This morning, my PC decided not to switch on. I pressed the power button and there was no response whatsoever. I was confused, and wondered whether something simple was missing from the process. I looked over it, the plugs and extensions were all connected right, the switch in the back was on. Yet no response.

I booted up the old, decrepit laptop to look up solutions online and I followed their instructions to a certain point - I checked the inside of the PC to ensure that everything was connected up right and that power was going to the motherboard and all that - check, and then I chose a new plug lead to put in the back just in case that was the broken link. That's when things got interesting.

It was plugged in, and when I turned the switch in the back to "on" there was a flash and a pop and some weird smell from just under my finger, where the PSU is. It knocked out one of the circuit breakers in the fuse box downstairs when doing so.

So. Would it be fair to surmise now that my PC's PSU has blown out, so to speak, and that I should buy another one of the same make to replace it post haste?

Your psu would appear to have bitten the dust, what was the make and model as it may not be the best idea to replace it with a like for like, and you might also need to check that no other hardware gotten taken out when it blew.

It was an EZCool 650W 12cm Fan Blue LED Power Supply.

How can I check whether the rest of the hardware is fine or not?

I would advise looking at Seasonic, Antec, XFX, or HCG for reliability. Once you have a new power supply you will soon know if anything is gone, but you could test some things in a compatible computer IE ram and Gpu.

Okay, PSUs tend to be the same size and fit in the same place, right? Am I gonna have to look for a special kind to fit with the config I already have?

My System


Given the PSU you already had, which was an after market unit, it's safe to say another after market unit will fit in its place.
As suggested, go for Seasonic, Antec HCG or XFX.

As noted, your previous PSU was ATX so any ATX unit should work.
Your EZCool PSU was lower quality and may have damaged other components when it failed but that can only be verified when you install a new PSU.
If we know the Brand & Model of your components, as requested by joeten in Post #6, we could recommend a articular PSU that will meet your requirements.

It always amazes me that builders include lower quality PSU's with PC's they build. It's just poor business and certainly doesn't encourage repeat business.
You want to be at 550W minimum with a good quality PSU.
Best bang for buck: SeaSonic S12II 620 Bronze 620W ATX12V V2.3 / EPS 12V V2.91 80 PLUS BRONZE Certified Active PFC Power Supply - Newegg.com
