Neco 2022 Computer Studies Question 36
Practice objective / multiple choice question 36 from the 2022 Neco Computer Studies examination.
A desktop computer uses a 500 W power‑supply unit (PSU) that operates at 85 % efficiency when the load is at 50 % of its rated capacity. The computer's components draw the following power: CPU = 95 W, GPU = 150 W, hard‑disk = 10 W, solid‑state‑drive = 5 W, and two case fans each consuming 3 W. Assuming the PSU can deliver its rated output power (500 W) to the components, what is the greatest total power (in watts) that can be added for additional peripherals without exceeding the PSU's capacity?
