High-efficiency 750W AT supply for GPU mining rigs

This AT-type switching power supply delivers up to 750W combined output and is aimed at builders running open-frame GPU mining rigs. It provides a single +12V rail rated at 62.5A plus a 2.5A +12VSB rail, suited to multiple graphics cards drawing heavy current. The unit is fully tested and ships with a breakout board and eight PCIe power cables.

Verify AT compatibility

The supply uses the legacy AT form factor rather than the modern ATX standard, so your motherboard or backplane must accept an AT power connector. Input voltage spans 100V-240V at 50-60Hz, drawing 9.0-4.5A, which matches typical mains worldwide. Each of the eight included 6-pin to 6+2-pin PCIe cables measures approximately 63cm, so confirm that length reaches every card in your open rig layout.

Metal shell with convection cooling and compact

The silver-coloured metal enclosure measures 240 by 85 by 37mm and houses upgraded fans for convection heat dissipation, described as very quiet during operation. A separate breakout board sized 100 by 67 by 17mm carries the output connectors, keeping the main unit slim. Large-capacitor construction is cited for stable performance under continuous mining loads.

Questions about this item

Does the package include every cable I need to connect my graphics cards, or do I have to buy extra PCIe cables?

The box contains the power supply, a breakout board and eight 6-pin to 6+2-pin PCIe cables, so no additional PCIe cables are required for up to eight graphics cards.

Which capacity should I pick if I am building a mining rig with multiple GPUs?

This model delivers a combined 750 W with 62.5 A on the +12 V rail, making it the single capacity available for high-density GPU rigs.

What does the 750 W rating actually give me when the unit is running inside an open mining frame?

The 750 W figure is the total combined output across all rails; the +12 V rail supplies up to 62.5 A and the +12 VSB rail up to 2.5 A, so the unit can sustain that load continuously with the upgraded fans and convection cooling.
