How to fix a malfunctioning computer?
I purchased a computer second hand and it arrived by post. Probably not the best decision, but I didn’t comment on that 😂 The sender didn’t unmount any parts—it came fully assembled. Packaging looked fine, no visible damage. When I connected it, there were no reactions. No LEDs on the motherboard or GPU, etc. It seems the PSU might be the issue, though I wouldn’t expect it to fail. It’s possible the sender used bubble wrap without knowing why. The build specs are: Ryzen 7600, MSI 650 gaming Wi-Fi, 16GB RAM, RX 7600, 550W PSU, Phantex G360 case. I have an extra PSU—should I connect it for testing or risk damage? Could I try connecting just the GPU and see if the LEDs activate? Also, since my room lacks grounded outlets, could the PSU not start without proper grounding? Any advice would be appreciated.
Best regards,
CJ
The PSU's make and model (or part number) are unclear. It doesn't require ground to operate, though having it would be safer. The second PSU's make and model (or part number) is also uncertain. Replacing the power cables without reuse shouldn't cause problems. However, GPU LEDs lighting up doesn't confirm the GPU is functioning properly. It's similar to turning on a car's ignition and seeing lights come on without starting the engine—you might assume it works, but it could be different depending on the PSU. The idea is that the PSU might be very reliable, possibly lasting forever.
Thank you for confirming, this helps rule out that scenario.
Corsair RM850x V3 850W
All cables are new and included with the Corsair PSU. Could there be any chance the power cable got damaged during shipping or static discharge?
This check was just to verify if the existing PSU is functioning properly, based on the logic that if the Corsair PSU is supplying power when connected, the original PSU should be active.
No, the assumption here is only that the build is only six months old and the PSU appears more resistant to static shocks and shocks because it’s in a sturdy casing. I’d expect components like the motherboard, cooling fan, and GPU to be more affected.
I still have a Cooler Master 750W from 2014 working well in an older build—this is my first time getting a full computer by mail and I haven’t had any issues before. That’s why I’m concerned about static discharge, as there was bubble wrap inside and the possibility of shock damage.
As mentioned before, the case and interior show no clear signs of damage. I’ll also share a photo of the bubble wrap inside.
Thank you for all your feedback so far.
Here is the information you requested:

That's mediocre quality unit. More like low quality. I'd advise against using it.
And it being dead - is quite a possibility. Though, when PSU goes "pop", there is a chance it killing everything it is connected to (aka the whole PC). And the lower the PSU's build quality - the higher the chance it can happen (both PSU dying and killing components).
Good quality PSU.
👍
I suggest you use this one instead.
No.
Distributing power isn't the PSU's only job. There are far more tasks PSU must do.
Though, to be exact, it's the MoBo's job to distribute power it gets from 24-pin ATX and 4/8-pin EPS. To CPU socket, to PCI-E sockets and to other parts of the MoBo, to make all of it working.
Well, it depends on which part the ESD came in. But PSU's build quality just isn't there. So, PSU being toast is quite likely. And not by ESD or shock, but probably due to it's own accord (namely cheap construction and using inferior components inside).
Not all PSUs are created equal.
Here, two PSUs. Both are 650W and 80+ Gold,

Can you tell me, why Seasonic unit costs essentially double of the Apevia unit?
Also, which of the two you'd use? And why?
My suggestions don't hinder testing a different power supply. They just remove elements that could add to the troubleshooting process.
First, ensure all connections are secure.
If the front panel power lead seems loose, consider shorting the motherboard's front panel power pins.
Bubble wrap was probably added to prevent movement and potential damage to the motherboard.
Since you have a better PSU available, it would be advisable to replace it.
Although an ungrounded outlet functions for most devices, it poses safety risks.
Grounding is essential for reliable power supply operation.
A proper ground connection provides a stable reference point.
It plays a vital role in maintaining accurate measurements.
Low-impedance grounds are necessary, and they should be connected appropriately to avoid voltage fluctuations across the system.
