Hey guys,

I have a HP a1440n computer where I am confident the power supply has went out. It has been "on the fritz" for a while, randomly shutting off, and then after I unplug it for a few minutes, it is fine again. It has went off and won't come back on at all now. When I do plug it in, it emits a high pitched whine.

I looked online and saw that I can purchase one for around $28, but I have a Compaq here that I may could use. The model is a B110. Is there an online cross reference guide?

Thanks!

Jeremy

Hello,

I would say replace that power supply as soon as possible. PSU units have a high amount of votages and can damage your components and you. Any power supplies are compatible. PSU's have standards so they are compatible. You only have to get a exact Power supply if you get a system with a non standard case or voltages

your desktop is an ATX standard case so any of the power supply will work.

To answer you question. May sure your Compaq PSU is ATX standard and is at least the same or greater of the MAX Wattage of the HP. you can replace it. May sure your P1 connector and your ATX connector is the same of the Compaq power supply

In order to transplant the PSU you should have

same or greater wattage and
One 24-pin ATX power connector (some have 20pin)
One 4-pin ATX 12 V power connector (all should have this connector)

If you get a new PSU Its highly recommended to get a solid one. For example you can go to best buy(not cheap) newegg, amazon, tigerdirect

Hope this helps

Situation resolved. I took a power supply from another unit, and we're good to go. Thanks!
