Antec Signature SG650 650W Continuous Power ATX12V / EPS12V SLI Certified CrossFire Ready 80 PLUS BRONZE Certified Modular Active PFC "compatible with Core i7/Core i5" Power Supply

Antec's Signature Series SG650 power supply takes their passion for quality to the next level. The engineers have designed in details that maximize efficiency. Magnetic amplifiers have been replaced with voltage regulators for the 3.3V and 5V outputs reducing transient response time down to 10 microseconds. The faster response ensures a smoother power flow to your system.

The 80mm fan is regulated with Pulse Width Modulation so it can reduce speed by up to 50%. The dual double layer PCB does two things: it allows for a lower component density and increased efficiency. This lets the PSU take advantage of the slower potential fan speeds. It also helps the PSU to achieve an 80-Plus Bronze efficiency rating.

A hybrid system gives you the best of both worlds in cable management. Mandatory cables, like those going to the motherboard, are hard-wired for minimal resistance, and to save you assembly time. The 2 PCIe cables let you hook up dual video cards to the SLI certified PSU. Peripheral cables can be added at need. Antec has put their signature on the PSU, so you can put yours on the whole system.
