ASUS ROG NUC RNUC15JNK9X28AAU Black 2025

The ROG NUC packs an RTX 5080 and 24-core Core Ultra 9 into a 3.12kg mini PC, with CPU, GPU, RAM, and storage all ranking in the 91st to 92nd percentile. It's the fastest mini PC in our database, full stop. But reliability sits at a mediocre 36th percentile and prices swing by $488 between vendors, so shop carefully.

The RTX 5080 with 16GB of VRAM is the headline act here. That's a mobile GPU, sure, but it's one of the best you can get in a mini PC right now, landing in the 91st percentile for graphics. Paired with 32GB of 6400 MHz DDR5 and a 2TB PCIe 4.0 NVMe SSD, this thing has no obvious bottleneck for gaming or creative work. One owner reports 150+ FPS in Le Mans Ultimate and Assetto Corsa Competizione with all settings maxed and CPU usage barely touching 20%. Another says it's the best option they've found for Flight Simulator 2024 in VR with a Quest 3.

The Core Ultra 9 275HX runs at 2.7GHz across 24 cores and includes a dedicated NPU for AI workloads. That's a 92nd percentile CPU for this category. The port selection is also a standout at 93rd percentile: Thunderbolt 4, two HDMI 2.1 FRL ports, DisplayPort, six USB-A ports, two USB-C, 2.5G Ethernet, and Wi-Fi 7. You won't need a dongle for much. The 330W PSU is doing real work here, and the triple-fan cooling seems to handle it without turning your desk into a wind tunnel.

Against the HP OMEN GT22-3080 and Lenovo Legion Tower 5a Gen 10, the ROG NUC trades raw upgradability for size. Those towers give you more room to swap parts and typically better cooling headroom, but they're towers. The Apple Mac Studio M3 Ultra is the closest philosophical rival, another compact powerhouse, but it's a different ecosystem entirely and won't run your Windows game library natively. The Dell Area-51 and CLX SET TGMSETRTU5204BM are traditional desktops that will beat the NUC on price-per-frame in most configs. What the ROG NUC offers is a unique combination: 91st percentile GPU performance in a chassis that fits anywhere, with port selection that beats most full-size desktops.

The price situation is messy. USD listings range from $4,660 to $5,148 across three vendors, a $488 spread for the same machine. That's not pocket change, and it means shopping around is not optional. The CAD listings are even wilder, spanning CAD 4,467 to CAD 7,574, a CAD 3,107 gap that suggests at least one vendor is hoping you won't check the competition. The cheapest USD option is the obvious starting point, but even at $4,660 you're paying a serious premium for the small form factor. You can get similar raw performance in a traditional tower for less money, but you can't get it in a 3.12kg box.

The ASUS ROG NUC RNUC15JNK9X28AAU packs a 24-core Intel Core Ultra 9 275HX and an RTX 5080 with 16GB of VRAM into a 3.12kg box. That's a desktop-class GPU in a chassis you can tuck behind a monitor, and our database puts the CPU, GPU, RAM, and storage all in the 91st to 92nd percentile for mini PCs. The compact score of 91.9/100 tells the story: this thing is built for people who want serious gaming horsepower without a tower taking over their desk.

But the reliability score sits at a mediocre 36th percentile, and social proof is dead average at 49th. Sixteen reviews averaging 4/5 stars is a thin sample, and one of those reviews is a 1-star complaint about missing Hyper-Threading compared to the previous ROG NUC 14. The hardware is impressive on paper. The long-term confidence is less so.

If you're buying this for business or productivity work, look elsewhere. The business score of 74/100 is the weakest area by a significant margin, and you'd be paying a premium for gaming hardware you won't fully use. Anyone who values long-term reliability should also think twice, the 36th percentile reliability score is not reassuring for a machine this expensive. And if you already own a ROG NUC 14 with an RTX 4070, one owner's experience suggests the lack of Hyper-Threading on the new Core Ultra 9 can actually hurt performance in some games. That's a rough upgrade path.

The ROG NUC RNUC15JNK9X28AAU is the fastest mini PC we've seen in our database, and it's not particularly close. The 91.9/100 compact score combined with top-tier CPU, GPU, RAM, and storage makes it a legitimate desktop replacement for gamers and creators who value desk space. But the 36th percentile reliability score and thin review pool mean you're taking a bit of a leap of faith. If you want the best small form factor gaming machine available right now and you can stomach the price, this is it. Just buy from the cheapest vendor and maybe get an extended warranty.
