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.

we need to support anandtech, when innerfidelity went away, there is only commercials reviews. we need anandtech.com, we need some kind of honest authority, otherwise it's just chaos, and shit!!!hMunster - Wednesday, December 14, 2022 - link
This is getting ridiculous. I remember when 200-220W were normal and a 250W PSU was considered large.Glock24 - Monday, December 19, 2022 - link
What catched my attention is the "PCIE5" in the name, what do they want to achieve with that?GreenReaper - Tuesday, December 20, 2022 - link
Well, 12VHPWR is an amendment to the PCIe 5.0 specification by the PCI Special Interest Group: http://jongerow.com/12VHPWR/Presumably graphics cards supporting PCIe 5.0 will also have greater adoption of the new socket, so this indicates readiness for them. However, we don't see any of those on the market yet. It also seems to have been added to ATX 3.0, so if you want to be certified as such you (might? at a certain power?) have to include one.

Who the hell needs a 1300W PSU for personal use? It’s almost like wasting energy to play computer games is coolYoussef 2010 - Friday, December 30, 2022 - link
The 12VHPWR adapters aren't poorly designed. The users were not fully seating the connectors as concluded by GamersNexus and further confirmed by Nvidia themselves. A SIMPLE leaflet instructing the users to verify that there's no gap between the connector and the plug was all that was required. It was an oversightMiddleman - Monday, February 6, 2023 - link
Its not about using 1300watts, its about running at 50% load efficiently.
