HP ProDesk 600 G3 Repair — your questions answered

How much does it cost to repair a HP ProDesk 600 G3 that won't turn on?

A no-power fault is usually the internal PSU. We test the 12 V rail first; if the PSU has failed we fit a matched 180 W or 250 W replacement for $145-$195 including labour and a 90-day warranty.

Can you upgrade my HP ProDesk 600 G3 to Windows 11?

Yes. After confirming the 7th-gen Intel CPU meets TPM 2.0 requirements we install a clean Windows 11 image, add an SSD and up to 32 GB DDR4 RAM so the machine runs smoothly and remains supported.

Is it worth repairing an old HP ProDesk 600 G3 or should I buy new?

For typical office use a $180-$260 SSD and RAM upgrade plus any PSU or capacitor work often gives another three to five years of reliable service at a fraction of the cost of a new desktop.

How long does an SSD upgrade take on the HP ProDesk 600 G3?

We clone your existing drive to a new SATA SSD in one to two hours, then reinstall Windows and your programs so you can collect the machine the same day or have it returned by courier.
