How alternatives differ from the V3
Thermaltake Toughpower GF3 850W ATX 3.1 PSU
The Thermaltake Toughpower GF3 850W shares the same 80 Plus Gold efficiency and ATX 3.1 standard as the Cooler Master. It uses the same 12V-2x6 PCIe 5.1 connector for modern GPUs. However, it adopts a standard ATX form factor rather than the Cooler Master’s compact size. This makes it slightly shorter at 6.3 inches long, though it is heavier at 3.73 pounds. You should choose this unit if you prefer a standard case layout and do not need the specific compact dimensions of the MWE Gold V3. It provides similar power delivery with a different physical footprint.
Corsair RM1000x Shift 1000W ATX 3.1 PSU
The Corsair RM1000x Shift offers significantly more power at 1000W compared to the 850W Cooler Master. It also features ATX 3.1 support and PCIe 5.1 connectivity. The main difference is its size. This unit is much taller at 5.08 inches high, which may not fit in smaller cases that accommodate the Cooler Master’s compact profile. It weighs 4.2 pounds. You should pick this Corsair model if your system requires higher wattage for future upgrades and your case can handle the larger ATX dimensions. It sacrifices compactness for increased power capacity.
MSI MAG 1000W Gold Modular Power Supply
The MSI MAG 1000W Gold provides 1000W of power, exceeding the Cooler Master’s 850W output. It is fully modular and includes the same ATX 3.1 and PCIe 5.1 specifications.

You should select this MSI power supply if you need maximum wattage for high-end gaming and do not mind a bulkier unit. It trades the compact form factor of the Cooler Master for higher power and a longer warranty period.
Super Flower Leadex VII XG 1000W
The Super Flower Leadex VII XG 1000W delivers 1000W of power with ATX 3.1 and PCIe 5.1 support. It matches the Cooler Master’s compact height of 3.4 inches and similar width. However, it is shorter at 5.9 inches long and weighs 4.5 pounds. This unit is designed for users who need higher wattage without increasing the height of the power supply. You should choose this Super Flower model if your case limits height but allows for a slightly different length. It offers more power while maintaining a relatively small profile.
Super Flower Leadex VII XP PRO 1000W
The Super Flower Leadex VII XP PRO 1000W also provides 1000W of power with ATX 3.1 and PCIe 5.1 compatibility. Like its sibling, it shares the same compact dimensions of 5.9 inches wide and 3.4 inches high. It weighs 4.5 pounds. This unit is ideal for builders who require high wattage but are constrained by case height. You should pick this model over the Cooler Master if you need extra power for demanding components. It maintains a similar physical footprint while delivering greater electrical capacity for your system.
Corsair RM850x 850W ATX 3.1 Power Supply
The Corsair RM850x ATX 3.1 offers the same 850W output and 12V-2x6 connector as the Cooler Master. It differs in form factor, using a standard ATX size that is 5.91 inches high and 2.3 inches long. This unit is significantly longer in width than the compact Cooler Master. It weighs 3.9 pounds.
