- How to install a CPU in Fix PCs: carry the PC to the workbench, unscrew the old CPU, seat the replacement, and reconnect cables.
- Screws and cables must be fully seated before the game registers the part as installed.
- Match the CPU tier to the customer's ticket — wrong tiers force you to redo the job.
- Run the benchmark after install to confirm the fix and collect your Cash payment.
- High-end CPUs unlock at Level 15, so early orders use Stock CPU swaps.
How CPU Installation Works in Fix PCs
In Fix PCs, CPU installation follows the same physical screw-and-cable system as every other repair in the game. You can't swap a processor while the PC sits on a random counter — the workbench is the only place where disassembly and part installation happen. Before touching the CPU, the diagnostic tool should confirm that the processor is actually the failing component, since replacing a healthy CPU wastes expensive inventory for zero payout benefit.
Here's how the main installation scenarios compare:
| Scenario | When It Happens | Key Requirement |
|---|---|---|
| Faulty CPU swap | Diagnostic scan flags the CPU | Unscrew old CPU, seat correct-tier replacement |
| Customer upgrade ticket | Ticket requests a better processor | Match the exact tier listed on the ticket |
| Full build order | Assembling a PC from scratch | Install CPU before closing the case |
| Reseat only | CPU is loose, not dead | Remove, check contacts, reinstall firmly |
Faulty Swap
- Most common CPU job
- Diagnose first, then unscrew
- Stock CPU fits most early orders
Upgrade Ticket
- Higher payout
- Tier must match ticket exactly
- High-End CPU unlocks at Level 15
Reseat Job
- Cheapest fix
- No new part needed
- Check power cables too
Only pull the CPU after the diagnostic tool confirms it's the problem. Swapping a working processor burns inventory cost without increasing the repair payout.
Step-by-Step: Installing a CPU at the Workbench
The full installation flow takes under a minute once you're familiar with the interaction system. Every step below mirrors the game's screw and cable mechanics.
Bring the PC to the workbench
Pick up the customer's PC with left-click, carry it to your workbench, and press E to place it down. The build view opens when you click the placed machine.
Open the case
Hold left-click on each side-panel screw and follow the on-screen motion to twist them out. Set the panel aside — you need clear access to the motherboard area.
Disconnect attached cables
Check for a power cable or cooler connector attached near the CPU socket. Click the connector and pull in the indicated direction to unplug it.
Remove the old CPU
Unscrew the CPU from its socket using the same twist motion. The part only detaches when every screw is fully out — leftover screws are the most common reason parts won't come free.
Install the replacement CPU
Open your inventory with Tab, select the correct replacement from your parts stock, and slot it into the socket. Screw it firmly into place until the game registers it as installed.
Reconnect cables and close up
Reattach any cables you unplugged, making sure connectors are fully seated. Screw the side panel back on — a loose panel can block the benchmark from starting.
Plug in, power on, and benchmark
Connect the PC to power, flip the PSU switch, and power it on. Run the benchmark: a passing score confirms the install; a failure means something is still loose.
If the PC won't power on after a CPU install, confirm the PSU cable is connected to the motherboard and the PSU's physical switch is flipped. This is the top cause of "dead" machines after reassembly.
CPU Parts and Benchmark Impact
The CPU tier you install directly affects benchmark scores and payout. Of the 192 parts in the game, processors range from the cheap Stock CPU unlocked at Level 1 to the High-End Overclockable CPU at Level 15.
| CPU Part | Unlock Level | Price | Best Use |
|---|---|---|---|
| Stock CPU | Level 1 | $45 | Early faulty-CPU swaps and starter builds |
| Mid-Range 6-Core CPU | Level 10+ | ~$180–$250 | Balanced mid-game builds and upgrades |
| High-End CPU (Overclockable) | Level 15 | $380 | Endgame builds and maximum benchmark scores |
The benchmark grades builds on part tier, compatibility, and balance. Pairing a flagship GPU with a Stock CPU drags the score down because the system penalizes unbalanced configurations — keep CPU and GPU tiers roughly even.
Match your CPU tier to the GPU tier whenever possible. Even mid-range pairings outscore a build with one flagship part and one budget part.
Troubleshooting Checklist
CPU Install Verification:
- Diagnostic scan confirmed the CPU before removal
- All screws removed before pulling the old CPU
- Replacement CPU tier matches the ticket requirement
- Power and cooler cables reconnected and fully seated
- Side panel screwed back on before benchmarking
- Benchmark passed before returning the PC to the customer
Common failure points and fixes:
| Problem | Likely Cause | Fix |
|---|---|---|
| CPU won't come out | Screws or cable still attached | Re-check all socket screws and connectors |
| New CPU won't register | Not fully screwed in | Re-seat and screw until the part locks |
| PC won't power on | PSU cable or switch | Connect PSU to motherboard, flip switch |
| Benchmark fails | Loose part or unbalanced build | Reseat CPU, check tier balance |
| Ticket won't complete | Wrong part tier installed | Compare installed parts against the ticket |
Complete small diagnostic jobs first or sell spare parts you've removed from earlier orders to fund replacement CPUs.
FAQ
Q: Can I install a CPU without the workbench in Fix PCs?
No. The workbench is the only place where you can open the build view, remove parts, and install replacements. Carry the customer's PC to the bench and press E to place it before attempting any CPU work.
Q: Which CPU should I use for early repair orders?
The Stock CPU ($45, Level 1) covers most early faulty-CPU swaps. Save mid-range and high-end CPUs for upgrade tickets and full builds that specifically request a higher tier.
Q: Why does my benchmark fail after installing a new CPU?
Usually a seating issue. Confirm every screw is fully tightened, all cables are reconnected, and the side panel is back on. If the build still fails, check that the CPU tier balances with the rest of the components — the benchmark penalizes unbalanced builds.
Q: Do I need to run the benchmark after every CPU install?
Yes. The benchmark is how the game verifies the repair before the customer accepts the PC. A passing score confirms the fix and unlocks your Cash payment; a failure means something is still loose or incorrect.
