Hi
If I ever SLI a 660GTX would a Seasonic S12II-620W be enough?
Thanks

Yes, but if you don't already own it you might want to buy something with proper connectivity (for such a setup) in a first place, that is 4x PCIe connectors/

Well the 660GTX uses one 6 pin PCIe connector and this PSU has two so isn't that enough connectors for two cards?...

Indeed, I didn't properly read the OP (I was thinking about 660Ti SLI).

Yeah, the S12IIB 620 is plenty... what other options do you have available?

Well, the Litepower is trashy, the SS-650HT is superior to the S12II Bronze 620 (essentially an SS-600ET tarted up for retail), if you don't mind the spartan look of the OEM unit, and if it's similarly priced, the SS-650HT would make a better choice.

Could you link the shop/s from where you're buying? smile.gif

The SS-650HT is a much better buy, but you could save some money and go with a ~500W unit, already plenty for that setup (and there are a few good ones available, the S12II 520 is priced well).

I know the SS-650HT is superior in wattage and ampage but is it superior or inferior in quality? I mean how is the voltage regulation on the rails and how's the ripple?
Are there any other units (possibly from other companies) that are based on the SS-650HT?

Yes, the SS-650HT is a superior design, and it does perform better than the S12II 620 in all electrical parameters/metrics.... it's an indy regulated unit as opposed to a group regulated one for the S12II 620 (a pretty cheap solution really). Here's the retail version of the SS-650HT.
