Frequently Asked Questions

How do I know if my power supply is the issue?

If your computer doesn’t power on, shuts down randomly, or emits burning smells or clicking noises, the PSU is likely faulty. Our technicians will perform diagnostics to confirm.

How much does it cost to replace a PSU?

Costs vary based on the type (standard desktop, gaming, or laptop PSU) and wattage. At Canberra Computer Repairs, we offer competitive pricing and upfront quotes before any work begins.

Can you repair laptop charging ports?

Yes! We can fix or replace damaged DC jacks and internal charging circuits, which are often mistaken for power supply issues in laptops.

Do you offer same-day repairs?

In many cases, yes. If the required parts are in stock and diagnostics are quick, we can often complete the job the same day.

Will a power supply replacement fix random restarts?

It depends. While a faulty PSU can cause restarts, we also check for overheating, RAM errors, and motherboard faults. Our diagnostics cover the full system.

Do you provide warranty for PSU replacements?

Yes, all parts we purchase come with full manufacturer’s warranty (warranty periods vary depending on the brand/part).
