Ruth's sister 350W Flex ATX modular internal power cable

SKU CH-RAY7-649MA

350 W modular Flex ATX power supply with full cable set for small-chassis desktop or server builds

  • 350 W rated output powers compact 1U builds
  • Fully modular cabling keeps small chassis tidy
  • Active PFC improves efficiency across 160-264 V input
  • Two SATA connectors support multiple drives
  • 4+4 pin CPU and 6+2 pin GPU cables included

Compact Flex ATX PSU

This 350 W Flex ATX modular supply fits 1U and small-chassis desktop or server builds. It delivers a rated 300 W with a peak above 400 W from a 150 by 80 by 40 mm frame. Full modular cabling keeps the interior tidy and airflow clear. Active PFC and CE certification support stable operation on 160 to 264 V input.

Modular cable set

The bundle includes a 20+4 pin motherboard lead, a 4-pin to 4+4 pin CPU cable, a 6-pin to 6+2 pin graphics cable and a 4-pin to dual SATA cable. Lengths range from 18 cm to 40 cm plus short extensions. This replaces fixed-cable SFX or TFX units where cable routing space is tight. The jump is worth it when the chassis demands a Flex ATX footprint and full modularity.

300 W continuous headroom

The unit comfortably handles a single mid-range GPU and a modest CPU with two SATA drives. It runs out when a build needs more than two 6+2 pin PCIe connectors or an 8-pin EPS cable for high-wattage processors. Builders who need more storage or a second graphics card should look elsewhere.

Questions about this item

What chassis depth does the 150*80*40 MM power supply need?

The unit measures 150 mm deep, 80 mm wide and 40 mm high, so the chassis must clear at least 150 mm in the PSU bay.

Which modular cables plug into the 14-pin socket on the PSU side?

Connect the 14-pin to 20+4-pin ATX cable (18 cm) first, then attach the 4-pin to 4+4-pin CPU cable (40 cm + 5 cm), the 6-pin to 6+2-pin GPU cable (20 cm + 5 cm) and the 4-pin to dual SATA cable (20 cm + 14 cm) into the remaining modular ports.

When should the 4-pin to dual SATA cable be replaced?

Replace the SATA power cable if the connectors become loose, the insulation cracks or the drive reports intermittent power loss.
