Ruth's sister 300W 20+4 Pin SFX internal power cable

SKU CH-ZHV6-VTCPY

A 300W SFX power supply with a 20+4 pin ATX connector, active PFC, three SATA ports, dual 6-pin GPU connectors and a 4-pin CPU plug for small-form-factor desktops

  • 20+4 pin ATX connector fits SFX micro-ATX cases
  • 300 W output powers small-form-factor desktop builds
  • Active PFC corrects power factor for efficient operation
  • Three SATA ports supply drives in compact chassis
  • Dual 6-pin PCIe connectors feed discrete graphics cards

What this cable delivers

The Ruth's sister internal power cable provides a 20+4 pin ATX connector rated for 300 W, designed for SFX and micro-ATX power supplies in small-form-factor desktops. It carries active PFC and supports input voltages from 165 V to 265 V. The non-modular design keeps the loom simple for compact builds.

Verify your PSU and board

Confirm that your power supply uses a standard 20+4 pin ATX output and that the motherboard accepts a matching 20+4 pin input. Check that the unit’s 300 W rating matches the PSU label (200 W, 230 W, 250 W, 300 W or 350 W variants exist). Ensure the case has room for the fixed cable routing since the supply is non-modular.

Build and daily handling

The cable assembly is terminated with a 20+4 pin motherboard plug, a 4-pin CPU connector, two 6-pin graphics connectors and three SATA power leads. All wires are sleeved in a single fixed harness, so plan the routing before securing the SFX unit in the chassis. The active PFC circuit reduces harmonic distortion on the mains side.

Questions about this item

Does the cable set include the 20+4 pin ATX connector, CPU 4-pin and SATA cables, or must I buy any separately?

The unit ships with a fixed 20+4 pin ATX connector, a 4-pin CPU plug, two 6-pin graphics connectors and three SATA leads — nothing extra is required.

Should I pick the 200W, 230W, 250W, 300W or 350W version for an SFX Micro ATX build?

This model is the 300W version (model 300wa); choose it when your SFX Micro ATX chassis and components need up to 300 watts.

What does the 300W rating mean once the supply is installed in a desktop running on 165-265V mains?

It can deliver up to 300 watts continuously to the 20+4 pin, CPU, graphics and SATA rails while accepting 165-265V input with active PFC.
