GPU, CPU, and PSU upgrades

[chanio0o]

I have an hp pavillion gaming desktop tp01-2000a. I am wondering if I can upgrade the psu and where I can buy one. I would also like to know if there are any gpu and cpu upgrades I can make without having to change my motheroard. The only changes I would like to make to my pc involve the gpu, cpu, and psu. Do you have any recommendations I can get?

@chanio0o,

Welcome to our HP User Forum!

You are asking for three specific answers, and I will do my best to meet your expectations.

Your HP Pavilion Desktop PC TP01-2000a (2Z6C8AV) is fitted with an HP Erica6 motherboard with SSID: 8906 (HP p/n: L56021-605) and a 400-watt power supply with HP p/n: L69242-800 (please verify).

The best/fastest processor for your desktop, looking at real-world User benchmarks, is the AMD Ryzen 7 5700G.

With regard to a power supply upgrade, looking at your 400-watt power supply dimensions, I could not find an HP power supply upgrade -but there is a work-around, and if you are interested, I could explain in a follow-up post.

For GPU upgrades, looking here: https://www.userbenchmark.com/System/HP-Pavilion-Desktop-TP01-2xxx/234647 (look at the HP 8906 User benchmarks with AMD processors), the most powerful HP System Pavilion Desktop TP01-2xxx is fitted with a Nvidia RTX 2080-Ti.  However, to power this card, it would require at least a 600-watt power supply. Again, if interested in how to do that, let me know (follow-up post).

If you want to stick with your 400-watt power supply for the time being, this PSU could power an HP RTX 3060 12GB GDDR6, as I have shown in this legacy HP desktop upgrade project: https://h30434.www3.hp.com/t5/Desktop-Hardware-and-Upgrade-Questions/Upgrading-to-an-HP-ProDesk-600-..., and it runs very well.

Hope this was helpful so far.

Kind Regards,

Okay thank you. While keeping my psu, I can upgrade my gpu and cpu to a AMD Ryzen 7 5700G and a HP RTX 3060 12GB GDDR6.  Also, could you please explain the work around for the psu?

@chanio0o,

Yes, I would be happy to explain the power supply work-around to make any graphics card roar like a T. Rex, and here is the main component to make that happen:

Behold, an ATX PSU 24-Pin to SATA power supply adapter card.

What this means, is that you can ADD a secondary synced, external ATX power supply, up to 1,000 watt.  You keep your original 400-watt OEM HP power supply, but your proprietary PSU is connected to an externally parked ATX power supply by a 15-pin SATA power cable to an ATX PSU 24-Pin to SATA power supply adapter card, which provides a signal to power up the secondary ATX PSU whenever you turn your PC on, or off, when you turn your PC off.

With this ATX power adapter card (see picture), you can ADD a discrete, external ATX power supply to your PC. All you have to do is connect a standard ATX PSU's 24-pin power cable to the adapter card and connect the adapter's SATA connection to one of your proprietary's PSU SATA connectors. Done. Once connected, the secondary PSU is synced with your PC -meaning, that when you start up or power down your PC, the secondary power supply switches on and off at the same time. Nice!

Summarizing:

1.) - Your existing PSU stays.
2.) - Connect one of the proprietary HP PSU SATA connectors into the corresponding power adapter card plug.
3.) - Connect the Secondary PSU's 24-pin ATX power connector into the adapter card 24-pin plug.

4.) - Connect your eGPU with the secondary PSU's 6/8-pin(s) PCIe power connector cable(s).
5.) - Whenever you turn on your computer (and thus power on your Primary PSU) this adapter will automatically turn on your secondary PSU, powering whatever is plugged into it. And when you power your computer off, it will automatically power off your secondary PSU.

6.) - It is SAFE: the ATX to SATA adapter card has power isolation technology built in to prevent any power issues.

Here are two links of HP upgrade projects where I used this method:
