Which should you buy, Antec HCG850 Gold Extreme or Gigabyte UD850GM PG5?
The Antec HCG850 Gold Extreme is the one to take for RTX 4080-class single-GPU builds and buyers wanting a 10-year warranty at 850W, though it is the wrong buy for Multi-GPU or extreme workstation loads and SFF builds needing SFX. The Gigabyte UD850GM PG5 suits Gigabyte AORUS-themed builds and RTX 4070 Ti/4080-class GPUs wanting native ATX 3.1, though it is not built for buyers wanting the most field-proven, established brand and Multi-GPU workstation loads.

Our rating of the Gigabyte UD850GM PG5 (8/10): A modern, well-specced ATX 3.1 Gold unit for Gigabyte-themed builds, docked slightly for being a newer, less field-tested platform.
