GIGABYTE B-GIGABYTE GP-P1000GM 1000 W power supply

1000 W ATX 12V v2.31 power supply

The GIGABYTE GP-P1000GM delivers 1000 W of continuous power through an ATX 12V v2.31 design. Full modular cabling lets you connect only the leads your build requires. 80 PLUS Gold certification confirms 90 percent efficiency at typical load, reducing waste heat and electricity cost. A 12 cm HYB smart fan and Japanese 105 °C main capacitor support quiet, reliable operation across 100–240 V input.

Suited for high-output single-GPU systems.

Builders assembling a high-performance workstation or enthusiast desktop with a single power-hungry graphics card will appreciate the strong +12 V delivery and clean cable routing. The unit lacks the connector count and combined rail current needed for dual or triple GPU configurations. Systems that require redundant power supplies or server-grade monitoring features should look at a different form factor.

80 PLUS Gold efficiency at 90 percent typical load

The Gold rating means the supply converts at least 90 percent of AC input to DC output at 50 percent load, lowering running costs and case temperatures. This single metric is the clearest indicator of whether the unit matches your efficiency targets and thermal budget.
