Is your desktop PC completely dead, failing to switch on or showing no signs of power when the power button is pressed?
A failed internal power supply unit (PSU) is one of the possible causes. Our PC power supply replacement service includes diagnosis and, where the PSU is confirmed as faulty, replacement with a new compatible power supply rated up to 500W.
The standard service costs £89.99 including the replacement PSU up to 500W. Gaming and higher-performance PCs requiring a more powerful or specialist PSU may cost more.
Common Symptoms of a Failed PC Power Supply
A faulty PSU can cause a range of power-related symptoms, including:
• PC completely dead
• No lights or fans
• No response from the power button
• PC powers briefly and immediately switches off
• Random shutdowns under load
• PSU fan not operating correctly
• Electrical smell from the power supply
• Computer becoming unreliable after a PSU failure
These symptoms do not automatically prove that the PSU is faulty, so the computer is checked before a replacement unit is fitted.
PC PSU Diagnosis
A desktop computer that appears completely dead can also have a motherboard short circuit, damaged power circuitry, faulty power button or another hardware problem.
Our engineers investigate the power fault and determine whether the PSU is responsible before replacing it.
This prevents an unnecessary replacement power supply being fitted when the actual fault is elsewhere in the computer.
What Is Included in the £89.99 PSU Replacement?
The standard service includes:
• Power fault diagnosis
• Removal of the faulty PSU
• New compatible power supply up to 500W
• Professional installation
• Connection of the required motherboard and device power cables
• Power and system testing
• 3-month warranty covering the original repaired fault
The replacement PSU is selected to provide the connections and specification required by the computer.
Gaming PCs and Power Supplies Above 500W
Gaming PCs and higher-performance desktop computers frequently use more powerful PSUs because dedicated graphics cards and other components can significantly increase power requirements.
Your computer may require a 600W, 750W, 850W or higher-rated unit depending on its hardware.
Higher-wattage and specialist power supplies vary considerably in price. If your PC requires a PSU above the standard 500W allowance, we will advise you of the additional cost before proceeding.
What if the PSU Failure Has Damaged Something Else?
Although many PSU failures are resolved simply by replacing the power supply, an electrical failure can sometimes be accompanied by damage elsewhere in the computer.
If testing identifies a separate motherboard, graphics-card, storage or other component fault, that additional repair is not automatically included in the standard PSU replacement price.
We will contact you and explain what has been found before carrying out any additional chargeable work.

PC Power Supply Replacement FAQs
How much is a PC power supply replacement?
Our standard PSU replacement costs £89.99 and includes a new compatible power supply up to 500W.
Is the replacement PSU included in the price?
Yes. A compatible new PSU up to 500W is included in the standard £89.99 service.
What if my gaming PC uses a 750W or 850W PSU?
Higher-wattage and specialist power supplies cost more. We will confirm the additional price before replacing the PSU.
Does a completely dead PC always mean the PSU has failed?
No. Motherboard and other electrical faults can cause similar symptoms, which is why the computer is diagnosed before a replacement PSU is fitted.
What happens if the motherboard is faulty instead?
We will contact you with the diagnosis and appropriate repair price before carrying out additional work.
Is the repair covered by warranty?
A successful PSU replacement carries our standard 3-month repair warranty covering the original repaired fault.
