600w psu too low for new computer?

[Zalkiden]

I have a 600w corsair psu that's about 1 year old. I'm building a whole new comp. However, as I kept adding parts I started wondering if 600w was enough power. Perhaps these forums could help me out. All items on Newegg.

Thanks for the help in advance.

No, a 400W PSU could drive that.

Lots of people (particularly the ones who want to sell you things) will try to make you buy MOAR WATTS. The truth is that any modern computer that's not running SLI could be run off a good quality 400w PSU with a good margin. There just aren't that many things in a computer that draw that amount of power.

A 600W will be more than enough.

Running my computer right now using 314-322W. That's with three monitors included (100W and 35-40W x2) playing a movie, running some stuff in the background as well as a minecraft server.
