Cooler Master's Real Power Pro RS-550-ACAA-A1 PSU is designed with the power user in mind. This 80 Plus certified unit has a rated continuous output capacity of 550W with a max peak output of 660W. Not only is it a SLI certified unit, it is also compliant with ATX 12V v2.3 and EPS 12V v2.91.

The 24-pin motherboard connector is backed up by both a 4-pin and an 8-pin CPU connector. There are 5 Molex and 6 SATA connectors for drives and other peripherals. The 2 PCIe connectors have bead core protection to minimize EMI and electrical noise. A floppy drive connector is included, just in case you need one.

Keeping everything cools is a 120mm fan with an automatic speed control. The back panel is a honeycomb mesh for unrestricted air flow. The combination results in a low noise rating of only 17dBA.
