Hey guys,
My computer is getting turned off during light outs instead of having a UPS. Let me tell you my spects.
450w Corsair PSU
gtx 1050ti
8gb ram ddr3
amd fx 8320
gigabyte ga 78lmt usb 3 motherboard
1tb hard disk
My computer runs smoothly during usual time. No problems in that case. But during light outs it gets turned off suddenly instead of having a UPS which is supposed to give me a 5-10 mins of minimum backup.
what should I do? I'm not entirely sure that is it my UPS or any other part for which this thing is happening. Can someone say what is wrong? PLS?
