ordinary model, nothing special

Overall, the power supply gives the impression of being high quality: compact, cool, and completely silent when idle. There's a 0% RPM mode button — up to about 40% load, the fan doesn't spin, and it really works. It's convenient for assembly, plus it looks neat, the cables are of normal stiffness, and the bag for them included is a small but pleasant touch.

However, under load, something starts that ruins the whole impression. With the connected 12V-2×6, a cyclic sound appears, very similar to the whistling or buzzing of inductors. At first, I blamed the hard drive, then the video card, checked everything one by one — no, it's definitely the power supply. It's not a loud roar, but it's intrusive and irritating, especially when the system is generally quiet.

There are no issues with operation: the voltages are stable, nothing disconnects, the computer doesn't shut down, and everything is okay with diagnostics. But expectations were higher — after all, it's ATX 3.1, with stated "top-notch" circuitry and Japanese components. And once again MSI: it looks good on paper, but in practice, there's a nuance that's hard to ignore. If it weren't for that noise under load — it would be a very successful power supply.
It is really cool, it is really powerful. Nice packaging, a bag with cables. Small size of the power supply unit.
Sings under load.

Top power supply, has all Japanese capacitors, for powering 3090ti, 7500f
enough to power the not very energy-efficient 3090ti, the presence of a bag, modularity of cables
there may be hard wires

The MSI MPG PCIE5 power supply has been part of my setup for a while now, and overall it's a modern, solid device—decent material quality, looks good, and the support for PCIe 5.0 seems promising for the future. But there's one nuance worth knowing.

In normal mode, without heavy load, everything is quiet and calm—almost inaudible. But once the graphics card or system is under load, the PSU starts emitting a not-so-pleasant cyclical sound. It's not just fan noise or a gentle cooling breath—it's a rhythmic tone that noticeably stands out among other components. I can't say for sure whether it's the fan making that noise or some electrical element in the circuits buzzing/ringing under load, but it stands out more than you'd like from a PSU positioned above the mid-range segment.

When the system is calm—you almost forget about the PSU. But during games or heavy tasks, when the graphics card is active—this sound starts to very noticeably "talk" with the rest of the case noises, and it's not always pleasant. My system is quiet, and you really only notice this sound when you take off your headphones...at night. So I wouldn't say it's that loud.

To me, it's not critical or a sign that it's breaking—just a fact you notice in everyday use. If silence in your PC is very important, it's worth keeping this in mind. Otherwise, it comfortably handles a 5070, 12600KF, tons of fans, 3 SSDs, and 1 HDD without heating up.
Cool, modern, lots of connectors.
The sound... at first I thought it was a throttle on the video card, but no, it's still the same block.
