PC Building Simulator turns one of the most satisfying hobbies in tech into a full career. You start in a modest workshop, diagnosing faulty machines, carrying out repairs and upgrades, and assembling custom builds from real, licensed components. Then you power them on and see how they perform in 3DMark. It began as a pre-alpha demo downloaded more than 650,000 times and has grown into a detailed hardware and software simulation, rewarding for seasoned builders and welcoming to complete beginners.

Build a Business One Job at a Time

Career mode puts you in charge of your own PC building and repair business. Customers bring a wide range of jobs: a sluggish machine that needs a new drive, a system infected with a virus, a gaming rig due for a graphics card upgrade, or a complete build to a specific spec. You diagnose the problem, order the parts, do the work and get paid, all while watching your bank balance so every job still turns a profit. As you gain experience, more of the parts catalog opens up and the jobs grow more ambitious.

Real Hardware, Accurately Modeled

Licensed components

The marketplace is full of accurately modeled, fully licensed parts from real-world manufacturers, so the cases, motherboards, processors, memory, storage and graphics cards on your bench behave like the hardware they represent. Compatibility matters, and choosing parts that actually fit together is part of the challenge.

Cooling and style

Choose between air coolers and water cooling solutions, or go all out with fully customizable water cooling loops. LED lighting and cable colors let you give each build its own look and turn a functional rig into a showpiece.

Benchmarking and overclocking

Once a machine is assembled, switch it on and run it through 3DMark to see how it scores. If the numbers fall short, head into the BIOS and try overclocking for extra performance. Go carefully, though, because the goal is better results without breaking anything.

Learn How a PC Really Goes Together

If you have ever wondered what is inside the case, PC Building Simulator is a patient teacher. Step-by-step instructions walk you through the order parts should be installed in, and built-in information explains what each component is and what it does. It is a low-stakes way to build confidence before you open up a real machine, and experienced builders get plenty of room to experiment with the hardware they have always wanted to own.

IT Support at Irratech Corp

The IT Expansion comes with the game at no extra cost and adds more than 20 hours of story content. It takes you out of your own workshop and makes you the IT support for Irratech Corp, where the machines you look after belong to a company that needs them working. It is a substantial change of pace that puts your repair and upgrade skills to work in a new setting.
