Pros & Cons

Pros

  • ✓ Native 12VHPWR 16-pin delivers up to 600W to one GPU, no adapter
  • ✓ Handles 3x GPU and 2x total power excursion for transient spikes
  • ✓ 80 Plus Gold certified: 90%+ efficiency, less waste heat
  • ✓ DC-DC plus LLC resonance and 12V synchronous rectification for rail stability
  • ✓ 140mm hydraulic-bearing fan stays quiet under sustained load

Cons

  • ✗ ARGB sync requires a compatible motherboard header and vendor software
  • ✗ 1050W is overkill for mid-range builds drawing under 500W
  • ✗ Lighting adds visual noise in builds with a non-windowed case
  • ✗ Gold, not Platinum or Titanium, so top-tier efficiency is left on the table

Manufacturer description

The GAMEMAX RGB-1050 is a 1050W fully modular ATX 3.0 power supply built for the 12VHPWR era. Its native 16-pin connector delivers up to 600W to a single graphics card, so you can drive a current-generation GPU without daisy-chaining adapters. Because the unit is rated for 2x total power excursion and 3x GPU power excursion, the transient spikes that trip lesser supplies during a shader-heavy load are handled in stride. Internally, GAMEMAX pairs a DC-DC topology with LLC resonance and 12V synchronous rectification to hold rails steady under swing, and the 80 Plus Gold certification means 90%…

Frequently Asked Questions

Will this power supply run an RTX 5090 or other 600W graphics card?

Yes. The RGB-1050 ships with a native 12VHPWR 16-pin connector rated to deliver up to 600W to a single graphics card, and its ATX 3.0 / PCIe 5.0 design sustains 3x GPU power excursion for transient spikes.

Is the GAMEMAX RGB-1050 fully modular?

Yes, it is a fully modular ATX unit, so you connect only the cables your build needs and leave the rest out of the case for cleaner routing and better airflow.

How efficient is this 1050W unit?

It carries 80 Plus Gold certification, which GAMEMAX rates at 90% or higher efficiency. Higher efficiency means less of the wall draw is lost as heat inside the chassis.

Does the RGB sync with my motherboard lighting?

The addressable RGB syncs with motherboard ARGB software and offers 25 lighting modes with an RGB memory function that retains your selected mode. Confirm your board has a standard ARGB header before buying.

How loud is the fan under load?

The unit uses a 140mm fan on a hydraulic bearing, which GAMEMAX specifies as whisper-quiet while maintaining heat dissipation. Larger fans move the same air at lower RPM than the 120mm units common in this wattage class.
