GTS 250 SLI Power Supply

ocz psus are mediocre at best. get a corsair. maybe a 650

I contacted BFG tech support about this and they sent me this in response:

"As far as the power supply
goes, one GT250 requires a minimum of 475 watts and as a general rule in an SLI
setup you should assume 1 + 1/2 for both cards in SLI. That would put you at a
minimum requirement of roughly 712 watts, well outside of your 600 watt power
supply."

Any truth in this statement?

For a pair of GTS 250 in SLI, the 600W PSU is marginal. For a system with a single GTS 250 the recommended PSU is 450 Watts minimum.

Therefore, you may be better off with the 850 Watts PSU that you selected.

In my system, I have a GTX-275 as well as a GTS-250 (PhysX) and I am using a HX 850 (850 Watts) Corsair PSU.

They're out of thier minds.

"OCZ ModXStream Pro 600 W proved to be an outstanding mainstream 600 W power supply, surprising us at all and every level."

Hmm... it seems like I'm getting contradicting answers here. Is my power supply alright or do I need a new one? If I get a new one, how many watts do I need and what brand should I get?

You need a new one - 750 Watts or higher. http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Whether your PSU is enough or not depends on the rest of your hardware.

Use http://extreme.outervision.com/psucalculator.jsp and look if it suffices.

But all in all i think your ModXStream 600W is enough for your two GTS250.

Based on the calculator, it seems like I have enough power. And I have run OCCT power supply test for 2 hours without problem. I'm starting to think the BSOD isn't because of the power supply since I'm getting the BSOD even with just a single video card.

are both cards giving you the BSOD as you run them individually or just a specific single one?

I am currently testing my memory again with memtest. Afterwards, I will check the other video card by itself to see if it BSODs on me.

And although I might not need a new PSU, the 850w one has really good reviews from some sites:

And since it's on sale for another couple hours, should I just go ahead and grab this thing for 50 bucks?
