The EVGA SuperNOVA 550W G2 power supply is a mid-range unit in terms of wattage, but with high-end 80 PLUS Gold rated efficiency and fully modular cabling. It is ideally suited to systems with a single CPU and video card (or onboard graphics). It supports more SATA power connections for drives than previous models we've carried in this size range and it features "ECO mode" which will run the fan at the lowest speed possible to keep the unit cool - fully stopping the fan at low power levels.

William George (Product Development SME) Says:
I've really come to appreciate fully modular power supplies in the last couple of years, and am pleased that even affordable models in our line like this now have that feature. This PSU also has a fan that turns off entirely at low power draw - another feature inherited from higher end models - so it is very quiet and offers enough wattage for most single-GPU systems.
