Hello guys i got Corsair CX750M power supply for my FX-8350, GTX960 system. I use this system for 1 years but i got some problems nowadays. Yesterday i cleaned my computer case as i always do, and then when i was in game my computer shut down without any problem message. When i was tried to power on 2-3 minutes later it power on but 1-2 minutes later it shut down again. I looked my PSU, it really hot and when i was power on my pc, psu's fan runs very fast and noisy. What can i do about my psu. I cant buy new PSU because Steam Sales are coming.

Before you can repair this one, you need to identify exactly what - if anything - is wrong with it. Replacing all the output caps may not necessarily help you much if the core issue is some 1-100uF caps on the primary side.

Your PC requires maybe 300W, even a decent quality 500-550W should be more than good enough unless you plan to attempt extreme overclocks or upgrade to a GTX1080 and overclock that.

A low quality PSU with 2-3X the required rating is no substitute for a high quality PSU with a 30-50% margin. Once the true power requirements are met, quality becomes far more important than quantity, as you may have discovered with the CX750.
