Manufacturer description
The GAMEMAX RGB-1300 is a 1300W ATX 3.0 power supply built for the 12VHPWR era, and it carries the certification to back that headline wattage. Its 80 Plus Platinum rating means 92% or higher efficiency under typical loads, so less of your wall draw turns into waste heat inside the case. The native 16-pin 12VHPWR connector delivers up to 600W to a single graphics card, and GAMEMAX rates the unit to sustain 2x total power excursion and 3x GPU power excursion, which is the headroom modern cards demand during transient spikes. Internally, a DC-DC topology with Full Bridge LLC resonance and 12V…
SpecPicks Verdict
SpecPicks scored GAMEMAX 1300W Power Supply using a rating × review-volume × price-fit model applied to published specs and reviews across the power supplies category. GAMEMAX's power supplies lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.
Common buyer scenarios for power supplies of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase.

Frequently Asked Questions
Does this power supply work with an RTX 4090 or 5090?
It ships with a native 12VHPWR 16-pin connector rated for up to 600W to a single graphics card, which covers current 12VHPWR-based cards. Confirm your specific card's connector and wattage requirement on its spec sheet before buying.
Is 1300W more than I need?
For a single mid-range GPU, yes. The 1300W rating targets high-draw builds: a 600W-class GPU plus a high-core-count CPU, or setups with multiple accelerators. Add up your components' rated draw and leave headroom for transient spikes.
What does 80 Plus Platinum actually get me?
GAMEMAX specifies 92% or higher efficiency under typical loads. That means less power lost as heat inside the case compared with Bronze or Gold units at the same output, and lower wall draw for the same delivered wattage.
Will the RGB sync with my motherboard?
It supports 5V addressable RGB with motherboard sync and is Aura Sync compatible, with 25 lighting modes and an RGB memory function that retains your setting. You need a 5V ARGB header on your board to drive it.
