The latest CFI-1200 series standard edition is now as light as the digital edition at the time of its launch, despite an additional disc drive.
Each console has been reduced from 4.5kg to 3.9kg, according to the specifications – although it is unclear how Sony accomplished the weight loss.
The PS5 model is currently only available in Australia, with a Japan launch planned for September 15.
UK and worldwide distribution have yet to be announced, if they are on the cards.
Previous weight changes have included last year’s CFI-1100A model, which featured a smaller heatsink.
Meanwhile, Sony recently announced a price hike for its PS5 consoles in several countries due to inflation.
Sony’s CEO Jim Ryan said: “We’re seeing high global inflation rates, as well as adverse currency trends, impacting consumers and creating pressure on many industries.
“Based on these challenging economic conditions, SIE has made the difficult decision to increase the recommended retail price of PlayStation 5 in select markets.”
Several regions including Europe, Japan, China, Mexico, Australia, and Canada saw an upsurge of 12.5 per cent in retail price, while the United States was spared the increased price tag.
