A powerful and highly efficient next-generation computer power supply with modern circuitry, featuring a highly efficient half-bridge topology with DC-DC converters, fully modular cables, and a substantial set of built-in protections. This model is next-gen, fully compatible with the PCIe 5.0 interface and ATX 3.0 standard. The manufacturer positions it as a mid-range product designed to power high-performance gaming systems with top/near-top video card models like RTX 4060/4070/4080, equipped with a 16-pin power connector.

It has a unique feature of power connectors with yellow contacts at both ends of the cable, making it clear whether the power cable is fully inserted or not. This helps avoid the common issue of melted 16-pin connectors on GeForce RTX 4000 graphics cards. Unlike the original MSI MAG, the MAG PCIE5’s efficiency has increased, earning it a gold quality certificate instead of bronze.

Unnecessary cables can now be completely detached, preventing unwanted mess from cluttering the interior with unnecessary wires and obstructing the view of the lighting. Otherwise, it closely resembles its predecessor. Inside, it houses a high-quality component base with a resonant LLC converter, synchronous rectifier, and DC-DC converters. The wide main power rail can deliver up to 100% of the PSU's total power, providing stable and efficient power even to very powerful and overclocked hardware like the Core i9 and GeForce RTX 4080. It also includes essential protective tools, including protection against overvoltage, excessive current, and short circuits.

Model overview based on user reviews  
The MSI MAG GL PCIE5 power supply unit has received mixed reviews from users. While some appreciate its nice appearance and affordable price, significant concerns have been raised about its performance. Users have reported issues such as fan noise, with the fan being described as loud even when idle and lacking a semi-active cooling system. Additionally, there are complaints about electronic humming and buzzing noises affecting audio devices, which persist even when using external sound cards. Some users experienced vibrations and crackling noises from the unit, leading to dissatisfaction. Despite its good quality and protections, the noise issues and lack of a semi-passive fan mode have led some to suggest considering other options or investing in a PSU with better cooling features.

good model, done well
15 December 2025 
Bought this PSU for RX 7800XT, Intel 14600. In the system case, there is also 1x HDD, SSD, M2. In terms of power, it's more than enough, and there have been no problems for over a year. The main downside is that it is very noisy, even without a load, but it doesn't produce any whining or crackling sounds.

Crackling in the headphones, and a terrible cooler

Place an orange smiley face, but it didn't feel right, otherwise it'd be 7/10 only because of the cooler.

A solid power supply for its price, which, unfortunately, you should not buy. It is of good quality, heavy (for its size), with all protections and a good efficiency rating. However, there is one serious nuance. I don't feel like detailing the pros; as a PSU in a vacuum, it is good, so it's better to switch to the nuance right away. I don't have the problems with PSU crackling or headphone noise that one of the reviewers mentioned, but I fully agree about the fan. It really lacks a semi-active operating system. In my PC, there are a total of 9 fans + a VRM fan + a pump, and they all together make less noise than the single fan in this PSU. The problem lies precisely in its operation without load, as in games/movies/music, the sound from the headphones usually drowns out the PSU fan, and it's not audible, so there are no issues in such scenarios. It was hard to get used to in the first days, but now after 2 months, I've adapted and can't say there is any discomfort. Perhaps someone will find it useful for reference; I measured it with a sound level meter: 40 dB noise from the fan without load, ~30 dB noise from the entire PC, excluding the PSU fan and without load (~700 rpm fans, 1500 rpm pump), ~33-35 dB sound level at head height, assuming the computer is on the desk. Of course, these are not critical levels, and my old DeepCool DA700 was significantly noisier, but still, for this price, I would recommend people pay a little extra and look for a PSU with a semi-active cooling system, especially if the other fans in your PC are expensive and quiet, as this fan will definitely spoil the whole picture.
