myVolts 1800W AT Power Supply 220V Active PFC 8 GPU

SKU CH-VBP9-2SPTX

An 1800 W AT power supply with active PFC, 90% conversion efficiency and 110–265 V input range, supporting eight graphics cards via 16 PCIe connectors

  • TypeAT
  • Stable 110-265V operation with active PFC
  • 90%+ conversion efficiency saves energy
  • Reliable 1800W output for 8 graphics cards
  • Consistent voltage protects motherboard and drives
  • Modular all-copper cables with 16 GPU connectors

AT power supply for mining rigs

This AT-type power supply delivers 1800 W of rated output and is built to feed up to eight graphics cards in a mining machine. Active power-factor correction keeps the input range wide, letting the unit run on 220 V single-voltage lines between 180 V and 265 V or on a full-voltage span from 110 V to 265 V. The design targets builders who need dense multi-GPU power in a single chassis.

Check motherboard power connectors before ordering

The unit provides a 20+4-pin motherboard connector and a 4+4-pin CPU connector, so verify that your board accepts these pin counts. Sixteen independent 6+2-pin GPU leads are included, alongside eight SATA drive connectors and three IDE fan headers. All output cables use copper conductors and are supplied in longer lengths for flexible routing inside large frames.

Active PFC maintains stable rails under continuous

Conversion efficiency reaches 90 % or higher, far above the typical 70 % seen with passive PFC designs, so waste heat stays lower during round-the-clock operation. The active circuit holds output voltage steady even when mains voltage drifts across the 180–265 V window, protecting motherboards, drives and GPUs from the sags and spikes common on rural or industrial feeds. Not suited for builds that require fewer than eight GPU connectors or standard ATX form-factor mounting.

Questions about this item

What cables and connectors come with the 1800W AT unit, and is anything else needed to run eight graphics cards?

The supply ships with a 20+4-pin motherboard connector, a 4+4-pin CPU connector, sixteen 6+2-pin graphics connectors, eight SATA connectors and three IDE fan connectors. All output leads are copper and described as long. No extra cables are required for eight GPUs.

Should I choose the 110V full-voltage (110-265V) or the 220V single-voltage (180-265V) version for my mains supply?

Select the 110V full-voltage model if your local mains can dip below 180V; it operates from 110V to 265V. Choose the 220V single-voltage model only where the supply stays between 180V and 265V.

What does the 1800W rating mean when the power supply is installed in a mining rig with eight GPUs?

1800W is the maximum continuous DC output the unit can deliver across all rails. With active PFC efficiency of 90% or higher, it supplies stable power to eight graphics cards, motherboard, CPU and drives while drawing less AC power than a passive-PFC design.
