Quick answer: Start with compatibility: match a PSU's wattage and connectors to your graphics card (an 80 PLUS Gold ATX 3.0 unit of about 750 W suits most mid-range gaming PCs), a dock's ports to your laptop's USB-C or Thunderbolt support, and a monitor arm's VESA pattern and weight rating to your screens. Then compare warranty and cable length.

Frequently asked questions (2026)

What wattage PSU do I need?

Add up your CPU and GPU power draw and allow headroom. Many mid-range gaming PCs suit a quality 650-750 W unit; high-end GPUs may need more.

Will a USB-C dock work with my laptop?

Only if your laptop's USB-C port supports video output (DisplayPort Alt Mode or Thunderbolt). Check your laptop's specs and the dock's requirements.

How do I know if a monitor arm fits my screen?

Check the monitor's VESA pattern (usually 75 x 75 or 100 x 100 mm) and weight against the arm's ratings.

Where should I put a Wi-Fi range extender?

About halfway between your router and the area with weak signal, where it still gets a strong connection from the router.
