NShi 1800W ATX Mining Power Supply Black server chassis

SKU CH-SRV3-765EB

An 1800W ATX power supply with Active PFC, 140mm dual ball-bearing fan, and connectors for eight graphics cards

  • Chassis styleDesktop
  • 1800W rated output powers up to eight graphics cards
  • 2000W peak capacity handles sudden load spikes
  • 140mm dual ball-bearing fan moves air quietly
  • Active PFC plus 95% efficiency cuts waste heat
  • Full protection suite guards against over-voltage, over-current and short-circuits

1800W Mining Power Supply

This NShi ATX power supply delivers a rated 1800W with a 2000W maximum for cryptocurrency mining rigs. It supports up to eight graphics cards through twelve 6+2-pin connectors. Active PFC and 95 percent efficiency provide stable output across 180-265V AC input. The unit fits a desktop chassis measuring 15 x 14 x 86cm.

18 Copper Output Lines

Eighteen copper output lines supply a 20+4-pin motherboard connector, one 4+4-pin CPU connector, eight SATA, four 4-pin peripheral and twelve 6+2-pin GPU leads. This replaces lower-wattage units that cannot feed eight cards simultaneously. The jump is worth it when a build demands sustained multi-GPU power without voltage droop.

140mm Dual Ball Bearing Fan

A 140mm dual ball bearing fan moves high airflow at low noise during continuous 24/7 mining loads. EMC shielding on the copper wires and full protection circuits guard against over-voltage, over-current, overload, under-voltage and short circuits. Efficiency holds steady under sustained thermal stress rather than only in short bursts.

Questions about this item

What clearance does the 140 mm dual ball-bearing fan need for airflow in a desktop chassis?

The unit measures 15 x 14 x 86 cm; allow at least a few centimetres in front and behind the fan for intake and exhaust.

Which connectors must be populated first when wiring eight graphics cards with the 16 × (6+2) PCIe leads?

Attach the motherboard 20+4 pin and CPU 4+4 pin cables, then connect each GPU with its own (6+2) lead; avoid daisy-chaining.

When should the 140 mm dual ball-bearing fan be cleaned or replaced to maintain near-silent operation?

Inspect the fan every six to twelve months; clean dust buildup and replace the fan if bearing noise appears.
