Rated power and form factor

This ATX12V 2.52 power supply delivers 550 W of continuous power in a 150 mm long chassis. The non-modular design keeps all cables fixed for simple installation in standard desktop builds.

Intended use and limits

Suitable for mid-range systems with a single graphics card needing one 6-pin and one 6+2-pin connector. Builds requiring fully modular cabling or multiple high-power GPUs should consider a higher-wattage modular unit.

12 V rail capacity

The +12 V rail supplies up to 41 A, providing the bulk of the 550 W for modern CPU and GPU loads. This figure determines whether the unit can sustain your components under full load.
