Compact SFX power for small builds

The APEVIA SFX-AP400W is a 400 W SFX power supply built for Mini-ITX and Micro-ATX systems where space is limited. It delivers steady output through a single 80 mm thermally controlled fan and fully sleeved cables to keep tight interiors tidy.

Fits small-form-factor upgrades.

This unit suits builders replacing a failing SFX unit or assembling a compact office or home-theatre PC with modest power needs. It is not for systems that require multiple PCIe power connectors or sustained loads beyond the rated 400 W output.

One 6/8-pin PCIe connector limits graphics choice

The power supply provides a single 6/8-pin PCIe connector alongside a 20+4-pin main, a 4-pin 12 V (P4), two SATA, two 4-pin Molex and one 4-pin floppy connector. That lone PCIe lead means only graphics cards with a single 6-pin or 8-pin input can be powered directly.

Questions about this item

How loud is the 80mm thermal-sensing fan under continuous load?

The 80mm fan adjusts speed automatically based on temperature, so it stays quieter during light work and ramps up only when the unit needs more cooling.

Which motherboard power connectors does the SFX-AP400W include for a Mini-ITX build?

It provides a 20+4-pin main connector and a 4-pin 12 V (P4) connector, covering standard Mini-ITX and Micro-ATX boards.

Can I keep my older IDE drives when using this PSU?

The unit offers two SATA connectors, two 4-pin Molex connectors and one 4-pin floppy connector, so legacy drives with Molex or floppy power will still work.
