Power rating and graphics-card capacity

This ATX12V power supply delivers a continuous 1800 W with a 2000 W peak rating. The manufacturer states it can run six to eight high-power graphics cards simultaneously. It is built for dense multi-GPU chassis that demand sustained 12 V output.

Who this suits and who should look elsewhere

Builders assembling 8-card mining or compute rigs will find the rated headroom matches their workload. Systems needing only one or two GPUs, or platforms requiring quiet office-grade operation, are not the intended use case for this unit.

Connector count and cable gauge

Eighteen copper output cables provide a 20+4 pin motherboard connector, three IDE connectors, sixteen 6+2 pin PCIe connectors and eight additional drive power connectors. The generous PCIe count directly supports the advertised six-to-eight-card configurations.
