Power Supply Replacement

[ianththo]

Hi my power stopped working and I had a friend help me look at it and take it apart and he said I just need a new power supply, I was looking online and it says for the computer I have which is a HP Pavilion Desktop 590-p0076, and online it says I need a 310 W Gold efficiency power supply? Do you sale these? Or can I use another power supply?

@ianththo,

Welcome to our HP User Forum!

Your HP Pavilion 590-p0070 Desktop PC (3LA18AA) according to: HP PartSurfer, can be fitted with either the 310-watt L03980-800 or the 310-watt L64961-800 power supplies.

You can purchase either of these units online, such as here:

L03980-800: https://parts-hq.com/shop/l03980-800-power-supply-psu-310w-sff-es-sirius-gfx-g-792584?search=L03980-...

L64961-800: https://parts-hq.com/shop/l64961-800-power-supply-psu-310w-sirius2-ent19-full-range-842949

@NonSequitur777 I also would like to get a new fan would you happen to know which ones to get? There is one fan on the back blowing out and one inside I'm guessing to cool the inside?

@ianththo,

Yea, there are indeed two cooling fans, and according to: https://partsurfer.hp.com/partsurfer?searchtext=3LA18AA&searchby=product, they are -depending which one(s) you need:

1.) CPU Heatsink cooling fan: HP L14643-001, which you can purchase here, for example: https://www.ebay.com/sch/i.html?_from=R40&_nkw=hp+L14643-001&_sacat=0&LH_PrefLoc=2&_sop=15.

And:

2.) System rear cooling fan: HP L15757-001, which you can purchase also via eBay here: https://www.ebay.com/sch/i.html?_from=R40&_trksid=p2334524.m570.l1313&_nkw=HP+L15757-001&_sacat=0&LH....

Hope this was helpful.
