HP ProDesk 600 G6 Microtower: problems, parts and running costs

Checked: 2026-10-18

Summary

What usually goes wrong is not a breakdown but the seller-installed GT 610 graphics card, which drives the displays in this configuration and is too weak for anything but basic output, and HP’s proprietary power supply and chassis connectors, which make upgrades harder than on a generic tower. It costs nothing per year to run — no consumables, no subscriptions — though buyers should budget for a graphics card, memory or SSD upgrade. It is a good buy on the used market at the $400-425 refurbisher-quote level, and a poor pick for gaming or GPU-heavy work while the GT 610 is in place.

Common problems and fixes

GT 610 graphics too weak — the i5-10400F plus GT 610 combination is not a standard HP retail SKU; no HP documentation of a GT 610 configuration was found and the card is treated as seller-installed, a 2012-era part kept in service for basic display output. Replace it for any gaming or GPU-accelerated work; the refurbisher’s warranty terms are not documented in the sources. [1]
No usable video without the discrete card — the i5-10400F has no integrated graphics, so the motherboard’s two DisplayPort 1.4 outputs do not work in this configuration and video depends entirely on the graphics card. Keep a working discrete card installed at all times. [1]
Proprietary power supply and chassis complicate upgrades — HP uses proprietary PSU, chassis and power-connector elements, and the stock PSU may lack the PCIe power connectors a graphics card needs. Check which PSU the unit carries — 180, 260 or 550 W depending on configuration — before planning a GPU swap. [1]
Short refurbisher warranty — Micro Center sells refurbished ProDesk 600 G6 units with a 90-day limited warranty, parts and labor, against the 3-year limited warranty on HP’s retail Microtower. Budget for a potential PSU or GPU replacement outside the warranty window. [3][4][2]
Dated 2020 platform — 10th-generation Core on the Q470 chipset handles office work, home servers and virtualization but is old for heavy CPU work. No fix; buy this machine for the upgrade ceiling, not raw speed. [1]
Wi-Fi may be missing — Wi-Fi/BT is not always included; the M.2 2230 slot takes a combo card that may need separate installation. HP’s retail Microtower configuration includes Wi-Fi 6; check the listing before assuming wireless. [1][2]
No HDMI on the motherboard — the board offers DisplayPort 1.4 only; in this configuration HDMI comes from the graphics card. Use DisplayPort, or plan around the card’s outputs. [1][2]

Parts and consumables

No part prices are documented in the inputs; these are the parts owners deal with on this platform, with what the sources say about each.

Graphics card (NVIDIA GeForce GT 610 1GB) — seller-installed, not a documented HP option; the first part to replace for any gaming or GPU-accelerated work. A GPU upgrade fits the PCIe x16 slot on the 550 W PSU but may need SATA-to-PCIe power adapters. [1]
DDR4 memory — four DIMM slots, up to 128GB, standard parts; the platform officially supports up to 2666 MT/s. [1]
Storage (M.2 NVMe and SATA) — two M.2 slots (one PCIe x4 NVMe, one 2230 for Wi-Fi/BT) plus four SATA ports; this configuration carries a 512GB NVMe SSD. [1]
M.2 2230 Wi-Fi/BT combo card — needed if the unit ships without wireless. [1]
Power supply (180, 260 or 550 W options) — proprietary HP unit; swaps are limited by HP’s chassis and power connectors. HP’s retail Microtower ships with a 180 W unit. [1][2]

Yearly running cost

Not enough data. There are no consumables and no subscriptions; the only recurring cost is electricity, which the sources do not quantify, plus any one-off RAM, SSD or GPU upgrade. A typical owner’s recurring yearly cost is $0.

When it is a good buy

Micro Center lists a refurbished ProDesk 600 G6 (i7-10700, 16GB, 1TB, UHD 630, Windows 11 Pro) at $499.99 in-store with a 90-day limited warranty (October 2026). [3]
A Reddit user in r/HomeServer reports a refurbisher quoting about $400-425 for an i5-10500, 64GB, 1TB configuration with no OS. [5]
A Reddit user in r/homelab reports a G6 Mini working as a Proxmox node for $197. [6]
HP’s retail Microtower configuration at B&H Photo (i5-10500, 16GB, 512GB M.2 SSD, UHD 630, 180 W PSU, Wi-Fi 6, 3-year limited warranty, computer and power cable only) is the better choice when you want HP’s own warranty and no seller-installed graphics card. [2]
