The OCP triggering points at 12V are below 130%, but I would like to see lower OCP in hot conditions. Moreover, OCP is set too high on the minor rails. Over power protection is set at around 125%, but it would be lower at hight temperatures.

  1. Hello, i’m trying to choose between Deepcool PX850G, MSI MPG A850G and Asus rog strix 850w gold aura. Leaning towards Asus, but it is ~70$ more expensive than MSI and Deepcool. Which one is the best and which one is the worst? Which should i choose between MSI and Deepcool?

      1. it turns out there is no point in buying Deepcool PX850G white? I am choosing a power supply for a white assembly and wanted this model in white

  2. Did you notice any coil whine with this PSU? I bought a Corsair Rm850x and it has a slight steam whistle type noise even while idle.

      1. Oops I meant the Rm850e.

        Is coil whine generally common amongst most PSUs? I noticed that the capacitors on the Rm850e are non-japanese, could that be a contributing factor?

        Thank you

        1. in general for me, since I have lots of test systems, coil whine has to do mostly with the graphics card in use and the current use (e.g. game menu or desktop)
