Not alot to go on and there are a number of 80 PLUS Quad Rail PSU's that are crap that I wouldn't use but would have the power for a GTX460.
Can you open the case and read the psu label ?
Unfortunately not, as I'm talking about a system I don't have yet.
I'm just checking that what I'm buying is enough.
I could try and find out though, and reply back here.
