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.

Date published: 2020-02-04
Rated 5 out of 5 by from This bundle is a powerhouse I've been meaning to upgrade my system without having to buy all the components again such as tower case, SSDs, PSU, GPU, etc... and as such this bundle was perfect for me. Coming from a 2013 Phenom II X4 945 build all I can say is: "Wow!". I use my PC for games and even without changing my trusty 2GB GTX 770 I've seen a drastic improvement in loading times and a much more stable FPS. Windows loads within seconds (I did have to purchase a new copy of windows, but you can get OEM versions very cheap nowadays) The pulsating LEDs make me feel like I'm now living in the future! The cooling unit is silent compared to the absolute jet engine cooler my previous build utilised! I have the option to upgrade even further and feel that this bundle will future-proof my build for a very long time. The only issue I came across was on my side. I have a Corsair Carbide 300R tower and had to make some customisations in order for the cooling unit to fit. So I would definitely make sure that you check your towers specs before purchasing! The only worry I had was that my research showed that the i9 can get very hot even in idle mode. I have attached an image to show a cool temperature when idle. When playing games I have yet to see the temperature go above 60°C. On first load I did also encounter the issue as mentioned in a previous review in regards to the machine turning off and on again. But it only ever happened to me once and it's been plain sailing since. All in all I am over the moon with my purchase and can't suggest this bundle enough. Also you get a free Scan hat! ;)

Rated 5 out of 5 by from Breathtaking Performance, even for its price Before I start, I'll mention that I'm using a different account to the one I used to purchase this since I prefer to use a different alias. This bundle is breathtaking, it really is. Packaging wise, it comes with the motherboard box and all its freebies and the 3XS box with the bundle in. The bundle was wrapped in bubble wrap which I presume is non conductive, and firmly held in place within the box, covered entirely. In the motherboard box I received the usual freebies, a cablemod discount, the CPU lid, box and packaging and some stickers along with the motherboard drivers. More on the drivers later. It's worth noting that I did not receive the full i9 9900k hexagonal shaped packaging which I would have liked as a decoration, but that doesn't bother me too much. Installation was easy, the only complication being that the motherboard is a very, very tight fit in my case (full size ATX, XPredator X3) especially around the IO slot. The RAM, CPU and cooler come already installed and it was as simple as plugging in my graphics card and cables and I was ready to go. On first startup windows did require a new licence, so if you're using a fixed licence that is non transferrable it is worth noting that you'll need a new one. Other than that it booted into the desktop after configuring the new hardware. Now is the time to make sure everything is there before installing the drivers. When installing the drivers for the motherboard I did encounter an issue with Sonic Studio III. When copying and pasting anything (images or text) I was getting a crash DMP link quite often. You'll want to remove sonic studio, since this causes that problem. I haven't reinstalled it since, I just used the realtek audio console instead and all works fine. Now for the actual performance of the bundle! I'm using an Asus 1080 Strix and two SATA SSDs with this bundle, so performance may vary slightly for those with older or newer hardware in the GPU and storage department. However for the most part it should be quite similar: With autostartup programs disabled (Discord, iCUE, etc) but background windows processes untouched, I got a cinebench score of 2150. As I do a lot of video editing, I did a more extensive test here since it is a real world test and not a synthetic one. For this next test in Premiere Pro it is worth noting I used the Voukoder plugin which utilises NVENC assisted H.264 encoding resulting in faster render times for the same compression quality as regular H.264. Encoding a 20 minute, 4k60fps DOOM gameplay video at a variable bitrate of 50,000 to 70,000KBps, the CPU was almost constantly at 100% (which is the best case scenario) but temperatures never exceeded 55 degrees C, even when both the CPU and GPU were under full load, utilising a full 26GB of RAM. The encode took 17 minutes, indicating that with the correct setup rendering H.264 assisted by NVENC in 4k can be rendered in faster than realtime using this bundle. This is insane! My ONLY issue I've had with this is that every time I start up my PC using the power button, it will turn on, off, on, off, and on before starting up properly. This usually only happens after a power cycle of the PSU. My PSU is an EVGA 850W, more than enough for this bundle. It might well be it's getting old but this didn't happen with my previous system, using a 4790k CPU. This problem is probably unique to me, so I shouldn't worry about it. The other minor problem being I didn't get the fancy i9 packaging, but compared to how amazing this bundle performs I don't really mind. Some great work from the 3XS team that put this bundle together. Performance is amazing, temperatures are amazing and never go beyond 60C maximum, and I'm incredibly happy with this bundle. If you have the money and are considering buying it, I cannot recommend it enough!

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,

Can you get this with 32gb ram

Also is it possible to get it without the cooler plan is to put it in a custom water cooled system?

If I ordered this today, does the motherboard come with the latest Firmware and is then manually overclocked based on this?

Asked by: OliverTerry
Hi, Not necessarily the very latest BIOS but it will be very recent. We typically have these on the shelves for a couple of weeks after assembly so it could be anything up to that kind of age. Kind regards,
