PSU Sparked and Died, so I need a new PSU and (I think) CPU and MOBO

Hey, all.

I've needed to purchase a new PSU for a while, but it seems fate has forced my stingy hand. While playing some Overwatch, my PC shut down, and when I tried to turn it back on, the back of my PC lit up a stark white.

Therefore, I'm in the market for a new PSU, and (I think) a new CPU and MOBO.

This is my setup with the new MOBO, PSU, and CPU added on:

What do you guys think?

Also, to explain why I'm fairly sure both my MOBO and CPU are shot, I took it over to Bestbuy, and we were able to get it to power on, but not produce any video signal. Further, it didn't make any diagnostic beeps.

Thank so much for looking this over, all! I appreciate it!

Let me know if you have any questions.

Well, if the PSU...

If you're still in the market to buying a new PSU, that means you were able to get it to power on with the same PSU that lit up a spark(?)... so unless it was a diferent PSU you shouldn't expect the same one to power up normally with video and bios beeps.

And as far as I know, the low DC voltage a PSU produces is not enough to make a stark white spark... so it must have been produced by AC power which is on a different circuit, and must have discharged to ground on the PSU housing... so I'd say it's unlikely to have affected the mobo and/or CPU.

So yes, first buy or at least borrow a different PSU to see if the PC powers up normally or not, so you'll know what components you really need to replace.

Hey, guys.

So, I was with the Best Buy associated when they did the test; they used a new PSU to power on the computer, and while fans spin up, there isn't any video signal being produced by the MOBO or GPU.

I've been needing to do an upgrade for a while, so I think I'll grab all the components I need at once regardless of whether or not the MOBO or CPU is finished and test again once I get them.

As far as the spark goes, this PSU's power output previously melted, and my dad jerry-rigged an extension cord to it; I'm pretty sure one of the exposed wires burned, but it worked for months, and my dad knows what he's doing.

Anyway, do you guys think the CPU, MOBO, and PSU are good options?

Thanks again!

Yeah, I know that it's overkill with this build, but it's only $10 more, and it gives me some room for upgradeability in the future.

Well, if the PSU power output burned, it must have carried way more power than normal... so that would probably do the damage.

My opinion on the new components?... they are good options for the price range, check your CPU options if you'd like a bit better CPU.
