The PSU is about 6 years old but it has never been under stress. I have it powering a CORE I3 with 4GB DDR3 memory and no GPU (using integrated video card). I new it was a bit overkill for the system I have now but it was my first build and it was a really good deal for it at the time. I bought everything with the plans of upgrading at the time but never did and now I was worried it would be no good.
