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

There are calculators that you can give you estimates, but the ultimate
test is how your usage overlaps with the PSU's performance.

Here's one calculator:
http://www.journeysystems.com/?powercalc

It suggests something in the high 200s. Find some other calculators and
try them out as well. I suspect that most will be geared to
overestimate power consumption, but that seems like the reasonable side
to put the error.

Buy quality. Sorry I've gotta go...

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.
