Will the : Antec 900w

http://www.newegg.com/Product/Produc...82E16817371050

be enough to power x2 460 2wins ?

I currently have a Thermaltake 875w XT, did a psu calculator and it came out to roughly 896w recommended.

I was also thinking of getting one 460 2win and a 480 lightning

thanks for the help everyone!

For 2 460s, your current PSU is enough, quite possibliy for 3. Antec 900 would do all 3 EASY.

Do you mean just two GTX 460s? Or is there some new GTX 460 x2 version I don't know about (which I guess would be like four GTX 460s)?

The GTX 460 2Win does not support SLI, so that's your work cut out for you right there.

I forgot to mention one is strictly for F@H, I was thinking of getting two to have a minor improvement on my games and F@H on all four cores for when Im at work or just away from the PC.

2cables: itd be 4 460 cores, they dont utilize quad sli, which I admit was a bummer but I plan on 24/7 folding

The power draw of the GTX 460 2Win has been measured at 368W but I'm not sure if the review I saw accounted for efficiency, because the review is not clear about that.
Since you'd be folding, one can reasonably assume that you'd be roughly doubling that for a total of 736W. If you'll be using your CPU to help with the folding, I'd go with a 950-1000W unit personally, but the HCG-900 should be able to handle it.
Either way, rather than the Antec HCG-900, I might recommend the Corsair TX950. Also a good, proven unit, more wattage, less dollars out of your pocket.

Edit: a GTX 480 + GTX 460 2Win combination would consume less power but may not fold as fast.

Your current PSU is probably enough. But If you want that 900w, I think there are people on this site who wound't mind taking your current one of your hands

While I wouldnt mind a 1k watt psu, the problem becomes, space. This will all be done in a mATX Vulcan and currently the pump sits between the psu and 120 rad, I have an idea of where it can be re routed, which would then sit above the 120 rad and 5.25 bay, just gotta make the necessary measurements.

As GPU's become more and more power hungry, I would likely need to make another upgrade down the road, so 1k corsair or maybe the 1.2k Antec.

Another thing is I will be OCing the w3520 I have up to 4.2+ Ghz, I know it has potential of at least 4.5, but that will also suck up more juice.

Oh and I would assum the lightning 480 would take more power since its a 2-8pin and 1-6pin power requirement

opinions?

so which has a better rep with guys?

Corsair 1000w or the antec 1200w, both are similarly priced.
