being Corsair a renowned brand and HX a professional series, it's worth noting that Seasonic ss costs way more while offering considerably less power; this happens because this given Seasonic PSU is one of the most expensive € for W in the market; so you can get away with it because it's absolute top of the line and, regarding it's output, extremely expensive as well.

this "it's their money and their choice" argument is a 2 sided coin; to give an example the Seasonic ss 460W offers the utmost efficiency and stability; a 115€ Corsair TX 850W, while not as good is a quality one and can SLI 2 GTX 580; the Seasonic cannot.

bottom line is, if you go for nothing but the absolute best then about 450W will suffice; go for a good mid-range and 550/600W mark, depending on quality, is perfectly reasonable and recommended; go for entry series, 600W may lead to trouble (and above that as well)

p.s. - i just can't understand how someone could disagree on this, especially if they have a GTX580 and 550W PSU on their sig...

Nice try to turn tables ... but I'm happy that we agreed, in the end. It is useless to go for a 750W, lest an 850W for a single GTX580. OP's CX600 was good enough.

PS: BTW you cannot compare the prices of a fanless PCU with a traditional one ...
