Starting with a Raspberry Pi 5 means sourcing the board, a 27W USB-C PD power supply, the Active Cooler, a case and either a microSD or NVMe SSD for storage. Getting every component right upfront avoids common bottlenecks that slow your first boot.
A bare Raspberry Pi 5 board is not a computer yet. It is the centrepiece of a small shopping list, and getting that list right upfront is the difference between a Pi that boots fast and runs cool and one that throttles, corrupts its storage or refuses to power on at all. The board changed enough between generations that old accessories no longer cut it, so the checklist matters more than it used to.
To start with a Raspberry Pi 5 you need five things: the board, a 27W USB-C Power Delivery supply, the official Active Cooler, a case, and storage that is either a quality A2-rated microSD card or an NVMe SSD on a HAT. Budget for all five together, because the power supply and cooler are not optional extras on a Pi 5.
Choose your RAM at purchase, because it is soldered and cannot be upgraded later. For general tinkering, a media box or light desktop use, the mid-tier RAM option is plenty. If you plan to self-host several services, run containers or use it as a small desktop with many browser tabs, step up to the largest RAM variant. This is a decide-once choice, so lean toward more memory if your plans are open-ended. The Pi 5 is available in 2GB, 4GB, 8GB and 16GB configurations; for most people 4GB or 8GB is the sensible starting point.
The Pi 5 draws meaningfully more power than earlier boards and officially expects 5V at 5A, which is why the official supply is rated at 27W to give headroom. A phone charger or an old Pi 4 supply will leave the board undervolted, and an undervolted Pi 5 throttles, restricts the power available to USB devices, or simply will not boot. This is the single most common first-time mistake. Buy a 27W USB-C Power Delivery supply and treat it as part of the board, not an accessory.
The Pi 5 runs hot enough that it will throttle under sustained load without active cooling. Without any cooling it can hit 85 degrees Celsius within 90 seconds of a heavy workload and drop from 2.4GHz to around 1.8GHz. The official Active Cooler is a heatsink and small blower fan that clips straight onto the board with no tools and plugs into the fan header, where the operating system controls its speed automatically. With it fitted, temperatures stay below 55 degrees Celsius at typical room temperature and the board sustains full clock speed indefinitely. For anything beyond the lightest use, fit one from the start.
A case keeps dust off the board, protects the exposed components and gives the Pi a tidy home on your desk. The official case is designed around the Pi 5's footprint and includes its own thermal provisions, but plenty of third-party cases exist if you need extra ports, a specific look or room for an NVMe HAT. Whatever you pick, make sure it has space for your chosen cooling solution, because a cramped case that blocks the Active Cooler defeats the point.
You have two real paths. A quality A2-rated microSD card of at least 32GB, pre-loaded or flashed with Raspberry Pi OS, is the cheapest and simplest start and is fine for most projects. The better experience comes from an NVMe SSD: the Pi 5's PCIe 2.0 port lets you attach a drive through an NVMe HAT and reach sequential speeds in the 400 to 500 MB/s range, far quicker and far more durable than a card. If the Pi will see constant writes, as a server or always-on host does, NVMe is well worth the extra outlay.
The Raspberry Pi 5 runs Raspberry Pi OS as its primary supported system, though Ubuntu and other Linux distributions offer Pi 5 builds. The recommended setup route is to use the Raspberry Pi Imager tool on a PC or Mac: select your OS, write it to your microSD card or NVMe drive, and configure Wi-Fi and SSH credentials before the card enters the board. That way the Pi comes up headless on first boot, already on your network, with no monitor needed.
If you are booting from NVMe, you need to boot once from microSD first to update the bootloader firmware and enable PCIe NVMe boot. This is a one-time ten-minute step well covered in the official documentation, after which the board boots directly from the NVMe drive every time.
Order the board, the 27W supply and the Active Cooler as your non-negotiable core, add a case that fits your cooler and any HAT, then choose microSD for simplicity or NVMe for speed and longevity. A micro-HDMI to HDMI cable, a keyboard and mouse round out a desktop setup, though a headless server needs none of those once it is on your network. If your project is really about a compact always-on machine rather than tinkering with GPIO pins, it is worth checking the Evetech mini PC category to see how ready-built compact machines compare, and viewing what other SA buyers are picking up helps illustrate where a small desktop might serve you better than a Pi for everyday computing.
Not reliably. The Pi 5 expects up to 5A and the official 27W supply provides the necessary headroom. An older or weaker supply causes undervoltage warnings, throttling, reduced USB power and sometimes failure to boot. Use a proper 27W USB-C PD supply.
For all but the lightest, occasional use, yes. The Pi 5 throttles under sustained load without active cooling, which kills performance. The official Active Cooler is inexpensive, clips on without tools and keeps the board running at full speed.
A good A2-rated microSD card is the simplest, cheapest start and suits most projects. An NVMe SSD on a HAT is faster and far more durable, which matters for always-on servers or anything that writes constantly. Choose NVMe if your workload is write-heavy.
At least 32GB is the sensible minimum for the operating system plus room for software and files. A2-rated cards handle the small random reads and writes of an operating system far better than basic cards, so prioritise the A2 rating over raw capacity.
The board on its own includes only the board. The power supply, cooler, case and storage are all separate purchases, which is exactly why a checklist matters. Starter kits bundle these together if you would rather buy everything in one go.
If your goal is a small, always-on machine rather than a hobby board, it is worth weighing the Pi against a ready-to-run alternative. Compare the mini PC range at Evetech to see which fits your project best: https://www.evetech.co.za/PC-Components/mini-pcs-194
