Default HD 6770 on a 370w PSU

Hi forum,

I was gonna order this card. My machine's cpu only draws 65w not oc'd.
I have 3 hd I assume pull 10-15w a piece. 1 optical combo 30w? 4gb ram 1w per gb not oc'd.?.? So that's roughly 150w.

The TPD for the 6770 is 108w (source). So that's about 260 total...leaves me over 100w to play with.?.? Am I cool getting this card?

I don't much about PSUs but it says max 370@ +12 18a, +12 15a

It's a HP server psu that ran an AMD Opteron quad core.

Hmm, It's possible that it will work. It has the Amps. Though it's near the no go siz, so its not an easy answer.

Thats pretty low draw for the cpu, what model?

You should be just fine. :-) But you probably need to upgrade your PSU in the future tho. 370w is pretty low for all the modern cards now.
