Sony has reportedly made changes to the PS5 Slim without officially announcing them, according to a technician known as Modyfikator89, who took apart the PS5 Slim Digital from the Marvel’s Wolverine bundle. Inside the console, the motherboard, labeled EDM-051, includes a replaceable CR2032 button battery, similar to those used in watches to keep time and settings when the device is not in use. This motherboard also features liquid metal protection around the APU — the chip that combines the processor and graphics unit — which is similar to the protection used in the PS5 Pro, released in November 2024. The Marvel’s Wolverine bundle was released on September 15, 2026, in limited quantities and included an 825 GB PS5 Slim Digital, a yellow DualSense controller, and the game Marvel’s Wolverine, which is compatible with QSSR, an AI upscaling technique available on standard PS5 consoles. Sony has not officially confirmed these modifications, and the EDM-051 motherboard has only been found in this particular console. The replaceable battery is not mentioned in the manual that comes with the console, despite being the same type used in many watches. In earlier PS5 Slim models, replacing the battery required bypassing the cooling system, but the new motherboard makes it more accessible, similar to the PS5 Pro. A test by the Hikikomori Media channel showed that removing the battery still allowed the console to launch disc-based and digital games, but access to PS Plus titles was blocked. The console is also delivered with an older manual that does not mention the new battery. The liquid metal protection around the APU has been improved, reducing the surface area in direct contact with the metal and retaining it more effectively, as seen in the PS5 Pro. The radiator, which helps dissipate heat, has also changed in both construction and material. Sony has also updated the HDMI retimer, a chip that reshapes the video signal before sending it to the TV, with a cheaper and more optimized version. However, repairers should be cautious, as the motherboards, radiators, and small connectors in this revision may not be compatible with earlier PS5 Slim models. On the software side, no changes have been made, and the console still uses the same system as other PS5 models. This system has been exploited by a jailbreak that works through the browser on most PS5 models running firmware versions 7.00 to 13.60. Sony has become accustomed to these subtle modifications since the PS5 Slim was introduced in 2023. In September 2025, the storage capacity of the PS5 Slim Digital sold in Europe was reduced from 1 TB to 825 GB, with leaks predicting the change before a video detailed the new design. A few months later, a European model no longer required an online activation for its disc drive. For now, only the PS5 Slim from the Marvel’s Wolverine bundle has been disassembled, and Sony has not stated when the EDM-051 motherboard will be available in PS5 Slim models sold separately.
