Epilogue
Like its 1000W sibling, the Montech Titan PLA 850W is a decent-performing unit, but its overall performance is not competitive, given its high price tag. Even the Montech Titan Gold 850W, belonging to a lower-tier line in Montech’s PSU portfolio, gets a solid performance lead (over 3-4% depending in the voltage input). The good aspects of this unit are the highly efficient platform on all load ranges, the silent operation, the good transient response of the 12V rail at high loads, and the increased amount of provided cables. On the other hand, I would like to see a better transient response at 12V with lower starting loads (e.g., 20% of the PSU’s max capacity) and correctly set protection features. In my book, a PSU’s protection features are among the most crucial factors, so I am very strict regarding their evaluation. As I mentioned in the previous PLA reviews, it is also high time for manufacturers to add fan failure protection in PSUs costing over 100 dollars, since this protection will save the day if anything happens to the fan and won’t allow the PSU to get immense stress by operating at high temperatures.
Before investing in a new power supply, read my Best ATX v3.x PSUs article to check all alternative PSU offerings. You help me a lot by using my affiliate links, which don’t increase the product’s price. I get a commission from Amazon every time you do it, which can make a difference for me, especially now that I am on my own, working exclusively for my media and not for someone else.

I noticed that the test results, especially the fan control, differ between this review and the report 24PS2426A for same model. Did the review test a new revision that is not yet on the market?
Seems, I found the relevant report – 23PS2308A. This appears to be an earlier revision of the power supply.
I can use a different test sample than the one listed on Cyben
