Redragon MPC745 Mini PC: problems, parts and running costs

Checked: 2026-10-28

Summary

The MPC745’s practical problems are documentary rather than mechanical: the installed SSD is PCIe 3.0 even though earlier marketing said PCIe 4.0, the product page says “Linux or Ubuntu (Pre-installed)” without confirming a Windows license, and warranty terms differ between the product page and the shop policy. It suits an office, development or media desk where a 0.5-liter box is enough, but not a discrete-GPU gaming machine. It is a strong buy at $400 to $450 with a valid operating system and a working return policy.

Common problems and fixes

SSD generation does not match earlier marketing — one buyer reported a PCIe 3.0 SSD in a machine earlier advertised as PCIe 4.0, and the present product text states PCIe 3.0 twice. There is no fix; treat the current listing as the specification and confirm the drive with the seller before checkout. A documented specification mismatch is a seller question rather than a warranty repair. [1][3]
One owner reports 512MB of reserved graphics memory and game crashes — the Radeon 780M shares system RAM dynamically, so a reported 512MB preallocated buffer is not proof that the GPU can access only 512MB. No reproduced failure and no tested BIOS fix were located, so the sensible response is to check BIOS options and error logs for the specific unit; no multi-sample finding supports claiming a general defect. [1][2]
Warranty length is stated inconsistently — the product page says “Warranty 1-year” while the shop’s general policy says 2 years for new products bought there, and another Redragon domain states 1 year. Get written confirmation of the coverage on an MPC745 order and keep the invoice; the shop policy covers manufacturing defects and excludes owner damage, modifications, misuse and normal depreciation. [1][7][8][14][15]
Availability is thin — the manufacturer’s own page was sold out and the Newegg individual listing showed out of stock in October 2026. There is no fix, only timing; treat an in-stock seller as part of the purchase decision. [1][4]
Shared memory limits headroom — the installed 16GB is split between CPU work and integrated graphics, and the manufacturer caps memory at 32GB. Upgrading to 32GB is the documented remedy for memory-hungry multitasking or games, but it costs money and means opening the case. [1][2]

Parts and consumables

Consumables — no ink, filter, licensed monthly software or proprietary service supplies apply, and no verified annual costs were found. [1]

Yearly running cost

No product subscription or periodic consumable spending is listed. Electricity depends on workload and on whether the unit is left running or asleep. The CPU’s 45W rating is a thermal design figure, not a measured wall draw, so a verified annual bill cannot be computed from the sources. As an illustration only, assuming 40W at the wall for 4 h/day and 8W for another 20 h/day gives 116.8 kWh a year, or $23.36 at an assumed $0.20/kWh; monitors, an external GPU and other peripherals are excluded, and the 40W and 8W values are examples rather than observations of this machine. Repairs and upgrades have no supported annual estimate, since RAM, SSD, fan and adapter intervals and costs were not established. [1][2][8]

When it is a good buy

The manufacturer’s own listing showed $609.99 and marked sold out in October 2026, with a 15% GHOST15 code displayed on the page, and a shop app storefront also showed $609.99 in October 2026; neither establishes a completed sale while stock is out. A cached Newegg sale-category result showed $549.99 with an extra $51 conditional promo in June 2026, a community promotion recorded a $394.57 offer on June 3, 2026 that has since expired, and the September 2025 launch price was $499.99. An open-box manufacturer outlet page displayed $99.99 but sold out, final sale, with a six-month warranty and US shipping only, so it is not a usable market reference. On that basis $400 to $450 with a valid OS, a return policy and tested functions is a strong purchase, $451 to $500 is reasonable when the USB4 and 2.5Gb Ethernet combination matters, $501 to $550 calls for comparing better-supported or 32GB models or waiting for a sale, and above $550 the limited RAM, unknown OS entitlement and weak exact-model testing make list price hard to justify. The alternatives are the GMKtec NucBox K8 Plus, listed at $919.99 configured with 32GB RAM and 1TB SSD or $399.99 barebone, which suits DIY and eGPU buyers; the MINISFORUM UM880 Plus, listed at $351 barebone or $869 configured with 32GB RAM and 1TB SSD, which suits buyers who want expandable storage and a documented two-year warranty; and the Beelink SER8, listed at $799 with 24GB DDR5 and 1TB SSD, which suits buyers who prefer a more established premium mini-PC design.
