I need some clarifiction

post #1 of 15
Thread Starter 
At the moment I have a Gigabyte 1200W psu with

2 x Zotac GTX 570
1 x Zotac GTX 275

The spec for the GTX 520 says it has a max of 225W power consumption

http://www.zotac.com/pdbrochures/vga...x-570_v1.1.pdf

And the GTX 275 has a max of 216W power consumption

http://www.zotac.com/pdbrochures/vga...X-275_v1.3.pdf

So that means I can remove the rather inefficient GTX275 and because its a double width card that covers my fourth PCIx16 slot, I free up two more slots for two of these new slim GTX 570 cards I've seen arrive on the market.

Will my power supply survive?

2x 570s w/ moderate overclocks + a cpu w/ overclock could run on a good 650w PSU, so im going to say no problem.

Thanks!

My only possible issue could be these single slot cards have no rear hot air path like the double width cards. My GPUs are running most of the time and the air expelling out the back it, HOT! enough for me to add an external 120mm covering the vents to also pull air.

So maybe a GTX 590 maybe better as it has two GPUs anyway.

A 1200w is overkill for any setup, even SLI, out there. You're more than okay.

I have no idea how good that Gigabyte 1200w unit really is, but if it can put out at LEAST 650-750w (which it honestly should), then you'll have no issue with any dual GPU setup you want. You could likely handle tri or quad SLI though with it.

I'd steer clear of the GTX590 though. Last I heard, they were blowing up left and right due to a bad power setup. If you REALLY want high end power, grab a pair of 580's.

Should work fine. The Odin Pro 1200w is a CWT PUC unit. Same platform as the TT Toughpower 1200w and Corsair HX1000.

Thanks, I think the 590 problem was due to over-volting though overclocking software like MSi Afterburner.

I already have a pair of Zotac GTX 570s, they are only a few months old and its much too soon to think about replacing them. But my old GTX 275 is looking a little but past it right now.

I'll think about it for a while and lets see, a Bday gift to myself next month maybe.

I'm pretty sure that he's saying he wants to run QUAD 570s, not SLI. As such it depends on the quality of the gigabyte PSU, I assume you're going to be folding 24/7 on all 4 570s? And possibly your CPU? This is actually going to be a bit of a strain on a PSU so I would suggest making sure yours is quality ( I have no idea what gigabytes are like )

1200W is still fine in that case, as long as it's actually putting that out.

That's why I said to make sure it's a quality unit. It needs to be rated to run 1200W continuously, have enough AMPs on the 12V rail and probably be rated at 50C (it sounds like the inside of his case is going to get very hot) to boot. Since I have no idea what that gigabyte is capable of, he should probably look at his side panel and make sure that is the case.
