SFX400 400W power supply

The SFX400 is a compact 400 watt unit with a 20+4 pin main connector, an 8 pin CPU connector and an 8 pin graphics connector. It includes three SATA ports, two D-type connectors and a small four-pin lead. The 450 millimetre main cable suits tight SFX layouts. Active PFC and temperature-controlled cooling complete the package.

Builders fitting a small-form-factor gaming rig

This supply suits builders who need a 400 watt SFX unit with the listed connectors and a short main cable. It is not for systems that require modular cables, a higher rated wattage or a different connector mix. Buyers needing more SATA ports or additional PCIe leads should look elsewhere. The non-modular design also limits cable-routing flexibility.

Fixed cable set simplifies installation

The non-modular loom means every connector is permanently attached, so there are no loose cables to manage inside a cramped chassis. The 450 millimetre main cable reaches the motherboard without excess slack. Three SATA connectors and two D-type plugs cover typical drive and peripheral needs. A single small four-pin connector handles a legacy fan or accessory.

Questions about this item

Which motherboard power connector does the SFX400 require?

The SFX400 uses a 20+4 pin main power connector that fits standard ATX motherboards.

Can the 8-pin GPU connector on this unit power a graphics card that only has a 6-pin socket?

Yes, the GPU connector is an 8-pin (2+6) design so the 6-pin portion can be used alone for older cards.

How do I confirm the SFX400 is delivering power correctly after installation?

The 8 cm temperature-controlled fan will spin up and the system will POST, showing the PSU is operating.
