Default Can my psu handle 285 sli?

Right now it's running my system with a GTX 295, 8800GTS and Q6600 overclocked fine. However i'm going to be selling my 295 for 2 285's, will it be enough to power it?

I think that he will not do the run. The voltage are easy much but the Amp are to low. And I never saw this brand before so I don't know if he is realy capable of pushing all the volt they say on a long time period

Ask for more

When I read the specs for that PSU it states 4 x 12v Rails each with 18 Amps......check what the Amperage requirements are for the 285,,,,,as well you will require 4 x 6 Pin PCI-e connectors. Provided the PSU has the right PCI-e Pins and the 285 requires less then 18 amps, you should be fine.

One would think that given the GTX295 is 2GPU's in one, and the 285's are single GPU solutions , so long as you have enough connectors, it will power it.
Mind you, I am far from being familiar with that PSU or its OEM so, I can't say I'd trust that running my rig.
If its powered yours so far, then you should be good.

This is what SkyMtl had to say about it a while back at the NCIX forums:
Quote:
Look at the ratings; this is the unit they use for the GameXstream 700W.

760W....pffft.
Is that GameXstream any good? OEM? Inflated wattage is not a good sign IMO...

Yeah sorry guys....didn't clearly read his Post......my answer I provided was for "single 285"...not 285 SLI.....spacing out....even had the amount of Connectors right..

Given that...I think I'd plan a new PSU for sure at some point in the near future. As noted above..Corsair..PC P&C to name a few.

What about HD4890 crossfire? And it was able to handle a GTX 295 and 8800gts. Shouldn't it be able to handle 285 sli and 4890 cf?

I agree if your looking at spending that much on video cards replace the PSU, you dont want to deal with the PSU failing and taking out the rest of your PC with it. Im also only seeing 2 PCI-E 6 pin connectors, I thought the GTX 285s took 1 6 pin and 1 8 pin? I do know that a single card takes 650w PSU so you can guess what SLI would require. You dont want to have to run those cards with the stupid molex to 6 pin converters, I never trust those things. Especially with a card thats worth over $300.

Corsair TX750W 750W ATX 12V 60A 24PIN ATX Power Supply Active PFC 140MM Fan - DirectCanada

PC Power & Cooling Silencer 750 750W ATX V2.2 EPS12 24PIN Active PFC Power Supply Blue - DirectCanada

those should both handle a GTX 285 sli setup, but not if you plan on running the 8800GTS as well, you may want to look at an 850w for that kind of setup. a Q6600 alone draws alot of power, the GTX 285s draw alot as well. Your PSU MIGHT run that setup for a while but its seriously just a matter of time before it fails.
