HP Omen Obelisk 875 Repair — your questions answered
How much does it cost to repair an HP Omen Obelisk 875 that won’t turn on?
Power issues on the 875 are usually the 750 W modular PSU or swollen motherboard capacitors. A new PSU starts around $220 while capacitor work is $280-$420. We test both before quoting and only charge if we fix it.
Can you recover data from a failed SSD in an HP Omen Obelisk 875?
Yes. We image the original NVMe drive in our clean room, transfer the data to a new 1 TB or 2 TB SSD, then reinstall Windows. Pricing for recovery plus the new drive is typically $260-$390.
Is it worth upgrading RAM and storage in an older Omen Obelisk 875?
Adding 32 GB DDR4-3200 and a modern PCIe SSD makes the machine feel current for everyday and light gaming use. Combined cost is usually $300-$400 and extends usable life by several years.
How long does a typical HP Omen Obelisk 875 repair take?
Most jobs—PSU swaps, RAM upgrades, SSD clones—are completed same or next day. Capacitor-level motherboard work or complex data recovery can take two to three days.
Do you come to my home or do I have to bring the desktop in?
We offer onsite visits across capital cities, remote diagnostics Australia-wide, or you can drop the tower at our workshop. Choose whichever suits you when you book.
