There is no program for such a use. You could technically use a PSU calcualting website but those are highly inaccurate and I don't recommend using one. That $16 Kill-a-watt is going to be your best bet, if you buy one make sure you ask us how to calculate how much your system is actually pulling as you have to calculate efficiency.

That isn't really a top of the line 650w unit with 540w on the combined 12V rails and I don't really think it would handle furmark stresstesting even at stock speeds. Though it would most likely run games perfectly fine. For SLI 570s a high quality 650w unit will be a minimum and 750w will give you (which I would recommend) is more than enough breathing room for overclocking.

I agree. Real tools are better. You can try one at home and see how much is it grabbing from your system now and calculate how much will be used if you add another video card.

Unless your running furmark and prime95 for 24 hours straight, your not going to hit full draw. It will be fine. take a look at picking up a new PSU in the next year.

So I think that an Antec EA650 could do the job with SLI GTX570 in everything but Furmark..

CHEERS..

Says the man with a Corsair-AX1200 and 2x 100 watt draw cards.

Not having a go at you champ, just pointing that out.

I ran 2x 5970s on a Corsair HX650 before i got the 850 version, and it got loud, but that's it. Worse thing OP is that it just turns itself off. Antec's don't have a rep for catching on fire when you hit 650 watt loud biggrin.gif

Simply put it is not recommended--especially if you plan to overclock.

By the time you feel like it you will have burnt out your current PSU and be out that and a new one. 2cents.gif

Yeah, thanks for the tips guys. I will probably not go on the SLI route until I can afford to get another PSU + GPU. I don't really want to run the risk of killing my whole computer.

Quick question that will make me pull the trigger = Will a PSU dieing on me kill all my components or just the PSU itself?
