Seasonic SSP-450RT 450W 80 PLUS Gold ATX12V v2.3 Power Supply
For a reasonable price, this budget power supply gives you the perfect combination of power and efficiency. It has an 80 PLUS Gold rating, which is pretty much as good as you can find for the cost of this power supply. That means it has a 90 percent efficiency rating and you just won’t find a better option without paying more money. At 450W it may not be the most powerful PSU on the market but the high efficiency rating means you get better performance from it than a more powerful model with no 80 PLUS rating at all. You also get plenty of connections with this model as it includes the main connector along with four SATA connections and two 6+2 PCIe cables. This PSU also has a pair of 4Pin MOLEX cables and a 4+4Pin connector for the CPU.
