PSU Question - Electrical - Amps - SLI

[foodfightr]

If I'm not running SLI, would I be better off with a NON-SLI power supply?

For example the OCZ PowerStream line:

OCZ520ADJSLI = +12V1@20A, +12V2@18A
OCZ520ADJ = +12V@33A

If I'm not planning on running SLI, will I take a hit running my video card on 20A, as opposed to 33A? Or if I'm not running SLI with the SLI power supply will I essentially have 38A (20A + 18A).

Well, the PSU may be SLI certified, but it will definately perform with no issue with a non SLI setup. You get less amps from a SLI one because it needs to split the signal, but no video card currently out there in the consumer market that will be used for gaming and such will use 20amps
