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.

Questions about this item

What does the 550W rating mean for a typical desktop build?

The unit can deliver up to 550W of continuous power, with 41A available on the 12V rail and 16A each on the 3.3V and 5V rails, supporting mid-range CPUs and graphics cards.

How does the 80 PLUS Bronze certification and ATX 12V 2.52 standard affect efficiency and compatibility?

Certification guarantees over 87% efficiency at typical loads, while the ATX 12V 2.52 design ensures correct voltage regulation and PG signalling for modern motherboards.

Will the 150mm long non-modular chassis with a 120mm HDB fan fit my case and mounting points?

The supply measures 140mm wide, 150mm deep and 86mm high, uses a single 120mm hydraulic-bearing fan, and includes standard ATX mounting screws for typical case bays.
