@wainaina1,

Welcome to our HP Community forum!

HP has made it very challenging indeed to provide information which compatible power supply upgrade options are available for your HP EliteDesk 705 G4 Microtower beyond the stock 250-watt PSU with p/n: L29869-001 "SPS-P/S MT 250W ENT18 92pct. HV 12V 1OUT".

Even though HP's specs as found here mentions a 400-watt power supply, no part number(s) are provided.

Looking at a picture of the 250-watt power supply as seen here, I believe I can tell you that based on the "P2" (7-pin) power cable config, these 400-watt power supplies with p/n: L04618-800 / 942332-001 / L69242-800, as well as a 500-watt power supply with p/n: 901759-013 should be a match for your PC.

Kind Regards,
