Antec High Current Gamer 520 W Power Supply Review

Overload Tests

Voltages at the power supply outputs must be as “clean” as possible, with no noise or oscillation (also known as “ripple”). The maximum ripple and noise levels allowed are 120 mV for +12 V and -12 V outputs, and 50 mV for +5 V, +3.3 V and +5VSB outputs. All values are peak-to-peak figures. We consider a power supply as being top-notch if it can produce half or less of the maximum allowed ripple and noise levels.

The Antec High Current Gamer 520 W provided really low ripple and noise levels, as you can see in the table below.

Input	Test 1	Test 2	Test 3	Test 4	Test 5
+12VA	7.2 mV	8.4 mV	10.2 mV	13.4 mV	21.8 mV
+12VB	7.6 mV	8.8 mV	11.0 mV	24.4 mV	22.8 mV
+5 V	8.2 mV	8.2 mV	9.2 mV	9.8 mV	11.6 mV
+3.3 V	8.4 mV	10.4 mV	11.8 mV	13.4 mV	15.6 mV
+5VSB	10.2 mV	11.0 mV	13.4 mV	15.8 mV	17.6 mV
-12 V	11.8 mV	13.6 mV	16.0 mV	17.8 mV	21.2 mV

Below you can see the waveforms of the outputs during test five.

Figure 19: +12VB input from load tester during test five at 520.4 W (22.8 mV)

Figure 20: +5V rail during test five at 520.4 W (11.6 mV)

Figure 21: +3.3 V rail during test five at 520.4 W (15.6 mV)

Let’s see if we can pull more than 520 W from this unit.
