Ruth's sister SFX400 400W PSU

This 400 watt mini ATX power supply fits small form factor desktop builds. It delivers a rated output of 400 watts with a peak of 500 watts. The unit uses Active PFC and accepts a universal AC input range. It is intended for builders who need a compact power source for a single graphics card and standard components.

Non-modular cables and SFX dimensions

The supply comes with fixed cables measuring 450 millimetres for the main 24 pin connector. An 8 pin CPU connector, an 8 pin GPU connector, three SATA connectors, two D-type connectors and one small 4 pin connector are included. The non-modular design means unused cables must be tucked away inside the case. Builders with very tight routing space or those needing longer cable runs may find installation awkward.

90 percent efficiency under sustained load

Conversion efficiency reaches up to 90 percent during continuous operation. The 8 centimetre fan supports temperature control to manage airflow as heat builds. Standby power stays below one watt. The unit carries a one year warranty. Systems drawing near the 500 watt peak for extended periods will stress the cooling more than short bursts.

Which version of the SFX400 should I choose for a compact desktop build?
