So I have a HP EliteDesk 800 G3 SFF running Ubuntu server OS with a 250W PSU but I want to add dual SATA HDD drive with an RPM at 7.2k at least 10 tb each. With a  I7-7700 and 32gb ddr4. I was building it using new eggs power supply calculator and it tells me it requires at least 387 Watts.

Where can I find an adequate PSU that fits my needs?

@Dave3123,

 

Welcome to our HP Community forum!

 

Here is the power supply upgrade I would strongly recommend:


500-watt power supply with p/n: L77487-001 / L89233-001 / L77487-003.

 

PLEASE NOTE: Make sure that the power supply's 7-pin "P2" has all 7 wires, DO NOT buy a 500-watt power supply model with three wires to the P2 power connector!

 

Here is an outstanding eBay purchase example from a trusted Seller (99.9% positive) : New For HP 500W Power Supply PSU L77487-001 L89233-001 L77487-003 PA-5501-2 US | eBay.

 

And there you go.

 

Kind Regards,
