PSU blew up and killed my motherboard it seems

I was in the other room when I heard a *pop* noise come from my computer room. I also noticed a quick flash of light. I went into the room to find my computer off and wouldn't turn on. I guess something blew up inside my PSU. When I removed the PSU, I heard something rattling in there. This black piece fell out, looks like the top of a circuit or something: https://drive.google.com/file/d/0B1YGPnD1SHdeUkNnUlRmQUdyWFM1SU81ZWNhNmhlYXoweFhR/edit?usp=sharing.

After that, I took the PSU out of an older computer that I knew worked. I hooked up only the motherboard power to the PSU (didn't hook up any other components) and plugged in the PSU. No lights on the motherboard. I'm assuming the PSU fried it when it died.

Anything I'm missing here? I don't think I should have to power the GPU or anything in order for the mobo lights to turn on, right? If the mobo fried, what are the odds it took other components with it?

I'm thinking I'm looking at a rebuild at this point. Sucky.

More about psu blew killed motherboard
  1. Hard to say, would help if you list all the components!
  2. WHAT wattage was the power supply from the one unit to the next? The one that was powering your pc that blew up what or how much was it and was the power supply from the old unit enough to power the unit?

    The one that blew was 550 and the old one I had was 500. Should be more than enough to power just the motherboard I would assume, unless I'm missing something. Like I said, I was just trying to get lights on the motherboard without actually turning the PC on.
  4. Still we do not know what hardware we are talking about. Big difference between a Corsair PSU and a Logisys since I would not expect anything but fireworks from the latter! Basically same size does not mean equal!

    It was the OCZ Fatal1ty PSU.
  6. And the second one? And what are the components we are dealing with?
    It is simple the more info you give the better help you get!

    Off topic now I am scared have a Fatal1ty 550 few years old. Is yours still in warranty since last chance to claim RMA they have filed for bankruptcy?

    The other PSU is an Antec Earthwatt. Not dealing with any cheapo PSU's here. I didn't list other components because I'm not really sure what they have to do with the question I am asking. I'm really just asking if the motherboard lights should be turning on by only plugging in the mobo power and not any of the other components.

    I didn't know about their bankruptcy, but ya, I have the same one you have and it is also almost 4 years old or so I believe. I don't know about the warranty, but if my mobo is dead (which it seems) that probably won't help me much anyway.

    I would say if the antec was good then its your board was the antec working in the other system are your specs the same as the system the power supply died in the specs help us help you! example one pc you have a radeon 7950 in and the power supply died the old system had a old power supply that didn't need to power the vid card hence the power differences..
  9. Well at minimum you will have to hook up 24 pin and 4 or 8 pin CPU power!

    Yes, the Antec is working fine. I'm using it in the old computer that I am on right now.

    Sorry, maybe I worded the question poorly.

    If I removed the GPU/memory/HDD from the mobo, I should be able to plug in the mobo power and the motherboard LED's should light up, correct? I am *Not* attempting to power the PC on at this time; just plug it in with the PSU on.
  11. pull the gpu the cpu the mem and unhook the dvd and hard drive if you don't get any lights ect probably the board is toast.
