Tower desktop for home users

The Lenovo IdeaCentre Tower 14IRR9 is a cloud-grey desktop PC built around an Intel Core i5-14400 10-core processor with 20 MB L3 cache and a 4.7 GHz maximum turbo frequency. It ships with 16 GB of DDR5 4800 memory in one of two DIMM slots, leaving room for expansion up to 32 GB. A 512 GB NVMe PCIe 4.0 x4 SSD provides the primary storage, and a DVD±RW optical drive is included. Integrated Intel UHD Graphics 730 drives HDMI 2.1 and VGA outputs. Windows 11 Home is pre-installed.

260 W PSU with integrated graphics

The system draws power from a 260 W supply rated at 90 per cent efficiency. With the Intel UHD Graphics 730 integrated into the processor, there is no discrete graphics card to add heat or fan noise under typical workloads. Wi-Fi and Bluetooth 5.3 handle wireless connectivity, while a front USB-C port delivers 5 Gbps data and 15 W charging. A USB keyboard and mouse are included in the box.

Expandable DDR5 memory to 32 GB

The motherboard provides two DDR5 DIMM slots with one currently occupied, so the memory ceiling is 32 GB. Buyers who need more than 32 GB of RAM should look elsewhere, as the chipset and slot count do not support larger configurations.

Questions about this item

How do I install extra DDR5 memory in the two DIMM slots, and which step do people often miss?

Open the tower, align the notch on the DDR5 module with the slot key, press firmly until both side clips click, then power on and verify 32 GB in BIOS — the step most people miss is seating the module fully so both clips engage automatically.

What maintenance or replacement will the 260 W power supply need later?

The 260 W unit has no user-serviceable parts; plan to replace the entire PSU if fan noise increases or voltages drift, and keep the replacement at 260 W or higher with the same connector layout.

What limit appears first when the Core i5-14400 runs at 4.7 GHz turbo for long periods?

The 260 W power supply caps total system draw, so sustained 4.7 GHz turbo on all 10 cores will hit the PSU limit before the CPU thermal throttle engages.
