First announced in February, the new Corsair ONE pre-built gaming PC is now shipping. The Corsair ONE is the first ready-to-run system from the manufacturer that has mostly been known for their PC components and peripherals. Selling and supporting entire systems is a new venture for Corsair, but the design and capabilities of the Corsair ONE are a good fit for the company's product lineup.

The Corsair ONE uses a custom case form factor that is a shallow-depth mini tower, but all of the major components inside use standard PC form factors: mini-ITX motherboard, SFX power supply, 2.5" SSDs and supporting graphics cards up to 11" long with two or three slot cooling solutions. Naturally, many of those components are either existing Corsair parts or special editions made for the Corsair ONE. The total volume of the case is around 12L and the exterior is mostly black aluminum.

The system's cooling is provided by a single ML140 exhaust fan at the top and intake is through the side panels. The right side intake is occupied by the radiator for the CPU's closed-loop water cooler. The left side intake vent opens directly onto the air-cooled graphics card in the base model, while the top Corsair ONE includes a second water cooler for the GPU. Neither radiator has any fans of their own, as the exhaust fan at the top of the case provides most of the air flow. The power supply uses semi-passive cooling with its own fan, and the system as a whole emits around 20dB at idle.


In order to allow the graphics card to be positioned behind the motherboard and facing its own air intake, the Corsair ONE chassis provides the necessary cables to route the PCIe lanes to the graphics card, and pass-through video connections to ports on the back and one HDMI port on the front that is intended for VR displays. The power supply is mounted in the top of the right side of the case and also makes use of a short pass-through cable to the plug on the back of the machine. Because both side panels are used as air intakes, the Corsair ONE can only operate in vertical orientation cannot be operated with either side directly against any obstructing surface.

The top vent and fan are removable without tools, but the two side panels with the radiators must be unscrewed at the top and are hinged at the bottom. While Corsair cases are usually quite easy to work in, further disassembly of the Corsair ONE gets tricky as usability has been sacrificed to save space.

The base model Corsair ONE comes standard with an Intel Core i7 7700 processor in a Z270 motherboard with 16GB of DDR4-2400 RAM. The base graphics card is an air-cooled NVIDIA GeForce GTX 1070. The Corsair ONE PRO model upgrades to a Core i7 7700K processor and a MSI GEFORCE GTX 1080 AERO 8G OC with Corsair's custom water cooler. Storage is either a combination of a SATA SSD and a 2.5" hard drive or a single larger SATA SSD.

Stylistically, the Corsair ONE is less ostentatious than many gamer-oriented products. The front face of the case includes aqua blue accent lighting that can be controlled or entirely disabled through Corsair Link software, but it's single-color rather than full RGB lighting. Even with the lighting off the Corsair ONE doesn't easily blend in with typical office or living room furnishings, but the relatively small size and all-black color scheme make it fairly unobtrusive.

The software pre-installed on the Corsair ONE is minimal: Windows 10 Home with all the necessary drivers, Corsair's CUE customization tool, and installers for popular game digital distribution platforms including Steam, Origin, Uplay and GoG Galaxy.

Corsair will be selling the Corsair ONE PC through major electronics retailers as well as directly through their online store. Support will be be handled in-house by Corsair's expanded support department that now includes specialists for the Corsair ONE. The system comes with a two-year warranty and aftermarket upgrades performed by the consumer will void that warranty, but Corsair will also be partnering with retailers to provide in-warranty aftermarket upgrades.

    Errr... The mark up IS high: Corsair are using their own branded products, seriously?! Even then compare this with Scan 3XS Vengeance Ti:
    Intel Core i7 7700K overclocked to 4.8GHz (by Scan folks)
    Asus ROG Strix Z270F Gaming
    16GB Corsair Vengeance DDR4 3000MHz
    11GB NVIDIA GeForce GTX 1080 Ti
    256GB Intel 600p M.2 SSD & 2TB HDD
    Microsoft Windows 10 64bit & 3 Year Warranty
    £2028 including delivery
    Versus Corsair One Pro @ £2199 (currently frer shipping).
    Funnily enough most of the 3XS components are Corsair including the AIO cooler, hehe.

    That Vengeance is noisy as hell. No thanks,
  • K_Space - Friday, March 24, 2017 - link

    3XS Ti = 44.8db Corsair One ?Pro = 40.7db (both reviewed at Scan) bearing in mind you could slab a Carbide 'Q' variant case instead, e.g. 400Q and watch the noise level plummet (by 60% no less according to anandtech own review). Given that the equivalent Corsair One Pro 1080Ti version is available for the sum of £2,599 GBP, I'd certainly call that pricey as hell.
    The kicker is that the precious 2 year warranty from Corsair is invalidated the moment you start meddling with the insides... Including installing your favourite M.2 SSD. So your choices: ? mahssoive mark up on every component upgrade on custom rig or ?as professionally built 'standard' rig for £££ less.

    Looking on Corsair website they list a version with a 1080ti for $2599 USD, but it still has a SATA drvie and 2400 DDR4. Tempting to buy it, install a NVMe drive, replace the 2400 DDR4 with faster DDR4, and sell the 2400 used. Would be a beast.

    Too bad you have to take the whole thing apart to install an M.2 drive. It's on the back of the motherboard.

    Kudos on the design! I definitely like it.

    However, the pricing is way too high. I understand it's customized & maybe you can call it a "boutique" kind of gaming PC, but I'd rather just build my own Silverstone mini-ITX gaming PC for a lot less money.
  • Drumsticks - Thursday, March 23, 2017 - link

    Earlier comments have already mentioned the markup really isn't that bad, especially considering you're getting two 240mm liquid coolers in the top end model. That's a bit more advanced than what's available to cool most SFF cases.
  • romrunning - Thursday, March 23, 2017 - link

    Well, the markup may not seem too bad, but it seems to be adding at least $400-700 more to the price - if we go by what others have said about similar build-outs vs the "Pro" version.

    I do hope this stirs more competition from other case makers to create some newer mini-ITX designs. Who knows, maybe Corsair will even release this one as a standalone case.
  • Hxx - Thursday, March 23, 2017 - link

    the price will most likely drop very soon. The pro version is about 1k more than it should be.
  • fanofanand - Thursday, March 23, 2017 - link

    At the risk of adding to the echo chamber, I was very attracted to this until I got to the price. Coincidentally I have been doing a few of my own mock-builds to get an idea of how far my money would stretch today. Turns out for about $1900 I could build a system with a 1080 and an 1800x, with a 500Gb M.2 SSD and an 80 plus gold PSU. RAM was 3200 with CL15 (16 Gb) and a decent Asus Prime Pro X370 and a decent case with liquid cooling. That particular build would appear to beat this by 75-100% depending on the activity, for the same dollars. Granted that case was about 21 Liters vs the 12 here, but unless you literally cannot fit a larger case this is just a halo product meant to display what Corsair can do. I wouldn't expect many to actually buy this.
