Antec EA 750 Green PSU Review

Antec EA 750 green PSU is made to deliver efficient power to the motherboard, but at lower electric consumption. It efficiently delivers 750 Watts of reliable Continuous Power while meeting the Bronze level of efficiency from 80 PLUS. EarthWatts power supply offers Universal Input to automatically work on any power grid on the planet, and a 135 mm double ball bearing fan to keep cool.

The EA-750 Green PSU is compatible with ATX12V v2.3 and EPS12V v2.91 specifications. This PSU features Universal Input, which automatically senses when you connect the power supply to any AC power source between 100 ~ 240V, eliminating the need to set a voltage switch. The EA-750 Green also features Active Power Factor Correction (Active PFC), which improves the power factor value of the PSU by altering the input current wave shape, helping to transmit energy across the grid.

A variety of industrial-grade safety circuitry will help protect your computer: OCP (Over Current Protection), OVP (Over Voltage Protection), SCP (Short Circuit Protection), OPP (Over Power Protection) OTP (Over Temperature Protection) and SIP (Surge & Inrush Protection).

We used high precision electronic loads with a maximum power draw of 2700 Watts, a 40 MHz oscilloscope, an power analyzer, two high precision digital thermometers, an SPL meter, a self-designed hotbox, etc. to test the PSU.

Honoring its 80 Plus Platinum certification, it displays outstanding performance at room temperature. The peak efficiency is 94.3% at 50% load and the average within the nominal load range (20% to 100% of the unit's capacity) is an astonishing 92.9%. The EA-750 performs well under low loads as well, with the efficiency plummeting only when the load is less than 50 Watts.
