PS5 Slim Quietly Gets an Update: EDM-051 Motherboard, Easier-to-Reach Battery and Revised Cooling

Sony has done it again: no statement, no event and no press release, yet the PS5 Slim has a new internal revision. As reported by Vandal, the change came to light when someone opened up one of the recent Marvel's Wolverine limited-edition consoles and found a different motherboard, identified as EDM-051, along with changes to the cooling system and a CMOS battery that is considerably easier to replace.

It might seem like a minor detail, the kind of thing only people who live with a screwdriver in hand care about, but it isn't. This is the console many of us have plugged in every day to practice, compete or stream. Any change that affects how the hardware is repaired and how it stays cool has a direct impact on its lifespan, and that matters to everyone who pushes the machine for hours on end.

What you need to know

• Sony has introduced a new internal revision of the PS5 Slim without officially announcing it.
• The revision was discovered when a Marvel's Wolverine limited-edition PS5 Slim was taken apart, revealing the EDM-051 motherboard.
• The CR2032 CMOS battery can now be removed and replaced far more easily.
• The design is similar to the one already used in the PS5 Pro.
• There are also changes to the cooling, which, like the rest, aim to simplify manufacturing and maintenance.

What's changing and why the CMOS battery matters

The CR2032 is a small coin-cell battery that preserves certain console settings when the system loses power. It usually lasts for many years, but not forever: sooner or later it runs out, and when that happens it needs replacing. Until now, doing that on the PS5 Slim meant reaching the motherboard through a more involved teardown than you'd like. It wasn't the nightmare of previous generations, but it wasn't a ten-minute job for just anyone either.

With the EDM-051, Sony adopts the approach it had already brought to the PS5 Pro, and getting to the battery becomes much more straightforward. To put it in perspective, here's how things have evolved according to the source:

What about the cooling?

The source confirms that the new revision brings changes to the cooling system, but doesn't specify what they are or whether they improve temperatures or noise. So for now, caution is in order: we know there are modifications, but we don't know their real impact. We'll need more thorough testing before drawing any conclusions about thermal performance.

Our take

Here at Underworld Lordz, we see this as a step in the right direction. Making maintenance easier means extending the life of the hardware, and that especially benefits people who use their console heavily. A competitive team or a creator who streams every day doesn't want a cheap part to force them to take half the machine apart. Sony starting to think about repairability, even with something as small as a battery, is a good sign.

That said, it's not all applause. Rolling out these changes without an official announcement strikes us as a transparency problem. If you modify a product's cooling, consumers deserve to know, just as they deserve to be able to tell which revision they're buying. Right now, the only way to find out is for someone to open up a limited-edition console. That's not communication, that's archaeology. And it's worth being realistic here: the source itself points out that the changes aim to simplify manufacturing and maintenance, meaning there's an industrial motive behind them too, not just a desire to serve players.

If you already own a PS5 Slim, there's no reason to panic or rush to replace it. If you're thinking about buying one, it's worth keeping a close eye on reviews of the EDM-051, especially on the thermal side, since that's what matters most during long competitive gaming sessions.

What do you think?

Does repairability matter to you when choosing a console, or is it enough that it works well out of the box? Should Sony announce these revisions instead of leaving the community to discover them? Tell us where you stand in the team chat or on our Discord: would you buy a PS5 Slim knowing you could repair it yourself?
