AI summary — not a quote

The Montech Century II 850W is highly regarded in the PC building community as a top-tier value proposition, frequently cited as an 'A-tier' or 'A-rated' power supply that competes with premium brands at a lower price point. It is praised for its 80+ Gold efficiency, fully modular design, and 10-year warranty. However, while the sentiment is strongly positive, some users express hesitation due to the manufacturer's relatively short history in the high-end PSU market and isolated reports of quality control concerns.

Pros

  • Excellent value, often priced between $80 and $90 USD
  • Ranked as an A-tier or A-rated unit on popular community PSU tier lists
  • Fully modular design with 80+ Gold certification
  • Includes a 10-year warranty

Cons

  • Isolated reports of poor quality control and cable melting issues on non-12V-2x6 connectors
  • Manufacturer has a limited track record compared to established PSU brands
  • Long-term reliability is still unproven as the unit has only been on the market for a few years

You dont need to spend that much, Montech Century II 850W still around 90USD.

If you're willing to spend an extra ~~$20-25, the Montech CENTURY II 850W is a A- rated, fully modular unit with a 10 year warranty.

If you want cheap nonmodular but good quality I'd go with a Asrock PRO 750g $55 on Newegg,

Yes it's safe, but if you're buying new you can get an Asrock PRO 750G for $55+tax and is larger and better

If you're in the US, and on a budget, the Asrock Pro 750G is a good, B+ rated PSU, but it only has a three year warranty and is non-modular(can't choose which cables to connect).
