I fried my psu?

post #1 of 6
Thread Starter 
Yesterday i wanted to install my newly bought corsair h100i but when i open my case i decided to clean my case so i disassemble everything , clean in and install everything again and when i tried to test boot is yesterday is was smooth sailing. BUT just this morning i attached my monitor mouse keyboard speaker and all those kinda stuff and tried to boot it. when i clicked the power button the fans spun like usual but about 2 sec later i heard a huge "bang" inside my case and realized something shorted but i see no physical burns or anything and can't smell any burns either.

I tried to test my psu by unplugging everything just leaving the case fans attached and did the "paper clip" jumper trick but the psu didn't start. I planned to buy a new psu but i would only if i was sure that my psu is fried. so is there other ways to test my psu?

SPECS:
cpu: i5-2320 @ 3.0GHz 95w
mobo: asus h61p? lxm
gpu: HD7770 80w
hd: WD 500GB blue 7200RPM
3 120mm fans 1 140mm intake
PSU:FSP HEXA 500w @12v 408w (more than enough) - only about 1 year old

note: i tested the rig last night and did work properly but this morning it didn't (i didn't mess with the cables and stuff, only pluged in my monitor, mouse, keyboard, and speakers)

You know it's gone by the paper clip test, so it's funeral time!

Look at the Sub 400w power supplies in this list and get a new one:

Any ideas on why that would happen. I usually don't really care what happen,but now i really want to know why.
I don't believe i did anything to it. It seems so weird.....

Thank you for your reply BTW

FSP isn't a very good power supply manufacturer you probably just over powered it with the h100i even if your not drawing anywhere near what the psu is said to do FSP doesn't make very good psu's i wouldn't recommend using them in the future smile.gif

The question in my mind was that why would it short if i haven't changed anything. plus i tested it first yesterday and seems to boot properly. and yes i don't think i'd touch fsp psu again unless they are free

FSP is actually pretty good, but a lot of their models use bad brands of capacitors, like CapXon. However even bad brand caps normally don't explode but just fail prematurely, like in 2-3 years rather than 5-10 years for high quality brands. OTOH it's possible a cap was dented at the factory, which can cause a short, or installed backward.
