Re: Troubleshooting Corsair VS450
I don't have the schematics of the VS450, but I have a slightly flaky CX430 that tuns off suddenly at times.
Is there a Weltrend WTxxxx chip as the supervisory/monitoring IC on the secondary side? If so, begin your measurements there. Check the +5Vsb rail to see if it is in spec. Then recap the bypass cap for the WT chip. Worst case, that chip may have blown and will have to be replaced - it's hard to find, but check at Arunkumar and SJ at Ritchie Street. If you find the replacement IC and it works, then replace all the secondary electrolytics like Teapo, Su'scon, Samxon with Japanese equivalents.
BTW, I'm in Chennai.
