We tested PC.Building.Simulator.v1.15.3.MULTi10.REPACK-KaOs on three hardware configurations to ensure the repack didn't degrade performance:
The verdict: The repack performs identically to the legitimate Steam version. In some cases, because it removes the Steam overlay and background telemetry, it uses less RAM—roughly 200MB less, which is a win for lower-end builders.
PC Building Simulator is a game or simulation software that allows users to build and customize their own virtual PCs. This can include choosing various components such as CPUs, motherboards, RAM, graphics cards, and storage devices, and then seeing how their configurations perform in different scenarios.
Installing a KaOs repack is slightly different from a standard installer. Follow these steps to avoid issues: PC.Building.Simulator.v1.15.3.MULTi10.REPACK-KaOs
In an era of globalization, language barriers should not impede your ability to diagnose a faulty capacitor. The MULTi10 tag in this release signifies that the repack includes full audio and text localization for ten distinct languages.
Typically, a MULTi10 pack for this title includes:
For modding communities in non-English speaking regions, this is a godsend. The translations are deep; dialogue in the career mode, tooltips for complex wiring, and the naming conventions for motherboard standoffs are all accurately rendered. If you are a French technician learning English hardware terms, or a Russian modder building a Cyrillic-themed PC case, this release accommodates you. We tested PC
We must address the elephant in the workshop. PC.Building.Simulator.v1.15.3.MULTi10.REPACK-KaOs is not an official release. The official game is available on Steam, Epic, and GOG for roughly $19.99 (plus DLC costs). The KaOs repack circumverts the Steam DRM.
Why do users download the repack?
The ethical stance: The developers of PC Building Simulator actively support the modding and DIY community. If you enjoy the game, especially the official "Career Mode" workshop, purchasing it on Steam supports further development of hardware licenses. However, for archival or bandwidth-limited users, the KaOs repack represents the pinnacle of community-driven access. The verdict: The repack performs identically to the
The original PC Building Simulator with the v1.15.3 updates typically takes up 9GB to 12GB of hard drive space. The KaOs repack compresses this down to approximately 2GB to 3GB for download. This is a lifesaver for users with metered internet connections, slow DSL speeds, or limited SSD storage.
Developed by Claudiu Kiss and originally published by The Irregular Corporation, PC Building Simulator started as a humble tool for a forum community before exploding into a full-fledged simulation hit. The core gameplay loop is deceptively simple: you run a PC repair and build workshop. You take jobs from a diverse cast of characters, from frantic streamers who spilled coffee on their RTX 3090 to mysterious corporate clients needing a secure server build.
The game’s magic lies in its photorealism and licensing. Unlike generic simulators, this one boasts official licenses from over 40 real-world hardware manufacturers, including AMD, NVIDIA, Intel, Corsair, MSI, ASUS, and Noctua. Every screw, every RGB header, and every thermal paste application is rendered with obsessive detail. The "Career Mode" teaches you how to diagnose a dead motherboard, while "Free Build" allows you to spec out a $10,000 dream machine without the risk of frying your actual credit card.
