Silver 1U rack power supply, 206 by 110 by 62 mm, forced-air cooling, IEC inlet, 12 V output terminals

AFRNDK

AFRNDK APW7 1800W 12V Mining PSU 1U

SKU CH-VA54-HZSR3

A 1U server power supply delivering 12 V at up to 1800 W with 95 % efficiency and automatic over-temperature shutdown

Options APW7 PSU

Struck-through versions exist but are not stocked here.

  • Delivers 1800 W at 220–240 V input for high-density mining rigs
  • 95 % conversion efficiency reduces electricity cost versus 93.5 % designs
  • Automatic shutdown on over-temperature or circuit fault protects attached miners
  • Operates from -20 °C to 60 °C with forced-air cooling at 43 dB
  • Compact 1U form factor measures 206 × 110 × 62 mm and weighs 2.0 kg

High-efficiency DC power supply for ASIC miners

The AFRNDK APW7 delivers a single 12 V DC output rated at 1800 W when fed from a 200-240 V AC source. It is built by Bitmain for crypto mining rigs such as the Antminer S9, Z9, L3++, D9 and T9 series, plus compatible Innosilicon, Ebit and Avalon units. The unit accepts either 100-140 V or 200-240 V AC input and uses forced-air cooling rated at 43 dB.

Voltage-dependent output ceiling

At 110-120 V AC the maximum continuous power drops to 1000 W, so the full 1800 W rating is only available on 220-240 V mains. The power factor reaches 0.99 at full load and conversion efficiency is quoted at 95 percent, compared with 93.5 percent on the older APW3++ design. Over-temperature protection shuts the supply down automatically if internal temperatures exceed safe limits.

150 A headroom at 12 V

The 12.0-12.5 V output can supply up to 150 A continuously on the high-voltage input range, giving ample margin for dense miner configurations. Operating temperature spans -20 °C to 60 °C with 20-90 % non-condensing humidity. The 1U chassis measures 206 × 110 × 62 mm and weighs 2.0 kg. Builds requiring more than 1800 W or a redundant supply architecture will need additional units.

Questions about this item

Will this PSU run on a standard 110 V household circuit?

Yes, it accepts 100–140 V AC, but maximum output is limited to 1000 W at that voltage range.

What efficiency can I expect at 220–240 V input?

The unit delivers 95 % conversion efficiency at full load on 200–240 V AC, compared with 93.5 % on the older APW3++ design.

Does it include protection against overheating?

Built-in overheat protection shuts the supply off automatically if internal temperature rises too high, safeguarding connected miners.
