PSU for x2 slave?

[jow]

Hi,
About to buy/build a couple x2 4200 render slaves and wondering what the recommended PSU would be?
The last x2 i built, i put a 500w PSU in but thats a workstation/gaming machine with a high end graphics card in.
Can i get away with 400w or lower?

Cheers.

checking back an a psu review (03/2006):

they measured pc components for their power consumption:

									Max	 |	Average
Highend Dual-Core CPU: 		140W	90W
Highend Graphics Card		100W	60W
Mainboard						25W		20W
1 Gig of RAM					10W		8W
1 HDD							30W		25W
1 Cooler						3W		3W
DVD								15W		5W

excuse the strange layout - thought the code mode would use equal spacing
depending on your intended system you can sum those up yourself

you shouldn't run the psu at 100% - lowers its life expectancy considerably
they suggest reserving an additional 100W to be sure (and for future components that will draw even more power)
-------------
suggestions for 500W psus (depending on where you are it might be difficult to get those - the review was in a german magazine):
prices in euro (street prices should be somewhat lower)
1. Be quiet!
BQT P6-520W
120€
2. Seasonic
S12-500W
130€
3. Q-Technology
GT-08560G/Dustproof
145€
4. Enermax
Liberty ELT500AWT
100€
5. Antec
True Power 2.0 500
175€
7. Sharkoon
Silentstorm SHA535-9A
115€
8. Ultron
UN-550 PFC
80€ - their budget recommendation
I have the 400W version of this one and it's really quiet

I really like my Antec Truepowers. They've been in the business for a long time and pretty quiet overall.
