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.

    When I first saw this, I thought it was pretty clever. It doesn't have a cluttered front end because the power circuitry is on a single PCB.

    But they missed an opportunity to improve cooling by poking some holes in the front end. Yes, it'll dump heat back into the case, but it fixes airflow dead zones in and at the front of the PSU.

    I suspect what you mentioned would also improve the average cooling capability as shown in testing as well. However, there is nothing stopping a perspective buyer from taking the cover off and going to town with a drill - though a drill press with a template would be the most adequate option. Alternatively you could take it to a machine shop that could stamp out a 5mm honeycomb grid in couple minutes, most shops have those dies. Reply

    Agreed, but that's what I have a dremel tool for :D Reply

    in psu alone, it's not an issue, anything that heats up can just be slapped with a thermal pad, and have a component to case as "good enough" cooling.
    Still I love the idea of those doing double duty, so random opening that just perfectly blow on random VRM, that would be a perfectionist dream.

    So so close.

    I understand Lian Li needs to try and grow beyond the case market, but I wish they'd still cater to some niches in that market.

    For instance, I wish I could buy a black, aluminum tower case for the Pi 5. The NUC market is another area where it'd be nice if we had old school anodized black aluminum Lian Li cases available.

    Even in the conventional case market, I feel like Lian Li has gone too far in one direction. This year, I bought a small footprint mid-tower ATX case and none of the current models from Lian Li ticked all of my boxes.

    Lian Li does custom orders. Reply

    What "boxes" didn't they tick? Reply

    Lian Li does a tremendous amount of industrial and commercial products. Computer cases are arguably their smallest segment. Reply

    Interesting PSU, but you'd better carefully check if it meets your use case. For me, in 2 different builds it would just not work. Reply
