PSU Whine

[sutty86]

right guys got a new bequiet psu 430 modular from scan,
and i think its the culprit to gpu load whine,
everytime i do a benchmark or play crysis it whines like crazy,
well im sure its the psu,
i bought the gpu from ebay 2nd hand
evga 260 216 cores SSC
is there anysort of test i can do

You can swap out the GPU and see if it still whines. You can swap out the PSU and see if it still whines.

And of course you can put the GPU or the PSU in another computer and see if they still whine then.

You can only be sure of a return if by putting the PSU in another computer it still whines, however the other options might help you come up with a strategy to fix the problem at your own expense.

As you dont seem to be 100% sure what it is thats whining, Id suggest rigging up a game, taking your side panel off and trying to pin point the sounds location.

a 430watt PSU is on the rather low side, so you might find that it's struggling a little - whats the rest of your system specs?


Also, I find the my GPU whines if I put it under load without turning the fans up a little, it soon stops after

Can you run on integrated GPU? That would eliminate the graphics card

If your using a 430w psu for a card that is (GeForce GTX 260 OC - 40A and a 550W PSU minimum) then you are stressing the components in the 430w PSU that why its whining......

I would return the PSU and get a certified 82% PSU like OCZ or something like that.....

You don't need 550W for an evga 260 216 cores SSC. A whole system load peaked at under 350W at hardware canucks with the following rest of spec:

Processor: Intel Core 2 Quad Extreme QX9770 @ 3.852Ghz
Memory: G.Skill 2x 2GB DDR2-1000 @ 1052Mhz DDR
Motherboard: ASUS P5E Deluxe X48
Disk Drive: Pioneer DVD Writer
Hard Drive: Hitachi Deskstar 320GB SATAII
Fans: 2X Yate Loon 120mm @ 1200RPM
Power Supply: Corsair HX1000W
Monitor: Samsung 305T 30” widescreen LCD
OS: Windows Vista Ultimate x64 SP1

So unless your setup is much more heavy on load then a good quality 430W supply is plenty. But emphasis on quality.

its not about Watts dude its about how much ampage is on the +12v rail to the GFX thats important if it is drawing too much ampage it will stress out the PSU which may make it whine....

That NV260 SSC requires 40A on the +12v rail and at least a 500w PSU

[c12038]

Extract from Guru3D website "GeForce GTX 260 A GeForce GTX 260 requires you to have a 550 Watt power supply unit at minimum if you use it in a high-end system. That power supply needs to have (in total accumulated) at least 40 Amps available on the 12 volts rails. "

Arcticle here http://www.guru3d.com/article/evga-g...ocked-review/4 look under Recommended power supply

If you stress out the +12v rail it could potentially damage the PSU or the GFX card as per indicated in the arcticle......

Hope this clarifies things

From that same link:

Our test system contains a Core 2 Duo E8400 3.00 GHz / 1333 FSB, the nForce 680i mainboard, a passive water-cooling solution on the CPU, DVD-rom and a WD Raptor drive. The results:

PC in Idle = 167 Watt
PC 100% usage (wattage gaming Peak) = 345 Watt

The monitoring device is reporting a maximum system wattage peak at roughly 345 Watts, and for a PC with this high-end card, this is not excessive at all.

A good quality PSU will be good on 12V rail amps, so again, you are fine with a 430W supply if it's good quality. The 550W recommendation is taking account of poor quality supplies that don't supply anything near their rated loads. I would avoid them outright, rather than trying to guess what load they are actually comfortable with.

It's really great that you're trying to help c12038, but it's not as simple as just taking the first thing you read and then applying it out of context. Like with your previous suggestion of running 2x hard drives causing slow frame rates, sometimes you need to think about what you've read and whether it's accurate for the situation you're helping with. But stick around Hexus and you'll soon become an expert - combined with your enthusiasm to help out and you'll become a very valued member I'm sure
