PSU Power Needed?

Hessian · 31 Dec 2007 at 11:34

There's no PSU section in forum :-/ But anyways, I'm looking at a new PSU and after all the good things I've heard, Im gonna go for the Corsair ones, but not sure how much power I need.

My current spec is:
Asus P5KC mobo
Radeon X1900XTX 512mb Card
3 SATA HDD's
1 SATA DVD RW Optical Drive
Single 19" Widescreen monitor, but wanting to buy a 2nd in very near future.
2 Gig Ram.

Think that's all. What's a suitable Wattage for that? Thanks.

http://www.extreme.outervision.com/psucalculatorlite.jsp is always a good place to start, just put in what ya got and it will work it all out. You may get away with the 450w one but I'd recomend the 520w if you ever upgrade again in the future...

Ah yeh, the first question is the CPU, I left it out of the list

I have a 2.66ghz Core2Duo

The HX520 will be more than enough for you needs.
I have one & it is rock solid stable & silent.

More important than the overall power is stability & the current it can deliver on it's various rails. As an example my X2@3GHz system with an 8800GTS and water cooling draws between 140W idle and 250W load, a long way short of the rated output of the psu - but another +1 for the HX520.
