Comparing the Alternative Power Supplies
GAMEMAX 1050W ARGB Fully Modular PSU
The GAMEMAX 1050W ARGB provides a higher continuous output of 1050W compared to the 750W MSI MAG A750GL. Both models feature ATX 3.0 support, 80 Plus Gold efficiency, and fully modular cabling. This unit adds addressable RGB lighting, which the MSI model lacks. At 5.91 by 3.35 by 6.61 inches and 3.53 pounds, it is lighter than the 3.97-pound MSI unit. However, it does not detail an LLC full bridge topology or the 120mm fluid dynamic bearing fan found in the MSI supply. You should pick this unit if you need additional wattage headroom for high-draw graphics cards alongside custom lighting effects for your PC chassis.
Apevia Galaxy 1200W Gold ATX 3.0 Power Supply
The Apevia Galaxy delivers 1200W of total power, providing a substantial capacity increase over the 750W MSI MAG A750GL. Like the MSI, it offers ATX 3.0 design, native PCIe 5.0 connectivity, Active PFC, 80 Plus Gold efficiency, and fully modular connections. What you give up is the MSI unit's 120mm fluid dynamic bearing fan and specified LLC full bridge DC-to-DC architecture, which are not detailed for the Apevia. Its dimensions measure 7.5 by 4.5 by 11 inches. You should pick this power supply if you are configuring a high-wattage gaming system that requires extra electrical overhead beyond 750W while retaining full modularity and native PCIe 5.0 hardware compatibility.
GAMEMAX 1050W ATX 3.0 ARGB Power Supply
This GAMEMAX unit expands capacity to 1050W, exceeding the 750W output of the MSI MAG A750GL. It brings a white enclosure, built-in addressable RGB lighting, and an explicit 10-year warranty. Both options share 80 Plus Gold ratings, fully modular designs, and ATX 3.0 standards for PCIe 5.0 graphics cards. What you give up is the MSI's compact dimensions, as this model measures 10.3 by 5.24 by 11.4 inches. You also trade away the MSI model's specified 120mm fluid dynamic bearing fan. Choose this alternative if you are constructing a white-themed gaming rig with RGB synchronization and require higher wattage capacity than a 750W unit supplies.
MSI MAG 850W Fully Modular ATX Power Supply
The MSI MAG 850W updates the power delivery standard to ATX 3.1 and PCIe 5.1 with an included 12V-2x6 connector, whereas the A750GL uses ATX 3.0 and PCIe 5.0. It also provides 850W of continuous output instead of 750W, backed by a 10-year warranty. Both share 80 Plus Gold efficiency and fully modular cabling within the same MSI MAG family. The trade-off is a slightly larger footprint at 8.75 by 4.92 by 12 inches compared to the A750GL. Pick this model if you want an extra 100W of power headroom and prefer the updated ATX 3.1 specifications and 12V-2x6 connector standard for modern gaming hardware.
Corsair RM1000x Shift 1000W Power Supply
The Corsair RM1000x Shift delivers 1000W of Gold-rated power, compared to the 750W MSI MAG A750GL. Both utilize fully modular cabling and ATX 3.0 standards. Its standout difference is the side-facing modular panel, which relocates cable plugs to the side of the chassis rather than the rear. In exchange, the RM1000x Shift weighs 4.2 pounds, slightly heavier than the 3.97-pound MSI, and its side connector layout requires sufficient clearance behind your motherboard tray. It also does not list the MSI's 120mm fluid dynamic bearing fan spec. Select this Corsair unit if you need 1000W capacity and your case supports side-access cable connections for streamlined routing.
NZXT C1000 1000W Gold Fully Modular PSU
The NZXT C1000 provides 1000W of power, offering 250W more output than the 750W MSI MAG A750GL. Both units maintain 80 Plus Gold efficiency and fully modular designs for gaming builds. However, unlike the MSI A750GL, the NZXT C1000 does not list ATX 3.0 compliance or a native PCIe 5.0 connector, relying instead on standard PCIe cables. It is also significantly heavier at 7.47 pounds compared to the 3.97-pound MSI unit. Choose the NZXT C1000 if your build demands 1000W of continuous power and relies on conventional PCIe power connections rather than the native PCIe 5.0 connector featured on the MSI power supply.
