This PSU with SLI?

It should do fine. That's a very capable unit. Your computer doesn't quite use as much power as many believe it does.
 
Better make that 1200w just in case, you never know. ;)

Amateur mistake, pray forgive. I'd fallen into the "believe the recommended spec" clusterf*ck. I must be losing my touch..
 
Dazzer, What hardware do you mean? Because I'm looking at getting a Q6600, EVGA 750i FTW and another GTS to run SLI...


Geoff, That calculator says I'd need 471watts, That's with a Q6600 at 3.4Ghz with a 1.45vCore.

If you added in all your fans, drives, lights, etc, then it should be fairly accurate. For $2 you can actually get the "pro" version which shows you the required amperage as well.

I believe most people overestimate what they need in terms of power, some people say you need at least 750W for an SLI setup, when in reality it only needs 450-500W. BTW did you set the processor/system to 100% load?

However, even if it only requires 471W, you don't want your 520W PSU to bebe under almost 100% load all the time, and it will fail much sooner.

+1

Exactly my point. I don't think 520W are enough to keep the whole system running almost fully. Your PSU might handle it but it could be pushing I guess.
 
IMO, go with a bigger Psu
A) So it powers the system with ease
B) If u ever wanted to add more hard drives or anything like that, You have enuff power there to do so :)
 
^^ True Might as well invest in a bigger one now so you dont have to later in life. That the way i saw it when I got my 600watt. In reality I only needed maybe a 300watt. The stock 250watt just wouldnt cut it for the card and extra hdd.

the thing is, how many 400W PSU's come with enough PCI-E connectors for say, dual 8800GTX's? they might have the amperage for it, but the connectors just arent there.
 
My PSU has two PCI-e connectors, so I'm guessing it'll be fine... Seing as people have ran 640MB GTS' in SLI and Q6600, I'm guessing it'll be good to go!
 
yours is a good exception to what i said, its a really quality PSU so it has what it needs to have, instead of just what sounds good.
 
I just found this on the net;

I'm using a HX520, and with a Q6600 at 3.51GHz, 8800GTS 512 clocked at 792/1890/2106 (I'd say throw in an extra 25W for a GTX), 3 HDs, and 4DIMMS. During Crysis I'm pulling about 280W-300W FROM THE wall. Factor in 80% efficiency and that's about 230-240W in the system. The CPU and GPU both fully loaded, about 270W DC. My 12V rail is rock solid, but with a single card setup it's very hard to stress the HX520. But I wouldn't be surprised if the HX520 could run a GTX in a SLI given the power draw I see in my system. I definitely have the headroom for an extra GTS, but sadly - my P35 doesn't support SLI.
