Everything you need to know about the PS5 Chassis B

Throughout the life of a comfort its manufacturer is launching reviewsalthough they are not always advertised. In the case of PlayStation, it is quite common to talk about 'Fat' and 'Slim' to differentiate the original machine from the revision that was released later, with a smaller size. However, within each version there are also changes. Each revision receives a name and must be marked on the product label.

What is the PlayStation 5 Chassis B?

Between one revision and another there may be small aesthetic changes, alterations of materials for other more resistant —or cheaper—, differences between components due to a change in supply or even modifications that seek to polish errors or add improvements. Most of the time, this goes unnoticed, but this has not been the case with the PlayStation 5 Chassis B. In this post we will tell you everything you need to know about this new body for the next generation console from Sony.

Chassis B is the first significant PS5 review. Production began approx. mid 2021, in May, and it is the model that is being marketed in stores in Europe —if you manage to find one due to the low level of stock, of course.

The great novelty of this model is that weighs 300 grams less than the original model. However, although there are more differences, the hardware features and capabilities are identical to the 2020 version.

What consoles mount the new Chasis B?

In order not to get confused, we are going to talk only about the console models that are marketed in Europe, since there are multiple variants depending on the region in which the product is marketed and it does not make sense to talk about the models that we cannot access in our market.

As you know, the PlayStation 5 is sold in two different formats: with and without blu-ray drive. The original PS5 model with a disc drive was called CFI-1016A, while the digital version was codenamed CFI-1016B.

Well, the first models that have been marketed in our region as of mid-2021 receive the names of IFC-1116A (version with disc player) and IFC-1116B (purely digital version). These two models mount the new Chasis B.

By the way, to differentiate, many media will refer to these models as '2020 10X' and '2021 11X'. if you wonder where to buy this console, all the models of PS5 that are currently in stores are from this new specification. So there is no real choice.

How to identify if your console is Chassis A or Chassis B

identify chassis ps5

If you've recently purchased your console and aren't sure which model you have, you can find out from several different ways. You have the model number both on the box the console came in and on a label on the equipment itself. The serial number of the PlayStation 5 console can also be found on the inside of the PS5. If you need to know this information —either to buy a compatible accessory or even to process something under the guarantee—, you have to do the following. siguiente:

  • Remove the dock from your PlayStation 5 console.
  • Look for the sticker that the serial number is printed on (if you're placing the console vertically, it's right at the bottom of the console).
  • Now pay attention to the label:
    • El serial number from the console is the code consisting of 17 characters.
    • El model number It is just what we talked about in the previous section. It is headed by the initials 'CFI', followed by a number and a letter. That letter is what determines the chassis model of your PlayStation 5 console.

If you need to use this information later, it is recommended that you take a photo of the label with your mobile phone or write down the two codes on a piece of paper to avoid having to disassemble the base of the console every time you need this information.

Differences between Chassis A and Chassis B of PS5

It's not just the weight that's the big difference between these two PlayStation models. Sony has taken note of some of the problems that the original PS5 had and has tried to fix them in this new edition. Almost all of this redesign is focused on improving the thermal performance of the console and lowering its manufacturing costs to a certain extent. The result is a much lighter console, with a much simpler dissipation system. Simplifying the set could be counterproductive, but as we will see a little later with very technical and exhaustive tests, the improvement of this new version exists. Of course, we must not rule out that new models appear in the future —either Slim or a future C Chasis— that further improve the heat dissipation of the PlayStation 5.

If you are curious about How has this PlayStation 5 Chassis B improved compared to Chassis A, Here's everything you need to know:

Differences in the heatsink

Like any current performance device, the PS5 does not escape having certain difficulties in terms of the heat dissipation it means. This does not mean that we will have thermal throttling during our games (as it can happen in some laptop models Gaming), but it is seen that they have discovered a new more efficient method of lowering the temperature console.

Chassis B mounts a new heatsink, which is curiously less bulky, but which is more efficient than the original. You can see a comparison between the two pieces in this video by Austin Evans, who dissects the two models of the console and puts both parts side by side so you can see the differences. He dares to say with the naked eye that it is worse, but as we will see in the next paragraph, appearances are deceiving.

Surely now you are wondering if the change of heatsink has been worth it. At the user level, it is difficult to draw conclusions. However the youtuber specialized in hardware Gamers nexus has made multiple test of performance to both consoles to draw conclusions. In general, the difference exists, but according to this expert, Sony could improve the temperatures even more by applying liquid metal instead of thermal paste the different this from the console. Even so, it is unlikely that Sony will apply this measure. Liquid metal is a great alternative to thermal paste, but applying this compound is risky. First of all, if misapplied, it can cause a short circuit with other components. And on the other hand, it can become corrosive on some metallic materials.

From a global point of view, the components that benefit most from the change are the VRM, which significantly reduce its temperature, guaranteeing longer shelf life at the same time that they optimize a more stable power delivery, since a good cooling of these components ensures that there are no voltage drops. In this way, the CPU frequency of the console will remain stable. They exist until almost 6 degrees difference comparing one model with the other. Lto RAM memory it also sees its temperature reduced by a couple of degrees. However, the youtuber He emphasizes that the memory of the PS5 fails due to temperature at 95 or 110 degrees depending on the memory manufacturer that we have had in our unit.

Despite these changes, it should be remembered that we must make good use of the console to ensure that its useful life is not reduced by temperature. We should never box it in, nor cover its vents. The PS5, like any next-generation console or any computer Gaming, it must be located in a place where it can get clean air, in order to reduce the temperature of its internal components. In the same way, we must be especially careful if we have pets at home, because the hair in suspension can clog the ventilation slots, even more so if we use the console close to the ground. In such cases, it is recommended to do a small console maintenance from time to time. What's more, Sony has thought of a system of filter cleaning so that any inexperienced user can do it at home, just as we explain in this video:

New base for the console

The PS5 can be placed both vertically and horizontally. However, to stand it up requires a accessory that comes in the console box itself. It is a circular base that is screwed to the bottom of the console with a screw.

In the original model, the screw was very thin, and required the use of a tool such as a screwdriver, yes or yes. In the new revision, Sony has chosen to use a screw with a wider head. In the same way, they have widened the hole in the base so that we can insert our fingers and tighten the screw directly with our hands. However, it would have been more sensible to put a carabiner-shaped screw, as many of the tripod shoes on cameras have. Quite simply, because those with big hands will still have to use a screwdriver to assemble the base.

The changes in the 2022 model

At the end of 2022, Sony made a new modification to its console. The Japanese replaced the 7 nanometer AMD Oberon chip and went on to equip an improved chip with a more interesting lithographic process. Specifically, the PlayStation 5 now uses a chip AMD OberonPlus, built under a lithographic process of 6 nanometers from TSMC.

This model gets the CFI-1202 identifier, but no known codename. That is, for the moment, it has not been named as 'PS5 Chassis C' or anything like that. Among the improvements of this new chip is greater energy efficiency, less energy loss in the form of heat and the possibility of further reducing the dissipation and power systems.

Will a Slim model arrive one day?

As we have seen, the Chassis B of the PS5 has significantly reduced its dissipation system without affecting its performance when it comes to cooling the equipment. This data is interesting in order to fantasize about a future Slim model of the console. And it is that, to tell the truth, the PlayStation 5 is a huge device that does not fit in any living room furniture.

We know that at some point, Sony will have to produce a smaller version of its console. On this occasion there are many players who ask for it, no longer for aesthetics, but for pure ergonomics. However, this generation does not seem that the 'bikini operation' is going to be so simple. Some experts in modding They have tried to reduce the thickness of the console and have come to the conclusion that the PS5 has two major hindrances: el heat and power consumption. Sony's console is huge not only because it has to dissipate a lot of thermal energy, but also because it packs a gigantic power supply. However, with the changes that have been made with the new chip (CFI-1202 identifier), the ground is favorable. It may not be long before we see a slightly thinner PlayStation 5.

The modders They have already made their versions

Either by looking for virality or by trying to do the experiment, there are a couple of y They have already tried to slim down the PlayStation 5, although some with certain traps.

El youtuber sfdx show made its own PS5 Slim by designing its own case, opting for liquid cooling and keeping the reader. The result is still a rather bulky console, but with a much more compact size than the original.

To the other extreme went the youtuber British DIY Perks. Matt designed his own liquid cooling pad for the PlayStation 5 PCB. Similar to the pads sold to connect a GPU board to a water cooling system. The result was spectacular, with a very attractive copper finish. However, criticism was not long in coming. DIY Perks managed to reduce the thickness of its console but that does not mean that huge pieces like the power supply or as part of the refrigeration circuit are located outside the console. These mods further demonstrate how complicated it is to cool down the Sony PlayStation 5. Will there be any solution for the future?

Only AMD can solve the problems of PS5

For many experts, the only possibility that we will see a Slim model of the console is that AMD releases a PS5 APU revision with an inferior lithograph that consumes less energy. This would allow a more restrained source to be used and would generate less heat, also allowing for a lighter dissipation which, as a consequence, would guarantee the possibility of creating a much more compact and lighter PS5. But definitely, there is still time for that to happen.
