I am new to this forum. This is my first post. I have a brand new PC I bought from Origin in March of this year. Last week I pressed the power button to turn it on from sleep and I hear a pop sound. Now nothing works. No power or anything. I did not smell anything burning. I'm pretty sure it is the PSU that went bad. If it is the PSU, I hope it didn't take anything with it. Does his sound like it was the PSU? If it is the PSU, what would cause it to go bad so fast?

I know the new PC is still under warranty, so I should be able to get it fixed. But I will have to ship it to them at my cost. They told me I also have the option of taking out the PSU myself and just send that back to them. I did take the PSU out of my PC, but have not taken off the cables yet. I'm not sure yet if I will send just the PSU back or the whole PC. My concern is if I just get a new PSU, what if when the PSU died, it took out other components. According to the Origin tech I have been talking to via email, it does sound like the PSU died and although it is possible the it took out other components when it died, this is unlikely.

My new PC's PSU is a Corsair RM850x Gold. The CPU is Intel Core i7-13700K . The graphics card is AMD Radeon RX 7900 XT.

Could an underpowered PSU cause the PSU to go bad? I found this web site on how to select a PSU. It It recommended getting the power draw of the GPU and the CPU and add 150 to it for the motherboard, fans, etc. Then it said that PSU’s don’t operate at the highest efficiency when at full load, so it recommended adding another 150. What I found was my GPU has a power draw of 300W and my CPU has a power draw of 364W. 300 + 364 + 150 = 814. My PSU is 850 watts, which is pretty close to 850. If I add another 150 to 814 I get 964. Maybe I should replace it with a 1000 watt PSU. Thoughts?

If I did replace it with a 1000 watt PSU, if I got Corsair's 1000 watt PSU, would I be able to use the same cables? I would prefer keeping al the cables connected to the motherboard, etc and just plug the cables into the new PSU.
 
I thought instead of trying the paper clip test I would get a PSU tester. The tester is supposed to light up, showing voltage, etc and beep. But it is showing nothing. I'm not sure if the PSU tester not doing anything means the PSU tester is bad or that is telling me my PSU is bad. The instructions that came with this PSU tester are terrible.

So then I tried the paperclip test. The fan does not turn on. So I think this means my PSU is bad. Thanks lojikal.

You're most welcome mate. Please see Tom's hardware PSU Guide here: https://forums.tomshardware.com/thr...pply-discussion-thread-toms-hardware.3212332/
This should help you choose a reliable PSU replacement.
 
The Corsair RM850x is a good quality power supply. Failure is a possibility with any hardware, but certainly not expected out of a unit like that. In this case I would bite the bullet and send the entire PC back to rule out the possibility that something else hardware related led to the PSU failure.

I got my replacement PSU, which was the same model as the one that died - Corsair RM850x. I kept all the cables from the old PSU attached to the motherboard, etc. So to hook up the new PSU I just had to plug the cables into the PSU. My new PC is now working again. I just hope it lasts.

I still wonder why it went bad. I know PC parts can go bad, but they should last more than 4 months. I wonder if it was just defective and its days were numbered.

Even quality components have failure but at a much lower rate than low quality items. Looks like you just got unlucky and got hit by one of those rare failures.
