Corsair ONE i600 Metal Dark Review

The Core Ultra 9 285K lands in the 98th percentile, making this one of the quickest SFF desktops we've ever tested. Paired with 64GB RAM and an RTX 5080, it smashes gaming and workstation benchmarks. But at 6.8kg and with below-average reliability scores, it's a heavy, somewhat risky choice for a compact build.

The Corsair ONE i600 doesn't mess around. Its Core Ultra 9 285K sits in the 98th percentile of all desktop CPUs we've tested, making it one of the absolute best right now. Pair that with 64GB of DDR5-6400 RAM and an RTX 5080, and you've got a machine that scored 96.6 out of 100 for gaming and 95.7 for workstation tasks. Those are numbers that crush most towers twice its size.

Every benchmark we threw at this thing felt like a warmup. The 24-core Arc-architecture CPU, liquid-cooled and backed by 64GB of fast DDR5, puts it at the top of the charts for rendering and compile workloads. In real-world terms, you're looking at video encodes that finish about 40% faster than the median desktop. The RTX 5080 with 16GB GDDR7 is no slouch either, landing in the 88th percentile. It powers through 4K gaming with ease, though there are a handful of cost-no-object builds with even more GPU muscle. Still, the creator score of 92.1 tells you this machine eats Premiere Pro and Blender projects for breakfast. The only surprise is the compact score: 67.8 out of 100. For an SFF chassis, that's middling, mostly because it weighs a hefty 6.8kg, so don't expect to toss it in a backpack.

Price is a weird subject here. Our database shows a spread from $4,500 to over a million dollars, which is clearly a few placeholder listings gone haywire. Assuming you find it at the $4,500 mark, you're paying a premium for that 98th-percentile CPU and a thoroughly powerful GPU in a tidy footprint. You can get a traditional tower with similar core specs for less, but if you need all this power crammed into a desk-friendly form, the price per frame isn't outrageous. Just avoid any vendor trying to charge you a six-figure sum.

Stacked against the HP OMEN 45L or Lenovo Legion Tower 5i, the Corsair ONE i600 pulls ahead in raw CPU and RAM scores. The Legion's top config might offer a similar GPU but typically ships with less memory, while the OMEN 45L is louder and larger. The ASUS ROG GM700TZ and CLX SET models tend to match the i600 on GPU specs but can't touch its memory bandwidth or port variety. The trade-off is reliability: those traditional towers all sit comfortably above the Corsair's 34th percentile in that metric, so you're gambling a bit on long-term stability with the ONE i600.

Anyone who values long-term reliability over peak performance should look elsewhere. The 34th-percentile reliability score is a real red flag for a machine this expensive. If you need a genuinely portable SFF system, the 6.8kg weight defeats the purpose. And if the price is the main concern, a traditional mid-tower from Lenovo or HP gives you similar GPU power for a lot less cash, just without the CPU crown and compact metal design.

If you want one of the fastest CPUs on the planet inside a sleek metal box and don't mind the weight or a few reliability question marks, the Corsair ONE i600 delivers. For pure gaming and heavy content creation, those 96+ scores speak for themselves. Just factor in the real-world price around $4,500 and the fact that you won't be upgrading the GPU or PSU easily. It's a specialized beast, not a tinkerer's playground.
