A glance at the light loads table is always useful, as the PSU will typically operate at light loads. As you can see, the fan doesn’t spin at light loads, despite the high ambient temperatures that I applied.

Yello, I’m in India and only have two same priced PSU options: MSI MAG A750GL and Deepcool PN750M, everything else is priced at 1.5 to 2 times these psu. They are almost identical units, but I’m still confused which to get. Which would you suggest?
THANKS! 😁
MSI
Hi Aris, quick clarification, when I asked about the MSI A750GL vs PN750M (under the GLS review), did you mean the GL or the GLS model in your reply? I only have the GL variant available.
The one you had in your answer.
