The Lian Li EDGE EG1000 1000W ATX 3.1 PSU Review: Power On The Edge

Cold Test Results (~25°C Ambient Temperature)

For the testing of PSUs, we are using high precision electronic loads with a maximum power draw of 2700 Watts, a Rigol DS5042M 40 MHz oscilloscope, an Extech 380803 power analyzer, two high precision UNI-T UT-325 digital thermometers, an Extech HD600 SPL meter, a self-designed hotbox and various other bits and parts. For a thorough explanation of our testing methodology and more details on our equipment, please refer to our How We Test PSUs - 2014 Pipeline post.

The Lian Li EG1000 Platinum ATX 3.1 PSU meets the 80Plus Platinum certification standards when the input voltage is 115 VAC, even if only barely. When tested with a 115 VAC input, this PSU achieves an average nominal load efficiency of 90.4% across its operational range from 20% to 100% of its capacity, increasing to 92.3% when operated with a 230 VAC input. It would not pass the 80Plus Platinum requirements with an input voltage of 230 VAC as the half-load efficiency is not nearly high enough. The efficiency under very low load conditions is acceptably high.

The Lian Li EG1000 Platinum ATX 3.1 PSU demonstrates fair thermal performance and acoustic characteristics during room temperature testing. The fan does not activate immediately but starts when the load is just under 100 Watts. As the load increases, the fan speed escalates almost linearly alongside with the load. However, due to the PSU's small proportions and 120 mm fan, internal temperatures are slightly higher than other units in its class. Acoustically, the fan operates quietly only at loads lower than 300 Watts, which will become noticeable in a quiet environment and keep getting louder as the load increases.
