Many do not know this but the PSU is the single most important part of your system and anyone who cheap out on a PSU is doing themselfs a bear favor
Brands like Diablotek and Raidmax are the worst carp but almost every brand has one more more crappy PSU models like the old non P Thermaltake TR-2 series
And then there is other things to consider like PSU efficiency
Anyone who want to build a PC sould know at least just a little about PSU´s before they start
Reviews say that this PSU is a quite solid one, although its produced by Solytech which is part of Deer who doesn't have a good reputation. I would say the OP should first upgrade the CPU and if (s)he has money, (s)he should get a new PSU.
