Re: Corsair HX850w blown internal fuse?
Replaced the y caps & repeated the lamp test: Success!
Blew the fuse again, just like Mikay's PSU; have 4 more but it's just going to blow again
Is it worth ripping out the FETs & testing them?

Yes it was wired in series, just not with the rest of the unit attached; will put it all back together when the y caps are replaced & test it then, but still sure those small components are bad

Re: Corsair HX850w blown internal fuse?
If you mean test the y caps by sticking the kettle lead in the PSU socket & attaching a lamp on the other side, then already thought of that
Just did this; the y caps are bad; will order some
Need to get new tips or new iron for those small resistors & cap though...Leave a comment:

OK; took the switch off & during this act the flexed copper / brass inside it clicked back into place; will still need replaced though but now tests good
Notice a couple of small caps after the pwm controller are not letting current through as well as a couple of resistors; will post pics later
Got a TX850V2 for £36 so this will probably be a nothing more than a low priority project now; will probably just sell it for a few quid for spares, or a bit more if it gets working

Haven't removed it yet; the lives are poked through it & heavily soldered (4 terminals) whereas the replacement just has 2...Leave a comment:

Re: Corsair HX850w blown internal fuse?
It's OK Mikay; was keen to try a 12a fuse, but hey-ho
So got the fuse holder on, got the fuse in - still nothing
Discovered that the rocker switch is flaky - another common fault with this model
It is effectively constantly on; there is continuity whatever state it's in & it doesn't switch completely to the off position like it should
Going to try a switch from an older PSU; will post back the outcome
Tested this one for continuity & it isolates...Leave a comment:

Re: Corsair HX850w blown internal fuse?
Yes, suspecting a short somewhere after reading the review on HardOCP with the secondary PCBs; the fuse is gone & the fan tested good, there is, however, a sign of burning on the neutral pin on the kettle lead socket; looks like quite a surge

Got it on eBay, the thing is in sparkling condition; looks like it has been used for only a few weeks

So what happened Mikey? Did it work ok?
Have the exact same issue with a CX750...Leave a comment:
