Manufacturer description
The Apevia SFX-AP500W is a 500W SFX power supply for compact builds. It fits Mini ITX and Micro ATX systems where a full-size ATX unit won't. The housing measures 125 x 100 x 63.5 mm (4.9 x 3.94 x 2.5 in), so it suits small cases, and it also works as a replacement for a failing PSU in an older small form factor PC. The connectors cover both current and legacy hardware. The main motherboard plug is a 20+4 pin that splits for older 20-pin boards. The 8-pin CPU lead splits into 4+4 for boards that need only 4 pins, and the PCIe lead splits into 6+2, so you can power a graphics card that takes…

Frequently Asked Questions
Will the Apevia SFX-AP500W fit in my Micro ATX case?
It is an SFX-size unit measuring 125 x 100 x 63.5 mm (4.9 x 3.94 x 2.5 in). It fits cases with an SFX power supply bay. If your case only has a standard ATX bay, check whether it supports SFX mounting or needs an adapter bracket.
Can this power supply run my graphics card?
It has one 6+2 pin PCIe connector, so it can feed a single graphics card that needs one 6-pin or one 8-pin input, within the unit's 500W total output. Cards that need two or more PCIe power leads are not supported.
Does it work with older motherboards that use a 20-pin power connector?
Yes. The 24-pin main connector splits into 20+4, so you can plug just the 20-pin section into older boards. The 8-pin CPU connector also splits into 4+4 for boards that need only a 4-pin CPU plug.
Why won't the power supply turn on when I plug it into the wall?
This is by design. The unit will not power on from the AC cord alone. Connect all the power supply cables to the PC properly, then start it from the case power button.
Can I use it in a retro PC build with a floppy drive?
Yes. Along with 3 SATA plugs, it has a 4-pin floppy connector and 2 4-pin Molex connectors. That covers floppy drives, older IDE hard drives and optical drives in vintage builds.
