Hi,i have in my pc older CM Thunder 600W(older model),on tuesday afternoon i tried some games after windows reinstall and PSU started buzzing and vibrating,i think for 95 % its from PSU,tomorrow i played game if it started,i played for next 10 minutes and then pc shuts down,but it can be normally turned on,it is PSU failure? If it is i want to buy Zalman ZM700-GLX,with 80plus bronze and many connectors as i need.
