SilverStone introduces a new SFX-L power supply capable of continuously supplying 1,200W - the Extreme 1200R Platinum. The power supply has enough juice to power the most power-hungry, such as the GeForce RTX 4090, one of the best graphics cards on the market.
The Extreme 1200R Platinum is SilverStone's highest-rated SFX-L power supply, rated for Cybenetics Platinum. To summarize, Cybenetics' Platinum indicates the power supply is between 89% and 91% efficient. This compact PSU promises to supply 1,200W continuous output rated for 24/7 use with 50 degrees Celcius operating temperature and provides 100A through 12V rail. The SFX-L Extreme 1200R Platinum uses Japanese capacitors and all the protection expected from a high-grade power supply.

It complies with the SFX12V 4.1 standard and PCIe CEM 5 specification. SilverStone also includes the 12V-2x6 power connector by default, giving a more reliable connection than the 12VHPWR standard, hence avoiding burnout. This SFX-L power supply has a 120mm silent fan with fluid dynamic bearing.
As expected, such power supplies have all the connectors a user would ever need. The following is the complete specification:
The Extreme 1200R Platinum has a five-year warranty. No pricing or launch date is mentioned, though it will likely be available just in time for the RTX 40 Super series graphics cards. It's not a moment too soon, as some have already started shifting to newer ATX standards while providing 12V-2x6 cable. FSP has been including this connector standard for a few months, and Seasonic has its way of assuring its users that the 12V-2x6 is perfectly fine.
With small form factors becoming more popular, even with flagship graphics cards, the Extreme 1200R Platinum will likely cater to compact but powerful SFF builds.
