Corsair ONE Pro SFF Gaming PC Review

Here are key points about the ONE Pro.


What's Hot


Superior Cooling and Noise: When I first saw the device at the event at CES, I wasn't so sure about Corsair's claims about noise and thermals since the room was loud and I didn't have my thermal camera on me. When I got the unit and powered it on, I was a little taken aback. I understood that the optimized thermal design of the unit allow the negative vacuum of the single fan design to pull air in through the radiators and then out the top. I understood Corsair was also taking advantage of the natural ability for heat to rise. I wasn't so sure how it would turn out in the end, or if it would be better than some other competitor products. I am now much more convinced about Corsair's claims; they really did an excellent job with cooling and thermals.



Latest in Gaming Hardware and you can Overclock!: Corsair tossed in a GTX 1080 and a 7700K, then water-cooled both of them. Together, the GTX 1080 and 7700K are the current go-to for high-end gaming components that won't empty your bank account. You can also overclock the 7700K, I was able to hit around 4.8GHz, but the thermal increases in such a tight space are very optimized for a stock 7700K. An overclock one does take you close to the 90C mark (stay under 1.3v). The 1TB SSD is a nice touch, but you can also get the Corsair ONE Pro with a smaller SSD and a larger HDD, which might be a better bet for most gamers with huge libraries.


Desktop Performance in SFF PC Size: What makes the Corsair ONE Pro possible is Corsair's custom design. With all their experience in chassis, AIO water-cooling, and SFF PSU design, I am not surprised they pulled off what many wouldn't have thought possible. Bringing MSI into the mix to help with the motherboard and GPU was a smart move since the two vendors can provide all the required hardware and can share expertise. MSI had a hand in helping customize a motherboard and GPU for high-heat, high-performance environments, while Corsair worked on cooling, power, and storage. The final result is a really nice, small form factor desktop replacement.


Excellent Connectivity: You get HDMI 2.0 at the rear and the front (Corsair had to use a custom breakout box to do this), USB 3.0 at the rear and front, and USB 3.1 type-A and type-C at the rear. While the system does have wired LAN, it also offers wireless-AC, and the WIFI card used performs admirably.


What's Not


Upgradability: The system is not easy to open and disassemble, and since the GPU unit is custom designed, you won't be able to swap in another GPU very easily. Storage space also seemed limited, but it does seem like you can swap out the SSD, but I am not sure how you would add another. I am a bit surprised Corsair didn't use an M.2 SSD. The one part you could swap out is the 7700K, but there isn't much point since there isn't anything better on the market for the socket.


Not for Low-Budget Gamers: The base Corsair ONE starts at $1799, which isn't that cheap. You could build a PC with the same parts for cheaper, but the Corsair ONE would probably beat it in size and noise.



Final Thoughts


There are some of you who might want to overclock your OEM PCs, and the Corsair ONE Pro is one of a few PCs that will offer this ability. The MSI UEFI is pretty much identical to a retail MSI motherboards' UEFI, with some tweaks here and there.


I was able to get the system to 5GHz for a quick run, but if you want something stable, you will probably land around 4.8GHz - which is still impressive for a system of this size.




Who would have thought a single exhaust fan was enough to cool down a 7700K, a GTX 1080, and the rest of the system? Corsair ONE Pro's size is actually its secret weapon. The size of the unit required the engineers to use very thin radiators mounted on both side, and the negative vacuum from the exhaust fan coupled with natural convection in a chimney style build produced a unique and effective cooling solution. The plus side is that you only have one exhaust fan and a large blower for the memory VRM, so noise can also be optimized.


Overall, I was very impressed with the system, and it's a very solid option for those who want a fully built gaming computer with little hassle and a lot of unique attributes.
