I don't know anyone that assumes that the peak capability of a PSU (especially in network gear) is it's actual consumtion, but thats just me. I do agree I wish they'd publish at least approximate figures. It can be a deciding factor in a lot of environments today. Keep in mined 650W is high-line mode (~220/240VAC) - in 120V it's only going to be around 325W.
