We would like to thank Chieftec for supplying the review sample.

I already reviewed the Polaris model with 750 W maximum power output, so when Chieftec offered me the 1050 W version, I was curious what more is on offer besides increased power output. The OEM remains High Power. To be more specific, Chieftec used the High Power HP1-H1050GD-F14C model as a base for the Polaris 1050 unit. This platform focuses on a high performance per dollar ratio rather than pure performance. On the 80 PLUS scale, the Polaris 1050 is rated as Gold, while Cybenetics gave it its Platinum efficiency and Cybenetics Standard S++ noise ratings, the latter of which denotes 30–35 dBA average noise output.

This is a fully modular PSU with enough connectors to deliver its power smoothly. Moreover, it uses a fluid dynamic bearing fan, which has the short warranty look odd. Most manufacturers provide at least five years, some even ten or twelve, as with the Seasonic Prime models, while Chieftec only offers two years for all their PSU models. At €125 including VAT, pricing is reasonable at least. The downside is that you won't find any Chieftec products in the US, which is a shame since the aggressive pricing schemes would make their products a good option for users in need of a strong power supply.
