Which psu for SLI?

[Proclaim89]

Which PSU would be best for me to use with a i7 930@ 3.8ghz and GTX 680 LIGHTNING in SLI.

Corsair TX850

Corsair HX850

Corsair AX850
http://www.newegg.com/Product/Product.aspx?Item=N82E16817139015&Tpk=ax850

I'd assume ax850 would be best but the hx850 seems to trump. I know silver has the highest conductivity and i thought the HX series was silver but its not? I'm a bit confused lol, or would a tx850 bronze would be good enough for me?

thx

I would recommend the HX850. It has an 80+ Gold power efficiency rating and is fully modular. It also has ridiculously high ratings on Newegg.

TBH, all those PSUs are more than enough even for GTX 680s in SLI.
