SKU CH-N1WR-3DV2V

350 W 1U server power supply with ATX 24-pin, two 4-pin CPU, one 8-pin and two Molex connectors

  • 350 W output powers 1U server builds
  • Active PFC corrects input from 100-240 V
  • 24-pin ATX plus 2× SATA connectors included
  • Non-modular design keeps cabling simple in tight chassis
  • 80 PLUS Gold efficiency reduces waste heat

Server-grade 350 W ATX supply

This 1U form-factor PSU delivers 350 W of continuous power for rack-mount servers and compact workstations. It accepts a universal 100-240 V input and uses active PFC to maintain stable output across varying mains conditions. The non-modular cable loom keeps the bill of materials simple for volume deployments.

Steady output under constant demand

Active power-factor correction smooths the input current so the unit runs efficiently during long compute jobs rather than only in brief bursts. An 80 PLUS Gold rating confirms high efficiency at typical server loads, reducing waste heat inside dense chassis. The fixed 24-pin ATX connector ensures a permanent, vibration-resistant link to the motherboard.

1U chassis fit and fixed cable set

The 1U height lets the supply slide into shallow rack enclosures without blocking adjacent bays. Two SATA power headers, two Molex plugs, a 4-pin CPU connector and an 8-pin auxiliary connector cover storage arrays and processor needs in a single loom. No modular sockets means fewer points of failure and simpler cable routing in tight spaces.

Questions about this item

How much power does the PWS-351-1H draw from the wall when running continuously at full load?

The unit delivers 350 W continuous output and accepts 100-240 V input with active PFC; actual wall draw depends on system load and efficiency at that load.

Which motherboard and drive connectors must my system provide for this PSU to function?

It requires a 24-pin ATX socket, a 4-pin CPU power header, two Molex headers and one 8-pin header; the PSU is non-modular so all cables are fixed.

Will the 24-pin ATX and 4-pin CPU connectors on this 1U supply fit a standard desktop motherboard I already own?

Yes, the 24-pin ATX and 4-pin CPU connectors follow the standard ATX pinout and will mate with any compliant desktop board.
