1600W Mining Power Supply

This TOPOWER TOP-1600WM1 unit delivers 1600 W for cryptocurrency mining rigs. It supports up to eight graphics cards for coins such as BTC, ETH, LTC and XMR. The single +12 V rail provides 128 A for stable GPU loads. Active PFC handles input from 100 to 240 V at 50 or 60 Hz.

Non-modular ATX Installation

The supply uses a fixed 20+4 pin main connector and sixteen 6+2P PCI-Express leads. Its 165 mm length fits standard ATX mining chassis. A single 135 mm fan cools the unit. Cable routing must account for all sixteen PCIe plugs and eight SATA connectors. Ensure the case has enough depth for the non-modular harness.

Pre-purchase Compatibility Checks

Verify the motherboard accepts a 20+4 pin ATX connector and that the chassis clears 165 mm depth. Confirm the AC supply operates within 100 to 240 V range. Count the required PCIe 6+2P connections for each GPU. Check that the single +12 V rail design matches the rig power distribution plan.

Questions about this item

Will this power supply fit inside a standard ATX mining chassis?

The unit is 165 mm long and uses an ATX 12V form factor, so it fits most standard mining frames that accept ATX supplies.

Can I run eight graphics cards from the native connectors?

Yes, the supply provides sixteen 6+2-pin PCIe connectors, enough for eight dual-connector GPUs without adapters.

What AC voltage range does the unit accept for worldwide use?

The input range is 100 to 240 V at 50 or 60 Hz, so it works on mains power in most countries.
