  • 22 connectors (16 x 8-pin, 6 x 6-pin) support many GPUs

High-capacity mining power supply

This 3300W unit is built for Ethereum miner machines that demand dense 12V delivery. It operates on 180V-264V input and ships with ten replaceable cables providing 22 connectors, including sixteen 8-pin (6+2) and six 6-pin plugs. The all-copper wiring supports multiple protection circuits for over-current, over-voltage, short-circuit, overload and lightning events.

Thermal and electrical profile

A 60mm fan spinning at 15000 RPM drives airflow through the 2U chassis to manage heat at sustained load. Efficiency exceeds 80 percent, so waste heat stays proportionate to the 3300W rating. The supplier notes that builders should reserve 300-400W for the motherboard and ancillary cables when calculating total GPU consumption.

Build practicality

The desktop-form chassis measures 27cm by 11cm and uses a standard 2U height for rack or shelf mounting. Removable cables let technicians swap damaged leads or re-route looms without desoldering. The included power cord and full connector complement mean the unit is ready for immediate integration into a mining rig.

Questions about this item

How do I install this 3300W PSU into a 2U rack chassis and what cable step is often missed?

Mount the 27cm by 11cm unit in the 2U bay, connect the supplied power cord to a 180V-264V source, then attach only the 86+2Pin and 6Pin cables your GPUs actually need; the common mistake is leaving unused cables connected inside the chassis.

Which parts of this mining PSU will need replacement after extended 15000 RPM operation?

The 60mm fan spinning at 15000 RPM is the primary wear item; the 10 all-copper connecting cables and 22 connectors (16 eight-pin and 6 six-pin) are rated for the full 3300W load and typically outlast the fan.

What is the first limit reached when this PSU runs continuously at high load?

Thermal limit appears first; the 15000 RPM fan must move enough air to keep the 3300W output above 80 % efficiency, so restricted intake or exhaust will throttle the unit before electrical protections activate.
