Another "is this PSU enough for" thread...GTX 57o SLI

post #1 of 9
Thread Starter 
I am on the brink of purchasing another GTX 570 to go with the one I currently have, but I am wondering if I actually need a new PSU or not. I was just looking at those too, but thought, I wonder how much power a system like that would draw and found this -

http://www.guru3d.com/article/geforce-gtx-570-sli-review/13

Since the max draw according to this article was under 600W, do you guys think it would be stupid to try 570 SLI on my current PSU, an Antec Truepower New 650 -

http://www.newegg.ca/Product/Product.aspx?Item=N82E16817371021

Think I would be OK with that, or should I just grab a 750W or something just to be sure? I'd rather spend the money on an SSD or something else if I won't need the PSU.

You'll be fine. I figure you'll be able to OC the cards safely to 850core if you wanted to with that power supply.

Anymore OC and your computer will probably just shut down during a game or benchmark.

Your unit can handle it fine.

Department or Redundancy Department decree:

Your 650W TPN is an excellent unit and more than enough for two 570s and a 2500K.

The thing is, I don't really want to sacrifice any OCing headroom. I want to at least be able to keep my 2500k at 5Ghz, as well as have both the 570's at my current 570's clocks of 900/1800/4000 @ 1.1V. After some more reading, I think I will be at the very limits of this True Power New 650.

Well, it sounds like I might actually be OK then. Thanks guys, looks like I can probably put that $100+ towards something else instead.
