Who each one is for
The Antec Signature 1300 Platinum suits builders targeting a workstation or multi-GPU build with serious headroom and anyone who wants fully modular cabling with native 12V-2x6 support, though it is the wrong buy for builds needing more than 1300W of continuous headroom and buyers who need the smallest possible SFX/SFX-L footprint. Buy the Silverstone ST75F-PT for 24/7 workstations where efficiency pays off over time and high-end single-GPU builds wanting Platinum efficiency, though it is not built for SFF builds needing SFX/SFX-L sizing and extreme multi-GPU loads above 750W. Our rating of the Antec Signature 1300 Platinum (8.8/10): A best-in-class 1300W Platinum-rated ATX unit for a workstation or multi-GPU build with serious headroom, held back only by its premium price.
