“The Corsair One i300 is a gaming PC with a striking design and plenty of powerful components. Expect to pay a premium for the experience, though.”
Tom2022
“The same is true in our default Final Fantasy gaming tests across all three common resolutions. Newer drivers no doubt help, yet there’s no denying this is a well-tuned, finely integrated gaming powerhouse.”
Club3862022
“The Corsair One i300 is a gorgeously-designed compact small form factor gaming PC with some of the very best components money can buy. It is also incredibly expensive, and some of the specs will be overkill for most gamers.”
TechRadar2022
“The Corsair One i300 is a compact gaming PC with high-end parts. It won't take up much room on your desk, though you’ll sacrifice some upgradeability for the size. You'll pay a lot of money for it, but you'll get big performance in a small package.”
Tom2022
“I'd like to take a moment to encourage Corsair to offer a wider variety of components in the future. Admittedly, this may be already in the works as older Corsair One systems are available with Core i7 CPUs, but any way to make this prebuilt PC more accessible by offering...”
PCGamesN2022
“The Intel Wi-Fi 6E AX211 module built into the main board is the most current available, so you can also use Wi-Fi 6G networks. Using our current test router, which also supports the newest standard, the Corsair One i300 delivers fast and stable transfer rates in our WLAN test.”
Notebookcheck· Sebastian Bade2022
“After that, it's a matter of removing two screws and gently lifting the left panel free. The MSI MEG Z690I Unify Mini-ITX motherboard is accessible within; you'll need to work around the tubes coming off the CPU waterblock.”
PCMag Canada2022
“Below the motherboard area, we can note the PSU, a Corsair SF750 80+ Platinum unit. This is a very high quality power supply and gave us no problems at all during our testing, and it's good to see Corsair put in effort to keep the cables as tucked away as possible, leaving...”

Loved

+ Strong CPU and GPU performance
— Tom
+ Compact, 12-liter chassis with small footprint
— Tom
For that price you're getting some of the best tech out there, such as a liquid-cooled Nvidia RTX 3080 Ti GPU and an Intel Core i9-12900K 16-core processor. There’s also 64GB of DDR5 RAM and a 2TB M.2 SSD.
— TechRadar
Performance wise, however, this is a beast, and will handle any modern game at 4K with relative ease. The RTX 3080 Ti is one of the best GPUs in the world, and coupled with a new 16-core 12th generation Alder Lake processor from Intel, games such as Cyberpunk 2077 and Metro...
— TechRadar
What’s particularly impressive about the size of the Corsair One i300 is its sheer power. We’ll get onto that in a moment, but essentially this is one of the most powerful gaming PCs you can buy right now, and also one of the smallest. That’s a pretty potent combination.
— TechRadar
The chassis is small, but solid. The RGB lighting is more subtle than many gaming PCs, and the brushed metal design of the Corsair One i300 means that non-gamers should be perfectly happy to have one of these sitting on their desk in an office or studio.
— TechRadar
It might have been reasonable to expect a small-form-factor PC to fall short of much larger systems in certain tests. That hasn’t happened yet; Corsair’s One i300 doesn’t just hold its own, this little beastie typically tops the charts.
— Club386
M.2 SSDs are the perfect illustration of how enthusiast components needn’t be big. The 2TB Samsung drive offers good capacity and ultra-fast performance in a tiny form factor befitting a system of this size.
— Club386
Make no mistake, this is a serious amount of firepower, as you would expect at the £4,400 price point. Few PCs offer this level of oomph in a package that lives effortlessly atop a desk, and Corsair’s tidy implementation extends to software.
— Club386
A few visual tweaks wouldn’t go amiss, yet there’s no questioning the fact that Corsair One succeeds in delivering an optimal balance of cooling and performance.
— Club386
The One i300 scored exceptionally well, vying with the other Core i9-12900K machines for top honors. It handily outpaced the Ryzen-powered Maingear in most instances.
— PCMag Canada
The Corsair aced our first test, UL's PCMark 10, which simulates a variety of real-world productivity and office workflows to measure overall system performance. Its 2TB PCIe 4.0 SSD helped it achieve the highest score in the primary drive storage test.
— PCMag Canada
The Corsair One's simple yet highly effective liquid cooling differentiates it from other compact desktops. A 140mm top fan draws air through the perforated side panels, behind which are the liquid cooling radiators for the processor (on the left) and the graphics card (right).

Criticised

More difficult to upgrade than standard towers
— Tom
The Corsair One i300 comes with some seriously impressive specs, packed into a unique and stylish slim chassis. As previous Corsair One PCs have shown us, you shouldn’t expect the i300 to be cheap – but at $4,999, this is an incredibly expensive PC.
— TechRadar
More RAM than needed for games
— TechRadar
It's also plainly overkill if you’re using this for just gaming. That 64GB of DDR5 RAM isn’t going to make much of an impact. For digital creatives and content makers, however, there may be better justification.
— TechRadar
Even with the kind of spec on offer here, this is a very pricey desktop PC, and it means Corsair needs to do a lot to justify the asking price. Putting it into a small and stylish chassis is definitely one of the ways the company is going about that.
— TechRadar
Micron supplies the two 32GB sticks of DDR5-4800 memory, and bandwidth is plentiful. Latency, on the other hand, continues to be DDR5’s Achilles’ heel.
— Club386
Step-by-step instructions on how to upgrade certain components are provided, albeit with the proviso that Corsair’s standard two-year warranty will be void should you fail to follow the instructions or use invalidated parts.
— Club386
Let’s start by getting the £4,400 elephant out of the room. Corsair One has always attracted a premium, and the latest iteration is no exception.
— Club386
Upgrading the CPU or GPU would require more extensive disassembly, and in the case of the latter it'd be a challenge to find a GPU that would work. You're best off buying this tower with the processor and graphics card you want from the get-go.
— PCMag Canada
You can see how the cooling system works with some minor disassembly for upgrades. The One i300's expansion is limited to two RAM slots (using desktop DIMMs, not laptop-style SO-DIMMs), one M.2 2280 slot for an SSD, and one 2.5-inch drive bay.
