Power supply replacement in Watford: PC dead with no power?

Quick answer

PC dead with no power?

Power supply replacement in Watford diagnoses and replaces failing PSUs, the part behind more random shutdowns, restarts and dead machines than almost anything else in a gaming rig. It causes crashes under load, random restarts and faults that look like a graphics card or memory problem, which is why it should be tested first.

Quick checks before you call

  • Confirm the switch on the back of the unit is on
  • Try a known good kettle lead and a different wall socket
  • Note whether crashes only happen under heavy load
  • Listen for buzzing or clicking from the unit
  • Check the age of the unit, most are rated for around five to seven years

If you are unsure what is wrong, our specialists will diagnose it properly rather than guessing. You can also check the manufacturer support pages for known driver and firmware issues before you book, but if the fault is hardware we will find it and fix it.

“When a rig crashes under load and nobody can find the fault, the power supply is usually holding the answer.”

Power supply replacement: your questions answered

How do I know if my power supply is failing?

Random restarts, crashes only under load and a machine that will not power on at all are the classic signs. We bench test to confirm.

What wattage do I need?

It depends on your graphics card and processor. We calculate the real draw and add sensible headroom rather than overselling you.

Can a bad PSU damage other parts?

Yes. A unit without proper protection can take components with it when it fails, which is why we fit quality units only.

How long does a replacement take?

Many problems are fixed on the spot; some repairs need the workshop.

Why power supply replacement is worth doing right

The power supply feeds every other component. A cheap or failing unit puts the whole build at risk, including the graphics card.

Protect everything else

A quality unit with proper protection circuitry guards the parts that cost far more than it does.

Correctly rated

We size the replacement to your actual hardware plus headroom, not to a number on the box.

Stable under load

Clean, steady power stops the crashes and restarts that get blamed on drivers and games.
