As I am writing this, the Thermaltake Toughpower Grand RGB 1050 W costs €219, while the Chieftronic GPU-1050FC is much more affordable at €188. Unless you are in desperate need of RGB lighting for your PSU, the GPU-1050FC is a much more appealing choice. it also manages higher performance than several good PSUs in this wattage range, including the Corsair HX1000, which starts to show its age and needs a platform upgrade.

The transient response, load regulation, and ripple suppression are good, and the same goes for the build quality, although I would like to see an FDB instead of a rifle bearing fan. That having been said, rifle bearing fans can still last for quite a while if they are not exposed at high operating temperatures (>35 °C) for prolonged periods of time. Speaking of the fan, its speed profile needs tuning because it is aggressive at even normal operating temperatures. Given the platform's efficiency and selection of components highly tolerable to high temperatures, there is headroom for relaxing the fan profile.

The main problem with this PSU is that Chieftronic sought to provide as many connectors as possible, so they had two EPS connectors installed on the same cable. Drawing the maximum power that these EPS connectors can deliver will have the socket of the modular board struggle considerably despite the 16AWG gauge up to the first EPS connector, and it may even melt under extreme usage scenarios. With a proper multi-rail design, OCP would kick in and protect the PSU in such a scenario, but this is a single +12 V rail PSU, so there is no such safeguard. Six PCIe and EPS connectors on dedicated cables would have been much better and more than enough for this unit. Chieftronic should do just that with a reversion of this product, and since the PCIe and EPS cables are electrically compatible, it won't cost them anything to make the change. Using this PSU with such energy-hungry CPUs as the AMD Ryzen Threadripper 3990X would also be safe with a proper cable configuration even though it can consume more than 450 W under load with PBO set to automatically overclock the processor.
