The GMKtec M5 Ultra is a mini PC roughly the size of a hardcover book. Inside is an AMD Ryzen 7 7730U, an 8-core, 16-thread processor with integrated Radeon graphics. RAM starts at 16GB of DDR4 with an open slot for a second stick, and storage runs on a 512GB PCIe SSD with a second M.2 bay open for expansion up to 8TB. Windows 11 Pro comes preinstalled.
The GMKtec M5 Ultra Gaming Mini PC is currently $400 on Amazon, down from $500, for a 20% discount.
A mini gaming PC that’s perfect for setting up a gaming area in a small space
Desktop towers eat up a lot of space, either under the desk or sitting on top of it. The M5 Ultra measures under 5 inches on a side and weighs under a pound, which changes the calculus for where a PC can go. Bolt it to the back of a monitor with the VESA mount that ships in the box. Tuck it next to a receiver in a media cabinet. Set it on a bookshelf. A mini PC makes sense for studio apartments, dorm rooms, and shared home offices. All the M5 Ultra needs is an outlet, a monitor, and about 5 inches of shelf or desk space to work.
The back of the M5 Ultra has three video outputs: HDMI 2.0, DisplayPort, and USB-C. HDMI runs 4K at 60Hz; DisplayPort supports 4K at 144Hz or 8K at 60Hz; and the USB-C port doubles as another DisplayPort output. Triple-monitor setups run natively without a dock or splitter. Two 2.5GbE Ethernet ports on the back also give the M5 Ultra network options most consumer PCs skip, useful for splitting a home network between subnets or setting the M5 Ultra up as a small home server.
Opening the M5 Ultra requires removing four screws from the bottom panel. Inside are two SO-DIMM slots for DDR4 RAM, expandable to 64GB total, and two M.2 2280 SSD slots supporting up to 8TB combined on PCIe 3.0. The 16GB and 512GB configurations that the M5 Ultra ships with handle most casual computing, and upgrading later takes about 5 minutes with a Phillips-head screwdriver.
GMKtec has spent the past few years building a name for itself in the mini PC space, with the M-series covering a range of price and performance tiers. At $400, down from $500, the M5 Ultra hits the price where a mini PC starts making real sense over a tower. Whether it’s for a home office short on desk space, a media room where a tower doesn’t fit, or a family room PC that has to disappear into the shelves, this is where the M5 Ultra lands.
