TOO MUCH POWER???

[david8115]

i've had numerous psu calculator show completely different results;

Specs motherboard- seen peak of 150W +
gfx(gtx 260 core216) peak 300W
Phenom II 720 peak 150W+
2 HDD 40W
DVD burner 30w

this shows
i need ~670W, i know i don't need that much, where are the benchmarks coming from.
ex: phenom says 95w, on some forum the power consumption goes to 150w ??

Clarify plz

really? 670w? That doesn't seem right to me.... if i were just going on my intuition i'd say you wouldn't need more than a 550w for that system (assuming a good quality antec or something like it). I reccommend (if you are being paranoid, this may well be overkill) a pc power and cooling 610w unit... damn good quality those are by all accounts

A motherboard that uses 150W? A GTX260 wouldn't use 300W either. Two in SLI use a bit more then that, the GTX295 uses a bit less. The 720 is a triple is it not? If so, it won't use 150W either. Seems like whoever is telling you this wants you to buy a huge PSU. Look for something in the 500-650 range, make sure it has at least 34A on the 12V rail. (unless you want to SLI those GTX260s, then you'll need more.)
