SFX 650W Bronze PSU

The Ruth's sister SFX650W is a fully modular power supply built for compact desktop and server builds. It fits SFX-compatible mini-ITX cases and delivers 80 PLUS Bronze certified efficiency. Active power factor correction handles input voltages from 90 to 264 volts. The unit ships new and ready for integration.

650W output with 18A rail

The supply provides a 650 watt rating and an 18 amp output on the main rail. Four SATA ports support multiple drives while two 6-pin PCIe connectors feed a graphics card. A 4-pin CPU connector and 20+4 pin motherboard interface cover core components. Headroom suits mid-range gaming systems; high-end multi-GPU configurations will exceed the available connectors and wattage.

Fully modular SFX construction

Full modularity lets you attach only the cables required, reducing clutter in tight chassis. The SFX form factor matches small-form-factor mounting points. Connectors include two D-type bus interfaces alongside the standard ATX and peripheral plugs. Build quality targets reliable operation in space-constrained desktop and server environments.

How can I verify the 80 PLUS Bronze efficiency is active after installation?

The PSU delivers up to 650 W output with active PFC across 90-264 V input; stable voltages under load confirm the Bronze-rated efficiency is functioning.

Which cables are included and must I buy extra SATA or PCIe leads?

The modular unit includes cables for the 4-pin CPU, 20+4-pin ATX, two 6-pin PCIe and four SATA ports; no extra leads are required for those devices.
