1000W ATX 3.1 Power Supply

The MSI MAG A1000PLS PCIE5 delivers 1000 watts of continuous power with 80 PLUS Platinum efficiency up to 92 percent. It follows the ATX 3.1 and PCIe 5.1 specifications and uses a single +12V rail design. A 135 mm fluid-dynamic bearing fan provides cooling inside a compact 150 mm long chassis.

Native 12V-2x6 Connector For Modern GPUs

This unit includes a native 12V-2x6 connector rated for 600W, making it suitable for PCIe 5.1 graphics cards such as RTX 50 series models. Builders using older GPUs with standard 6+2 pin connectors are also covered by four additional PCIe plugs. Systems without a 12V-2x6 device will not use the dedicated high-power cable.

GPU Safeguard Monitoring And Embossed Cables

GPU Safeguard monitors the 12V-2x6 connector for abnormal current and sounds a buzzer alert when an issue is detected. The package supplies fully modular embossed jacket cables: one ATX 20+4 pin, two EPS 4+4 pin, one PCIe 5.1, three PCIe, two SATA and one peripheral cable.

Questions about this item

What motherboard connector does the PSU need to power the board?

The unit supplies a 20+4 pin ATX connector that plugs directly into the motherboard main power socket.

Can I keep using my existing SATA drives and older PCIe graphics cards with this supply?

Yes, the box includes six SATA power leads and four 6+2 pin PCIe cables alongside the new 12V-2x6 connector.

How do I know the 12V-2x6 connection to my GPU is seated correctly?

The native 16-pin cable has yellow highlights that make a loose fit easy to spot, and GPU Safeguard sounds a buzzer alert if current becomes abnormal.
