Ruth's sister 300W 250W SFX ATX internal power cable

SKU CH-V0G2-5TBDE

300W SFX power supply with active PFC, three SATA connectors, two 6-pin GPU plugs and a 20+4-pin motherboard cable for micro-ATX builds

  • Delivers 300 W peak power for compact builds
  • Active PFC corrects input from 165 to 265 V
  • Three SATA ports supply drives and peripherals
  • Dual 6-pin connectors feed graphics cards directly
  • Non-modular 20+4 pin design fits SFX cases

SFX PSU for Micro-ATX builds

This SFX form-factor power supply targets builders assembling compact desktop or server systems that require a small-footprint unit. It delivers a rated 300 W output with a secondary 250 W label for sustained loads. Active PFC helps maintain stable input current across the 165-265 V range. The non-modular cable set keeps installation straightforward in tight chassis.

300 W peak with 250 W continuous headroom

The unit comfortably powers mainstream CPUs and mid-range graphics cards within its 300 W peak envelope. Sustained draws above 250 W reduce available headroom for transient spikes. Three SATA connectors and three D-type connectors support multiple drives and peripherals. Dual 6-pin PCIe plugs feed a single discrete GPU, while the 4-pin CPU connector limits compatibility to boards without an 8-pin EPS requirement.

Non-modular cable layout for compact cases

Fixed cables eliminate modular headers, freeing internal volume in space-constrained Micro-ATX enclosures. The 20+4-pin ATX motherboard connector ensures broad platform fit. Builders must route all leads, including unused SATA or D-type branches, which can challenge cable management in the smallest layouts. The 165-265 V input suits standard mains supplies worldwide.
