TOPOWER 1800W GPU Mining Power Supply For BTC/BCH/ETC/ETH/LTC/ XMR/XRP/ZEC etc, Ethereum Crypto Coin Mining Miner, Support 8 Graphics Card For ATX Mining Rig, AC Input 100 - 240V

The TOPOWER TOP-1800WM1 is an 1800W ATX/EPS power supply for multi-GPU cryptocurrency mining rigs, with 16 PCIe 6+2-pin connectors and listed support for up to eight graphics cards. It suits builders powering several GPUs from one PSU, provided their rig’s total power needs and connections match the unit.

Recommended For

• Experienced GPU-mining rig builders who need one ATX-format supply with many PCIe connectors for a multi-GPU setup, and who will verify the rig’s actual sustained power draw before use.
• DIY miners assembling or expanding a GPU rig who can work with a non-modular PSU and plan cable routing around its attached leads.
• Technically confident builders comparing high-capacity mining supplies who can independently check load, input-power requirements, and the suitability of their electrical circuit.

Real-World Use Scenarios

• When building an open-frame GPU mining rig, use the PSU to power several cards and the rest of the system from one unit—provided the measured total load and cable connections are suitable. This can avoid coordinating two PSUs, but the advertised GPU count alone does not confirm that every card combination will fit the power budget.
• When expanding an existing mining rig, check the cards’ actual mining power draw and the rest of the system’s load before adding GPUs. If the total remains within the PSU’s usable capacity, the rig may not need another power supply; otherwise, adding cards can cause power-related instability.
• For a mining rig running power-limited or undervolted GPUs, size the PSU around the cards’ configured workload rather than assuming every card will draw its maximum rating continuously. Tuning can reduce power use, but the resulting hash rate depends on the cards and settings.
• When wiring a mining rig that uses separate power supplies, keep each GPU and its riser on the same PSU. This helps avoid splitting power to one card across two units; follow the rig and component makers’ wiring guidance before powering it on.
