Ruth's sister TF350IPSUD 300W 1U 24-pin ATX internal power cable

SKU CH-DGRD-EETSS

Delivers 300 W continuous power in a 1U form factor with full modular cabling and a 24-pin ATX connector

  • 300 W continuous output with 400 W peak headroom for compact servers
  • Full modular design keeps cable clutter out of tight 1U chassis
  • Active PFC corrects input from 160 V to 264 V
  • 24-pin ATX plus 4-pin CPU and dual 6-pin GPU connectors included
  • SATA power lead supplies two drives from a single cable

300W 1U Flex ATX Power Supply

This 300 watt 1U Flex ATX unit fits small form factor servers and ITX desktops. It delivers a rated 300 watts with a peak above 400 watts. The fully modular design uses a 14 pin to 20+4 pin ATX cable that is 18 centimetres long. Active PFC operates on an input range of 90 to 264 volts.

Installation Notes

Full modular cables let you connect only what the build needs. The 20+4 pin motherboard cable is short at 18 centimetres so check routing in deep 1U chassis. CPU power uses a 4 pin to 4+4 pin lead of 40 plus 5 centimetres. Graphics power uses a 6 pin to 6+2 pin lead of 20 plus 5 centimetres. SATA power uses a 4 pin to dual SATA lead of 20 plus 14 centimetres.

Practical Limits

The 300 watt rating limits total system draw so high end discrete cards may exceed capacity. Only two SATA ports are provided for storage drives. The 4 pin CPU connector may not fit boards that require an 8 pin EPS socket without an adapter. Input voltage covers 160 to 264 volts AC for worldwide use.

Questions about this item

How can I verify the 300W 1U PSU is working after installation?

The unit powers on when the 24-pin ATX connector is seated and the 4-pin CPU cable delivers voltage to the motherboard; a POST screen confirms the 300W rated output is active.

Which cables are included and what must I source separately?

The box contains a 14-pin to 20+4-pin ATX cable, a 4-pin to 4+4-pin CPU cable, a 6-pin to 6+2-pin GPU cable, and a 4-pin to dual SATA cable; no extra cables are required for a typical ITX build.

Should I choose the 300W model or a higher-wattage version for my 1U server?

The TF350IPSUD is rated at 300W continuous with a peak above 400W; select it if your total system draw stays under 300W, otherwise look for a higher-rated unit.
