300 W SFX power supply for small chassis

This 300 W SFX unit fits Mini-ITX and all-in-one cases where space is tight. It targets builders of compact desktops, HTPCs or point-of-sale machines that need a standard SFX footprint. The non-modular design keeps cable routing simple in very small enclosures. It delivers 300 W across the 165–265 V input range.

20+4 pin ATX and fixed cable limits

The 20+4 pin motherboard connector, a 4-pin CPU plug, two 6-pin PCIe leads, three SATA and three D-type plugs are all permanently attached. You cannot remove unused cables, so plan routing before installation. The 300 W ceiling and two 6-pin PCIe connectors restrict graphics choices to lower-power cards. Active PFC helps maintain efficiency across the input voltage span.

Non-modular build with dense connector cluster

All leads exit the housing together, creating a thick bundle that must be folded behind the motherboard tray in tight SFX bays. The fixed 4-pin CPU connector reaches most Mini-ITX sockets without extension. Three SATA ports serve a typical compact drive complement. No 80 PLUS badge is present, so efficiency sits at the basic certification level only.

Questions about this item

Should I pick the 300W SFX unit or a different wattage for my Mini ITX build?

The 300W rating suits low-power Mini ITX systems such as all-in-one PCs or cash registers; choose a higher wattage only if your components demand more headroom.

What does the 300W rating actually deliver inside my case?

It supplies up to 300W total through a non-modular design with a 20+4 pin motherboard connector, a 4 pin CPU connector, two 6 pin GPU connectors and three SATA power plugs.

How does the 20+4 pin interface limit what I can connect?

The fixed 20+4 pin ATX connector powers standard motherboards, while the two 6 pin GPU plugs and three SATA ports cap graphics and drive support to those exact counts.
