SilverStone's Strider Platinum lineup now includes 1000 and 1200 watt models with a depth of only 140 mm. These are both fully modular ATX PSUs, and 80 Plus Platinum certified.
The compact 140 mm depth is popular with small form-factor builds – and sometimes a requirement for a fully modular PSU like this depending on the enclosure. The power density is obviously getting really high for 2018, and 1200W is likely the highest you will find at 140 mm.
Pricing and release dates have not been revealed just yet for either power supply.
