The Deepcool PX1200G is a good power supply, meeting the strict ATX v3.0 and PCIe 5.0 requirements. Although the average noise output is high, this is due to the increased fan speeds at high loads. At light and moderate loads, the PSU has a silent operation, and given its high capacity, you won’t hear it during most tasks. This depends, though, on your system’s configuration.
The compact dimensions are an asset, and the three dedicated 6+2 pin cables ensure compatibility with graphics cards not utilizing a 12VHPWR connector. The number of SATA connectors might be decreased compared to other offerings, but I don’t think many users need more than eight of these connectors for their systems, given the popularity of NVMe drives. The only issue with the PX1200G is the notably higher price, in the US market that I checked, compared to the Montech Titan Gold and Thermaltake GF3 models with similar capacity. Given that all units use the same platform, are covered by the same warranty, and offer similar performance levels, it will be hard for a user to pay more to get Deepcool’s offering.

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.
