I am using the Corsair AX1200 PSU in my system from the last 6 month, this is the best PSU but however now a days I am dealing with some of the problems with the error there in the Corsair AX1200 that at starting it show 12 volt and then rail to 11.80 volts and then after some of the time it rail to 11.00 volts and not seem to came back to the normal Volts. So I just want to know what this issue is or the error is there in this PSU. Will it harm the system in future or I have to replace this with the new one. So if you guys have any of the information or any of the suggestion for this issue, then please do the reply. Any of the suggestion will be appreciated and thanks.
