500W Power Supply kicks out sometimes - too much load?

Hi guys,
I have a brand new 500W power supply from Aspire:
http://www.performance-pcs.com/catalog/product_info.php?products_id=956
I have a problem though. When I turn the PC on, I can be working fine for a while and all of a sudden BAM, the power goes off on the system. I cannot get it to power back up unless I remove the power cable from the back and turn the power switch off and on. However, it seems to be random in how long it stays up.
I did a complete case rebuild, in which I added a lot more fans and a HardCano 12 controller and other goodies, which is why I went for something more that the stock 350W that came with my X-Dreamer II case.
Is this a problem created by how much load I'm placing on the PS? If so, I can remove a device or two, or make sure I don't pump the fan RPM up too much.

Hi Sharp,
The 4 Vantec UV-LED fans are rated for 0.25A each.
Here is the product page for the HardCano12 unit:
http://www.thermaltake.com/accessories/hardcano/a1845.htm
I'm fairly sure that it's not my overclocking as I was able to sustain those speeds even before doing the case upgrade and modding on a (generic) Turbolink 350W power supply.
The HardCano seems to draw on the 12V rail. What other components typically draw on this? I'll see if I can calculate it out and see if I'm just trying to draw too much juice.
Sorry for being such a n00b when it comes to this stuff. I don't know a lot about electronic engineering. I guess I should have paid more attention in university physics. LOL

Too much load on servers possible cause of JBO-26000?

Hi,
I'm currently trying to find out what the problem is with our Portal pages (yes, pages with an 's'.. meaning all of 'em). When trying to access the pages, it either returns 'OA Portal Framework Timeout' and, most recently, a 'JBO-26000' generic exception in one of the portlets. (and to add to the problem, none of the other portlets return anything.. not even an error message)
Since JBOs are messages generated by Oracle ADF Business Components, I was wondering if any of the JDevelopers can confirm the idea that too much load on the servers might actually cause the JBO exception.
Thanks a bunch!
Regards,
_lilim

I'm not quite sure about this, but one possible thing that high load causes is a lot of application module recycling. There are all sorts of ways this can cause problems, e.g.:
- VOs without key attributes that are set to passivate
- VOs that aren't set to passivate transient attributes combined with an app that expects the values to be there after AM recycling
-storing important information in fields (as opposed to BC attributes), which don't get passivated

My Power supply Pooped out

My G4 MDD 1.25 Power supply died, "dead as a duck", I shopped about new apple PS is more than the cost of the computer, plus they are not a stock item anyway (in my area).
Question,my PC supplier asked me why can't I use a PS from a later windows box, he says the connector to the mother board appears to have the same ammount of cables and colours, so, he thinks that the voltages may be the same just a matter of a few mins soldering the connectors across.
Has anyone tried this and with what particular windows PS.
TomK

Hi Nadav,
Thanks for the advice, No it blows zippo, easy way to tell it's dead is when power plug is inserted no small zappy noise is heard, Local Mac spare parts guy said these are hard to find now and mother boards are also failing.
I even put another fuse inside the PS, it blew that too..it's goosed.
Worst part is that it also took out the System HDD, and to make things even more worse it had all my latest emails were on that, system back up was only to two months ago..
Have decided to completely dump the G4 and Try to remain working on my Macpro for now, (Now No back-up Mac).
Another frustrating thing is that I had new clean power lines installed from the fuse box to the computers with surge protection adapters just late last year at a cost of over $1200.
Looks like sys back ups have to be scheduled every day or even more, I'm thinking that apple knew these total failures would occur and that could be why they introduced time machine..cynical viewpoint I know.
Now I have to also shelve my sonnet card and my AJA KonaLS card, what a costly waste of resources.
Cheers for the reply

Intel Xserve Blower for Power Supply 1 Out drops to 0 RPM momentarily

10.5.6 Server. Machine is less than a year old. Yesterday I configured Server Monitor for the first time and have received two notifications of the blower for the Power Supply Out changing to zero RPM. It is momentary and goes back to normal.
Everything else is in the normal range -- temp, voltage.
Is this normal or indication of future failure?

Hi Forum folks.
I've had a 6-month (ish) Xserve doing the same thing. Every day, at least once a day, I'd get an email / SMS, saying the power supply or blower was having a momentary problem.
After shutting down the server, I pulled out the Power Supply Units, and checked them out.
Turns out, one of them had a slightly damaged heat sink (damage visible without opening the PSU). So, I swapped it for a spare I'd purchased. And then got the damaged unit (damaged internally at factory by the look of it) replaced by my Apple Reseller.
Note: the newer Intel XServes (early 2008) have a 750w PSU, compared to a 650w PSU, in the 2006 Intel XServes. The older PSUs fit in the newer Xserves, but they DO NOT function. (You'll get an error in Server monitor).
Hope that helps,
Cheers,
Derek

PowerPC 7500 Power Supply Pin Outs?

Anyone got a link to page with the pin outs for a 7500 power supply?
I have a 614-0039 and I need to test it.... not sure if the paper clip trick will work to start it.
It's a 22-pin connector and no green wire!
Thanks

Anyone know how to test this power supply? It will not turn on.
I have 5vdc on only one pin. I have no computer to test it in.

Broadband drops out way too much!

I would like to know how BT justify their price hikes. I am now paying nearly £50 a month (basic) for phone and broadband, they can't even give a decent service! I AM SICK of my internet dropping out about 15 times a day! I had nothing but trouble with BT when I first signed up and it hasn't got any better. Why am I paying for unlimited broadband if they can't supply it? I have two laptops and an xbox. The xbox is wired, whereas the laptops are both wireless. But as soon as a combination of them are on, the connection is rubbish and speed is terrible. Sometimes it even drops when just one device is connected to the internet! I'm tired of seeing the "BT Hub not working" site and I am definately tired of my xbox live gaming experience being ruined by constant lagging and even being booted from games due to the drop outs! BT need to sort out their service because VERY SOON they will be told where to go..... Without getting a penny!

£50.00 a month for phone and broadband, someone is stitching you up or you make a lot of chargeable calls.
Previous bills for Unlimited calls, and BT Infinity Option 2 Unlimited:
29.49
29.87
26.15
28.65
29.00
add to these the monthly equivalent of the Line saver rental £10 a month
As for your wireless connection, a lot can be down to the type of house construction you have.
I see from your post that this is the 1st post you have made. Why not post ypour hub stats on here so members can see if there is a problem that might be easily sorted.
Also do a BT speedtest ( wired if possible ).
You say you are using some wireless eqipment, are they all Wireless N capable, or are some b/g.
you can try a download of inssider2 for PC or istumbler for MAC users and then run it. This will then show you the broadcasting networks close to yours and their channels including your own. You can then enter your Routers admin pages and change your wireless channel to a free or less congested channel.
Google search inssider2 or istumbler
Please post back, there are many members who are willing to give some advice to try and sort your problems out.

The Power Supply Fan is still working, but does not appear to respond to increased loads, and its speed cannot be increased using SMCFanControl. Any suggestions?

Hi all - My mac pro 1,1 has an enigmatic problem. It's quad-core, 3Ghz, running OS X 10.7.5. The problem began some months back, when running HD video conferences, HD streaming videos and some other graphics-moderate (I won't say intense) uses, such as slide shows in Just Looking. My machine has an ATY, RadeonX1900 card and 2 monitors - both Apple displays, one being 30 inch 2560x1600, the other being 24 inch 1920x1200.
When I start those types of graphics-moderate apps, after about 5 minutes, something would crash (the monitors making a noise as it did) and the displays would both go black. The power did not appear to be fully cut off from the monitors. I think that the underlying applications, however, did not crash. So, I could still hear and speak to people during video conferences, and I could hear the sound tracks of videos.
Attempts to restart the computer and get the monitors back did not immediately work to undo the problem, if done straight away. The only way to correct the problem (so as to have the monitors work) was to wait for a few minutes and then restart.
After a lot of puzzled looking at console logs (and I confess that I am not an expert), I ran into a blank.
But, because of the timing of the crashes (after ~5minutes use) and restarts (after some minutes wait), I reasoned that the problem might be temperature related.
Once on that path of thought, I found this article:
http://worldtv.com/blog/guides_tutorials/fixing_an_overheating_mac_pro_no_expens e_required.php
I installed both Temperature Monitor and SMCFanControl. And I experimented, and got interesting results:
Now to the puzzling bit: SMCFanControl shows that the speed of the Power Supply Fan doesn't vary much, even if I use SMCFanControl to ramp fan speeds right up. All of the other fans react to SMCFanControl, going up to and above 2500rpm when commanded. But the Power Supply Fan does not. Having watched it for a few days now, the Power Supply Fan, according to AFCFanControl, never varies outside of a range from about 600-640 rpm, regardless of what I do with AFCFanControl.
Also (and not surprisingly), whenever the graphics-moderate apps run, when I ramp all the fan speeds up using SMCFanControl, Temperature Monitor shows that the all of the temperatures within the machine plummet, except in the power supply locations. Power Supply Location 2 is the worst affected. Because the Power Supply Fan does not react as the other fans do, the "crashes" still occur.
I could post some screen shots of the read outs of SMCFanControl and Temperature Monitor, although I think I have covered the key points in this post.
It seems that the Power Supply Fan is still working, but does not respond to increased loads.
Instinctively, I'm worried that if that's right, it might be a hard problem to fix. Any suggestions? Help! I would really appreciate them!
Cheers
P

Thanks for your response Grant. I had already read about, and I think excluded, dust in graphics card/fan/assembly as a cause. The entire inside of the computer, including the graphics card/fan/assembly, is as clean as a whistle. It looks clean. I've cleaned the dust out every now and then (including a few days ago). Also, my undersanding (derived from the article, linked in my first post) is that I might expect to see high temperatures in the Northbridge and memory module B if the graphics card was overheating. According to Temperature Monitor, however, locations do not increase in temperature when I run the relevant apps. Finally, the graphics card/assembly does not feel too hot to touch.
It is strange that SMCFanControl lists the Power Supply Fan as being software controllable, if that fan is not. Still, your comments are consistent with my observations, as the fan simply does not respond to software control.
There are two upsides: First, I've something of a work-around. I've worked out what temperature must be achieved in Power Supply Location 2 for a crash to occur, and I can watch that location in Temperature Monitor, terminating the process before that treshold is reached. Of course, that's not ideal. Second, ramping all the other fans up does significantly delay the onset of the problem, and makes recovery time much quicker.
Is there any donwside to peridically ramping up the other fans when running the relevant apps? Given that it causes all of the other locations to cool significantly, could this lessesn the life expecancy of the mahcine? (I don't want to run the fans up all the time - that's like sitting next to a jet ready for take off!)
Also, a correction to my first post: Yesterday, with all the other fans running on full and running an HD streaming video, the Power Supply Fan did, eventually, slowly, come up to ~740rpm, which is much higher than the ~640rpm maximum I had previously seen, and this may have aided delaying the onset of the problem.
I'm not sure where this leaves me? The problem might now be able managed. Well, sort-of. But it's not eliminated.

Help! I need to upgrade my Dell Optiplex GX260 (tower) power supply!

Hi,
I plan on taking a trip to Best Buy today to purchase a video card and power supply for my Dell Optiplex GX260 (tower). I am looking to get at least a 500W power supply. Can you tell me the BEST power supply that will work/fit that Best Buy sells? Thanks very much.

I see that you posted back in March of 2009 so I hope that you haven't already fried a motherboard or PSU while learning the hardway, as I feel that I almost did. We have a Dell GX260 that my daughter wants to play some games on but I found out that the Graphic Card (ATI Radeon 7500 series) was not good enough for the games that she wants to play so I decided to upgrade the graphic card, unfortunately I found out that a lot of newer cards have PCI-Express connectors and not the PCI I need. As well, I found out that most of the PCI cards above what I have need more than the 250Watt power supply that I have. So I thought, why not just upgrade my my PSU and then I found out that Dell actually rewires their PSU differently than the industry standard ATX connectors but I see a lot of post and recommendations from people that say that you can use any store bought PSU to upgrade your Optiplex GX260 but BEWARE that if you bought your system after late 1998 then you have a Dell system that has their own proprietary wiring configuaration and even though you can buy a standard ATX PSU at bestbuy and it will seem to fit properly, it will either fry your new PSU or worse yet, it will fry your motherboard as well. In fact, I went to bestbuy three days ago and bought a graphic card and the salesman told me that if my PSU was not at least 300Watt, which is what the card required, that I can come back and buy a standard PSU from them and that would fix the problem. The salesman even knew that I had a Dell System so I wonder if BestBuy would be willing to replace my motherboard if I had fried it based on what the bestbuy salesman told me to do???? Anyway, read this link http://www.informit.com/articles/article.aspx?p=339053 and see what you think!! I am glad I stumbled across the information and plan on upgrading my PSU with a compatible Dell PSU or look for a Dell Converter (if there is such a cable) or just replace both my PSU and Motherboard as directed. I also think I might actually build my next PC from scratch with all industry standard parts, as I was very ignorant up until now that Dell was doing this to their products and I have 3 of their systems in my house....but no more!!! I did find a Dell compatible PSU 500 Watt on PCPower.com but it comes with SATA drive connectors and my Optiplex GX260 has IDE connectors so I don't know if I can get a SATA to IDE conversion or not but as you can see I am still researching my options. I might actually find it will be cheaper to just buy a new system or build the one of my dreams!!
I know I wrote a lot but I hope that this information is helpful to someone else out there who is in the same boat as me.

P6N SLI / power supply question

I have a question to pose to the experts. I am building a computer for a friend. He brought me the parts to work on. The motherboard is the MSI P6N SLI and the power supply he brought me is a KWi KingWin Model AP-450 with the following specs:
+3.3V - 22A
+5V - 35A
+12V - 15A
-12V - .8A
-5V - .5A
+5VSB - 3A
Total - 450W
The system will contain 2 hard drives, one Seagate Barracuda 7200rpm 80GB SATA the other a Seagate Barracuda 7200rpm 40GB IDE.
It will also have a SATA DVD burner and a XFX GeForce 8600 video card which does not have a power input.
CPU is an Intel 925 dual core chip.
In your opinion, will the 450W power supply be good enough to keep this system stable?

Total watts is pretty useless these days. It is more important that each rail has current reserve beyond what is attached to that rail. A poster in another thread had a 1000W power supply with 4 rails that he spent nearly $300 on. Each individual rail was spec-ed lower than the minimum for the motherboard almost all the excess power was on the drive connectors not the motherboard connectors and the 4 +12V rails were not helping the motherboard since only 1 rail was supplying the +12V to the motherboard. So in this instance a 500W supply that only has 1 rail that is 25A on the +12V is more powerful than the 1000W supply. In this case, the 500W power supply would be fine for powering up the motherboard alone, that particular 1000W supply would not.
Lesson here:
You can't just throw Watts at your system without determining where those Watts are going.
It only takes 1 leg of your power supply to be too weak, for the existing setup, to make things act weird. Doesn't matter how much reserve power you have on the other legs. 1A too weak and any chip can power down in the middle of things doesn't matter if you have a 2000W supply that cost $1000.
The components in your computer do not care about how cool your power supply looks. They don't care if it has LED fans or UV connectors or braided sleeves. It doesn't matter how much it costs. Once you find a list of power supplies that will work for your system, then look for adequate cooling, enough of the right connectors, etc. The 2nd to the last in the decision process should be glossy paint and lastly the price. Of course you may want to purchase that clear case power supply with 3 color LED 120mm fan. It may just be a conversation piece sitting on the shelf if it won't work in your system.
Good examples:
The first one may in-fact be the best one for a particular motherboard. The last one may not even power up a basic quad core system business workstation. You must research what you are buying. Don't just look at how cool it is.
This one has 25A on the single +12V rail. 550W
http://www.newegg.com/Product/Product.aspx?Item=N82E16817170011
This one has 16A on the +12V1 and 18A on the +12V2 rails. 500W
http://www.newegg.com/Product/Product.aspx?Item=N82E16817148003
This one has 7 +12V rails, several of them at only 20A. 2000W has 2 power cords and I want to know what case it fits in. I see feet on it and they are calling it a modular supply. There are other ways of doing things. Not everything has to be forced into one system.

Power supply problems

I'm currently running a 300W non-branded crappy power supply, the voltages are shown below. The problem is, the fan has pretty much given up the ghost and is making an outrageously load noise, I tried replacing it, firstly with 2 different types of Antec 350W powersupplys, both of which had to be sent back, and cost me loads of money doing so, now I've tried a non-branded 500W powersupply, but all have had the same problem: - They appear to begin to power up the system, the fans start for a second, then they stop, as if the PSU doesn't have enough juice to run things. It runs the system when I unplug the external power on the graphics card, but it won't run the graphics card on its own.
I guess this suggests it is more likely a graphics card problem, but if any of you guys have any ideas I'd be greatful. I don't see why a higher Power PSU would power the system when a much lower one would.
The 500W power supply voltages are:
+5V - 40A
+12V - 17A
+3.3V - 28A

I'm not sure what a D-bracket is mate. I've sent an e-mail to ATI to see if they know of any issues with certain power supplys, in the mean time I solved the problem by taking the fan out of the 500W power supply and putting it in my old 300W one not an ideal solution to the problem but at least I don't have to put up with that horrible grinding noise anymore!
Cheers for the help mate.

New battery/power supply problems

i bought my ibook on ebay, put in some upgrades and am pretty happy with it. One thing keeps making me extrememly angry. Randomly, without warning, the power supply cuts out. When I look at the port, the light's still on. This wouldn't be so bad because usually the battery would kick in. However, mine came without a battery. So, everytime my power supply cuts, the computer shuts off. What's the problem?

Mike,Check your Energy Saver options (Apple Menu > System Preferences > Energy Saver > Options Tab > 'Schedule' make sure this isn't set to turn off your iBook.
I'd also try resetting the Power Management Unit. (Click this link and follow the instructions).
At least your clamshell's a good deal lighter! (Doesn't it tip back too easily without the weight under the front?).
The problem with running a machine like this is that the Clamshell has no internal battery (unlike every other Mac ever!) this means that you really do need the main battery for correct operation of the system. You'll be forever re-setting date/time etc so it may be worth inv a main battery - even if it's a really cheap one that only gives you 10 minutes run time - it will guard against this type of problem.

600 watt power supply questions and video card upgrade questions

I am looking to upgrade to a Xfx Radeon 7970 Double D graphics card but i was wondering if the HP 600w psu that came with my Hp Envy Phoenix H9-1350 has a 8 pin and 6 pin Pci-e connector because that is what the Radeon 7970 needs. Also I am wondering if it will fit into the Hp Envy Phoenix H9-1350 because the case seems small but the card is only 9.3" long. I currently have an Amd Radeon 7670 but I think it is time for an upgrade but I am just not sure if the power supply has the correct power connections needed for the Radeon 7970.
This is the card I am looking to get:

This is the computer I have:
http://www.bestbuy.com/site/HP+-+ENVY+Phoenix+Desktop+-+12GB+Memory+-+2TB+Hard+Drive/6890832.p?id=12...

I understand you want to know if the power supply will have the necessary connectors for the desired video card.
According to the specifications, it lists the case as a mini-tower which is on the small side. You may need to use a tape measure to find out exactly how much room the system has in regards to length. It has become much better, but other components (such as the HDD) were at the end of the PCIe slot limiting the length of a video card. Sorry I couldn't provide anything more specific. The manuals are somewhat vague as far as the internal dimensions and I don't have access to one to verify the dimensions.
Ordinarily, I can find more information regarding the power supply not that seems not to be the case here. According to this thread, the PSU has two 6 pin PCIe connectors. You would need something like this to convert one of the 6pin connectors to 8pin. As long as the PSU is capable of pushing enough watts, it shouldn't be an issue. The card needs up to a 500W power supply, so the 600W power supply should be just enough to cover it.

Theater 550 Pro's PowerCinema 4 take too much CPU resource?

Hello all Theater 550 Pro users,
I am experiencing Power Cinema 4 is taking too much CPU utilization on my PC, versus any other TV viewer apps like WinAmp TV, FlyTV, etc. CLCapSvc.exe is the process that blatantly taking most juice out of the CPU, causing TV viewing experience on Power Cinema 4 bad. Anyone know how to fix this? Any known patch for Powercinema4?
Now I'm using WinAmp's TV plugin until I find a better TV Viewer prog. Any suggestion?
Do you guys use any other TV Viewer app?

Thanks Stu. I'm still figuring how to get mediaportal working on my PC as over here only have analog TV, no EPG, no scheduler, no nothing... just plain old TV Viewer is all I want. However, PowerCinema4's CLCapSvc.exe issue shouldn't be ignored too...

Help!!! in need of advice power supply is dead

Hey everyone i need some advice, i live in the uk and i have a 2 year old mac book pro and the power supply cable has heated so much that it has melted and stop working, what should i do?? should i just buy a new one or complain to apple and try to and get a replacement ??

This has happened to me before.
Just take the power supply and your laptop to your apple store (make an appointment at the genius bar) and they'll swap it out free of charge as long as ur still under warranty (or apple care)

Power supply question or Firewire issue

Hi
I have a workhorse Dual g4 with three internal video drives, three self powered Firewire drives and an internal Gina audio card. Recently I added a USB2 internal card and swapped my Viewsonic LCD for an Apple where the power is coming off the video cable. For the last 2 days my Firewire drives got balky. They mount but when I try to open them I get the interminable spinning beach ball. So far I am able to connect the FW drives to my G4 laptop and they seem to mount ok.
Am I asking too much from the power supply or is this a fair load?
Could the Firewire have failed.
Last week I had a high whine and lockup (heat related?) It's been funny ever since.
Is there an app that gives the status of the hardware?
Sorry lots of questions
Thanks
Enio

The XServe power supplies (like most modern systems) are rated for 100-240V, so will accept any input voltage in that range.

500W Power Supply kicks out sometimes - too much load?
