Hp gaming desktop 690-0034

Hello, I want to upgrade my graphics card and power supply on my Hp gaming desktop 690-0034, but I'm not sure what kind of power supply to get that is compatible with this computer since it is a pre-built pc. any help at all would be very much appreciated. 🙂

@T-camp1 , welcome to the forum.


The motherboard (Sunflower) in your computer is HP proprietary.  It has a 4-pin power connector; not the standard ATX 24-pin connector.  Therefore, only a power supply unit (PSU) sold by HP will work.  Here is a Power Supply Cross-Reference guide to help you identify a compatible PSU:


It appears the only upgrade would be Part # L05757-800 (500W).  This will allow you to get a better video card because it has a PCIe 6+2 supplemental power connector.
