PSU and Stability Issues on HP Pavilion Gaming - TG01-0023w

[SupremeRAMY]

Hello,

I’ve been experiencing issues with my HP Pavilion Gaming - TG01-0023w for over a year now, including crashes and freezing. Sometimes these issues happen rarely, but at other times, they occur more frequently. I’ve visited two different technicians, but none have been able to identify the problem despite several checks.

Recently, I asked ChatGPT for possible causes, and it suggested that the power supply unit (PSU) might be the issue. After running tests with OCCT, the +12V line showed a voltage of 6.58V, which is very low compared to the normal range for this line (12V +/- 5%).

I’ve attached the test results for your reference. I’m wondering if anyone here has experienced similar problems or can confirm whether the PSU is likely causing the instability. The computer uses an HP proprietary motherboard with a 4-pin connector instead of the standard 24-pin ATX connector, which makes it difficult to find a compatible PSU.

I would appreciate any help in confirming if the PSU is indeed the problem or if there are other possible solutions.

Thank you in advance!

@SupremeRAMY,

Welcome to our HP Community forum!

According to HP PartSurfer, your HP Pavilion Gaming Desktop PC TG01-2000a (2Z6E1AV) is fitted with a 500-watt power supply (p/n: L81009-800 or: L77487-001 / L89233-001 / L77487-003) -please verify.

Yes, it is entirely possible that you could have a failing or faulty power supply, but there could be a number of other causes as well, including your motherboard, RAM, graphics card and (less likely) your processor.

To be honest, it is quite challenging to troubleshoot it.

Personally, I would completely strip your system, meaning, removing all components and scrutinizing them for any visible damage such as your processor and processor socket, looking for any bend pins or debris stuck somewhere, using a quality thermal paste (such as Arctic MX-4), then trying to run your PC with one RAM stick, and then switching to another RAM stick, etc. in order to pinpoint/replicate your issue. I would use compressed ("canned") air to clean out every component, including your power supply.

Kind Regards,

Thanks for reply!

I want too mention that every thing has been tested but the psu and motherboard.

@SupremeRAMY,

All right, I have been there, done that, so to speak.

Best way to troubleshoot this is to get a replacement power supply, if you can, and check if that is/was the issue.

See if you can purchase it from a seller/eCommerce site that would allow you to return the power supply if your issue continues.

@SupremeRAMY,

The L04618-800 and 942332-001 are interchangeable, and yes, this 400-watt power supply should be compatible with your TG01 desktop:

Link: Power Supply Cross Reference for specific models - HP Support Community - 7483923.

Check the "P2" power cable config of your current power supply: black, empty, grey, green, empty, empty, empty.

Hi,

I just wanted to clarify that I mentioned the wrong computer model earlier in the thread. My actual computer is the HP Pavilion Gaming Desktop TG01-2032no (567L1EA#UUW), not the one I initially mentioned.

I'm considering ordering the Corsair CX550 ATX 550W PSU, but I'm unsure if it will fit my computer. I know this PSU uses a 24-pin ATX connector, while my computer requires a 4-pin connection.

I plan to use a 24-pin to 4-pin adapter, but before I place the order, I wanted to double-check if you think this setup will work.

Additionally, I'm thinking about canceling my current order and opting for this PSU instead, as it has more wattage and is cheaper. Do you think this would be a good choice?

Thanks for your help!

Best regards,
Rami

@SupremeRAMY,

Please verify that your PC is fitted with the Erica6 motherboard (with SSID: 8906), fitted with an AMD processor: type in system information in your lower search bar, and click on the System Information app, and look to the right of "BaseBoard Product".

The proprietary HP power supplies as mentioned are compatible with the Erica6 motherboard.

I have no knowledge of the existence of a "24-pin to 4-pin adapter" for your PC, so we need to dismiss that idea unless you can show me (link) what adapter you are referring to.

Yes, an ATX Corsair CX550 power supply is very nice, but as mentioned, it is not compatible with your motherboard.

Kind Regards,

Hi NonSequitur777,

Thank you for your continued assistance. I have verified that my PC is equipped with the Erica6 motherboard (SSID: 8906) and an AMD Ryzen 7 5700G processor.

I have canceled my previous PSU order in hopes of finding a better option. I'm now seeking a 500W or higher PSU that is compatible with my system and will support my RTX 3060 graphics card.

Could you please recommend a budget-friendly PSU suitable for my setup? I find this process a bit confusing and would greatly appreciate your guidance. I am located in Sweden, so I would need a PSU that can be delivered here.

Additionally, I have found the following PSU options but am unsure if they are suitable:
