A deliciously compact, good-looking, and powerful mini PC, with a unique internal layout and cooling system. I especially loved the touch-sensitive RGB slider on the front , and the blistering gaming performance from the liquid-cooled RTX 4080 Super. However, it’s very expensive and has limited U cooling, and it could do with more storage space.
Pros
Great build quality
Very compact
Excellent gaming performance
Cons
Very expensive
U gets quite toasty
Can be noisy under load
If you've dreamed of owning a high-end mini gaming PC, but didn't want the hassle of building one yourself, the Corsair One i500 effectively does this for you and then some. This custom case isn't just great looking, but it also features a unique internal layout and cooling system, with dual AIO liquid coolers strapped to the U and graphics card. It's exceptionally well made, and gorgeous-looking, plus its performance annihilates most full-size gaming PCs.

With a footprint that would fit inside a shoebox, the Corsair One i500 saves a huge amount of desk space compared to a full-size ATX system, but interestingly it doesn't use a mini-ITX motherboard like earlier Corsair One PCs. Instead, an MSI micro-ATX motherboard is used, which practically stretches edge-to-edge inside the case. This gives you a bit more flexibility for upgrades than a mini-ITX board too, with four DIMM slots rather than two, for example, as well as a couple of extra PCIe slots beyond the usual 16x graphics slot.
There are two specifications from which to choose, with our review sample sporting an Intel RTX 4080 Super, a 2TB Samsung PCIe 4.0 SSD, and 32GB of Corsair 6000MHz DDR5 memory, which costs $3,599.99.
If you pay an extra $1,100 you'll get a GeForce RTX 4090 and 64GB of memory. It's a shame, though, that there's no option to upgrade the SSD, given that the micro-ATX motherboard has plenty of free M.2 slots, and this is meant to be a high-end gaming PC. For nearly five grand, you'd expect a 4TB SSD as standard.
It's still a monstrous specification, though, with the Core i9 14900K offering a total of 24 cores (eight P-Cores for all-out performance, and 16 more power-efficient E-Cores). and a peak clock speed of 6GHz. However, the first issue we saw is that the U rarely, if ever, hits this speed, and its multi-threaded load boost clock speed across all P-cores was only around 5.4GHz. That's a couple of hundred megahertz lower than we've seen this U model hit under multi-threaded workloads in other rigs.
A big factor is, of course, the high temperature output of this U, as well as the amount of power it consumes, but the situation isn't helped by the fact the Corsair One i500 only has a 120mm AIO cooler dealing with this monstrous processor, with only a single slim 120mm fan shifting hit away from its radiator. That's simply not enough cooling horsepower to deal with Intel's current flagship U.
Thankfully the GPU has double the cooling capacity, with a 240mm radiator, and its peak GPU temperature in games of 64°C was excellent, easily being on par with the best air-cooled cards out there. The graphics card memory became quite toasty at 76°C, but this wasn't hot enough to reduce its frequency.
Meanwhile, upgrading the PC is relatively easy, as two side fans, including the 120mm AIO liquid cooler, swing out on a bracket, giving you easy access to the memory, SSD, U, and the MSI B760M Mortar WiFi micro-ATX motherboard. That's just as well, because Intel's next-generation Arrow Lake Us won't be compatible with this motherboard.
Features
Despite the Corsair One i500 being very compact, it boasts the full complement of ports on both the front and rear s, with both these areas having a USB-C port, and the rear one offering 20Gbps USB 3.2 Gen 2×2 speed too.
There are two USB 3.0 ports on the front and a total of seven Type-A USB ports on the rear I/O , so no one will be left wanting here. There's no Wi-Fi 7 , but this is pretty rare on any motherboard at the moment, and the Corsair One i500's Wi-Fi 6E and 2.5Gbps Ethernet port are fine for networking options.
Meanwhile, the central spine on the front is a slide control for the RGB lighting in the front and base, for example, allowing you to control the brightness and color, while the freely available Corsair One dashboard software gives you finer control, including lighting effects. Sadly, the software didn't allow us to alter the fan speeds, while the Corsair One i500's motherboard EFI (BIOS) only seemed to control one of them, so most of the fans are automated and can't be tweaked.
I was really pleased to see Corsair going beyond the usual one-year basic warranty for this PC system, though. Should anything go wrong with the PC, then you have a two-year parts and labor warranty, with Corsair either fixing or replacing the whole unit, and you get a lifetime of technical too.
Design
The Corsair One i500 case is elegant, well-made, and sturdy – the build quality on display here is just superb. The dark wood ing on our review sample also looks fantastic, and a lighter wood is available if you prefer as well. Cable tidying can be troublesome in small PCs, but Corsair has done an excellent job inside the small confines of this system, especially on the rear where the wires are all neatly tucked away and secured with Velcro ties.
Two magnetic dust filters are attached to side s to keep any muck out of the interior. The underlying vent pattern in the side is also quite attractive, but the dust filters hide a lot of lower RGB lighting, which is only able to shine down onto your desk. We don't doubt having large vents is useful for airflow, but they don't feel quite in keeping with the luscious materials used elsewhere in the system.
The airflow system also means that dust ends up getting trapped on the exterior of the case too, requiring regular cleaning to keep up appearances, especially over the two 120mm side intake fans. You'll need to avoid placing anything on the roof too, as this is the main hot air exhaust area.
The RGB lighting could also be a little more visible on the front . Two RGB lighting strips sit on either side of the wooden fascia, but the side s hide it at most angles unless you're facing the PC head-on. Given how much the lighting can be customized, we'd honestly like to see more of it given the unique RGB controller Corsair has gone to the trouble of making.
If there's one complaint about the design, it's that the Corsair One i500's fan noise is fairly loud in games, with the two roof fans that cool the GPU's liquid-cooling radiator producing most of the noise; more than you'd expect from an average air-cooled RTX 4080 Super card.
Again, the lack of any fan control here does mean you're stuck with this noise, which is a shame as we'd prefer to cut fan speeds slightly, given that the GPU ran far cooler than average in our tests. The noise isn't deafening, but we'd definitely describe it as intrusive, especially if you have the PC on your desk a couple of feet away from you.
Benchmarks
While half the point of the Corsair One i500 is to turn heads and create a compact custom tower of power, the other half is very much about performance in games and content creation, where benchmarks reveal all. Cyberpunk 2077 is a great workout for the latest games hardware, and the Corsair One i500 averaged 75fps in this game at 2,560 x 1,440 with the Ultra ray tracing preset enabled.
That's already a decent result, but it went all the way up to 106fps with some help from Nvidia DLSS 3 and frame generation enabled. This clever tech uses AI to create extra frames in between the ones rendered by your graphics card, in order to smooth out the frame rate, and it works remarkably well.
We couldn't quite get this spec of the Corsair One i500 to return a smoothly playable frame rate at 4K with the same settings and DLSS frame generation, but its average of 51fps here is still pretty good – you'll only need to drop the settings a little, or enable DLSS Super Resolution, to get this game running smoothly at 4K.
Meanwhile, Formula 1 2023 was a little easier for this spec of the Corsair One i500, with an average frame rate of 63fps at 4K and 111fps at 2,560 x 1,440, rising to 94fps and 145fps respectively once DLSS was enabled. This is edging into high refresh rate monitor territory, which is amazing for these high graphics settings.
Finally, Total War: Warhammer 3 also saw some monstrous frame rates, with a minimum of 121fps at 2,560 x 1,440 of 121fps and an average of 151fps. Its 4K performance was unsurprisingly lower, but it still managed a respectable average of 80fps in this game. Basically, this mini PC really can play games at very high graphics settings with decent frame rates.
Meanwhile, our synthetic benchmarks revealed performance that's typical of a GeForce RTX 4080 Super, sitting just below an RTX 4090 in the 3DMark Time Spy Extreme test, with an overall score of 14,136 and a graphics score of 14,349. The standard Time Spy test revealed a similar result, with the graphics score of 28,676 right at the top of what we'd expect from this graphics card.
The U is really fast too, even if it struggles to hit its peak clock speeds. Switching to the 3DMark U profile test resulted in the maximum threads score of 16,114 pipping the Ryzen 9 7950X to the finish line, and more than doubling the score you'd typically see from a Ryzen 7800X3D too. Meanwhile, Cinebench R23 is a freely available benchmark and here the single-threaded score of 2,289 is faster than any result AMD can currently muster, while the multi-threaded score of 37,392 was a match for what you'll typically see a Ryzen 9 7950X scoring too.
Remarkably, this high-powered spec doesn't draw an enormous amount of power from the mains either. We noted a peak of 531W being drawn from the wall during gaming sessions, which is pretty efficient for the amount of gaming power on offer, especially with this notoriously power-hungry U.
Price
There's no denying the Corsair One i500 is extremely expensive, but you do get a high spec in both options. The price of the Core i9 14900K U and RTX 4080 Super GPU alone are already $620 and $999 respectively, before you've even ed for the rest of the gear, and then you need to factor in the ingenious design work that's gone into the gorgeous custom chassis and cooling system.
Yes, a similarly specified, full-size desktop PC will be cheaper in a lot of cases, but it won't be as small and stylish, and that's all a part of the One i500's package. It's expensive, but the price is (just about) fair for what you get.
Verdict
The Corsair One i500 is one elegant, achingly sexy PC, earning a spot on our best mini gaming PC guide. The wooden s look fantastic, the desktop footprint is small, and Corsair has put a serious amount of work into the design of its custom chassis. Hats off to the engineering team for managing to squeeze a liquid-cooled Core i9 14900K and RTX 4080 Super into this compact space.
This mini PC does have some shortcomings, though, namely the limited cooling for its hot-running Core i9-14900K processor, and a GPU liquid cooling system that, while effective, dishes out more decibels than most air-cooled RTX 4080 Super cards I've tested.
Corsair will no doubt argue that this liquid cooling system was necessary to be able to house such a graphics card in such a small space, but the ability to tune the fan speeds would really help here. Thankfully, the hot-running processor still performs as expected in all our tests, and it's never going to be running at peak load across all cores when you're gaming either. The noisy GPU cooling system is more of an issue, though, as it sounds intrusive in games, and we can only imagine the RTX 4090 model will compound that issue given it has the same cooler.
You won't notice that noise so much if the machine is under your desk, but the Corsair One i500 isn't a system you want to hide away – you're going to want its good looks on display on your desk. If you have the money, and you want the best-looking, most powerful mini PC you can buy, then the Corsair One i500 is it, but we recommend gaming with a headset to drown out the fan noise.
Alternatives
Origin Chronos
Origin, which is owned by Corsair, also makes a range of tower-shaped mini PCs with a small desktop footprint, and with similarly high specifications. The Origin Chronos V3 can similarly be kitted out with a Core i9 14900K and a GeForce RTX 4080 Super, but there's also the option to spec up a cheaper version based on a Core i5 14600K with an RTX 4060 Ti. The Chronos V3 doesn't have the smart good looks of the Corsair One i500's wooden chassis, but it's similarly compact and much cheaper.
