control programs. One is the Windows OS Sound control choice, and the other is your Realtek HD Audio Mamager. If you un-install the Realtek HD Audio Manager program, you still have the Windows 7 OS Sound controls. Both is just an option. You do want to always have your Windows Sound programs installed.. it controls a lot to include your Theme Sounds and more... Your Realtek HD Audio Manager is optional. If both are not set for defaults out, such as the exact same output selections... they will conflict.
You can always reinstall the Realtek Audio program. Since you have no sound and don't know if it is a board electrical problem.. as in a broken circuit. Use just one.. Windows one!! Then if you have sound from the Green jack input on the board... it will tell you that the board is infact OK. Then it all boils down to which program to use.
Fixing a problem is a task of the process of elimination. Make it simple to see if it will work.
Try again removing the Realtek HD Audio, optional program. Plug your speaker into the proper output. Make sure that under Sound and the playback tab.. speakers are default. That green circle. Highlight the Speaker choice. Click on Configure. and follow to configure. Double click on the Speaker selection. Go through all the tabs and make proper choices. Also on your desktop, on the bottom right open settings from the Speaker Icon next to the Time and Date. Volume is on and up, and the mixer setting also are up for volume. Now you are setup for speakers without out a secondary conflict of two programs and 2 defaults. If you have no sound after that... at least you know you finally have all the proper settings, and no conflicts.
Keep it simple and basic until you figure out your no sound woes. Still not working? Then it's time do figure out if you problem is software based or hardware based. Man, I hope you are following this.. I really am trying to help. I know problems can be so frustrating. I build and fix a lot of problems for Friends. No master but I do understand diagnostic processes.
I hope the next Post from you is that your possible conflicts are gone, and you have sound. If it is a conflict? Sure seems possible.

MSI 890GXM-G65 Thuban Issues

Hi,
Sorry if I post this in the wrong section.
I've been using v1.0 original bios for MSI 890GXM-G65 board without any problems.
Recently I tried updating to v1.2 to enable support for X6 1055T as stated in the link below.
My cpu code is HDT55TFBK6DGR which is the 125W version and requires v1.2 bios.
http://www.msi.com/index.php?func=prodcpu2&prod_no=2012&maincat_no=1#menu
I am unable to turn off Cool'n'Quiet feature for the Thuban core.
Enabling or disabling the setting in BIOS has no effect at all.
Multipliers keep dropping to x4 from the stock x14.
I also could not find any setting in BIOS to switch off Turbo Core.
I posted the issues in detail here:
http://forums.hardwarezone.com.sg/showpost.php?p=45130922&postcount=66
I found out that the MSI 790FX-GD70 also do not have such a feature to disable Turbo Core.
In comparison, the Biostar TA890GXE has that setting in its BIOS so this is not a specific issue for 890G-based boards.
Lastly, I could not get CPU-Z (or any other programs for that matter) to display accurate readings of the cpu vcore (set in BIOS).
Will MSI be releasing a new BIOS soon to fix these issues ?
Thanks.

Quote from: Golden Arm on 18-April-10, 06:25:26
Ah, that explains it. How's that Thuban CPU running at stock levels compared to other Quad-cores (if you have had any)?
Actually that hardwarezone link in my first post goes to my mini review of the X6 1055T.
http://forums.hardwarezone.com.sg/showthread.php?t=2731901
Unfortunately I only have synthetic benchmarks to compare the results with.
This is my very FIRST phenom chip from AMD.
The only quad I ever tried was the Intel Q6600 (used for 1-mth) before sticking to 2-core processors ever since. LOL!

I don't see a bios update yet for the 790FX-GD70. This mb I am running is my brothers...haha. I am waiting for the 890FX-GD70.
One of our local overclocker "ridney" is using the X6 1055T on MSI 790FX-GD70 with the latest 1.11b1 bios.
He has the same cpu batch as me but he is on water. I'm not willing to go >1.52V on air for this hexacore chip (not yet anyway).
He had posted all his OC'ing @ http://www.xtremesystems.org/forums/showthread.php?t=249606
The screenshot posted (towards bottom of page) @ https://forum-en.msi.com/index.php?topic=136443.0 was his!!
The reason I posted my inquiry here is because I thought there would be newer (beta) bios for the 890GXM-G65 which MAY allow me to disable turbo core.

890GXM-G65 New Build

Hello
I am building a new machine but having blue screen crashes during OS installation. The machine spec is as follows:
Motherboard: MSI 890GXM-G65, with latest 1B BIOS. BOIS is set to default settings.
Memory: 2 x 4GB Corsair 1333 DDR3 Non-ECC (9-9-9-24) 1.50V, dual channel.
Power Supply: Arctic 700W.
Processor: AMD Phenom II X4 955 Black Edition Socket AM3 3.2 GHz.
HDD: Seagate 500GB 3.5" Barracuda SATA-III 6Gb/s
Optical Drive: LG BH10LS30 10x BD-RE with DVD±RW & LightScribe SATA Blu-Ray
First I tried loading my old Windows XP OS but this was was crashing at random points in the installation process. Sometimes I would get all the way through but it would crash during updating from the Windows Update website. I gave this up and decided to bit the bullet and put Windows 7 on it. This began blue screening almost immediately, but my most successful attempt has got to 66% in the expanding files phase of the install (several times it has stopped here). I had a 550W PSU installed at this time, so I decided to put the PSU shown above in, but this has made no difference. The blue screen message is almost always "IRQL_NOT_LESS_OR_EQUAL", which does not tell me to much. It might be indicating a CPU or Motheboard issue, but I cannot decide which.
I now have a pretty big investment in hardware and software, and not a lot to show for it. I would be most grateful for any pointers that anyone has to offer on how to proceed further with determining where the problem lies. Thanks very much for reading this.

The Corsair is for sure far more powerful then both others.
As you have to look at the 12V rail, it output 34A BUT that is continues power.
Those other PSU's will not do that, not even close.
You can simply not buy a powersupply that outputs 500W continues for a lower price then the Corsair.
But the entire game isn't about watts, it's about 12V amperes that can be delivered continues, the Corsair does that.
Those "brands" you name for sure won't deliver anything near and probably explode when you try.
Please do some reading at http://www.jonnyguru.com/ you will quickly find out that watts are not the game to be played, the amps that the 12V regulators can handle are.
BTW, he has some reviews about el-cheapo PSU's that blow to pieces big time not even reaching anything near the Wattage on the label.
Please don't fall for the Watt trap as it's abused by many cheap crap PSU's, even if they do look fancy.
Just read this test about the CX-430 and you know enough: http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story&reid=214
