My PC Config : Processor : AMD FX 6100 HDD : WD 1Tb RAM : 4gb Corsair Motherboard : Gigabyte 880GM-d2h GPU : Zotac 560ti Cabinet : Cooler Master 922HAF http://www.coolermaster.in/product.php?product_id=6606 PSU : Corsair GS600 i bought my pc 6 months ago. In Starting i bought Cooler Master 500W PSU. Used it for a month or so it burnt. So, Next time i bought Corsair GS600W and this UPS http://microtekchennai.com/li1000va.html I Thought it was Voltage Fluctuation Problem so bought a UPS. In Starting i had an issue with UPS when ever power failures at my place my pc gets restarted So called MICROTEK Servicecenter he repaired the UPS at this time everything was fine. So, I Started Using My PC with GS600 + UPS. In just 2 days my GS600 Burnt.. and FUSE of the UPS also burnt. It was in warranty so i got it replaced with another GS600 this time i used pc just for 4 hours.. Suddenly my PC Turned off i tried to switch on it again n kaboom PSU burnt again and same FUSE of the UPS also Burnt. So what can be the Problem ? Right now i'm using a 450W PSU without GPU, FANS of my cabinet. USing UPS I'm not facing any prblms now.. so, what can be the problem ?
