This is my first post and I'm glad I found yall. I have an older computer that has worked fine for the past couple of years, till I started having problems recently. I've researched and com to the conclusion that my PSU is going out. Now for my question. My computer is labeled as a compaq presario 4090us but when I use Belarc I'm told it's a 5108us. Thats the only difference that comes up. The PSU going bad is for the 4090us what I want to KNOW is if I need to replace with the same PSU or go with a different on? I appreciate any help you can give me, Thanks.

If you download and RUN Everest Home it should correctly identify it. If it is the same as Belarc I would go with that.

The replacement power supply must be able to physically fit appropriately in the case. Compaq's are average and usually of barely sufficient wattage. Can you see from the power supply in there the make, wattage and perhaps model number?

If it is a 5108US then this is the info on it:
