HP 27 All-in-One PC

This HP 27 All-in-One PC integrates a 27 inch IPS touchscreen with a 15th Gen Intel Core Ultra 7-255U processor. It ships with 16GB DDR5 memory and a 1TB PCIe NVMe SSD running Windows 11 Home. The system targets home and office users who want a compact desktop with touch input and included wireless peripherals.

90W power supply and integrated graphics

The 90W power supply feeds the Ultra 7-255U with its 12 cores and 14 threads alongside Intel integrated graphics. Thermal output stays modest during typical productivity workloads such as web browsing, document editing and video playback. Fan noise remains low in normal use because the integrated GPU avoids the heat of a discrete card.

Shell White finish with wireless kit

The Shell White chassis measures 20.25 by 24.25 by 7.4 inches and weighs 14.5 pounds, so it sits stably on a desk without a separate tower. Connectivity includes two USB 2.0 ports, one HDMI output, one USB 3.2 Type-C port and a headphone/microphone combo jack. A bundled Dockztorm USB hub adds extra ports for day-to-day accessory expansion.

Questions about this item

How do I set up the wireless keyboard and mouse that come in the box, and what step do people skip?

Insert the USB receiver into the USB 3.2 Type-C or USB 2.0 port, then turn on the keyboard and mouse power switches; the step most people skip is installing fresh AA or AAA batteries before pairing.

Which component will need replacement first, and what specification must the new module match?

The 16GB DDR5 SO-DIMM is the only user-replaceable memory; any upgrade must be a DDR5 SO-DIMM module to fit the slot.

At what sustained workload does the 90W power supply become the limiting factor?

Continuous all-core turbo at 5.2 GHz on the Ultra 7-255U can draw enough power that the 90W PSU caps performance before thermals do.
