EPS is more of a server and super high end power supply standard, as long as they are at least ATX12V V2.x/EPS12V you wont be able to tell the difference between them, its just very minor revisions usually and often times, like on the 650TX and 750TX the exact version of the revision isnt marked down simply because revisions are small enough that even through 10 revisions its likely still fully compliant with the latest one.

Well, for a single GTX460 or dual GTX460 then 650TX is more than enough.
