The hardest part of a first Raspberry Pi project is usually not the project, it is getting four small details right before you ever write a line of code. Getting started with a Raspberry Pi 5 means pairing the board with the correct power supply, real cooling, and the right storage, then flashing an OS that the official tool makes almost foolproof. Get those essentials sorted and you are running a tiny Linux computer in under half an hour, ready for everything from a home server to a retro console.
Quick Answer
A working Raspberry Pi 5 setup needs four things: the board, a 27W USB-C Power Delivery supply, active cooling, and a microSD card or NVMe drive for the operating system. Flash Raspberry Pi OS with the official Imager, and a first-time setup takes under 30 minutes from box to desktop.
The Four Essentials You Cannot Skip
The Pi 5 is noticeably more powerful and more demanding than earlier boards, so the kit around it matters more than it used to.
Power: 27W USB-C PD
The Pi 5 expects a 27W USB-C Power Delivery supply. Underpowering it is the most common beginner mistake, leading to random reboots, throttling and corrupted storage. A phone charger that does not negotiate the right PD profile will leave the board starved, especially once you attach USB drives or accessories that draw their own power.
Cooling: make it active
Earlier Pis often ran fine bare. The Pi 5 runs hot enough under load that active cooling is effectively mandatory if you want sustained performance. The official active cooler or a case with a built-in fan keeps the chip from throttling during compiles, media transcoding or any continuous workload.
Storage: microSD or step up to NVMe
A good A2-rated microSD card is the simplest start. For anything you will use daily, a server, a desktop replacement, the Pi 5's support for NVMe via an adapter board transforms responsiveness. NVMe boots faster, handles databases better, and is far more durable than a card under constant writes.
The board itself
The 8GB model gives the most headroom for browsing, containers and multitasking, while 4GB is fine for focused single-purpose projects. Buy the RAM you need for where the project is going, not just where it starts.
Flashing the OS With Raspberry Pi Imager
The official Raspberry Pi Imager removes almost all the friction from first setup.
- Install Imager on your Windows, macOS or Linux machine and insert your microSD card or connect your NVMe drive.
- Click Choose Device and select Raspberry Pi 5.
- Click Choose OS and pick Raspberry Pi OS for a full desktop, or Raspberry Pi OS Lite for a headless server.
- Click Choose Storage and select your card or drive.
- Before writing, open the settings gear. This is the step beginners miss. Set the hostname, enable SSH, and preconfigure your Wi-Fi name and password plus your username here.
- Click Write and wait for the flash and verify to finish.
Preconfiguring SSH and Wi-Fi in step five means the Pi can join your network and accept a remote connection on first boot, so you can run it without ever attaching a monitor if you choose.
First Boot and First Projects
Insert the storage, connect power, and the Pi boots into either a desktop or, for Lite, a login prompt you reach over SSH. Run the system update commands to bring everything current, then you are ready to build.
Three projects suit a first board well. A Pi-hole turns the Pi into a network-wide ad and tracker blocker that benefits every device in the house. A simple home media or file server gives you network storage that sips power. A retro gaming setup is a fun way to learn the basics while ending up with something genuinely useful. Each teaches a different slice of Linux without overwhelming you.
Going Further: Intermediate Projects
Once you are comfortable with the basics, the Pi 5's power opens up more ambitious builds. Home Assistant is one of the most popular next steps: it is open-source smart-home software that connects to nearly every commercial smart-home device and lets you build automations locally without relying on cloud services. The Pi 5, particularly the 8GB model, runs it smoothly even with dozens of integrations active.
A personal VPN server using PiVPN is another strong second project. It lets you route traffic from your phone or laptop back through your home network when you are out, giving you a private tunnel without a subscription. Setup takes under an hour and is well documented.
For makers with a coding focus, the Pi 5 is a capable lightweight development machine. Its PCIe-backed NVMe storage means compiling projects, running local Git servers or testing Docker containers is far quicker than on older boards. If your project grows beyond what a Pi comfortably handles, a heavier home server or always-on desktop becomes the logical next step, and the compact mini PC range at Evetech shows the options once you want more storage and horsepower in the same small footprint. For inspiration on full small-form-factor builds that local makers are running as home labs, scanning the systems other buyers are putting together right now helps you picture where a first Pi can lead.
Frequently Asked Questions
What power supply does a Raspberry Pi 5 need?
A 27W USB-C Power Delivery supply. Anything weaker risks reboots, throttling and storage corruption, especially once you add USB peripherals. This is the single most important accessory to get right.
Do I really need active cooling on a Pi 5?
For any sustained workload, yes. The Pi 5 throttles under load without a fan or active cooler, so a case with cooling or the official active cooler is worth treating as essential rather than optional.
Should I use a microSD card or NVMe?
A microSD card is the easiest start and fine for light projects. For daily-use servers or a desktop replacement, NVMe via an adapter is far faster and far more durable under constant writes, so step up to it if the project is permanent.
Can I set up a Raspberry Pi without a monitor?
Yes. In Raspberry Pi Imager, open the settings gear before writing and enable SSH plus your Wi-Fi details. The Pi then joins your network on first boot and you connect over SSH, no monitor or keyboard required.
Which Raspberry Pi OS version should I pick?
Choose the full Raspberry Pi OS if you want a graphical desktop. Choose Raspberry Pi OS Lite for headless servers, since it skips the desktop and uses fewer resources, leaving more for your actual project.
What should my second Pi project be?
Home Assistant for smart-home automation or PiVPN for a personal VPN are both strong choices. Both are well documented, reward the Pi's always-on nature, and teach you a different set of Linux and networking skills compared to a simple file server or Pi-hole.
