Mining rig power supply

This 1800 W unit delivers up to 1600 W at 110 V and is built to feed eight graphics cards in a cryptocurrency mining rig. It accepts a wide input range from 100 V to 240 V and uses an AT form factor for compatibility with standard mining frames. The 12 V rail provides the bulk of the power needed for GPU-heavy workloads.

Thermals and noise

A temperature-controlled fan spins only when internal heat exceeds 50 degrees Celsius, ramping speed as temperature rises to keep noise low during lighter loads. The manufacturer claims a 90 % conversion rate, which reduces wasted energy and helps limit heat output under continuous operation. Firm cable seating is essential to avoid short-circuit risk.

Build integration

The unit includes eight SATA connectors and six-pin leads, though four-pin CPU and dual four-pin plugs are not supplied. An unused pin position on the interface is normal because the negative 5 V line has been omitted. Ensure your mining frame can accommodate an AT-style supply and that all GPU power cables match the available connectors.

Questions about this item

How do I install the myVolts Bitcoin Miner 1800w PSU correctly and what is the step most people get wrong?

Connect every cable firmly to the mining machine's port before powering on; a loose link can cause a short circuit and fire risk, which is the step users most often rush.

What maintenance or replacement will this PSU need later?

The temperature-controlled fan only spins above 50 degrees Celsius, so plan to clean dust from the heatsink and verify fan operation periodically to maintain cooling performance.

What limit appears first under sustained heavy load on this unit?

At 110 V input the PSU delivers 1600 watts maximum, so the input-voltage power ceiling is the first constraint you will hit during continuous mining.
