Today I start up my comp then go living room have my breakfast. Suddenly a loud BAM come from somewhere in my home and my whole house power trips. I reset the power box and try to start my comp but it doesn't start at all. No fan spinning no post no nothing.


Do you think my PSU is dead? PSU is a SeaSonic M12ii 850W PSU
I have no spare PSU to do testing.

If this PSU brings down my other hardware components, how ah? Can I claim from SeaSonic?

Other specs:
i7-2600 @ 4GHz
2x GTX 680 SLI
16GB 1600MHz
2x M4 Raid 0
1TB Caviar Black

Just did the "paperclip" method on kickstarting the PSU with 2 molex case fans. Doesn't work. I think 90% chance PSU dead. Hais must seek help from Corbell liao.

@TS

Suggest that you take a torch light and do a visual inspection of your mobo and gfx cards for visible damage (blown caps, burn marks, melting, etc). Check also the different connectors for burn marks. If you want, you can also shine the light into the PSU and take a peek inside.

Well, if there are no burn marks, there is hope...

In the old days of Pentium 4, I had a (no name) PSU go bang in the same fashion. Luckily, everything else was unaffected, and a replacement PSU solved everything.

If you want you can open up the PSU and look at the fuses.

Since you said your house tripped, that means the PSU drew a lot of current. You can follow the connection from the 'live' wire of the psu and search for the fuse.
Most probably that fuse is the one that caused the bang.

Replace the fuse with the same rating( hopefully it is printed on the circuit board), and test the PSU by shorting the green wire to ground and turn it on.
Hopefully the fuse protected your psu and nothing is dead

I thought SeaSonic is one of the top brands recommended by HWZ peeps together with Corsair and FSP?

I agree that Seasonic and Corsair are reliable brands when it comes to PSU. But if your rig is expensive, I think you should also consider a surge protection. Reliable = low issues, which does not mean no issue.

Anyway, check for any physical burn marks, hopefully none on your hardware. That's the best you can do for now since you don't have a spare PSU to test.

Also, this is just plain unlucky. Not likely you can get a company to replace any damaged parts since it is difficult to pin point who is the error party. Potentially, Singapore Powers may also be liable for this. Who knows.

Opening it up will void the warranty.

Dropby SLS to buy a new PSU. RMA takes time. That's the trouble wth DIY. Distro will want to do extensive testing before replacing it or repairing it. That's why just buy without warranty. Have warranty also so troublesome. I buy most of my stuff from Amazon so long as it's cheaper with at least $10 savings. Most, however, are at least 30 - 40% cheaper.

Take for example:
Silverstone PSU for USD 63. Videopro selling for $118.
Logitech K810 for USD59. SLS selling for $159

These are just 2 examples. There are so many more which are cheaper.

I believe the rest of your PC should be fine.
