The 12V rail is conservatively set, but having the same triggering point under cold and hot conditions is incorrect. Thankfully, this is not the case for over power protection, where the triggering point is notably lower at high temperatures. Moreover, the minor rails have correctly set over current points, which is a pleasant surprise since this is not true in most PSUs. Finally, all other essential protection features are present and work well.

I believe the images are not for this PSU in page 3, and instead are from the SeaSonic series. Notice the AC mains connector is using a different connector than the one in Page 2. Also, there is no “purple” anodized heatsinks, everything’s just black. Refer to the GX III 1050W review to see how it should look. Please fix this problem, thank you.
My bad, fixed. Thanks!
Excellent! Checking the review gallery now.
Also a big thanks for your exact component part number listings on page 2 of each variant of this PSU’s family (1250W, 1050W, 850W, 750W), it helped me a great lot to decide exactly which one of them to consider buying. Shame that Cooler Master doesn’t publish this information, but I always prefer to actually do a comparison between the internal components before considering to purchase a product, so as your review are an excellent source of information, thank you!
