PSU sufficient for GTX 260 SLI?

[Heligrin]

Im trully considering stepping up form my 9800GTX KOs to 2 260s, which would only cost me abotu 180 bucks, however, i dont know if my PSU is up to it.

My current system:
PCPC 750W silencer 60A line
E8400 @ 3.92 GHz 1.38idle/1.345Vload
eVGA 780i @ 436 FSB
2 evga 9800GTX KO @ 815/2270/1995
1 DVD/CD rom
2 HD
1x 200mm fan
5x 120mm fan

My system runs absolutley fine with all the OCs and fans etc. My question is how much more power will the 260s used compared to my 9800GTX KOs? I know the power usage is similar but i just dont know. Can you guys give me some feedback?

Thanks!

Should work fine. GTX 260 is not that power hungry.

A PSU being certified does not mean none certified PSU will not work. It just means those PSU have been tested and are known to work properly with those SLI configs. You can take a look at certified PSU and get specs to see what is needed to run SLI and compare to none certified PSU. It is a good starting point.
