EVGA 500 W1 80+ Continuous PowerCertified Power Supply
If you're looking for the best wattage possible for your money, then this model from EVGA is what you want. The retail price on this one is less than $50, which makes it a terrific bargain for a 500W power supply. Of course, if you're setting up a powerful gaming rig then that probably won't be enough for you but it should work well in a lot of budget-friendly computers. The real issue with this PSU is it only has a basic 80 PLUS rating, not even a Bronze rating. That means it is only certified to be 80 percent efficient which is quite low. However, there are a number of budget PSUs on the market that don't have any 80 PLUS rating, so this is still a better option offering great power at a low price. It includes a 4+4 CPU cable along with two PCIe cables, both of which are 6+2Pin connectors. This model also provides six SATA connections and three 4Pin peripheral cables.
