Sony has quietly introduced a new PlayStation 5 Slim hardware revision featuring an EDM-051 motherboard, a user-accessible CR2032 CMOS coin cell battery, and a revised liquid metal cooling layout, webtekno.com reported. Released without a formal company announcement, the updated internal design first appeared inside the Wolverine Limited Edition console, according to hardware technician @Modyficator89. Sony has implemented various hardware revisions to the PS5 since its initial 2020 launch, moving from original model updates to the smaller PS5 Slim.
Sony introduces simplified internal layout with the EDM-051 motherboard
The latest revision departs significantly from original launch models and earlier Slim iterations by adopting a redesigned mainboard structure. The EDM-051 motherboard features a simplified layout alongside a more optimized, cost-focused HDMI retimer integrated circuit. Blog.r10.net noted that while the exterior chassis remains unchanged, the internal arrangement streamlines component placement and connection pathways. This hardware revision continues a series of changes Sony previously made to the PS5 Slim.
Relocated CMOS Battery for Long-Term Maintenance
Previous PlayStation 5 iterations integrated the system’s CMOS battery in a manner that complicated replacement once the cell degraded over time. The new revision addresses this by incorporating a readily accessible CR2032 coin cell battery slot. Blog.r10.net reported that this modification simplifies future maintenance routines and preserves core system functions as consoles age. In earlier PlayStation models, the depletion of the CMOS battery could cause issues with certain system functions.
Redesigned Liquid Metal Cooling System
Cooling architecture represents the most substantial engineering shift in the new revision. Sony re-engineered the protective boundary surrounding the APU, shrinking the direct-contact surface area and adjusting the gasket materials compared to earlier Slim builds. Webtekno.com stated that this configuration borrows heavily from the PS5 Pro’s containment approach, establishing a tighter seal designed to prevent liquid metal leakage or displacement over extended periods of use. The redesign uses a different cooler block structure and materials than previous Slim models to prevent liquid metal-related failures.
