Auxillary power supply for high-end graphics cards

Dear All,
I have an ATI Firepro card that needs 450W and of course the MacPro motherboard is not suited for the purpose. However there are a few auxillary power supplies advertised to supply extra power. Has anyone got any experience with using them?
Is it safe to expand the power range of your motherboard?
I'd really love to make use of this card (the FirePro V8750) as apparently it is the fastest for 3D graphics applications.
Regards
el

I remember someone in macrumors installing a power booster in the lower optical bay, in order to power dual 4870s. I was trying to look for the thread, but couldn't find it
I don't see a problem with using that to supply aux power, as long as it fits.
Another option: You probably shouldn't though just cause I don't know the long term effects (if any), but you can get aux power from the lower optical bay molex... I can't say I recommend it, just because half of the people say its fine to do, while the other half says not to.
I do know that people were using this option to run 4870s in crossfire; not sure how long it lasted though..
I'm assuming you want to use this card under bootcamp correct?

I have a HP Pavilion a6603w. I want to upgrade power supply to run powerful graphic card. Suggest

I have a HP pavilion a6603w desktop model number FK555AA-ABA a6603w. I have a low to mid level graphics card, which is the most that my power supply will handle.
I want to get a stronger power supply to run a high end graphics card with a self cooling fan. Can anyone suggest an excellent, reliable power supply brand and model that will fit into my desktop case with minimum fuss? I am not tech savy but I have replaced my video card and hard drives with no problem.
Thanks,

Hello lugnut1204, I checked the specifications for your system and is appears the system shipped with a 250 power supply. The dimensions for this power supply are 5 15/16 inches wide, 5.5 inches long, and 3 3/8 inches tall. Since your system is a MicroATX version, you would be slightly limited to a power supply of the same size as the original power supply.
Here is a link to Newegg where a Corsair 600 watt power supply can be found with almost the exact same physical size as you original 250 watt version. The Corsair power supply dimensions are 5.9 inches wide, 5.5 inches long, and 3.4 inches tall.
If you get a power supply too long, it may interfer with the back of the CD\DVD drives.
You would need to locate a video card that you wanted and make sure the power supply requirements were less than the 600 watt Corsair model. Most of the mid to higher end cards require at leaset a 400 to 500 watt or greater power supply.

Xserve and high end graphic cards?!

anybody tried to put a new graphic card (like ati 850xt or similar with 256 memory) into a xserve??
could it work? i want to use xserve as desktop machine with gb ram on photoshop... so i need as well a high end graphic card ...
any suggestions?

No, you can't do this. The Xserve will only take PCI video cards; high-end graphics cards all use the very high speed AGP interface. The best graphics card you can put in it is probably going to be an ATI Radeon 7000 or thereabouts.
The Xserve is not designed as a desktop machine. My suggestion is you buy a PowerMac G5 instead

Does a high end graphic card really make a difference ? or is the CPU more important ?

NVIDIA has the Quadro CX (very expensive)
http://www.nvidia.com/object/builtforadobepros.html
They mainly talk about h264 encoding.
Does it help as far as timeline editing ?
Im shooting in HDV but final project is SD MPEG2 for DVD
Or does a faster CPU work better. Multiple Cores.
Is it better to get a faster Quad Core Intel Core i7 Processor ?
Intel® Core i7-940 Processor (2.93GHz) (Quad-Core)
or a slower Processor speed but dual ?
WS DUAL XEON E5504 2.0GHz, 8MB cache, 800 MHz, 4.8 GT/s QPI (Quad-Core)
WS DUAL XEON E5520 2.26GHz, 8MB cache, 1066 MHz, 5.86 GT/s QPI (Quad-Core) [+$385 ]
What role is the graphics card really having.
I have read some places that as long as you have a good card you don't have to waste money on the top end ones.
Any thought would be helpful.
Thanks: Glenn

IMO a Quadro CX is a waste of money, unless your editing life consists of only encoding to H264 and even then it may be a waste of money.
You may be better off with more capable CPU's and a better disk setup.
Have a look at all three topics linked to here:
How to get the best from a PC? Some guides...
Do read them carefully, including the responses, since there is some info on the performance of dual Xeons versus i7 that may help you decide.

Multiple High End graphics cards

Does anyone know if the Mac Pro is able to use multiple Quadro FX 4500's or possibly a Quadro FX 4500 X2. And if this is not possible, would a Quadro FX 4500 in addition to one of the consumer cards work? I require at least 4 graphics outputs (2 to drive a walleye stereo wall, and 2 to use with desktop monitors) and would prefer to use the Quadros to the 7300's at least for the stereo wall and if possible I would like to get the same level of performance on the desktop monitors.
Thanks
macbook pro Mac OS X (10.4.6)

Based on careful reading of the recently released development notes
<http://developer.apple.com/documentation/Hardware/Conceptual/HWTechVideo/Articles/Video_implementation.html#//appleref/doc/uid/TP40003994> and
<http://developer.apple.com/documentation/Hardware/Conceptual/HWtechPCI/Articles/pci_implementation.html#//appleref/doc/uid/TP40003937>,
it may be possible to install two ATI Radeon X1900 XT cards, one in slot 1, and one in slot 2 (also covering slot 3). The PCI bus would be set to x8 x8 x1 x8.
The configuration would meet all the cooling and power restrictions. There are auxiliary power connectors for both slots 1 and 2.
This would give you four displays (all could be up to 30") with independent resolution and rotation.
It is not a standard configuration, so you would order the Mac Pro with one ATI Radeon X1900 XT and order the second as an add-on
<http://store.apple.com/1-800-MY-APPLE/WebObjects/AppleStore.woa/wo/6.RSLID?mco= 220D662A&nplm=MA631Z%2FA>. Note where it says:
"System Requirements:
Mac Pro with available double-wide PCI Express slot or two standard slots". They wouldn't say that if it was only allowed in slot 1 (the only double-wide slot).
There would still be one empty slot, x8, with 36 watts available.
You might also be able to use two Nvidia Quadro FX 4500 boards if you could find a second board. That would leave 80 watts for the last slot. I don't think you get display rotation with Nvidia boards.

Problems With 4K at 60fps & a High-End Graphics Card

I'm having major problems editing footage shot at 3840x2160 @ 59.94. The video will play back fine initially, but after a few seconds, the video starts chugging along until I get less than 1fps. I have the same problem using adaptive resolution during playback set to 1/8.
So, I would think that I might need to upgrade my hardware, but what is the bottleneck?
Premiere Pro 2014.2 & AME 2014.2
Windows 8.1
Intel Core i5-4670 CPU @ 3.4 GHz
16GB of RAM
NVIDIA GeForce GTX 780 Ti (that's 2880 CUDA cores!)
The footage was shot on a Panasonic HC-X1000 with MP4 selected as the output format.
I have a 1 minute test file from that camera on my SSD. It's 59.94fps and shot using AVC at about 155 Mbps.
Since Windows 8 doesn't come with any way to monitor the GPU usage, my sysadmin installed Geeks3d GPU Shark. It seems to work, as it was accurately able to detect GPU usage in external benchmarking tools. Maxed out at 99%.
I moved Premiere's cache folder to my SSD to see if that had any affect. Mercury Playback Engine is definitely ON.
When I try to playback the aforementioned 1 minute clip in Premiere, it:
very few dropped frames, maxes out at around 29% of GPU usage, CPU virtually 100%
plenty of dropped frames, GPU percentage starts decreasing, CPU virtually 100%
around 1fps, GPU virtually 0%, CPU virtually 100%
I didn't list the RAM, but it's nowhere near 100%, and goes up about a gig or so during playback, and it's not near the Memory ceiling of 10.9 GB that After Effects, PPro, AME, PS, and others share.
Why does the GPU stop working when the number of frames dropped significantly increases? And why is it only using less than 30% of my GPU during playback while editing?
With Mercury Playback Engine off, I noticed only a minor decrease in performace. The GPU was still used, but much less: maybe 10% or so.
Also, why on earth does my encode with Mercury Playback Engine GPU Acceleration (Cuda) switched on encode with 100% CPU and 0% GPU? I'm trying to encode H.264 at the Match Source - High bitrate preset. AME + Mercury Playback Engine = 0% GPU usage?! There are no effects applied. No panning, scaling, video effects, nor audio effects. Literally, drag clip into new timeline (that matches clip settings), and encode using AME. What the hell is going on here.
Can someone explain how the Mercury Playback engine is supposed to work, and why it doesn't seem to be leveraging my powerful GPU?
Any recommendations for alternate GPU profiling tools, perhaps?
I can ask my sysadmin to upgrade the CPU, but I'm not sure how much to go up.
Note: I also tried bringing the footage into a sequence at 29.97fps, but it didn't help very much. I was hoping that reducing the playback framerate would help.

There are no effects applied. No panning, scaling, video effects,
That's why no GPU during export. Encoding is a CPU only process. The things you're not using are some of the very things processed on the GPU. Add some and you may see different results.
I would expect playback to be better with your hardware. If you care to upload a clip for me to download, I can test it here.

Looking for a new graphics card.

Before I post my specs; I cannot get a new power supply for a while, I ONLY want to explore gfx card options, I already know my choices will be limited so I would like those few choices to be listed because I'm not entirely sure if I can find the right one to buy, help would be greatly appreciated.
http://h10025.www1.hp.com/ewfrf/wc/document?docname=c01616203&tmp_track_link=ot_faqs/top_issues/en_u...
Everything you need to know, I will continue to look around, any suggestions would be great.

As I pointed out on another thread, shopping for something that you don't plan on buying for a while isn't worth while because prices, and models change constantly in the computer parts field.
A good PSU brand : ThermalTake, Corsair, Antec, to name the first three on my mind
Graphics: PNY, ASUS, Zotac, EVGA
For your case, i'd shoot for a 400-550watt psu, and then hopefully by the time you have enough saved up, shoot for a GTX 430. Solid card, good performance, lower price.

Creative Cloud background service constantly uses high-performance graphics card on MacBook Pro

On my MacBook Pro mid-2010, I recently noticed that the high-performance graphics card for some reason was constantly on. In MacBooks as of 2009, there are two graphics cards that can be used, one integrated, one PCIe. The integrated one is less powerful, but is used to preserve battery. The other one is enabled when there is a high demand for graphics power.
I saw that when the Creative Cloud service (with this I mean the general software package that tracks for updates and syncs fonts and files) was loaded into the system, the MacBook automatically starts using this high-performance graphics card, even without any other software running, just freshly from boot. This, of course, drains battery and I don't think that much power is needed to run a background service. The only way to stop the high-performance graphics card from kicking in, is by terminating the complete Creative Cloud service, which is of course not very useful when you use the sync feature a lot.
Is there a solution for this problem, or can you release an update of the software that addressess this issue?
If I need to provide you with logs or other relevant information, please let me know.
Thanks in advance, it's kind of annoying as it is now.

Same here. Macbook Retina 15", purchased earlier this year.
Nice (and free) utility to monitor GPU-usage is:
gfxCardStatus from http://gfx.io/
Helped me to notice that it's better to quit Photoshop if not using it because it still uses the nVidia GPU if Photoshop is not even the active application (eg. running in the background).
But still, sometimes after closing Photoshop, gfxCardStatus says that nVidia GPU is in use for process 'Creative Cloud'.
I'm mostly running on battery and nVidia GPU consumes much, much more battery than the integrated, Intel HD Graphics 4000 so this is a big issue for me.

Portable Power Supply for iPhone 3G

Hi,
I am looking to buy a portable USB power supply for my iPhone 3G.
I will be flying next month, so I need something to provide additional power while I am in the air.
I have searched around, and found:
IGO® POWERXTENDER UNIVERSAL AA BATTERY-OPERATED CHARGER
http://www.thesource.ca/estore/product.aspx?language=en-CA&catalog=Online&catego ry=iGo-HO&product=2739104
IGO POWER TIP-A133 (adapter for iPod/iPhone)
http://www.thesource.ca/estore/Product.aspx?language=en-CA&catalog=Online&catego ry=iGo-Tips&product=2739128
I live in Canada (so I can't buy from places such as Amazon.com) and would like to keep the cost to a minimum (I don't fly all that often).
I am wondering what people recommend for an affordable portable power supply, that accepts USB?
Thanks for your time.

There is power lost when using these chargers. Loss due to current creating heat in the wiring, loss in the iPhone battery that is being charged due to resistance in the battery, and loss due to the semiconductor devices used to manage the charging process. Not all of your 1000 mAh "ends up" in the iPhone battery.
I said "more than half" and that is literally true but a little pessimistic sounding. Maybe 70-80 percent. But I do not know. It will not be 87 percent. That's still good, to me.
Here is a quote from the instruction sheet for my 1200 mAh Richardsolo battery:
"If you have a 20-30% charge remaining in your iPhone, a fully-charged backup battery will bring the iPhone back to about a full charge. Once your iPhone is below 20% remaining battery charge, you may
not quite get a complete recharge from the backup battery, but close."
I find those percentages to be about right.
Regarding Amazon review, I think that is true only for an iPhone that is only partly discharged, not completely discharged.

In a comparison it looks practically identical to the 125W G46-970a. Except the G46 has a sound optical out--the features list says the Gamer board doesn't--and the board pics confirm that. Board looks to have better software than the G46--possibly better sound output, maybe.

Is the power supply for iPhone 3G only 120v?

Is the power supply for iPhone 3G only 120V

This is all true.
The iphone 3G can only be updated to 4.2.1. It will not support any version higher than that.

Which power supply for k8n neo2 Platinum

I need to buy a new power supply for my computer. With the ATX12V v2.2 standard and ATX12V 2.01 and the "no -5v on new psu's" issue I'm at a loss as to what to look for. I have looked and cannot find what "standard" (is that even the correct term?) the k8n neo2 supports.
My main requirement is that the psu be 550-650 watts and have modular cables. I know someday I will have to upgrade my system to PCI-E and modern components, so I would like a PSU that would work now and in the future.
Could someone point me in the right direction?
Many thanks
system spec's
Motherboard- MSI K8N Neo2 Platinum
CPU- AMD Athlon 64 X2 Dual core 4800 939 socket
Memory-CORSAIR 2X1G Twinx2048
Video- ATI HIS 4670 1GB AGP
HD- Seagate 100 gb 7200 rpm
Drives CD-DVD and CD-RW
PSU- Ultra X Connect 500W ATX
Sound- Creative SB Audigy2 Gamer
OS- WinXP Home SP3 32 bit

Why do you need 550-650W or is that just because of future needs? I would suggest one of the Corsair +12V single rail modular PSU's if you insist on the modular design. Check newegg for what they have for modular in the Corsair lineup. I'm sure you're aware that their price is considerably higher than the non-modular. K8 MB's that needed -5V are the early ones that had Creative Sound Blaster onboard audio.
HX650
   * Was: $139.99
   * $109.99
   * After $10.00 Rebate
   * $10.18 Shipping
That's what it is now but if you don't need it in a big hurry you can probably wait a while and get for the same price but with free shipping.
Edit: Gee, Ultra with blown caps, I just happen to have a xPRO 800W that blew some caps, repaired it and started going bad again and then got my TX650 to replace it. Got it for $70 after rebate (which I haven't received yet) by waiting for the right price, rebate and free shipping. VX550 would have been good enough but at the time I got the TX650 at a lower price.

New Antec power supply for p7-1003w doesn't fit?!

I got a new power supply for my p7-1003w tower only to discover it would not fit. It was getting caught somehow so I looked and noticed it was not the supply itself but the black plastic bezel piece around the AC connection hole.
Has anyone else faced this? The original power supply doesn't have a bezel, but all the Antec supplys I see do.
If you've had this problem of the bezel beign too big what did you do bend your back plate? lol or is their a certian brand of supplys that don't have the big bezel around the connector hole.
Thanks!

Hi,
Can you better describe the issue? See the below image:
