How each alternative compares
MSI MPG 850W Gold ATX 3.1 Power Supply
The MSI MPG 850W Gold matches the Enermax in wattage and 80 Plus Gold efficiency. It shares the ATX 3.1 standard and 10-year warranty. The main difference is physical size. This unit is longer at 5.91 inches compared to the Enermax’s 5.51 inches. You need to check your case clearance carefully. It also specifies PCIe 5.1 support for the latest graphics cards. This model suits builders who prioritize compact width in standard ATX cases. If your case accommodates slightly longer units, this provides identical power delivery with a different footprint.
MSI MAG A750GL PCIE5 750W Power Supply
This MSI unit drops to 750 watts, which is 150 watts less than the Enermax. It retains the 80 Plus Gold rating and ATX 3.1 compliance. The form factor is significantly larger, measuring 12 inches in length versus the Enermax’s 5.51 inches. This bulkier design may not fit in smaller cases. It offers a 10-year warranty like the Enermax. You should choose this if you need less wattage for a mid-range build and have ample space in your chassis. The lower power output makes it suitable for systems that do not require the full 850 watts.
MSI MAG 850W Fully Modular Power Supply
The MSI MAG 850W Fully Modular shares the same 850 watts and 80 Plus Gold efficiency as the Enermax. It also supports ATX 3.1 and includes a 10-year warranty. However, it is much larger, measuring 11.5 inches in length compared to the Enermax’s 5.51 inches. This extended length requires a case with sufficient PSU compartment space. It features PCIe 5.1 connectivity for modern GPUs. This option is best for builders with spacious cases who want a standard 850W Gold unit. The larger size may limit compatibility with smaller form factor builds.
MSI MAG 850W Fully Modular ATX Power Supply
This MSI MAG unit offers 850 watts at 80 Plus Gold efficiency, matching the Enermax. It supports ATX 3.1 and comes with a 10-year warranty. The physical dimensions are larger, with a length of 12 inches against the Enermax’s 5.51 inches. It also specifies PCIe 5.1 support for graphics cards. You should pick this if your case can accommodate a longer power supply. It provides the same core performance specs but with a different physical profile. The increased length is the primary trade-off for this alternative, so verify your case compatibility before purchasing.

The Thermaltake unit provides 1050 watts, which is 200 watts more than the Enermax. It maintains the 80 Plus Gold efficiency rating and ATX 3.1 compliance. It includes a 10-year warranty like the Enermax. The size is similar, measuring 5.9 inches in length versus the Enermax’s 5.51 inches.
