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.

The plug thing is really overblown IMO, it could have happened to anyone. The important thing is1. Did they fix it, and
2. Did they replace people's burnt computers?
The plug should fit better. Larger and longer pins means more contact area... Need better fitment and tolerances to slide in and click properly each time. Also, the sensing pins are probably unnecessary. Just have an optional 450w bios.

if you cant tell when its actually plugged in all the way, thats a pretty major issue.None of this is a poroblem with the 8 pin, you notice.....

Yeah, I have not seen a 12VHPWR cable personally yet, but from what I have read, it just doesn't seem to "snap" in quite as tight as the current 8-pin PCI-E connectors. Which means even if you know what you are doing as a PC builder, you might not get it fully inserted. I also have to wonder, with the only two GPUs shipping that use being MASSIVE 3-slot and higher than normal height, that maybe NVIDIA should have provided a right-angle connector out of the box. Since because of where the 12VHPR connector is placed, you really have to bend it as it is hitting the side panel immediately. A right-angle connector would alleviate that stress, and might have been able to be inserted fully a lot easier.tamalero - Thursday, December 8, 2022 - link
Just installed my 4090 and I can tell you that you're right. That thing just doesn't snap nor holds itself like the PCIE connectors.I had no idea if it was fully connected or not. and I was worried I would start to bend the connector from the PCB of the card as the connector is very hard to insert.

I don't have one; but from coverage I've seen elsewhere, while the cable doesn't have a satisfying mechanical snap and audible click when inserted a strait pull and wiggle test will quickly dislodge an incompletely inserted cable without disturbing one that is in all the way. It's also recommended to plug power into the card before inserting it into the case so you've got more room to manipulate the wire and to inspect it's insertion.flyingpants265 - Wednesday, December 14, 2022 - link
Cables shouldn't be a thing anymore anyway. Apple's Mac Pro and the stadia devkit don't even use cables at all. Instead of "hiding" them, just eliminate them completely.But yeah, for 600W GPUs, you probably want a right-angle connector.

Yeah, if you plugged this power supply's 12VHPWR cable in halfway as well I'm sure it would melt just as easily. The root issue is it's not easy to tell if it's latched and the sense signals that detect proper connection can do so without the connector actually latching.Techten - Tuesday, December 13, 2022 - link
I have the 850 Watt version of this PSU, and I had to gently create a curve in the 12VHPWR cable to get it in the RTX 4080 using a Corsair 4000D Airflow. I took my time over 5 minutes creating a soft curve and leaving at least 2 inches out of the card with out bending. The Cable was very stiff. There was a satisfying click sound once placed in the 4080 and you could easily see that it was flush with the female adapter of the card.scottj - Thursday, December 8, 2022 - link
Not sure about the Gaming Intelligence thing, but they could at least use a modern USB connector.shabby - Saturday, December 10, 2022 - link
At least its not a usb-b port 😂
