Borrowing the thread for my problem.

I just exploded my PSU again yesterday night. The PSU is about 1 year 8 months old, currently I am looking for a new PSU and I have my eyes on the AeroCool Templarius Imperator 750W from a local shop and the Corsair HX750 and FSP Aurum Gold 750W from Newegg. Need comment on this 2 PSU and recommendation on other PSU.

My old PSU is Xigmatek NRP 700W. My system is running Athlon X4 955, HD7870, 4X4GB Kingston HyperX 1600, 2 HDD, 1 DVD and 2 normal fans + 2 high performance LED fan.

Suspecting the explosion is caused by high power draw from the system. Also please advise the AVR I can use to further protect my PC. I already have an AVR but not sure if it is the correct voltage I need to use.

All the above tells me is that users are screwed anyway because all the factors contributing to a PSU to fail is totally out of the user control. The only way to be sure is to be an electrical engineer and measure everything.

Also the below is on the front page.

Which somehow contradicts the point of "more stress at half output".

PSU calculator calculated my power draw as 463W without any OC at 90% load and 30% cap aging.

That is 66% of a 700W PSU, which I think is reasonable especially when the machine is on at least 6 hrs daily and up to 16 hrs on weekend in a non air conditioned room.

If the argument is true than my OCZ 750W PSU should not last me 6 years while my 700W PSU onlylasy 1 year 8 months.
