SFX power supply for compact builds

This 450W SFX unit fits small-form-factor cases and includes a bracket for standard ATX mounting. It targets builders who need reliable power in limited space without stepping up to a larger chassis. The single +12V rail delivers 36A to support modern components.

Sustained output at 40? ambient

Rated for continuous 450W delivery at 40? around the clock, the supply maintains its full rating during long sessions rather than only in short bursts. 80 Plus Bronze certification means 82% to 85% efficiency across 20% to 100% load, reducing waste heat under sustained demand.

92mm fan and included ATX bracket

The V3.0 revision uses a 92mm fan for quiet airflow at lower speeds. An ATX adapter bracket ships in the box, so the same unit works in both SFX and full-size cases. Builders needing more than 450W or a fully modular cable set will need a different unit.

Questions about this item

How loud does the 92mm fan get under sustained 450W load?

The 92mm fan is described as silent running and the unit is rated for 24/7 operation at 40°C while delivering the full 450W continuous output.

Does the 36A single +12V rail require a specific motherboard connector?

The supply uses standard ATX connectors and includes an SFX-to-ATX bracket so it fits both SFX and ATX cases without extra adapters.

Will the 80 Plus Bronze efficiency hold with a legacy 12V-only GPU?

The 82-85% efficiency range at 20-100% load applies to the single +12V rail design, which is compatible with older graphics cards that draw from the 12V line.
