Power supply upgrade

[DREADEGG761]

What kind of power supply do I need for my hp elitedesk 800 g3 sff to run a 120w graphics card? I can use a full height card as I have swapped the case.

Thank you, @BeemerBiker.

@DREADEGG761,

As mentioned, I upgraded an HP EliteDesk 800 G3 SFF, then replaced the motherboard with an HP EliteDesk 800 G4 SFF -and upgraded it accordingly, and again with an HP EliteDesk G5 SFF motherboard: Solved: Upgrading HP EliteDesk 800 G5 SFF Part II - HP Support Community - 8720291.

Anyway, given your question, there are two relevant power supply upgrades available to you: a 400-watt PSU with p/n: p/n: 942332-001, which can be purchased online for around $50 via an eBay Seller: Hp 942332-001 for sale | eBay, or a 500-watt power supply, with p/n: L77487-003, also available online for around $97, such as via an eBay Seller: New 500W PSU Power Supply L77487-001 L89233-001 For HP 280 G8 Pro Z2 L77487-003 | eBay.

Hope this was helpful.

Thank you, I seem to have found what I was hard looking for. Just to be sure - is it sure that P/N:L77487-003 source will work properly in HP Elite 800G3 P/N:Y2Z63AV ??

@Atvar,

My apologies: just returned from vacationing in the Netherlands.

Yes, the 500-watt (p/n: L77487-003) power supply fits/is compatible with an HP EliteDesk 800 G3/G4/G5 SFF:
