ZOTAC ZBOX MAGNUS ONE ULTRA EU275080C — Barebone Gaming Mini PC
GeForce RTX 5080 16 GBCore Ultra 7 265Wi-Fi 7 · BT 5.4Barebone — add RAM & SSD
The ZOTAC ZBOX MAGNUS ONE ULTRA EU275080C is a small form factor gaming PC that pairs a desktop Intel Core Ultra 7 265 (20 cores, 2.4 up to 5.3 GHz) with a ZOTAC GAMING GeForce RTX 5080 graphics card with 16 GB GDDR7. It is sold as a barebone: the case, motherboard, processor, graphics, cooling and built-in 850 W power supply are there, but you add the memory, the SSD and the operating system. At 365.5 × 126 × 249 mm it is a slim tower of about 11.5 litres, with a full-size graphics card, two M.2 slots (one PCIe 5.0), a UHS-II SD reader and a Thunderbolt 4 port. Networking is 1 × Gigabit + 1 × 5 Gb Ethernet, Wi-Fi 7 and Bluetooth 5.4, and the graphics drive up to four cloned or six extended displays over DisplayPort 2.1 and HDMI 2.1b. In practice it gives desktop-class gaming and creative performance in a box that fits on a desk or TV unit.
Compatibility — check before buying:
Barebone: no memory, no SSD, no operating system. It needs laptop-size DDR5 memory (DDR5-6400 CSODIMM or DDR5-5600 SO-DIMM) — desktop DIMMs do not fit — plus an M.2 NVMe SSD and a Windows licence. The power cord in the box depends on the sales region, so ask us and we confirm the plug for Cyprus. There is no 2.5-inch drive bay in this ULTRA model. Do not confuse it with the MAGNUS ONE EU27507TC (RTX 5070 Ti, 650 W, smaller case). Tell us what you want to run and we suggest memory, SSD and setup.

Frequently Asked Questions
What do I need to add?
Laptop-size DDR5 memory (DDR5-6400 CSODIMM or DDR5-5600 SO-DIMM; two modules, up to 96 GB), one or two M.2 NVMe SSDs, and Windows. There is no 2.5-inch bay.
Can it run the latest games?
Yes. The RTX 5080 with 16 GB is aimed at 4K and high-refresh 1440p gaming with DLSS and ray tracing.
What is the difference to its siblings?
The MAGNUS ONE EU27507TC uses a smaller case with an RTX 5070 Ti and 650 W PSU; the ER98N5070C uses an AMD Ryzen 9 and RTX 5070.
Can it be mounted?
No. The MAGNUS ONE is a desktop small form factor PC with no wall or VESA mounting; it stands on a desk or in a TV unit with space for airflow.
Singular Expert Insight
We suggest the EU275080C when you want RTX 5080 performance without a full tower: it is the most powerful ZBOX in this batch. Use two DDR5 modules for dual channel and a PCIe 5.0 SSD in the fast slot. Pick your parts from our
memory (RAM) and
internal SSDs, and we can assemble and install it for you.
