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 |

How can you tell? 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. Also, what are the basic principles regarding PS wattage selection? Buy quality. Sorry I've gotta go... |

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, http://www.newegg.com/Product/Produc...82E16817104903 and here's an example of what you'd want to avoid - a generic with an inflated wattage rating, http://www.newegg.com/Product/Produc...82E16817338009 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. |
