Hot Test Results (~45°C Ambient)
The resistance of the MSI MEG Ai1300P PCIE5 unit to adverse ambient conditions is astonishing, with the unit hardly affected at all while operating inside our hotbox. There is a practically negligible efficiency degradation of 0.2-0.3% depending on the load, a figure four to six times lower than other similar designs. There is very little additional degradation under heavy loads, suggesting that the components of the MSI MEG Ai1300P PCIE5 are not thermally stressed at all.
Despite the exceptional resilience of the PSU against high ambient temperatures and its 80Plus Platinum efficiency levels, the losses of a unit this powerful sum up to over 100 Watts under high loads. These losses do increase the internal temperature of the PSU significantly but the cooling system of the MSI MEG Ai1300P PCIE5 proves to be more than adequate, as the temperature of the critical components does not get anywhere near critical levels during our testing. As a matter of fact, the MSI MEG Ai1300P PCIE5 delivers lower temperature figures than many units with significantly larger bodies and fans do.
The sizable heatsinks of the MSI MEG Ai1300P PCIE5 seem to be collaborating excellently with the 120 mm PowerLogic fan at keeping the temperature of the critical parts low. With the PSU inside our hotbox, the fan started quicker and sped up even faster, reaching its maximum speed while the PSU was at just 70% load. Regardless, the internal temperatures of the unit kept rising almost linearly and were kept within safe levels.

That's a lot of bullshit to go through just to amuse yourself though. There are less power intensive and expensive ways to get the same amount of entertainment.Threska - Saturday, December 10, 2022 - link
I imagine vibrators don't use that much. :-DTheinsanegamerN - Saturday, December 10, 2022 - link
yeah but in the summer I'm outside doing things, not playing bideo gamies.Those are for winter when its too Fing cold to go outside.

So don't buy it. IMO these manufacturers are leaving a lot of performance on the table, there's just too much overheard built into both the hardware and software. Maybe if these things were redesigned from the ground up (like Apple's M1, but better) we'd see much better performance gains.My question is this: after every card out there can do 4k 120fps, what exactly is left? 8k doesn't even seem worth it at all, and neither does raytracing really. VR still sucks a decade later. Personally I'm a big supporter of ultrawide/surround gaming. But I can't really think of anything else.

Excellent review.It occurred to me that you might want to link to your discussion of the ATX 3.0 power excursion testing challenges somewhere on the "Conclusion" page, perhaps the third paragraph there.
It's new, and for those readers who skim the first page then jump to the last, it's worth their time to read it. (It's worth their time to read every word, but habits need a push to change in this case.)

For $350, this unit is too loud. There should be an offering with a larger chassis and a 140mm fan. Others can do it, so can you MSI.Samus - Friday, December 9, 2022 - link
Very disappointed in the fan myself. They should have made the case longer to put in a 140mm. Really odd design choice to restrict themselves on a flagship product with a short length PSU chassis.Oxford Guy - Friday, December 9, 2022 - link
These things should have 200mm Noctua fans.Tomatotech - Sunday, December 11, 2022 - link
Why is a (too small) 120mm fan or a (too large) 140mm fan acceptable but a (right size) 135mm fan forbidden due to patent issues?Can you patent a specific size of fan? Or a specific size of any commonly used item?

I tried reading this Chinese one, which does mention a 135mm fan in one dimension, but the wording is impenetrable. It expires in 2024, so perhaps if it is relevant it will permit expansion later. https://patents.google.com/patent/CN100498151C/en
