Specifications

Processor, graphics and installed memory/storage describe the selected configuration. Expansion limits and connectivity describe the model; optional hardware is identified separately. References are collected in About this data below.

Processor: Intel Core i5-13500T
Graphics: Intel UHD Graphics 770
Memory: 16 GB
Storage: 512 GB
Ports & displays: Front: 2 × USB-A 10Gbps, USB-C 20Gbps and headset jack. Rear: 1 × USB-A 10Gbps and 2 × USB-A 5Gbps, 2 × DisplayPort 1.4 and HDMI 2.1 in the documented reference SKU. Additional Flex IO ports depend on the ordered configuration.
Ethernet, Wi-Fi & Bluetooth: Gigabit Ethernet (Intel I219-LM). Wireless is optional; HP platform documentation lists Intel AX211 Wi-Fi 6E / Bluetooth 5.3 and other card options. The reference SKU does not establish an installed wireless card.
RAM & storage upgrades: 2 × SO-DIMM, up to 64 GB. This reference SKU uses DDR4-3200; other G9 board versions use DDR5, so the types are not interchangeable. One M.2 2280 SSD slot and separate WLAN slot; the platform also supports a 2.5-inch SATA drive with a compatible carrier.
Power supply & power limits: 90 W external power adapter for the documented configuration; this is a rated output, not measured system power.
Dimensions & weight: 177 × 175 × 34 mm (W × D × H); reference configuration weight 1.42 kg.

HP Pro Mini 400 G9 Mini-PC review: NUC PC with good efficiency thanks to Intel Core i5-13500T and modular design

By Sebastian Bade · Notebookcheck

Source published: Jun 27, 2024
Test performed: Not reported by source
Added to MiniPC.guru: Sep 23, 2026
Source reviewed: Sep 23, 2026
Tested hardware: Intel Core i5-13500T, 14 cores / 20 threads (6 P + 8 E), socketed LGA1700; 74 W PL2 short burst and 35 W PL1 sustained, as the review's specification table prints them · Intel UHD Graphics 770, 1550 MHz, driver 31.0.101.5534 DCH (not used: this row renders on the processor) · 16 GB DDR4-3200 in a single SO-DIMM, single-channel · not applicable: a CPU render does not read from disk while the measurement runs; the unit carried an HP PSEJN512GA87EC0 of 512 GB
Software / version / OS: Blender · 2.79 · Microsoft Windows 11 Pro
Power profile: "HP Optimized" Windows energy profile, which the review says was used for all performance tests; HP offers no other performance modes. Limits 74 W PL2 / 35 W PL1
Test conditions: BMW27 standard demo scene, CPU render backend as the chart labels it ("Blender - v2.79 BMW27 CPU"). The review does not print samples or output resolution, so they are the ones stored in the standard scene file. Lower is better.

Editorial review checks the source and documentation; it does not certify the measurement or mean we tested the device ourselves.
