The B12 BC Series is available in the standard ATX Form Factor and in wattages that are most common for a PC system. The Seasonic B12 BC achieves 80 PLUS® Bronze standard of providing at least 82 %, 85 % and 82 % power usage efficiency at 20 %, 50 % and 100 % operating loads, respectively. This efficiency, combined with Active Power Factor Correction, enables the B12 BC series power supplies to lessen energy waste, which translates into savings on the costs of energy costs for its users. In addition to being greatly efficient, the B12 BC units utilize the LLC resonant converter design, and the industry’s leading Smart and Silent Fan Control (S2FC). 80 PLUS BRONZE The 80 PLUS Bronze certification indicates that a high percentage of the electricity is converted into useful power, therefore there is less heat lost and more money saved on the electricity bill. The 80 PLUS Bronze certification guarantees greater than 82 %, 85 % and 82 % efficiency at 20 %, 50 % and 100% operating loads, respectively. Seasonic’s B12 BC Series is an economical choice with great performance and high built-in value.

I ordered a custom keyboard with milky yellow pro switches and a few mods. I ordered it already assembled out of a lack of time and it came in really quickly.
When I got the chance, I opened it to take a few changes and was really pleased with the quality. It was gasket mount despite not having had to option to choose that on the website and it had case foam. A tape mod later the board sounds brilliant. The switches are well lubed… can only recomment and look forward to my next order 😊
If you’re after something clacky look no further, these switches are also super poppy. I would spring swap them tho since the stock 57g spring is too light imo
