Recommend me a PSU for Intel P4 Prescotts

[sawyen]

I'm building an office rig for a new kid thats coming to do a PhD.. Thought of just getting him a simple P4 630 with the usual rubbish and onboard gfx.. wat sort of power rating are we looking at? If I could get away with 300W.. I might settle on one of AOpen's microATX cases and be gone with it.

Recommendations please..

EDIT: Also, will a 300W suffice for a Celeron 2.66Ghz? + the usual stuff and onboard gfx? This is entirely another project I'm working on for my student..

Not even a whisper?

I think the 300W should be fine for the celeron.

Not sure about the prescott, you might get stability problems under load. I'm guessing it would be more expensive to get an a64 and one of the new nforce4 boards with integrated graphics or his work requires the p4 as from your previous posts you are quite knowledgable.

Perhaps a good 350w psu and upwards? Scan sometimes have a 350w older model enermax for just over £28 on today only. I've had that psu in the past and it's been very good. Having said that take a look at www.silentpcreview.com in the power supply guides section, they have measured the power requirements for a variety of systems under load and at idle and you could use to see if a 300w psu would be fine.

well, unless we're talking about dual core or dual opterons, the stuff we do kind of favours Pentium 4s. As much as I hate it, it does help to have 2 logical cores as our processing work will be going almost 24/7 and we will still need to use office and possibly browse the internet whilst waiting for our analysis to finish.

I was thinking the same thing, Since I run a P4 520 in the office with a gig of memory (Dell stuff) and they're only giving me a 350W supply. I suppose a good 350W should suffice..

Any other recommendations?
