Compact silver 1U power supply unit with side fan grille and cable bundle

Ruth's sister

Ruth's sister 1U 350W FLEX HTPC internal power cable

SKU CH-297A-N8AFK

FLEX form-factor 350 W internal power cable delivers up to 500 W peak to ATX 20 + 4Pin motherboards, 8-pin CPU, two 6-pin GPU and multiple SATA drives

  • Compact 1U form factor fits tight HTPC or NAS builds
  • 350 W continuous output with 500 W peak headroom
  • Active PFC plus CB, CCC, FCC, CE, KC certifications
  • 20+4 pin ATX plus 8-pin CPU and dual 6-pin GPU connectors
  • Temperature-controlled PWM fan keeps noise low under load

Compact FLEX power supply for low-profile builds

This 1U 350W unit fits slim desktop, NAS and point-of-sale chassis that need a standard ATX 12V connector set. It delivers up to 500W peak through a non-modular cable harness rated for desktop and server applications.

Active PFC with temperature-controlled fan

The single fan spins under PWM control while active PFC corrects the power factor across a 164-264V input range. Typical loads draw from +12V rails rated at 45A and .3A on the negative rail, with +3.3V and +5V each capable of 15A.

Fixed cables include 20+4 pin ATX.

Three SATA and three IDE connectors serve legacy and current drives, while the 150×140×83 mm frame weighs 1000g. Builders needing more than two 6-pin GPU plugs or modular cabling should look elsewhere.

Questions about this item

How do I connect the 20+4 pin motherboard cable and the 4+4 pin CPU cable in a 1U chassis, and what step is often missed?

Plug the 20+4 pin connector into the motherboard ATX socket and the 4+4 pin connector into the CPU power header; the step often missed is routing both flat cables before sliding the 150 mm deep supply into the 1U bay so they do not kink against the chassis lid.

Which parts of this non-modular supply will need attention or replacement after long-term use?

The single 80 mm fan is the only moving part; its bearings will eventually wear and require cleaning or fan replacement, while the fixed cable loom should be inspected for cracked insulation at the 24-pin, 4+4-pin, 6+2-pin, SATA and 4-pin peripheral connectors.

What limit appears first when the unit runs continuously at high load in a 1U enclosure?

The 350 W continuous rating is reached before the 500 W peak figure; sustained draw above 350 W will trigger protection or cause the fan to run at maximum PWM speed, making thermal headroom the practical ceiling.
