1000 W ATX 3.0 power supply

The MSI MPG A1000G PCIE5 delivers 1000 W through a single +12 V rail and meets the ATX 3.0 and PCIe 5.0 specifications. It includes a 16-pin 12VHPWR cable alongside six 6+2-pin PCIe connectors and twelve SATA power connectors. A 135 mm fluid-dynamic-bearing fan runs with a 0 RPM mode at low load, and the unit carries 80 PLUS Gold certification with Cybenetics Standard++ noise rating.

Suitable for high-end GPU builds.

This unit suits builders pairing a 4080 or 4090 graphics card with a modern motherboard that needs the 12VHPWR connection. The 150 mm depth and full-modular flat cables help cable management in standard ATX towers. Systems limited to shorter PSU bays or builds that do not require the new 16-pin interface should consider a smaller or older-specification unit.

12VHPWR connector decides compatibility

The defining specification is the native 16-pin 12VHPWR cable, which allows direct power delivery to PCIe 5.0 graphics cards without an adapter. If the target GPU uses only traditional 6+2-pin connectors, the 12VHPWR cable will remain unused and a different PSU may be more cost-effective.

Questions about this item

Will the 150 mm length and 135 mm fan fit my ATX case?

The unit is 150 mm long with a single 135 mm fluid dynamic bearing fan; measure your case clearance for both length and fan height before ordering.

Which cables must I plug in during installation, and which step is often missed?

Connect the 24 pin main cable, the 16 pin PCIe 5.0 cable for the GPU, and only the modular cables your build needs; the step most often missed is seating the 16 pin connector fully until it clicks.

How long should the 100 % Japanese electrolytic capacitors last under load?

The 100 % Japanese electrolytic capacitors are rated for long life at high temperature; expect many years of continuous operation before any replacement is needed.
