Rectangular silver server PSU with modular cable sockets and cooling fan grille

T.F.SKYWINDINTL

T.F.SKYWINDINTL 1800W server power supply 110V-220V

SKU CH-0AF4-AW1KK

Fully modular 1800W server PSU with dual CPU connectors, six PCIe cables and four SATA cables for multi-GPU mining rigs

  • Maximum Power1800W
  • 1800W output powers dense multi-GPU mining rigs
  • Fully modular cabling keeps builds clean and airflow unobstructed
  • Dual 8-pin CPU connectors support server-grade motherboards
  • 85% efficiency at 110V cuts waste heat under load
  • Wide 90-264V input range works on global mains power

Purpose-built mining and multi-GPU power

This 1800W server-grade supply targets miners running rigs such as S7, S9, L3+ or D3 units and builders who need to drive up to six graphics cards. The fully modular cable set keeps the chassis tidy and simplifies upgrades. It is not suited for compact cases or silent workstations that demand low acoustic output.

Modular cabling and dual-install flexibility

A 20+4 pin motherboard lead measuring 55 cm, four SATA strings at 55+15 cm, one triple IDE chain at 50+15+15 cm, six 6+2 pin PCIe leads at 50+15 cm and two 4+4 pin CPU cables at 50 cm cover diverse builds. The two-way mounting design fits both standard PC cases and open mining frames, while a 24-pin bridge is required to start the unit without a motherboard connection. Each PCIe cable is rated for 250W maximum load.

High-flow cooling and wide voltage range

High-flow fans move large air volumes to dissipate heat from the 1800W load, so audible noise is noticeable during operation. Efficiency reaches 85% or higher at semi-loads across a 90-264V input range, delivering stable output on 110V and 220V mains alike.

Questions about this item

What voltage range does the 1800W unit accept, and what efficiency can it reach?

It operates from 90V to 264V and reaches 85% efficiency or higher under semi-loads.

What connector lengths must fit inside my case or mining frame?

Cables include 24Pin at 55cm, SATA chains at 55+15cm, IDE chains at 50+15+15cm, PCIe 6+2pin pairs at 50+15cm, and CPU 4+4pin at 50cm.

Why does the supply not start when plugged into a motherboard, and how do I fix it?

Without a 24Pin motherboard connector you must insert the 24Pin bridge into the 24Pin power cord port so the unit can start.
