Which should you buy, Antec HCG1000 Gold Extreme or Montech Century II 850W?

The Antec HCG1000 Gold Extreme is the one to take for anyone who wants fully modular cabling with native 12V-2x6 support and systems where a 10-year warranty and Gold-tier efficiency matter, though it is the wrong buy for builds needing more than 1000W of continuous headroom and buyers who need the smallest possible SFX/SFX-L footprint. It is equally the pick for builders targeting an RTX 4080/4090 or RTX 5080/5090-class high-end gaming build. Take the Montech Century II 850W for the most budget-conscious builders who still want genuine 850W Gold-rated, fully modular specs. This is specifically flagged as unusual value in the current market. The same goes for anyone comparing a similarly-priced 750W and 850W unit. Current guidance specifically recommends taking the extra headroom here when the price gap is this small. It is the wrong buy for buyers who weigh long brand history heavily in a PSU purchase. Seasonic or Corsair, both covered elsewhere on this site, carry longer established track records for buyers who prioritize that specifically.

    Verdict

    Antec HCG1000 Gold Extreme

    8.3 / 10 Expert Rating

    A solid 1000W Gold-rated ATX unit for an RTX 4080/4090 or RTX 5080/5090-class high-end gaming build, held back only by the usual mid-tier compromises on cabling and OEM sourcing.
