In today’s review I will look at the last member of MSI’s MAG A-GLS line, with 650W max power. Like its 750W sibling, the MAG A+50GLS, is made by one of the largest Chinese PSU OEMs, Huntkey. Read the full review to learn more.
The MSI MAG A650GLS PCIE5 is (or will be) included in my best ATX v3.x & PCIe 5.x PSU picks article.
There is no doubt that the MSI MAG A-GL is a decently performing line, but it’s not suitable for users who want silent operating products. Hence, MSI thought to offer the MAG A-GLS(ilent) line with PSUs featuring much more relaxed fan-speed profiles than the A-GL ones. I have already evaluated the 1000W and 850W models of the line and noticed that indeed, the average noise difference with the plain “GL” model, which uses a different platform, is substantial. In this review, I will evaluate the A850GLS. Briefly, the 1000W and 850W models of the line are made by CWT, while Huntkey makes the two lower-capacity ones.

A side note, all A-GLS units are tested and certified by Cybenetics.
The MAG A650GLS is Platinum certified in the Cybenetics standard, and it also has a Cybenetics A noise rating. Its dimensions are standard for a 750W PSU, measuring 150mm in depth. At the time of the review, I was unaware of the product’s price.

April 11, 2024.. on the XPG Core Reactor II VE 650W PSU Review.. you stated “The 600W setting of the 12+4 pin connector is overkill! It should normally be set at 300W.”
Because it used the 600W spec of 16AWG, you dinged it. Now because the MSI took your advice & used the 300W spec of 18AWG, you ding them.!!
I don’t ding the 16AWG gauge but the fact that they use 600W on a 650W PSU. For MSI’s case I had to talk directly with Intel to confirm that they are ok with 18AWG when the PSU has its port set at 300W.
So to wrap up, having a 600W set port on a 650W PSU is NOT good! This is what I said.
thank you for the clarification. i misunderstood the word connector as indicting cable, whereas you used connector in the context of the psu port.
i enjoy reading your reviews & opinions. great work.
glad to hear that standards are subject to interpretation. i did read your article on 12V-2×6 Cables? Are ALL The Same?. where it is summarized by Intel … According to Intel, using 18AWG gauges on a 12V-2×6 cable is incorrect, even if this is used by 750W/850W PSUs, where the maximum power setting is 300W. would it be possible to update that article to state your new conversation with Intel that it is ok with 18AWG on a port set at 300W?
