Customer Reviews

3XS Carbon is rated 4.6 out of 5 by 11.
Rated 5 out of 5 by from Excellent Product - Very Powerful Luckily enough I came into some money and decided to upgrade from the "nearly there" way into "ahead of there", "There", being a good computer to play games. This computer is above my expectations in build quality and performance, the neatness of the build was only marred by the unfortunate timeliness of my order, Scan were very busy when I ordered, so I had to wait a little bit longer than normal for it to arrive. It’s very difficult to write a review on something that was built to my specifications, to sit as a review for a specific product, what I can say is that is it well built, very tidy and works perfectly, it runs all the games I play in ultra-settings without breaking into a sweat. I am happy with the service and extremely happy with the performance.

Rated 5 out of 5 by from Just a Great 3XS System I must thank all the team at Scan Computers for the beautiful 3XS X99 Obsidian case system that has the feature of a 6-core Intel Core i7 5820K which is water-cooled and overclocked to 4.4GHz they built for me, I had to wait 2 weeks to set it all up after delivery as I was decorating a room to put the computer in. I was always kept appraised of the build and the expected delivery date which was kept to. There was only a few moans, these were that the delivery guy bounced the packages on our waste bins which had me cringing because of possible damage it could have done or did, When I finale got around to unpacking my 3XS X99 in a obsidian 750 case, the hard drive cage was out of position and had marked the glass area, the GPU was not in position and loose, and a stick of ram was also loose, I could not say if this was caused by the delivery or what seemed like a lot of packaging over all though I am very happy and pleased with my products which also includes a Swift PG278Q Monitor, I am having a great time and experience with my computer and have no problem reviewing and recommending a 5 star rating to all at Scan Computers.

Rated 4 out of 5 by from Powerful machine! Good performance, quiet fans and fancy case. Although it is a little bit large, I like it very much.

Rated 5 out of 5 by from Has restored my faith in PCs I've been a PC-based developer for the last twenty years, but four years ago I defected to the Mac which kind of spoilt me. However, now that Apple have grown too successful they seem to be letting their products (software especially) suffer so I was getting somewhat wound up with my latest iMac. A friend of mine had built their own PC and said it was really easy now (the last PC I built was in about 2008 and I always hated the feeling when you first turn it on to see if you've broken anything!). Somewhat spoilt by the Apple experience I wanted to buy a pre-built machine, but wasn't sure if I could 'afford' to. So I priced up all of the components at a number of sites (including Scan) for a self-build and then compared them to pre-built machines. To my surprise the difference amounted to about £170, which might seem a lot, until you notice that you save a bit on carriage, get a system warranty, save all the build time (and worry) AND they overclock the CPU for you... Suddenly it seems like a bargain. Whilst I was mulling over exactly what to buy I did look at the reduced price AMD Radeon 295X2 and even had Scan do me a custom quote (which was turned around rapidly and had an attractive price) - but in the end I couldn't justify the huge power draw and I've been put off AMD by their driver quality. In the end I opted for the i7 5820K, 2 x Nvidia 970, 16GB of Corsair Vengence, ASUS X99 motherboard, 512GB Samsung Pro SSD, 3TB WD Black HDD and a DVD drive. The machine arrived about a day later than I'd hoped (the waiting was soooooo painful!) and the box was enormous. I took out about two hundred feet of bubble wrap (slight exaggeration), including some from inside the case and powered it up... ...and it worked perfectly first time. The only sign of 'bloatware' were the burnin/performance testing software that Scan had left installed so that I could see how it ran - mmmmmmmm it ran amazingly. The machine is simply stunning. Blazingly fast and has devoured any of the games I've thrown at it (not sure how I managed on an iMac before this!): Elite: Dangerous, Battlefield 4 and GTA V are all >60fps at pretty high settings (Battlefield 4 multiplayer has never even been as low as 60fps, and GTA V is set to Ultra with some Advanced Options turned on) - this is all at 3440x1440 as well. The machine boots quickly thanks to the SSD and once paired with my nice AOC U3477PQU 21:9 monitor it is a dream. A massive thanks to Scan.

Rated 4 out of 5 by from arrived very well packed, woorking with no issues After slight delay due to supply issue of parts, the Computer arrived very well and safely packed and is now running blisteringly fast with no issues.

Rated 5 out of 5 by from Excellent service The machine arrived in good condition, as described, and it's leagues above my old computer. I'll be using this for years to come as my professional workstation, so I bought a lot of high end parts. It also runs GTA V like a dream, and I've had none of the issues other people online have complained about. Adobe AfterEffects also does RAM previews without slowing down at all. The extra USB ports at the front of the case are all working fine, which I'm pleased with since the PC I bought from another manufacturer seemed to neglect these ones. It's extremely quiet, and the saved overclock profiles are great.

Rated 5 out of 5 by from The PC I've always wanted... I've never dreamed of owning a Ferrari, but always wanted a specced out, top quality PC. This does not disappoint. I love my games and have only recently got back into PC gaming, and this machine is the rig I always wanted. The build quality is exceptional, the service was beyond efficient, and I'm already planning my upgrade path with this machine for years to come. I will be a Scan customer for as long as they provide this stratospheric level of quality in their machines and service alike. Top marks. Though it really grinds my gears watching my beloved wife read Buzzfeed on it when I could be playing Elite, or Grimrock or Red Faction... You get the picture. Please Santa bring me a Titan X GPU...

Questions & Answers

What is the recommended configuration for a silent build?

Asked by: MichaelL
With the level of performance on offer with the 3XS X99 Carbon you are unfortunately never going to achieve silence. That's by no means to say the Carbon is a noisy PC, its actually very quiet at idle and load thanks to the quality components/tech used throughout. If you wish to make it even quieter I would look at moving to a case like the Corsair 330R, Corsair 550D or Fractal R4. Then I would change the CPU cooler to the Noctua NH-U14S, Consider also dropping the OC from 4.4GHz to 4.2GHz as this will help keep the CPU temps from rising giving the cooler an easier job. If you wish to take it to the extreme, remove all mechanical HDDs and go for an SSD only based system.
