Ruth's sister 350W Small 1U Full Modular PSU internal power cable

SKU CH-Q9MW-DB2WB

A 350 W fully modular flex ATX power supply with active PFC and 80 PLUS certification for small desktop or server chassis

  • Delivers 350 W continuous power for compact desktops
  • Full modular cables reduce clutter inside small chassis
  • Active PFC corrects power factor across 180-264 V input
  • 80 PLUS certification confirms efficient energy conversion
  • Two SATA connectors and dual 6-pin GPU plugs support drives and graphics

Compact 350W Modular PSU for Small Chassis

This 350 watt power supply uses a 1U form factor with full modular cabling to fit small desktop or server cases. Active PFC and 80 PLUS certification support efficient operation from 90 to 264 volt input. Rated output reaches 350 watts with a 400 watt maximum peak. It targets builders who need reliable power in a tight enclosure.

Verify Clearance and Connector Needs Before Buying

Confirm the case accepts a 1U unit and that the 20+4 pin motherboard connector matches your board. The CPU power uses a 4 pin plug, so boards requiring an 8 pin EPS connector will not work. Two 6 pin PCIe connectors limit graphics cards to models drawing power from dual 6 pin inputs. Two SATA ports and two D-type connectors restrict drive and peripheral counts.

Full Modular Build Simplifies Cable Routing

Every cable detaches from the unit, letting you install only the leads required for a clean build in a small chassis. A single fan handles cooling within the compact housing. The fixed 20+4 pin, 4 pin CPU, dual 6 pin PCIe, two SATA and two D-type connectors define the exact device support. Buyers needing more SATA devices, an 8 pin CPU plug or additional PCIe power must choose a different unit.

Questions about this item

What cables come with the 350W full modular PSU and what must I buy separately?

The unit ships with its modular cable set including a 20+4 pin motherboard connector, one 4 pin CPU connector, two 6 pin PCIe connectors, two SATA connectors and two D-type bus connectors; no extra cables are required for a typical small-chassis build.

Which version of the 350W 1U supply should I choose for a flex ATX case?

The single Model Number 350WXH supports the flex ATX form factor, delivers 350 W rated power with a 400 W peak, accepts 90-264 V input and includes active PFC, so there is no alternative version to select.

What does the 350 W rating mean once the PSU is installed in my desktop or server?

It means the supply can continuously deliver 350 W across its rails — up to 20 A on the main output — while meeting 80 PLUS efficiency, and it can briefly sustain 400 W peak loads during demanding tasks.
