  • Delivers 350 W peak output for compact SFX builds
  • Active PFC corrects input from 165-265 V efficiently
  • 20+4-pin ATX plus 4-pin CPU connector fits standard boards
  • Three SATA ports power drives and peripherals directly
  • Dual 6-pin PCIe plugs feed mid-range graphics cards

SFX power supply for ATX cases

This SFX form-factor unit delivers 350 W of rated power with active PFC and a 20 + 4-pin ATX connector. It is built for desktop builders who want to run a compact PSU inside a standard ATX chassis.

Sustained-load behaviour

Active PFC maintains stable input current across the 165-265 V range during continuous operation. The non-modular cable set keeps all leads present, so voltage regulation stays consistent when the CPU 4-pin, dual 6-pin GPU connectors and three SATA drives draw power together.

Compatibility checklist

Verify your case accepts an SFX supply or includes an SFX-to-ATX bracket. Confirm the motherboard uses a 20 + 4-pin main connector and a 4-pin CPU power header. Ensure the graphics card requires two 6-pin connectors and that three SATA power plugs cover your storage devices.

Questions about this item

How much heat and noise does the 350W SFX unit produce under continuous load?

Active PFC and a non-modular design keep efficiency steady, so the fan runs only as fast as the 350 watt load requires.

Which existing cables and connectors must my build already provide for this PSU to work?

The unit needs a 20+4 pin motherboard socket, a 4 pin CPU header, two 6 pin PCIe plugs and three SATA power leads.

Will the 4 pin CPU connector and 6 pin PCIe plugs support an older motherboard and graphics card?

Yes, the 4 pin CPU and dual 6 pin PCIe connectors match legacy boards and GPUs that use those standards.
