Hot Test Results (~45°C Ambient Temperature)
The Lian Li EG1000 Platinum ATX 3.1 PSU maintains commendable efficiency during hot testing. The unit achieves an average nominal load efficiency of 89.1% with a 115 VAC input and 91% with a 230 VAC input. This indicates some degradation due to the elevated ambient temperature but within reasonable limits. There are signs of thermal stress at maximum load, with greater efficiency degradation.
Even though the ambient temperature is significantly higher, the fan once again does not start right up, but once the load is a little higher than 70 Watts. It maintains its linear speed profile but accelerates more rapidly, reaching its maximum speed just below a 900-watt load. It keeps fairly low noise levels when the load is below 300-400 Watts, but the noise output will increase rapidly after that point, with the EG1000 becoming very loud at loads above 800 Watts.
The Lian Li EG1000 Platinum's relatively compact size does not do it any favors when it comes to thermal performance. The internal temperatures are on the high side for an 80Plus Platinum-certified unit, although they stay within safe operational limits. There is a small spike at maximum load due to the fan's inability to increase its speed any further, but the final temperatures are far too low to trigger an OTP event.

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.Techie4Us - Saturday, July 6, 2024 - link
Agreed, but that's what I have a dremel tool for :Ddeil - Wednesday, July 10, 2024 - link
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.'Power on the edge' All you needed on that sub was an L:
'Power on the ledge'

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.ballsystemlord - Friday, July 5, 2024 - link
What "boxes" didn't they tick?Slash3 - Saturday, July 6, 2024 - link
Lian Li does a tremendous amount of industrial and commercial products. Computer cases are arguably their smallest segment.croc - Saturday, July 6, 2024 - link
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.
