We would like to thank Gigabyte for supplying the review sample.
Gigabyte is mostly known for its motherboards and graphics cards, rather than its power supplies. As such, I found it quite surprising that their site lists a total of 77 PSU models! While most of these address the mainstream market, there are also enough higher-end models on offer.
According to Gigabyte, the P750GM and P850GM are ideal for power-hungry graphics cards, like the NVIDIA RTX 3080 and newly released AMD RX 6800 and RX 6800XT. Both PSUs are fully modular and compact because of their limited depth of 140 mm.
The P750GM is 80 PLUS Gold certified, as well as ETA-A and LAMBDA-A- certified for, respectively, efficiency and noise on the Cybenetics scale. These are relatively high ratings, showing that this is an efficient and quiet PSU. Gigabyte supports this product with a five-year warranty, which is satisfactory—PSU life expectancy highly depends on operating conditions and mains grid power quality. To boost reliability, a hydraulic bearing fan is used, at least according to Gigabyte. As it turns out, it is actually a plain rifle bearing fan.
Moreover, the bulk cap is provided by a Japanese manufacturer, so it will last for a while. Lastly, all protection features are advertised as present, which has it look like a fine product on paper. I plan to run many tests to check on whether these claims from Gigabyte are valid.
