MEG Ai1300P PSU - Unusual Heat That's [Supposedly] Intended

Recently built a new computer with the following components:

Board: ASUS ROG Maximus Z790 Hero
VGA: Gigabyte GeForce RTX 4090 24GB GDDR6X
PSU: MSI MEG Ai1300P (plugged into motherboard via G.I. Port, Mini USB to JUSB 9-pin)
CPU: Intel Core i9-13900K
MEM: Corsair Dominator Platinum RGB DDR5 32GB (2x16GB) 5600MHz C36
COOLER: ARCTIC Liquid Freezer II 360
OS: Windows 10 64bit Professional, 22H2

Temperatures for all components other than the PSU are as expected. When idle/light internet browsing, CPU doesn't exceed 35 C and GPU doesn't exceed 42 C. Benchmarking in CBR32, the CPU does not exceed 88 C. Benchmarking in Unigine Heaven, the GPU does not exceed 58 C (it's also power limited to 70%). No undervolting nor underclocking has been applied to any component.

Physically, my computer feels cool near the intake and exhaust fans. However, I do feel a good deal of warmth coming from the back of my case near the PSU. To the point where I'm physically noticing it without going out of my way to check. And only in the back, not at the bottom near the PSU intake fan.

Monitoring data in MSI Center during light/medium internet browsing (Firefox, ~15 open tabs, no media playing), the PSU is temperature reads 48 C. To me, that seems warmer than it should be, especially given my experience with other PSUs in similar builds. However, MSI Support told me that's normal.

Even if I sit idle at the desktop when nothing is open, and Output Wattage is 60-80W, PSU temperature is over 40 C.

I'm confused because I found a picture that someone posted on this forum from when they were playing New World (game) and their PSU temperature is much less than mine while I'm simply browsing the internet, and their Output Wattage is much higher.

But again, according the MSI Support my idle/internet browsing temperatures are normal.

The perhaps bigger issue is that the fan never kicks on, even while pushing the PC. While I ran Unigine Heaven, the Output Wattage never exceeded ~480W. And as I'm running Unigine Heaven, every minute or so the PSU temperature increased. No matter how high it increased, the PSU fan never started.

I eventually stopped the software at around 68-69 C because I wasn't interested in seeing how hot it would get before it shut itself off.

MSI Support has told me so much conflicting information that I'm simply not sure what is true. One support member told me the PSU would turn itself off at 70 C, another told me that's at 105 C. One support member told me the fan would start once the PSU reaches 70 C, another told me that it won't start until power output is greater than 1000W. All the while, every time this information is being communicated to me, I kindly ask them to confirm [due to so much conflicting information], I'm put on hold, then I'm told it's confirmed. When I raise previous conflicting communications, I'm told the last support member must have been mistaken.

This PSU is already a replacement from the first MEG Ai1300P that I purchased because of a factory defect in which transistors put in the wrong location were physically preventing cables from being plugged in. I'm now trying to determine if I have another defective unit, but it's difficult for me due to all the conflicting messaging from MSI Support. Either way, according to them, after providing all of this information, they're telling me that there's no issue. But there's so much heat coming from this unit, in temperature readings but more importantly to me, physically, that I can't imagine there's no issue here.

I found the following image posted in a different thread:

Since it appears to be a marketing material, perhaps this is the truth?

In terms of setting a "Customized" fan speed, couple notes on that. First off, MSI Center itself is quite buggy and exhibits inconsistent behavior. For example, I set the Fan Speed to Customized, then set it back to Auto, however every time I opened the software it would be switched back to Customized. No matter what I tried, the setting would not stick/carry forward. Then the issue started happening the other way around. Eventually I had to reinstall the program just to reset it. It's not soley me with this issue because I found others reporting similar elsewhere, for example:

That's from about a month ago but I've seen others that date further back. I've yet to see a comment from MSI addressing the software issues.

There's also no way to set a fan curve or anything of that nature, so even if I did specify a manual RPM, I'd then have to make further adjustments depending on my scenario. For example I set it to X speed continuously, but then there's a scenario in which it should be running faster. At the end of the day, setting a "Customized" fan speed isn't really a solve here.

Due to my work in AI and other areas, I'll need to push this computer, so to say.

Could someone please answer the following:
1) MSI is claiming my idle/light internet browsing PSU temperatures (generally 43 - 47 C) are normal. Is that actually the case? If so, how does that make sense given the example image that I provided from someone else on this forum in which New World was being run?

2) Had I kept Unigine Heaven running, would the fan have eventually started? That's still not clear to me.

3) Does anyone have a recommendation into addressing the heat exhibited by the unit, whether that's idle or internet browsing or AI work or gaming or whatever? I've got a 1200W PSU from a different company and no matter how hard I push the output wattage, physically it never feels as warm as this unit does while it's idle. Unfortunately I wouldn't be able to return this PSU, so that's not an option.

4) Any other comments/suggestions in general.
 
I don't know what could be the reason, he was always very polite in his replies, taking everything we said onboard, an exemplary user.

We arrived at some logical conclusions in the end, and i don't think it's necessary to hide any of that process. It happens to me all the time as well, for example that i didn't think of a certain thing until someone else mentions it as the possible explanation, and then it's obvious that my line of thinking wasn't entirely correct. But everyone will understand that, it's a process to arrive somewhere, no need to edit anything.

We all get more experienced as we go along, and we try to work together to get to the bottom of things. Sometimes we are convinced it's one thing, then later it's shown to be another, but let's leave it like it is in the thread, maybe the "one thing" that was not right there could be the solution for something else, or give someone a good idea while reading it.

Whats up with the edits? You just made all replies irrelevant which might have served other users having similar questions
I saw those early on, I guessed they were some server error or something, anyway, edits are back to normal now!

Wow - what a difference this made. The fan on my PSU is running at ~706 RPM and now that area behind my case is nice and cool. Temperature reading is now showing 29 C which is the lowest I've seen it since building this PC. Also can't even hear the fan running. And just as you stated, I don't even need MSI Center to start upon booting Windows.

Thanks so much for this advice! Guess I'll see what happens in the long run.

You are welcome and what Big Difference right, my whole PC runs idle between 28-32c, which is so much better for me as I'm in a tiny room here and before the fan setting my room was like a freaking stove.

Imagine all that Heat when gaming in a room this small,... Ignore the emptiness, Just laid a Laminate floor to help with cooling my room as it was getting that hot, seriously hot!

Got that flooring all through the house
IS good never to get hot and in winter is never cold on the feet

And Warm romm solution

That's my next purchase to buy, there's no way I'm going through another summer like we did last year here in the UK, that was too much for me.
Though the laminate flooring does help keep it cool and cuts down dust as long as you clean often, just have to remember to slip the slippers on as I climb out of bed in winter lol

Been looking at some on Amazon but the one I'm looking at is a portable AC unit that will hopefully fit under my desk, there around £350 atm.
 
Hi I have the same PSU, and the max temps that this PSU capacitors are rated for is 105°

my Idle temps are 23°C and Gaming temps maxed out at 55°C
While gaming, the following graph from their marketing held true, since once the load reached 55% the fans kicked in

if you have a second monitor I suggest using a portion of that screen to monitor your pc that's what i'm doing haha as you can see, these monitoring tools are always on when my pc is operating
