Upgrading GPU/CPU on Omen Elite Tower Desktop Need compatible 600W or 800W PSU Germany

[EdwardTMz]

Hello everyone,

I am looking to upgrade the GPU and CPU in my HP desktop system, but I am currently limited by my factory 400W power supply. I need help finding the exact HP spare part numbers for compatible 600W or 800W proprietary power supplies that will fit my chassis and motherboard layout.

Here are the exact specifications and part numbers from my current configuration:

 My Current PSU Part Number: N97955-001 (Regulatory Model: PA-3401-3HB)

 Specs: 400W, 800 Plus Platinum

 Motherboard Connectors: My system relies on the modern proprietary layout consisting of one 7-pin inline connector (PWRCMD) and two 4-pin square connectors (CPU power).

 My PC Product Number: 462D4AA

Could anyone please provide the official HP spare part numbers for the 600W or 800W power supplies that share this exact same 7-pin + dual 4-pin motherboard connector configuration?

Thank you in advance for your help!

@EdwardTMz,

Welcome to our HP Community forum!

Yes, I can assist you with locating compatible higher-power supply units to upgrade your 400-watt (p/n: N97955-001) power supply. Based on the available information, your PC is not compatible with an industry standard 24-pin ATX power supply, based on the presence of the proprietary 7-pin "P2" power connector.

Btw, the PC product number: 462D4AA you provided, does not yield a result in HP's PartSurfer.  If you could provide the following information: type System Information in your lower Windows search bar, click on the System Information app, and look to the right of: "System Model" and "BaseBoard product" and provide that information.

I think this 700-watt power supply with p/n: P02281-001 / PA-5701-1 / L04107-001 is probably compatible, but I need additional information in order to ascertain that.

It would also be very helpful to provide a link where your PC is shown, including a picture of the PC's rear.

Kind Regards,
