Pros: Sleek design - modular -quiet -more than adequate.
Cons: If anything, some longer cables - but this can be solved with after market extensions to match your build.
Overall Review: This power supply ticks the boxes for me. If you want something straight forward that doesnt pull punches here it is. Modular power supplies are just the future. A lot of more affordable affixed cable PSUs are slowly phasing out for the more preferential modular design. I have gotten to a point where I often skip over companies if its not at least semi modular, so this to me is a nice affordable option that covers the bases. 85-87% under load is about the average with idle sitting closer to the 90s. Its a simplistic design and no ketchup and mustard colored cables. Cable extensions to customize the look are easy enough to put with it if you prefer the not shiny black glossy cables. It supports SLI but as this stands now; youd have to have a pretty big wallet and know when stock is available for the GPU crisis. If you are unaware what I am talking about 2021 has been a tough year for the GPU market on both sides. It currently (no pun intended) is powering a 3900x and 5700XT, and while other components draw power those are the real hogs. I am perfectly satisfied with the PMG750. What it is, is what I am looking for. The PMG750 being relatively affordable and being modular are my top two priorities. The quietness is a nice factor also. I dont know who the OEM is but if Newegg had Rosewill go with Super Flower for these PSUs Id say they made a great choice. The overall quality seems to be Super Flower to me but if not, whoever the OEM is has hit satisfactory marks in my book.
