5 Tools for PC Building Enthusiasts
1. PC Builder
PC Builder is probably our go-to tool for compatibility checking, and honestly, it should be yours, too.
PC Builder is like having a knowledgeable friend who knows every component and its compatibility quirks. What we appreciate about this platform is that it’s designed specifically for beginners who want to avoid compatibility issues – something that even experienced builders can struggle with when trying new hardware combinations.
What makes it special:
- Real-time compatibility checking as you add components
- Compatibility errors when components aren’t compatible
- Pre-builts for different budgets and use cases
We start every new build here, even if we’re pretty sure about compatibility. It’s saved us from ordering incompatible products more times than we’d like to admit!
2. Geekbench 6
Once your PC is built, you need to know if it’s performing as expected. Geekbench 6 is our preferred benchmarking tool for exactly this reason.
Why we recommend it:
- Standardized testing across different hardware configurations
- Both single-core and multi-core performance metrics
- Easy comparison with similar hardware setups
- Cross-platform compatibility (Windows, macOS, Linux)
It is always recommended to get a Geekbench run within the first 24 hours of your PC build. It will help you identify potential thermal throttling, memory issues, or underperforming components before they become bigger problems.
3. How Many FPS
Gaming performance prediction has never been easier, and honestly, this tool is a lifesaver for anyone building gaming rigs.
This tool answers the most common question we get: “Will this setup run games smoothly?” Instead of guessing or diving into dozens of YouTube reviews, this website gives us data-driven predictions based on your exact hardware combination.
What makes it an invaluable tool?
- Game-specific performance predictions
- Different resolution and quality settings
- Hardware upgrade impact analysis
- Regularly updated game database
We use this extensively when building gaming PCs for friends and clients. Instead of promising “it should run everything fine,” we can show exact FPS predictions for their favorite games.
4. Crucial System Scanner
Memory and storage upgrades can be tricky, especially with older systems or pre-built PCs where specifications aren’t always clear.
Crucial’s System Scanner tool eliminates all guesswork when it comes to memory and storage compatibility. It scans your system (or lets you input your motherboard model) and shows exactly what memory configurations will work.
Key benefits:
- Identifies current RAM configuration and available slots
- Shows maximum supported capacity and speed
- Suggests compatible SSD/NVMe drives
- Often includes current pricing and deals
We consistently rely on this tool for upgrade consultations. Instead of manually checking motherboard QVL lists or memory support pages, this tool gives us definitive answers in seconds.
It’s particularly useful for older systems where finding compatible high-speed memory can be challenging.
5. Power Supply Calculator by BuildMyPC
Choosing the wrong power supply is probably the most expensive mistake you can make in PC building. Either you over-spend on unnecessary wattage, or worse, you underpower your system and face stability issues.
BuildMyPC’s PSU calculator is an incredibly detailed tool that gives you all the information about the wattage needed. This will help you understand your system’s power needs and make better decisions about efficiency and upgrades.
What sets it apart:
- Accounts for overclocking scenarios
- Suggests PSU models with better efficiency ratings
- Includes safety margins in calculations
Something to note: The recommended wattages always leave enough headroom for minor upgrades without requiring a PSU swap.
Summing Up!
These five tools have saved us so much time and money over the years, and we honestly can’t recommend them enough.
The reality is simple – PC building is way easier when you have the right tools. Instead of guessing compatibility or power requirements, these tools give you exact answers in seconds.
Our advice: Bookmark all five of these right now. Seriously, create a “PC Tools” folder and keep them handy. Whether you’re planning your first build or your tenth, you’ll use these constantly. And the best part? They’re all completely free. There’s no reason not to use them, and they’ll definitely save you from expensive mistakes.
Happy building!
