PC Building Simulator: Career Guide

A practical guide to PC Building Simulator's career mode: how jobs, money and levels work, a reliable diagnose-and-fix routine, building and overclocking for 3DMark targets, workshop upgrades, and what the IT and Esports expansions add.

Researched September 2026 — current as of v1.15.3 (April 2022) plus the January 2023 analytics update. Live games change; check the linked sources if something differs.

Version note: PC Building Simulator (2019) is still sold on Steam but receives no new content; its last content update was v1.15 (March 2022). The sequel, PC Building Simulator 2, launched on the Epic Games Store in October 2022. Everything here is about the original.

Quick Start

1. Career mode is a business sim. You run a repair and build shop. Jobs arrive by email; finishing them pays money and XP.
2. Read every job email twice. Customers specify exactly what they want (a part, a benchmark score, a colour). Missing a detail lowers your rating.
3. Levels unlock parts. Many high-end components are locked behind your shop level; early jobs are simple on purpose.
4. Keep a cash buffer. You pay rent and electricity bills. Going into debt early slows everything.
5. Order parts with the right delivery speed. Faster delivery costs more; plan jobs a day ahead to use the cheap option.
6. Never forget thermal paste. It is so common there is an achievement for forgetting it.
7. Benchmarks use 3DMark. Jobs asking for a score need the right CPU/GPU combo — and sometimes overclocking.
8. Customer ratings matter. Your star rating is tracked (achievements at 4, 4.5 and 5 stars), so meet every stated requirement.
9. Salvage and resell. Spare parts and whole spare PCs can be sold for money.
10. Try How to Build a PC mode first if you have never built a real PC — it walks through the assembly order step by step.

Game Modes

Career Mode Basics

Jobs

Common job types:

• Full builds to a spec or budget.
• Upgrades (add a GPU, more RAM, a new drive).
• Repairs — find and replace a broken component.
• Virus removal — scan and clean the system in the OS.
• Cleaning — remove dust buildup from components.
• Benchmark targets — hit a 3DMark score; "Perfection" is getting the exact requested score.

Money

• Income comes from completed jobs and selling spare parts/PCs.
• Expenses: parts, delivery, rent, electricity and workshop upgrades.
• Achievements track milestones such as $1,000, $10,000, $100,000 and $1,000,000 in the bank — and getting into $3,000 of debt.

Levels and unlocks

• XP from jobs raises your level. Achievements mark levels 6, 12, 18, 24 and 30.
• Higher levels unlock newer, more expensive parts and better jobs.

Workshop upgrades

• Second and third workbench — work on more PCs at once.
• Storage cupboard — more space for parts.
• Bigger workshops — upgrade to a bigger workshop, then an even bigger one.
• Uncle Tim's Bargain Basement — Mystery Parts Packs; a gamble for cheap parts.
• DEKOR catalogue — cosmetic items for your shop.

Diagnose-and-Fix Routine

Use this checklist for repair jobs:

1. Read the complaint in the email.
2. Power on the PC. Does it boot? Blue screen? No display?
3. Open the OS and check software issues: run the antivirus for viruses, check storage and drivers as needed.
4. Inspect the inside. Look for dust (clean it), missing thermal paste, loose or missing cables, and wrongly seated parts.
5. Test suspect parts by swapping in known-good parts from your inventory.
6. Check temperatures and stability if overclocked — undo aggressive overclocks that cause blue screens.
7. Only replace what the customer asked for or what is actually broken; extra changes can annoy them.

Building a PC in the Game

Standard assembly order (mirrors real life):

1. Case open, side panel off.
2. Motherboard prep: CPU, thermal paste, cooler, RAM, M.2 drives.
3. Install the motherboard into the case.
4. PSU, then storage drives.
5. GPU into the PCIe slot.
6. Cables: 24-pin motherboard, CPU power, GPU power, SATA, fan/RGB headers.
7. Close up, power on, install OS if needed.

Compatibility checks the game enforces:

• CPU socket must match the motherboard.
• RAM type and speed must be supported.
• Case size must fit the motherboard form factor, GPU length and cooler height.
• PSU wattage must cover the build.

3DMark Targets and Overclocking

• Scores depend mainly on CPU and GPU. If a job needs a certain score, adjust those first.
• RAM has a smaller effect; dual-channel helps.
• Overclocking in the BIOS raises clocks and voltages. Too much and the PC blue-screens or the CPU breaks (there is an achievement for breaking one).
• Cooling matters. Better air coolers, AIOs, or custom water loops allow higher stable overclocks.
• The Perfection achievement asks for the exact requested score — use small overclock steps to hit it.

Step-by-step overclocking:

1. Increase the multiplier or frequency a small step.
2. Run 3DMark and watch temperatures.
3. If it blue-screens, step back and raise voltage slightly — or stop.
4. Stay within safe temperatures for the cooler you have.

Cooling

The v1.15.x patches fixed many AIO and radiator clipping/collision issues in specific cases, so if a cooler would not fit before, it may now.

Expansions and DLC

• IT Expansion (free): work for Irratech Corp. Complete tickets (TikkIT achievements at 25, 50, 100 tickets) and story jobs, some with your colleague Natalia.
• Esports Expansion (paid): manage tech for esports teams, move into bigger and elite workshops, set up arenas under time pressure, and earn gifts from players.
• Workshop DLC from brands (Fractal Design, EVGA, AORUS, Overclockers UK, NZXT, Republic of Gamers, Razer) add themed workshops and parts.
• The Maxed Out Edition bundles the base game with nine DLC items.

DLC at a glance

The Build & Benchmark Bundle pairs the game with the real 3DMark if you want to compare your own PC against the in-game scores.

Esports Expansion career in brief

The Esports Expansion runs as its own career rather than a mode inside the base career. You maintain gear for players on esports teams, work to a weekly budget, and handle match-day setups in the Arena, where some tasks are timed. Things worth knowing before you start:

• Timed Arena jobs. Two achievements (Setup Wizard and Clean Sweep) ask you to set up the whole team or clear a disaster in 120 seconds or less. Lay out spare parts before match day.
• Gifts and likes. Players reward good service with gifts; there are 26 to collect, and achievements at 1, 10, 15 and all 26 gifts plus one for 20 Likes from a single player.
• Career end rating. Your career ends with a bronze, silver or gold watch depending on performance. Gold is the Top Tier Technician achievement.
• Team loyalty. One achievement asks you to stay with the Vandals for the whole career, another to work for every available company — they need separate playthroughs.
• Workshops. You move into a bigger workshop and later the elite workshop as you progress.

Achievement Plan

The game has over 90 Steam achievements. Most base-career ones fall out of one long career save; do the "silly" ones in a spare save or Free Build where possible.

Grind tips: the $1,000,000 and 500-jobs achievements are the long ones. Sell leftover parts instead of hoarding (except for "So you're the reason why the prices are so high?", which wants 100 GPUs in your inventory, and Hoarder, which wants every possible part — leave those for last, when money is no object).

Update History (final support era)

If a cooler or radiator refused to fit in a specific case on an older save, it is worth retrying — much of the 2022 patching targeted exactly those collisions.

Common Mistakes to Avoid

• Forgetting thermal paste — the CPU overheats.
• Not plugging in power cables, especially CPU or GPU power.
• Ordering parts you do not need and burning cash.
• Over-overclocking customer PCs without enough cooling.
• Going into debt early by buying workshop upgrades too soon.
• Ignoring the email requirements (colour, brand, exact score).

Advanced Tips

• Keep a small stock of common parts (budget PSUs, RAM, storage) to finish simple jobs without waiting for deliveries.
• Batch jobs that need the same parts in one order.
• Sell leftover parts and build spare PCs to sell once you have extra workbenches.
• Use Free Build to test builds and overclock settings before trying them on a paid job.
• Steam Workshop wallpapers work in the in-game OS (v1.15.3 fixed a case where the integration failed).
• Build your office PC up early. Several achievements (3DMark 5,000/10,000/20,000, 128GB RAM, Threadripper, custom loop) are tied to your own office machine, not customer PCs — and it is the safe place to experiment with overclocks.
• Controller and Steam Deck: v1.15.3 added PS5 controller support and the on-screen keyboard on Steam Deck.
