PC Specialist Cosmos II 15.6″ Notebook Review

by - 7 years ago




When it comes to finding a decent-spec notebook you will be overwhelmed with options. If you’re after something slim and stylish you’re likely to be stung for a hefty premium by Apple, Sony, Samsung and so on. If you’re after something with a decent amount of CPU and GPU horsepower then you’re likely to be dragged into the depths of gaming notebooks (like those made by ASUS, MSI, Alienware and so on) even if you don’t want to game. So where do you go if you’re looking for something in between? Something that has style and is fairly slim but still has a fair amount of performance to allow you to be productive and game? Well PC Specialist are always a good place to start because you can customise just about any base notebook to have anything you want. Today we have a mid-range PC Specialist Cosmos II notebook in for testing and it looks like an epic all-rounder. With a dual core Haswell Core i5, an Nvidia GTX 850M 2GB graphics card, 8GB of RAM and a 1TB SSHD it has a great balance of performance, functionality and most importantly value. The design may be a little plain-Jane for the style conscious notebook buyer but if you’re happy for simplicity then this could be the ideal notebook for you. Below you can see the specifications of our PC Specialist Cosmos II notebook as we have it configured. You can change and configure just about every aspect of the Cosmos II if for whatever reason you need more or less of something.

Packaging & Accessories

PC Specialist are no strangers to building and shipping systems and notebooks to customers so I wasn’t surprised to see our review sample come in virtually bomb proof package. Not only is the notebook box well protected inside another outer box, but you also find the notebook comes with more foam protection inside the inner box.

The notebook box comes with a convenient carry handle, if you ever need to move all the parts around or send it back to PC Specialist for repairs then you should definitely keep hold of this.

PC_Specialist_Cosmos_II (2)

Included is a 120W AC adapter, 5600 mAh battery, UK power plug, a user guide, a driver & utility DVD and a Nero12 essentials trial version disc.

PC_Specialist_Cosmos_II (3)

The included adapter is manufactured by Chicony Power Technology and is good for 120W of output which is required for this notebook.

A Closer Look

The Cosmos II has a very clean design thanks to the matte black/dark grey uniform colour scheme, the deployment of a matte full HD screen is also nice – I for one hate glossy screens on a notebook.

PC_Specialist_Cosmos_II (19)

At the top of the screen we find a 2MP webcam with a microphone.

PC_Specialist_Cosmos_II (17)

Down below the screen we find the speaker system going across in a sound-bar like way.

PC_Specialist_Cosmos_II (16)

The keyboard is chiclet-style and is fairly sturdy although there is a little flex in the centre. The key travel is quite small so the typing experience is quite average but the spacing is fair enough and I like the full size backspace enter and shift keys.PC_Specialist_Cosmos_II (13)

The touchpad offers a left and right clock and a very large trackpad area. The gesture controls on the touchpad appear to be non-existent, I couldn’t get any swipe gestures working when I tested this notebook.

PC_Specialist_Cosmos_II (15)

The Cosmos II has a fairly thin profile at just under 2cm thick. The front has some LED lights and an SD card slot.

PC_Specialist_Cosmos_II (12) PC_Specialist_Cosmos_II (11)

The right hand side offers audio ports, a kensington lock, a USB 3.0 port, USB 2.0 port and a DVD drive.

PC_Specialist_Cosmos_II (10)

The left hand side has the charging port, ventilation outlet, a VGA out, gigabit ethernet, eSATA, HDMI out and a USB 3.0 port.

PC_Specialist_Cosmos_II (9)

The hinge on the Cosmos II is fairly strong and the laptop will go back about an additional 45 degrees from being in the upright position.

PC_Specialist_Cosmos_II (8)

The top is as plain as you can get, the plastic top has a brushed aluminium effect.

PC_Specialist_Cosmos_II (7)

The bottom has four rubber feet, a couple of battery locks and intakes for all the cooling.

PC_Specialist_Cosmos_II (6)

We opened the Cosmos II up to show you what the internals look like. You only have to take out two screws and slide the cover towards the battery area to access the internals. Inside everything is easily upgradeable: you can see the 2.5 inch drive, the wireless card, the mSATA slot, the SODIMM slots and even the CMOS battery are all easily accessible.

Networking Performance

Passmark PerformanceTest 8.0


The PassMark Advanced Network Test (which is part of PerformanceTest) is designed to test the data transfer rate between two computers both of which must be running PerformanceTest. One of the computers must act as the server and will sit waiting for a connection. The other computer acts as a client. It connects to the server machine and sends data to it for the duration of the test. You can download a trial version of PerformanceTest fromhere.

For this test we use the ASUS RT-AC68U wireless AC gigabit router and pump data from the test system or notebook through the ASUS router into our Intel Gigabit enabled test system. We connect to the ASUS router with a Cat6 cable when testing ethernet and wirelessly when testing WiFi performance.

Wireless (WiFi)



Noise, Power Consumption and Temperatures


The amount of noise produced by any computer is a vital consideration for most buyers, even gamers don’t really want a noisy PC because less noise is always better. We use an acoustic dBA meter held 2 feet behind our test system at idle and under load to get the idle and load noise levels for the system. For idle we allow the system to sit at the Windows desktop, for load we let Unigine Heaven 4.0 and Prime95 to loop together – we take the acoustic measurements 5 minutes into both of these scenarios.


Power Consumption

To test power consumption we measure the total system power draw during idle and load scenarios. For idle we allow the system to sit at the Windows desktop, for load we let Unigine Heaven 4.0 and Prime95 to loop together – we take the power measurements from the “Killawatt” AC power meter 5 minutes into both of these scenarios at the same point.



To test thermal performance we measure average CPU and GPU core temperatures during idle and load scenarios. For idle we allow the system to sit at the Windows desktop, for load we let Unigine Heaven 4.0 and Prime95 to loop together – we take the temperature measurements from within CPUID HWMonitor 5 minutes into both of these scenarios at the same point. For load we take the average of the maximum temperatures, for idle we take the average of the minimum temperatures.

PC Specialist’s Cosmos II is a brilliant versatile notebook. The phrase “it does what it says on the tin” is very apt here, there are no surprises or things hidden away you just get a well built and well configured notebook. The configuration we were sent is great, the combination of the dual core i5 processor and the Nvidia GTX 850M offers up solid gaming performance, snappy CPU performance and still gives you great battery life of over 4 hours under constant usage. This may not seem like much but from our testing this put the Cosmos II on par with a Samsung Ativ book “ultrabook” style notebook, except the Cosmos II has significantly more performance and screen real estate, and while we’re on the subject of the screen kudos to PC Specialist for the matte finish because it looks great! While the Cosmos II isn’t a “bargain basement” 15.6 inch laptop, like the kind you see on deal websites like HotUKDeals for £300~, it does offer outstanding value for money. For £700 (or just £649 using the eTeknix review link) you have a notebook that is capable of being a gaming notebook, a workstation, a media centre or even just something powerful to take with you to university or college. Being someone who recently came out of university I am quite sad I didn’t have something like this to get me through. It has enough storage and power for the kind of business applications we had to run (like ArcGIS) but it is also light enough at 2.7kg to be carried around without much difficulty.I also like the easy-upgradeability of the Cosmos II. As we mentioned you can take the bottom panel off with just two screws and you can easily upgrade or change the RAM, the 2.5 inch drive, the wireless card, the mSATA device and so on.

On the down side there are a few things that are worth mentioning. This notebook does attract finger prints on the bottom, although the top is fairly finger print resistant and that’s the part you see the most so that’s good. Secondly, the keyboard is a bit lacking in tactile feedback which is fairly common for most notebooks in the sub-£1000 price range. The key spacing on the keyboard is nice and they also offer lots of function keys which comes in handy but the keyboard could be better quality, LED backlighting would be a great option for them to add too. The trackpad also wasn’t the most inspiring, I found the lack of swipe gestures a bit of a pain in Windows 8.1 especially considering the display isn’t touch either. However, on the whole the trackpad was still fairly responsive and the mouse buttons offered a good tactile feedback. Again, like the integrated keyboard, you can’t actually change the trackpad which is a little disappointing seeing as everything else is customisable. I don’t like the inclusion of Bullguard antivirus software as it interferes with a lot of programs and is quite irritating. In my testing I found that Bullguard actually throttled the speed of the ethernet, once I uninstalled Bullguard ethernet performance more than doubled. However, in the system configuration tab PC Specialist do give the option to choose no AV software and you can easily uninstall it if you do end up getting a notebook with it on. The 1TB SSHD was perhaps the “weakest link” in the Cosmos II, even with an SSHD cache the fact it was only 5400 RPM meant performance was fairly average. Although I will say that the SSD cache does help with boot times, they were surprisingly fast easily taking less than 30 seconds, and generally speaking most applications felt like they were on an SSD. The only issues come when you’re installing, writing, editing or copying large files that exceed the SSD cache, then you’ll notice it is a 5400 RPM mechanical hard drive at heart.


  • Competitive pricing – nothing can match this at its price point
  • Good all rounder – gaming, productivity, everyday tasks
  • Fairly thin and light for a 15.6 inch notebook
  • Easily upgradeable
  • Highly customisable


  • Average keyboard and trackpad
  • The 5400RPM 1TB SSHD can be a bottleneck sometimes


  • Styling is fairly plain and minimalist

The PC Specialist Cosmos II is a powerful notebook “all-rounder” that is capable of meeting the needs of a modern PC user. Sensible component selection, great value for money, clean design choices and great performance make the Cosmos II a definitive choice for its price point.
