GAMEMAX PSU Spec Comparison
Form Factor
The GAMEMAX 1050W ATX 3.0 ARGB Power Supply uses a standard ATX form factor. It measures 10.3 inches wide, 5.24 inches high, and 11.4 inches long. This size fits most standard mid-tower and full-tower cases. The GAMEMAX 850W SFX Gold Power Supply uses the compact SFX form factor. SFX units are designed for small form factor builds where space is limited. If you are building in a standard case, the ATX unit offers more flexibility. If you need a smaller footprint, the SFX unit is the better choice.
Wattage
Power output is a key difference between these two models. The GAMEMAX 1050W ATX 3.0 ARGB Power Supply provides 1050 watts of total power. This higher wattage supports very high-end graphics cards and CPUs that draw significant power. The GAMEMAX 850W SFX Gold Power Supply provides 850 watts. While still powerful, this lower output may limit the highest tier of components. You should choose the 1050W unit if you plan to use extreme hardware. The 850W unit is sufficient for high-performance builds that do not require maximum headroom.
Fan Size
Cooling hardware differs significantly between the two units. The GAMEMAX 1050W ATX 3.0 ARGB Power Supply includes a 140mm fan. Larger fans can move more air at lower speeds, which often results in quieter operation under typical loads. The specifications for the GAMEMAX 850W SFX Gold Power Supply mention an FDB fan but do not list the exact diameter. SFX cases often have limited airflow, so fan noise characteristics matter. The larger 140mm fan in the ATX unit generally offers better acoustic performance potential due to its size.
ATX Version
Both power supplies support the latest ATX 3.0 standard. This version includes native support for PCIe 5.0 components. Each unit comes with a 12VHPWR 16-pin connector. This cable can deliver up to 600W directly to modern graphics cards. This feature ensures compatibility with the newest high-performance GPUs without needing adapters. Since both products offer identical ATX 3.0 support and the same PCIe connector type, there is no advantage for either side in this category. Both are ready for future hardware upgrades.
ARGB Lighting
Visual customization is only available on one of these models. The GAMEMAX 1050W ATX 3.0 ARGB Power Supply features addressable RGB lighting. It supports 25 smart lighting modes and syncs with 5V motherboard ARGB software. This allows you to match the PSU color to the rest of your build. The GAMEMAX 850W SFX Gold Power Supply does not list any RGB lighting features in its specifications. If you want visible lighting effects, the 1050W ATX unit is the only option. The 850W SFX unit is a plain white design.
Which PSU fits your build best
