Computer components covers the parts used to build, upgrade and repair desktop PCs and servers: mainboards, processors, graphics cards, memory, SSD and HDD storage, power supplies, cases and coolers. A large accessories section adds cables and adapters. Brands include Lenovo, Delock, InLine and HP Enterprise, so the range suits home builders, IT resellers and workshops.
How to choose computer components
Compatibility first. The processor socket must match the mainboard, and the mainboard decides which memory type, how many slots and which storage connections you can use. Check the chipset and the supported memory generation before you pick RAM or a CPU.
Storage type and purpose. SSDs suit operating systems, applications and anything that must load quickly. HDDs still make sense for bulk storage such as backups and archives, where capacity matters more than speed. Check whether your board has M.2 slots or only SATA ports. For servers and workstations with several drives, RAID and HBA controllers manage the disks and add ports.
Power supply and cooling. Add up the draw of the processor and graphics card, then leave headroom so the power supply does not run at its limit. For cooling, confirm that the cooler supports your socket and fits inside the case. Air coolers are simpler to fit, while water cooling parts are for builders who want to design a custom loop.
Case size and form factor. The case must take the mainboard size (ATX, micro-ATX or mini-ITX), the length of the graphics card and the height of the cooler. Also look at drive bays and front ports if you plan to add several drives or connect USB devices often.
Brands in our computer components range
- Lenovo: known for ThinkPad laptops and ThinkSystem servers, and the largest brand in this category, with many replacement and upgrade parts for its own systems.
- HP Enterprise and Dell: both are major server makers (ProLiant and PowerEdge), so their parts are most relevant if you maintain or expand business servers.
- Delock: a German brand known for cables, adapters and interface cards that connect or extend PC hardware.
- InLine: a German brand covering PC cables, adapters and accessories, along with cases and other everyday workshop parts.
- Alphacool: specialises in water cooling, with radiators, pumps, fittings and CPU and GPU blocks for custom loops.
- StarTech.com: known for connectivity products such as adapters, expansion cards, docking and cabling for office and server setups.
- Digitus: focuses on network and connection technology, including patch cables and cabling accessories.
- Wentronic: the maker behind the Goobay cable range, covering everyday cables, plugs and adapters.
Also in our range: Shiverpeaks, 2-Power and S-CONN Maximum Connectivity.
Within the category you will find subcategories for accessories, mainboards, coolers, cases, memory, HDD and SSD storage, power supplies, processors, graphics cards, RAID and HBA controllers, and optical drives.
Frequently asked questions about computer components
What components do I need to build a PC?
A working PC needs a processor, a mainboard, memory, a storage drive, a power supply and a case. A cooler is needed unless one comes with the processor. A separate graphics card is only required if the processor has no integrated graphics or if you want higher graphics performance.
How do I know if a mainboard and processor are compatible?
They must share the same socket, and the mainboard chipset must support that processor generation. The mainboard maker usually publishes a list of supported processors, and some older boards need a BIOS update to accept newer chips. Check this list before you buy.
Should I choose an SSD or an HDD?
Choose an SSD for the system drive and programs, because it starts and loads much faster. An HDD is better when you need a lot of storage for files you open less often. Many builders combine an SSD for the system with an HDD for archives.
How powerful should my power supply be?
It should cover the combined draw of the processor, graphics card and other parts with some headroom. The graphics card is usually the biggest consumer, so check the manufacturer's recommended power supply rating for it. A unit with spare capacity also copes better if you upgrade later.
