Load regulation should be within 1% at 12V, ideally close to 0.5% deviation. On the minor rails, load regulation is decent.

Ripple Suppression

Test 12V 5V 3.3V 5VSB Pass/Fail
10% Load 10.6 mV 14.1 mV 16.7 mV 8.4 mV Pass
20% Load 10.6 mV 14.1 mV 16.4 mV 8.5 mV Pass
30% Load 11.6 mV 15.3 mV 17.0 mV 8.7 mV Pass
40% Load 12.0 mV 14.0 mV 16.7 mV 9.0 mV Pass
50% Load 15.4 mV 15.1 mV 17.7 mV 9.2 mV Pass
60% Load 19.3 mV 16.0 mV 18.7 mV 9.4 mV Pass
70% Load 22.2 mV 15.8 mV 19.1 mV 9.8 mV Pass
80% Load 26.3 mV 15.4 mV 20.3 mV 11.1 mV Pass
90% Load 27.3 mV 15.7 mV 19.9 mV 12.1 mV Pass
100% Load 35.3 mV 18.6 mV 21.1 mV 13.9 mV Pass
110% Load 33.9 mV 21.8 mV 21.0 mV 13.7 mV Pass
Crossload 1 12.0 mV 18.4 mV 17.5 mV 10.9 mV Pass
Crossload 2 14.6 mV 27.6 mV 17.7 mV 10.1 mV Pass
Crossload 3 11.4 mV 15.5 mV 22.1 mV 10.3 mV Pass
Crossload 4 33.7 mV 16.9 mV 19.3 mV 13.9 mV Pass

Ripple suppression doesn’t stand out, but it is good enough. Ripple at 12V is lower at the 110% test than the full load test because the unit couldn’t complete the 110% load test. It shut down after one minute of load or so.

  1. I should point out that Gamemax has done promotions in the past where they would offer gift cards in exchange for five-star reviews on Amazon, which dampens their credibility somewhat. Also, given that Jiu Meng is the manufacturer behind Aresgame, if this is a sample from the company and not a unit you bought yourself I am doubtful that what a consumer would get would be the same as what is shown here. Regardless, it’s good to see that they are at least capable of making a good PSU. Thanks for the review as always!

  2. It woulb be nice if you can review the top of the line version, their 1300W. At 149$ USD and with the look … many jump on it too with 6,862 review 4.5 Stars.
