I had my PC custom built 3 years ago. It had an NSpire 750W power supply. That power supply died recently so I got an Antec True Power New 750W (Antec True Power New 750W). When I installed it the computer shut down after 5 minutes. Thinking it was a bad power supply I replaced it with an OCZ ModXstream Pro 600W (OCZ ModXstream Pro 600W). Now the computer shut down after an hour or two. I ran my motherboard's monitoring software and saw that the CPU was overheating. I decided to reset my motherboard bios (the builder had done some mild overclocking) and the CPU overheating problem is now fixed (CPU temperature between 34-41 C for 24 hrs).
So I currently have the OCZ 600W PS and everything runs great. But I am concerned because the builder used a 750W power supply originally. I have also used several online power supply calculators and the recommended wattage is right around 600W or a little above it. So I'm wondering if I should go back to the Antec True Power New 750W or leave things as they are?
