I have a GTX460 right now, but I plan on upgrading in the fall. One would assume a new video card would be more powerful, but does that mean it requires MORE power? Or does it depend on the model?
I thought you wanted to SLi with another GTX 460 ? I would recommend that, often much cheaper and better performance for the money.

Yes, it all depends on the model. A GTX 460 only draws 160W, and that is at 100% full load.
If you're choosing a GTX 580, it would be another story. But frankly, a decent 500W should be able to run that too.

I plan on upgrading to a single card, whatever is $200-250 when October rolls around. If I have to get a new power supply, so be it I guess. Wouldn't two GTX 460's draw more power than a single, better card anyway?

With 2500K and GTX460 You should be fine with Antec 500W. I would recommend You at least 550W, but 500W is more than enough for this configuration.

Even with two 7200rpm hard-drives?

Perhaps they will draw a bit more power, but hardly anything that matters. However, if you pick a 650W PSU, you don't need to worry about the power draw. My rig only draws up to 550W. Even with this overclock.

Another GTX 460 is probably going to be a lot cheaper, but that's your call.

You're good - chill. With a 2500K you'll never draw over 300W with a single GTX 460. You have a decent PSU, that's the important part.

At stock, a 2500K draws 95W. Your current C2D draws 125W, if I remember right.

Yes. On that config. You will be able to run R6950 GTX570. AFAIK Antec Earthwats is one of the best in his class. So You don't have to worry. I think You could be able to use GTX 460 in SLI with 550W PSU, but You'll have not much headroom to further upgrades. But yea... 500W is enough. 1 HDD draws about 10-20W of power.

Ah, good to know. Thanks a bunch. As for the video card, a second GTX460 would be cheaper, but I'd likely have to get a power supply and maybe a new case (can't imagine cramming another one of those beasts in my case, but maybe it'll fit).

I belive another 460 should fit. Might get tight, though.

Actually, your 500W should be able to handle 2x GTX 460's. But I wouldn't recommend it, due to it's lack of 6-pin Aux connectors.

You could use the molex connectors with your 500W PSU but I heard some people had their molex cables melted because of the high current that went through the molex cables.
So this is why I'm recommending x4 6-pin connectors. Unfortunately, no decent PSU below 600W seems to have 4 included. A 550W should have been fine.

Anyway - get another GTX 460, a more capable PSU, and good luck !

I feel like my case would turn into a sauna with two of those hefty GTX460's. It might just be cheaper to sell my GTX460 when I want to upgrade, and use the $100 or so I'd get towards a new single card
