Dell Desktop Repair — your questions answered
How much does it cost to replace a Dell OptiPlex power supply?
A standard 300 W to 460 W unit for OptiPlex 7010 through 9020 models typically ranges from $180 to $260 including labour. Technicians match the exact Dell part number for connector fit and 80 PLUS rating. Same-day service is common when the part is in stock.
Can you repair an Alienware Aurora that keeps overheating?
Yes. Common causes include failed AIO pumps, dried thermal paste or blocked radiators in R12 to R16 models. A full service includes pump testing, coolant top-up or replacement, and fresh paste on CPU and GPU. Turnaround is usually one business day.
Will you come to my home or office for a Dell desktop repair?
Our technicians provide onsite visits across major Australian cities and can also handle remote diagnostics or workshop repairs. You choose the option that suits your location and schedule. No fix, no fee applies to all visits.
How long does a Dell XPS desktop repair usually take?
Simple jobs such as RAM upgrades or SSD swaps are completed same day. More involved work like motherboard repairs or custom PSU replacements may take two to five business days depending on parts availability.
Do you still service older OptiPlex 7010 and 9020 towers?
We continue to support these models with power supply, capacitor, and drive replacements. Many parts remain available through Dell channels and third-party suppliers. A quick diagnostic determines whether repair is economical.
