Quick Answer

For first-time builders, USB-C power delivery on a dock is worth paying for only if you also run a USB-C laptop alongside the new tower; a desktop draws power from its own PSU, not the dock. If a laptop shares the desk, an 80W-plus PD dock around R1,700 charges it on one cable.

When PD Helps A First Build

A desktop does not need a dock for power, so PD matters here only when a laptop joins the setup, which is common: a student or worker with a build for gaming and a laptop for class or the office. A PD dock then charges and connects the laptop in one move, while the desktop uses the dock's USB and display passthrough for shared peripherals or a second screen.

If a laptop and the new tower will share the desk, run the dock's single cable to the laptop and keep the desktop on its own ports, so one connection charges and links the laptop while the build draws all the power it needs straight from its own PSU.

When To Skip PD On A Build Dock

If the dock will only ever serve the desktop, skip power delivery and buy a cheaper data-and-display dock; the tower charges nothing through it. Spend the difference on a fast 10Gbps USB-C port for external NVMe storage instead, which a builder is far more likely to use than charging that the PSU already handles.

FAQ

Does my desktop need a dock with power delivery?

No; the desktop powers itself from its PSU. PD on a dock only matters if a USB-C laptop shares the same desk and needs charging.

What wattage PD should I get for a shared laptop?

Match the laptop's own charger, typically 65W to 100W. An 80W-plus dock covers most laptops while you connect peripherals to the tower too.

What should a desktop-only dock prioritise instead of PD?

A fast 10Gbps USB-C port for external NVMe storage and reliable display passthrough, since those serve a builder more than charging the PSU already provides.

TIP

for power delivery if a USB-C laptop shares the desk; for a desktop-only dock, put the money into a fast 10Gbps port instead.
