As I understand it the components that go into PSUs are filled with special Seasonic smoke at the factory. If any of that smoke inadvertantly escapes, the PSU generally stops working. I think if you short Pin 14 (a green wire) on the mobo lead to ground, the PSU fan should spin up. You may want to get a second opinion on this quick and dirty test first though.
Apparently, "Do whatever you like" should NOT be considered authorisation to build my uber rig!
Ok, thanks for all the replies.
Could anyone kind of give me odds of everything being broken?
Are there any signs like smells or what a component looks like to see that it is broken? Everything smells normal except for the PSU.
You really aren't going to know about the other components until it's fired up with a healthy PSU. I've had PSU blowouts in the past that have taken just about everything with it, but conversely I've had PSUs pop that did nothing to the rest of the machine.
Depends on the failure mode of the PSU.Originally Posted by IntaCepta
Pretty crap how if a psu will go down it will take everything down with it

Hello, thanks very much for this.
I have just done this and the fan spins up fine!
What does this mean, what can I do as it is now spinning?
Thanks.
Yeah its broken.
The other thing to check would be the power supply to motherboard connection, is it loose, slightly out of socket? If so, you may have had a short, which burned a fuse in the PSU.
If you have an old power supply connect that to the mobo, remove everything - including processor RAM, etc. If the motherboard beeps at you then it is not fried.
remove the PSU and sniff it, if it is that then its just bad luck and does happen, email support, if its not been in production longer than the warranty as most companies back straight down and offer the repair service.
sorry didnt see the 2nd page so ignore that as you already have it off.
remove all the parts from the PC and inspect for signs of the burning, if its an add on card you can remove it to test, but no life on the motherboard and a PSU thats jsut spun up doesnt look good for the motherboard.
look for blown caps around the CPU socket

Oh ****,
I just tried connecting the PSU back up, I switched it on and everything started spinning like normal, next thing I know I have visible sparks of burning metal coming out!!
I "think" they were from the graphics card but it could have been from underneath it on the motherboard. There were orange sparks which drifted slowly down and alot of smoke.
This is definately not good. So is it the PSU, motherboard or graphics card?
The PSU does spin fine now.
I'm in deep ****.
Well if there's sparks then something is going to be scorched in there, take everything out and inspect for burn marks.
Ok, I have done that but have found no severe burning marks, why do you think that it made something spark? If a PSU is broken, will it break other components or do you think that the PSU is now fine but the graphics was going to spark anyway?
Do you think I should try connecting the PSU backup to the PC again?
Christ no, I wouldnt let that PSU anywhere near my system and just pray that its not broken anything of high value in there. I'd either replace it or RMA it, if you bought it online you don't need the reciept, you can usually log in to your account and print off the old invoice anyway.
I'd get someone who knows what they're doing with a multimeter to give a good going over.
Why did you do that? There is vast experince and knowledge on these boards and they all say that the PSU is dead, like the Monty Python parrot sketch. So why did you try it again? You only have yourself to blame if now every component in your entire rig is borked.
A PSU failure took out my brother's entire rig and he has learnt his lesson so have you.
When something like this happens it's 99 times out of 100 that the PSU is dead. Therefore, don't use that PSU because it will cause further problems. What you must do is take the PC apart and inspect for damage as suggested above. If you find no damage then rebuild the PC with the minimum amount of hardware BUT USE A NEW PSU.
I really hope that you haven't lost your entire rig and the data that's on it.
THROW THE BORKED PSU AWAY NOW!

Hi,
Just a quick note - you do not need the receipt in order to request an RMA.
laze.

man i hope your rigs alright after that
Dont use the psu at all.
Its now a process of elimination, replace rma psu. Rig that up if it still not booting then I would seriously consider saving your pennies for a new system.
The psu could have blown the cpu graphics mobo, that is seemingly more likely from the smoke and orange sparks. I wouldnt risk using any of those components again but maybe i am being over cautious.
