Ruth's sister SFX 500W 80 PLUS internal power cable

SKU CH-RVZP-9CPY3

SFX form-factor 500 W unit with full modular cabling, 80 PLUS efficiency and active PFC for compact desktop or server builds

  • SFX form factor fits compact Mini ITX builds
  • 500 W rated power with 750 W peak for demanding components
  • 80 PLUS certification at 85 % efficiency reduces waste heat
  • Active PFC across 94 V–264 V input ensures stable delivery
  • Full modular cabling with four SATA and two 6-pin connectors

Compact SFX power supply for small-form-factor

This 500 W SFX unit fits Mini ITX and Micro ATX cases where standard ATX units will not install. It delivers 80 PLUS certified efficiency at 85 % and operates on a 90–264 V input range. The fully modular design lets builders connect only the cables their system needs. Active PFC and temperature-controlled PWM fan speed keep output stable and acoustics low.

Fully modular cable set reduces clutter

Included connectors cover an 8-pin CPU power, two 6-pin PCIe graphics plugs, four SATA ports and two D-type bus plugs. A 20+4 pin main motherboard cable completes the kit. Because every lead is detachable, unused cables stay out of the case, simplifying routing in tight chassis. The package ships with all modular cables included.

Steel chassis measures 120 by 100 by 63 mm

The compact enclosure carries CB, CCC, FCC, CE and RoHS certifications. A single fan provides cooling while PWM control adjusts speed to load. Output rails supply 18 A on 3.3 V, 18 A on 5 V, 40 A on the primary 12 V rail and 2.5 A on 5 V standby. Wide-voltage support and active PFC suit both desktop and server deployments.

Questions about this item

Will the 80 PLUS efficiency rating hold up after years of continuous use?

The unit is rated at 85% efficiency under the 80 PLUS standard; efficiency can degrade slightly over time but the certification reflects performance at the tested loads.

What limits output first when the supply runs at full 500 W for hours?

The +12 V rail delivers up to 40 A (480 W), so the 12 V current limit is reached before the overall 500 W rating.

How loud and hot does the single fan get during all-day operation?

The temperature-controlled PWM fan adjusts speed to load, so noise and heat scale with the actual power draw rather than running at a fixed maximum.
