Do I need a PSU replacement?

[VinSen]

PC turned off, and won't turn back on at all. No power.

Just tried out the paper clip test multiple times on the 4th and 5th pin with the clip side up, and it didn't power on, no fan movement or anything. Did different sockets and power strips with nothing happening. Does that mean it's for sure the power supply that needs to be replaced? I tried the main power cable too on another computer and that worked fine. The only other test I didn't do was the use of another PSU because I don't have one. I can't really test anything with the mobo too if there's no power right? If I do get a new one what's another alternative to this MSI one that's on a similar playing field? Assuming this is actually dead, I thought these were suppose to last longer, not less than a year. The only criteria I know for other PSU is the wattage and fitting the case which is a Phantext XT Pro.

When doing the paperclip test, you've disconnected everything, right?

When I did it, it was only with the PSU, no mobo attached, since that was the end I used for the paperclip in the 4 and 5 pin slots when looking at the clip upside.

Well, you should try with a different PSU then. Or use a PSU tester on the existing PSU.

At least it's under warranty...

I unfortunately don't have another PSU around. This build is my first one, so I only have these components on me. That's the only test I didn't do because I cannot. So does that sound then that it is the PSU being bad...?

Maybe you can get a PSU tester like this?

 

 

Should be cheap on Amazon or some other store(s). If you can get it in a day or two, it might be worth it - even as a tool to have for diagnostics etc.

Yeah well if my case is any indication, I guess most PC builders should have this! Thank you for letting me know about this! I do have another question too since as I've been trying to figure things out I realized something. When I plug in the HDMI to a monitor the monitor itself does respond, yet I still can't get anything actually running. From the monitor responding though, that could potentially rule out the mobo being bad to a degree right?

Can you describe "the monitor responding"?

The monitor is plugged in, light is yellow. When I plug in the monitor to the mobo in the hdmi slot it turns on as if it detects something, but of course can't show anything because nothing is technically "on".  Does that make sense? It pops up briefly with a no signal and blue light when plugged in initially, then shuts off back to yellow.

This leads me to believe you're trying to use the system with a PSU suspected of being faulty.

 

Well, since you already do that, what happens when you remove the GPU and try booting with the integrated graphics?

Yes that is correct, still using the potentially bad PSU which still has shown no sign of life after more trouble shootings I've done (moving RAM in and out of slots, reseating the CPU again, and taking out the CMOS battery and putting it back in).

 

I currently have the GPU removed as well, and it does the same thing as when it's in. Light turns blue, monitors pops in and says no signal, then turns back off. Happen when both unplugging and plugging back in, with and without the GPU in. I'm hoping that's at least normal at this point lol.

Which light turns blue? RGB lighting on the fans? Power LED? Something other?

No RGBs at all in my build, all black. The blue light I mean is the power button light on the monitor turns blue whenever plugging or unplugging an HDMI into the mobo. There's still no response from any LEDs on the mobo when trying to turn it on though.

That's just a monitor thing, not an inication of a signal coming from the system. I'd bet on the PSU and I'd try with a different PSU (at least from a friend or relative).
