Hot Test Results (~45°C Ambient)
The XPG Cybercore is built from components that are capable of tolerating very high temperatures, which gave the PSU an edge while we were testing it inside our hotbox. The efficiency drop was very small, with a marginal average efficiency reduction of 0.4% across the nominal load range. In theory, the XPG Cybercore could receive its 80Plus Platinum certification even if the testing were to take place inside a hotbox. There is no disproportionate efficiency drop when the PSU is heavily loaded either, indicating that it is exceptionally resilient to thermal stressing.
No matter how efficient the XPG Cybercore is, that kind of power output will still produce a significant amount of thermal losses that the PSU will have to deal with. The temperature of the internal components will always be high if the PSU has to work under such adverse conditions, and higher than 60°C on the major active components across any load. Due to the cooling profile, the temperature of the internal components will be high while the unit is lightly loaded, will then drop when the load is moderate, and then keep rising until the unit reaches its maximum capacity. The temperature will reach a worrying level only when the XPG Cybercore is forced to operate at maximum load for prolonged periods of time.
The strange thermal behavior of the XPG Cybercore is due to the cooling fan or, to be more specific, the programmed cooling profile behind it. Regardless whether the unit was operating inside our hotbox or not, the thermal control circuit did not start the fan when the load was low. This was the culprit behind the high temperatures while the unit was only lightly loaded, which then dropped as the fan came on. The speed of the fan did not follow the same profile as when the unit was outside our hotbox though, as it reached its maximum speed with a load of 800 Watts and, naturally, maintained that high speed to the end of the load range.

That fan location is good for those cases that have the cutout in the case. Mine currently has the fan on the switch side.back2future - Friday, March 11, 2022 - link
"This particular model has a maximum speed of 2150 RPM, which is a high rotational speed for a 120 mm fan, but it should not be reaching that speed under normal operating conditions."Astonishingly (relative) small heat sinks.

Finally a PSU worthy of a 2023 notebook.saratoga4 - Saturday, March 12, 2022 - link
With over 100 amps on the 12v rail, I'm curious what happens if a sata connector comes uncrimped and shorts or a cap goes short circuit. Can the supply even detect shorts (which are probably well under 100a) or will it pump in current until the wiring is on fire ?Oxford Guy - Sunday, March 13, 2022 - link
Very loud. Not a good design.Calin - Monday, March 14, 2022 - link
Well, it's made for a "under the desk" tower case. Such is both far from the user, and there's no "direct" sound path (only reflected).So the perceived sound level is far from what - let's say - a gaming laptop would feel like (Asus Rog Zephyrus 14 will go 46 dB within your arms reach, and the highest noise from the PSU was some 52 dB under a desk somewhere. That's four times the perceived noise level in the same conditions - which, in this case, are not.

It’s too loud.I have put PCs into closets and in adjacent rooms. I am very familiar with desks, baffles, and other obstructions.
