1000W ATX power supply for high-end desktop builds

The MSI MPG A1000G delivers 1000 W of continuous power through a fully modular ATX design. It targets enthusiasts assembling systems with multiple graphics cards or high-current CPUs. A 140 mm fluid-dynamic-bearing fan provides cooling while the unit operates between 47 and 63 Hz input frequency.

80 Plus Gold efficiency limits heat and waste

The supply meets 80 Plus Gold certification, reaching up to 90 percent efficiency at typical loads. Active power-factor correction shapes the input current across the 100 to 240 V range. Protection circuits cover over-current, over-voltage, over-power, over-temperature, short-circuit and under-voltage events. All electrolytic capacitors are rated at 105 degrees Celsius.

Four +12 V rails with 30 A per GPU connector

The +12 V output splits across four rails: motherboard at 25 A, CPU at 25 A and two GPU rails at 30 A each. Four PCIe 6+2 pin cables and two EPS 4+4 pin cables are included. Builders needing more than four PCIe connections or a 12VHPWR native cable should verify compatibility before purchase.

Perguntas sobre este artigo

Should I pick the 1000W version or a lower-wattage model for my build?

Choose 1000W if your graphics card and CPU together draw close to that limit; the four +12V rails each deliver up to 30A for high-end GPUs.

What does the 80 Plus Gold 90% efficiency figure mean once the unit is inside my PC?

At typical loads the supply converts at least 90% of wall power into usable DC, so less waste heat and lower electricity cost.

How does the ATX 24-pin and EPS 4+4-pin layout limit what motherboards I can use?

The 24-pin main connector plus two 4+4-pin CPU cables fit any standard ATX board, including dual-CPU server models.
