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.

Questions & Answers

What watt powersuply would i need for this

I'd be using a 1080 with the bundle i currently have a 750w power supply is that sufficient
Asked by: shywar
Hello, Most 1080's only recommend a minimum of ~500w for the PSU. If you are combining this bundle with a 1080 then 750w should be sufficient. Regards.

Does this bundle come with Windows

I was checking the custom build options on 3xs and the operating system was an option but I don't see that listed here.
Asked by: Zorodek
Hi, This bundle does not come with a copy of Windows, you would need to purchase one separately. I hope this helps. Kind regards,

4.9GHz on all cores or just 1?

Hello, I am thinking of purchasing this bundle for Christmas. The specification "Overclocked to 4.9Ghz" - Is that on just one core, or across all 8 cores when active. I'm wondering since the per-core speed of this CPU is 5GHz. Thank you.
Asked by: Linx
Hi, We overclock the 9900K so that it runs at 4.9GHz under any core load, so whether a single core is being utilised or all 8, it will turbo to 4.9GHz. At the default Intel specification the 9900K will only hit 5.0GHz with a one or two core load, which in OS environments is quite rare and indistinguishable between 4.9GHz. Overall our 4.9GHz overclock out performs the standard spec as typically a 9900K will only turbo to 4.7GHz. I hope this helps. Kind regards,

Will this cooler be sufficient?

Will the H100x cooler be sufficient to run this processor under full load (EG: Video editing, rendering) without thermal throttling / crashes? I've read conflicting information regarding how to cool this processor and I'm looking for a more creditable response which I hope I can find here. Thank you.
Asked by: Linx
Hi, All of our 3XS systems and bundles are tested to ensure that they do not throttle when overclocked, even under AVX instruction sets. As long as you have a solid PSU and a chassis with good airflow then our product will work perfectly for you. I hope this helps and if you have any further questions then please do not hesitate to email me directly at [email protected] Kind regards,

Do you add too or change bundles?

Hi, If I wanted to add 2 more memory modules to make it 32GB and change the cooler for a Corsair H150i Pro would you do this as a 3XS bundle? Thanks, Pete.
