Re: Help with a blow MOSPEC

Thnaks for all your replies! some very helpfull posts here i have had to put the supply on the shelf for a few days becauswe i went and bough a better one on monday (a Skyhawk SH480A8H, dunno how much better but it definatly has much bigger heatsinks) and plugged it in and oh god! my pc wouldnt power on, some quick fiddling revealed that i couldnt power on with either of my hdds plugged in... my damn power supply had grounded through my hdd's!

I was very pissed at this and pulled em out and after a bit of testing managed to figure...

Re: Help with a blow MOSPEC

i apreciate that japlytic, i have allready ordered a new one online at umart i just want to fix this (or try to) to gain better understanding of how it works and then hopefully be able to applythe knowledge to other stuff (car amps for instance)

sooo i have done some more testing and it apears the 3.3V, 5V and 12V lines are the ones affected, they have been left with all the same resistance to ground of 7.2ohms and they have no resistence between them (wheras in the working supply they do), this leads me to believe that something...

Re: Help with a blow MOSPEC

thanks Pete, my mobo is an ASUS A7N8X-X, the PSU is a AGUILER 400W. But now i have gone and done something incredibly stupid and managed to blow something else up, i was adding a heatsink (to the lower one in the pictures) with thermal adhesive cos the one in there looked a little small and got very hot . So all was good till i though "hhmm thats ended up quite close to the live terminal" and grabed the power cord to pull it out and adjust it all and its sliped outta my fingures, bounced back, touched the mains live wire to the heatsink and...

Re: Help with a blow MOSPEC

ack cant edit my previose post hehe, just wanted to add that the 2nd time it blew i only increased the cpu voltage, just seems wierd an increase of only 0.2V to the cpu is causing this component that otherwise seems ok to blow...

Re: Help with a blow MOSPEC

Thanks for your reply! there are no shorts anywhere along the line, the component just failed when i uped the voltages on my memory (2.6->2.8) and cpu (1.65->1.85) to try 220mhz fsb...

I soldered in the 2 10A ones in parallel hoping to make a 20A 40V equivalent (im not sure if that is correnct?) this let me power up with all my things plugged in and seemed to run fine (although at one point, and this was a one-off, i started getting screen corruption/artefacts and restarted, i though this could be related cos i got a radeon 9800xt,...

Hi all, a MOSPEC in my 400W power supply recently failed, it took me 5 hours of testing, unslodering circuits and comparing readings from a 300W PSU with my limited kowledge and experience to figure out it was the 5 volt line and to find the faulty component. the closest match i can find is a mospec from and older 250W AT PSU, Iput it in my 400W one so that i can turn my pc on and get online.

now the one i removed is a S16C40C (16A, 40V) the one i have put in is S15D40C (15A, 40V). i also have available a S10C40C (10A, 40V) and also a SBL1040CT (10A, 40V - I think this is the same...
