PSU questions

hello,

HP Pavilion 752n needs a PS.

Mobo: TriGem 129504 (Imperial)
Socket: mPGA478
Processor: 2.0 GHz P4 400MHz
Board Form: uATX
Graphics: Onboard Intel
Sound: Creative Sound Blaster Live CT4830
Drives: 1 CD-R, 1 DVD-ROM
Storage: 1 60GB Maxtor HD
Other: PCI Firewire Card

The PC originally had a 200w PS; will a 150w PS be sufficient? How can
you tell?
Also, what are the basic principles regarding PS wattage selection?

Thanks,
amc

This is probably a mATX or is it PS3 form-factor (like std
PS2 but shorter)?

Don't downgrade the wattage, they're hard enough to keep
working long-term as it is (as you have found, yours
failed?).

Get a quality name-brand rated for at least 200W, with a
high 12V amperage rating... about 10A @ 12V. If it's a PS3,
here's an example,

and here's an example of what you'd want to avoid - a
generic with an inflated wattage rating,

Browse around Newegg's site for more options. Note specs
and model #s for other sources if you wish (or need) to
purchase elsewhere). Another option might be buying a
larger case (to accomodate std. PS2/ATX PSU), with a
significantly higher capacity PSU, as soon those HP parts
won't be worth much and you can pull the board/CPU/memory
and reuse the case & PSU to rebuild the system.
