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.

- 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

Seasonic is widely regarded as a "gold standard" manufacturer in the power supply market, frequently recommended for its long-term reliability and industry-leading warranties. Unlike many competitors that rebrand third-party units, Seasonic is a primary manufacturer (OEM), which contributes to its reputation for consistent quality. However, experienced builders emphasize that while the brand is prestigious, users should still evaluate specific models rather than buying on name alone, as the company has produced lower-tier units in the past.
Pros
- Exceptional warranty periods, often ranging from 10 to 12 years.
- High reputation for reliability and protecting expensive components.
- Primary manufacturer (OEM) that designs and builds its own units.
- Generally positive reputation for customer service and RMA processes.
Cons
- Premium pricing compared to other high-quality alternatives.
- Occasional "dud" product lines (e.g., S12iii) that do not meet the brand's typical high standards.
- Small Form Factor (SFX) models may lag behind competitors in adopting the latest PCI-E power standards.

Some PSUs have claimed to have used thermistors to shutdown in case of bad load. AsRock did it and apparently it's a gimmick and does as much as tits on a boar. SeaSonic promised something but haven't seen it yet.
A quality 850W unit from Seasonic, Corsair or be quiet! would remove all doubt and protect a $600+ GPU investment.
All hail Seasonic.
Whatever size, get a Seasonic. Their individually braided cables makes working with them easy peasy.
Grab a solid 750W Gold PSU from Corsair/Seasonic/MSI
