PSU BLEWED UP

[Sagnik Pandit]

Still in a bit of shock and would really appreciate any help.

Here's what happened. So i was building it with my two mates. We connected everything up, then went to test to see if everything was booting before we do all the cable management etc. Hit the power button, but only the rgb on the ram was lighting up. So then we tried disconnecting the power to the gfx card and only leaving the motherboard and cpu connected to the power supply. Still no luck. Finally we unplugged the extra 4 pin for the cpu, tried to turn it on... then *poof* power supply blew up. The lights even dimmed. Immediately switched off the psu and and unplugged the power.

At first we thought it may be a faulty power supply, but upon further inspection, it looks like we connected the PCIE cable to the CPU 8 pin on the motherboard and the EPS cable to the gfx card.

Would this cause the power supply to blow up?

I'm hoping the power supply took the brunt of it and did what it was meant to do. Just really worried that i did damage to the graphics card, motherboard or cpu.

Would they have been fried too if that was the case? i.e. there would be damage elsewhere?

Also do you think this would be covered in the warranty? These psu's are not cheap and i went way over budget already

I'm too scared to touch the pc anymore, gonna take it to a professional to get it running.. hopefully.

Here are the parts i used:

PSU: SilverStone SX1000 SFX-L Platinum Modular 1000W

CPU: Ryzen 9 5900

GPU: Aorus Extreme 3080

RAM: 4 x 8 (32GB) Corsair Dominator RGB 3600

MB: Gigabyte x570 aorus pro wifi

Thank you for reading.

 

*edit* thanks for all the replies everyone. It fuckin hurts but i'm prepared for the worst now. Gonna try to sleep since there's nothing i can do now.

I could almost guarantee that those different connectors do not have the same wiring layout as each other, so odds are too much power got sent over and blammo. It could be very likely that the CPU, GPU, and motherboard are all fried, but maybe you got lucky and it didn't. Unfortunately I'm not entirely sure if you guys would be able to try and RMA it considering it was user error, but I suppose it depends on the company so I'd try to at least. My advice; take it to a professional ASAP, see if they can at least test the other components so you know if it's a total write off or not. Best of luck.

Chances are you've already fried your motherboard and GPU, because you've connected wrong cables. And while you can plug the PCIe cable into EPS socket because notches on them are somehow physically compatible (not electrically), you have to really force the EPS cable into PCIe socket to do this. No, it wouldn't be covered by warranty. Why has PSU blew up is another question, but at least the PSU should be covered by warranty as no matter what it shouldn't blow up just by you plugging the cables wrong if it was designed properly.

Well, you created a short circuit between 12v and ground on the CPU connector and on the video card connector. 

You may have damaged the motherboard and the video card, but chances are they're fine or just have some fuses/current sense resistors blown so it's repairable.

The cpu is probably fine, same for ram, it should be fine.

 

The power supply started giving power but the over current protection should have kicked and stop the power supply.  If there's no such protection (on a 1000w psu would be a bit worrying) then the over power protection should have kicked it, to protect the transformer and mosfets inside the power supply from overheating by giving more than 1000w to components. 

Worst case scenario, the glass fuse in the power supply blew up and disconnected the power supply from mains and therefore no more power going into the cables.

 

Have the psu tested by someone else (without breaking warranty seals) and if it's not working, return the psu for warranty and just said you plugged it in and made smoke, don't go into details. If you're lucky, they'll replace it.
