Thermaltake Toughpower GF 550W 80 Plus Gold Modular Power Supply

What this power supply is

A 550 W power supply, rated 80+ Gold, fully modular.

Efficiency

80+ Gold means about 90% of the power from the wall reaches your parts at half load; the rest becomes heat. Higher ratings run cooler and cost a little less to run.

Cables

Every cable unplugs, so you only fit the ones you need: the tidiest build.

Rule of thumb

Pick a supply that runs at about half to two-thirds of its rating in games: quieter, cooler and room to upgrade.
