Indeed they are http://www.overclockers.com/logisys-ps480x2-review I sure as hell wouldn't be risking new components with one of their PSU's, only good thing in that review is it didn't go out with a bang or up in flames. OP I would STRONGLY suggest looking at a good brand PSU, even a budget Corsair or Antec would be better than what you have currently
totally forgot the logisys died after about 4-5 years of use and i now have one of these. http://www.coolermaster.com/product/Detail/powersupply/extreme/extreme-power-plus-500w.html
That will be okay for now but you may need to upgrade that when you go for your GFX card as something like a 670-760-770 require at least a 550W unit 650 W suggested if you plan to overclock. But your good for now.
