3XS Bundle vs Self-Built

Anyone can build a PC, so what really makes the benefit of a 3XS bundle? For starters, our team has been designing and building PCs for more than 20 years, so we have a huge amount of experience in building highly reliable systems that deliver the most performance for your budget. These are the benefits you receive when buying a professionally built 3XS system versus building a system yourself.

Assembled & Overclocked

An overclocked bundle is professionally built in Scans state of the art 3XS Lab, each bundle undergoes a 24 burn test to guarantee stability. Your bundle will be shipped out fully built in a custom box which includes all the original component packaging.

No Compatibility Headaches

It can take weeks to research the right combination of components, not just to ensure you get the most bang for your buck but to minimise the chance of one component being incompatible with another. Whether you buy a system from our configurator or a custom spec system our engineers will do all this hard work for you, ensuring that when your system is delivered it performs flawlessly.

Intensively Tested

Building a bundle only takes a few minutes, but making sure that everything is configured properly and that the overclock is stable takes up a huge amount of time. By ordering a 3XS system our engineers take this painful process away, as all our systems undergo a strenuous Quality Control procedure which includes installing the latest motherboard BIOS and the aforementioned 24 hour burn test.

Peace of Mind

Unfortunately PC components do occasionally fail, and when this happens if you’ve overclocked the CPU yourself you’re on your own. However, with a professionally built Scan 3XS overclocked bundle you’re no longer alone. Your bundle is covered by a 2 year return to base warranty and our technical support team is available 7 days a week, from 9am to 10pm Mon - Fri, 10am to 6pm on Saturdays and 10am to 4pm on Sundays. Click here for more info on how to get technical support for your 3XS system.

Widely Acclaimed

Our 3XS PCs have won hundreds of awards in the press from publications such as Custom PC, Develop3D, Expert Reviews, HEXUS, PC Gamer and PC Pro. In addition 3XS has won Custom PC’s annual Dream PC competition every year it has run since 2007. You can read all our reviews here plus customer reviews on the configurator.

3XS Z390 Overclocked Bundle, Intel Core i9 9900K Coffee Lake, ASUS ROG MAXIMUS XI HERO, 32GB DDR4, Corsair Hydro H100x is rated 5.0 out of 5 by 6.
Rated 5 out of 5 by from Flying machine & worry free upgrading A great price for a high quality product backed by the usual excellent Scan warranty...and it is whisper quiet too. Firstly I wanted to mention actually installing these boards if you are new to the process as I am. The time had come to upgrade the i7 4770K processor, motherboard, cooler and RAM in the Vengeance Titan (6Gb) system Scan supplied me some 5 years ago. I've only replaced the graphics card and RAM before so had no real concept of what replacing a pre-build motherboard (processor, RAM, and cooler installed) would require. Watching a few YouTube videos on the subject gave me enough confidence to give it a go. I'm glad I did too because as long as you have the time and patience to work out where all the connectors are on your old board and the new one it is a straight forward process. The motherboard manual is easy to read and helps a lot too. The individual process will vary slightly but I'd encourage anyone with even basic knowledge like mine to give it a go. You will need a good magnetic screwdriver for some of the smaller screws! Also make sure you've got a Windows installation USB drive ready to install windows once you are done with the install! A quick trip to the bios, set boot from USB and before you know it, Windows is back up and running. Ok enough of my installation anxieties! This i9 9900K bundle is a true flying machine. Running the latest simulators via a GTX 1080Ti card and in Oculus VR the experience is stunning. This is exactly the experience I was looking for from this upgrade. An added bonus is that the system is almost silent compared to the previous Corsair H100i cooler. Aside from the occasional fan noise flare during intense action it is whisper quiet. I'm now a long term more than 5 year customer of Scan and they've delivered on both price and quality every time. Highly recommended.

Rated 5 out of 5 by from Does what it says on the tin Bought this package just prior to Christmas to replace an ageing I7-930 system Comes with everything pre installed so if your putting this into a smaller case can make it slightly harder with positioning due to having the rad attached. Bios had 2 profiles installed one for stock and one for Overclocked seems to be running great so far although im still loading everything on it and havent really used it in anger so to speak yet. Only real negative for me was witht he rad being pre installed i had to switch the fans around from push to pull for hoiw i wanted to install apart from that no issues at all.

Will it fit my case ?

I have a Corsair 600T Graphite Series Mid Tower Case (no longer made - LN34557). It was bought in 2012. I last upgraded in 2016 and the bundle I bought then fitted. Will this bundle fit my Corsair case ? Trevor
Asked by: TeeCee
From the original question setter. Since there have been no replies, I suspect that I haven't given enough information. The last bundle I bought (which fits in my case) included an "Asus ROG Max VIII Ranger Z170" mother board and a "Corsair Hydro H100i CPU Cooler". I hope this can prompt an answer to "Will it fit?". If it won't fit than can you make a recommendation for a case to replace my current one ? It would not need a power supply. Trevor

Will this fit in Cosmos 2 ultra tower 25th anniversary edition?

Hi, does this bundle come fully assembled and will it fit in the above case. If possible, could you direct me where the cooler would fit on the case thx
Asked by: Pete72
Hi, I can confirm that this bundle would be compatible with the Cosmos II chassis. I would advise that you fit the 240mm radiator on the roof of this chassis as an exhaust. I hope this helps. Kind regards,

What cooling is required?

I've just read a review of the 9900K which suggests that air cooling is not adequate and it really needs a liquid solution. Is there any truth in that?
Asked by: Beztom
Good Morning, Liquid cooling is not required but you would need a high-end air cooler for this CPU. For a Liquid cooler, I would recommend going for the CORSAIR Hydro H100i - https://www.scan.co.uk/products/corsair-hydro-series-h100i-rgb-platinum-240mm-all-in-one-hydro-cpu-cooler-2x-120mm-ml-pro-rgb-fans-r And for an air cooler, I would recommend going for the be quiet Dark Rock PRO 4 - https://www.scan.co.uk/products/be-quiet!-dark-rock-pro-4-dual-tower-cpu-cooler-7-heatpipes-120mmplus135mm-silent-wings-pwm-fans-al I think the above would be great choices in terms of cooling for the i9 9900K. Kind Regards,
