Cyberpower Infinity X55 Pro Gaming PC Review

Final Thoughts


The Cyberpower Infinity X55 Pro’s default configuration is currently available for £999 including standard shipping. To determine a system’s value proposition, we endeavour to compile an identical self-build and compare the price. This allows us to analyse the fee (if any) that a system integrator is choosing is charge customers for its services.

  • Case: Corsair 600C = £119.99
  • Motherboard: MSI Z170A SLI Plus = £112.63
  • Processor: Intel Core-i5 6600K = £199.99
  • Processor Cooler: Corsair H55 = £49.99
  • System Memory: Corsair 8GB (2x4GB) DDR4 LPX 2400MHZ = £37.48
  • Main Boot Drive: Corsair Neutron XT 240GB = £77.08
  • Additional Storage Drive(s): Western Digital 1TB 7200RPM = £40.99
  • Graphics Card: XFX AMD Radeon R9 390 8GB = £249.99
  • Power Supply: Corsair VS 650W = £46.92
  • OS: Windows 10 Home = £75.99
  • Extras: White LED Strip = £9.91

Once totalled up, the self-build costs £1020.96 which is an increase of £21.96. As a result, the Cyberpower system offers greater value and comes with a comprehensive 3-year warranty to boot!


The system’s colour-coordinated neutral black theme evokes a premium feel and should appeal to a wide range of tastes. For example, the matte black Corsair H55 pump contrasts extremely well with the glossy XFX backplate and DDR4 memory. This level of synergy throughout the build creates a sublime finish. Furthermore, the Corsair 600C’s inverted design looks spectacular and allows for a cleaner finish due to the power supply cover. Not only that, the chassis’ doubled hinged windowed side panel and robust construction exemplifies the build’s no-compromise approach. Of course, a cheaper case could have been deployed to cut costs and focus on the core components. However, it wouldn’t have left a good first impression or made the end-user feel proud of their investment. Aesthetically speaking, the system is highly elegant and the perfect choice for consumers who dislike extravagant colour combinations.

Cyberpower has meticulously selected from a huge inventory to form a very balanced and reliable system. The MSI Z170A SLI Plus motherboard is an affordable option with enough functionality to please the average user. It might seem a little puzzling to choose an SLI focused product given the system’s R9 390 graphics card. However, it’s an essential feature just in case you want to opt for a dual GPU NVIDIA setup in the near future. It’s important to acknowledge the motherboard’s other key features including USB 3.1, Turbo M.2 and more instead of fixating on the SLI name. The Corsair H55 all-in-one CPU cooler is capable of taming overclocked Skylake processors without becoming too loud. Throughout the testing procedure, I didn’t encounter any pump whine or sudden RPM changes. It’s certainly not as quiet as high-end air coolers like the Noctua NH-D15S but this shouldn’t matter unless you want a completely silent rig. Personally, I’d prefer to see Cyberpower include the Corsair H80i GT due to the textured tubing and LED block. Although, it would increase the price and detract from the subtle black styling.

The 4.5GHz overclock remains well within thermal limitations and there’s additional headroom to achieve a 4.6GHz frequency, but it’s sensible to air on the side of caution just in case some users use their PC in a warm environment during summer. The system’s 8GB DDR4 memory isn’t the fastest on the market but it’s more than enough for gaming purposes right now. In the future, 16GB might become the standard but it’s easily upgradable even by users without technical expertise. In terms of storage, the boot SSD is capable of excellent read/write speeds and surpassed the majority of SATA drives on the market. Additionally, the 240GB capacity is large enough to store the OS, a few games and applications without worrying about a lack of space. On another note, the secondary mechanical drive is designed for storing games with huge file sizes like GTA V.

When it comes to gaming performance, the R9 390 is fantastic and competed against the GTX 970 exceedingly well. This allowed the system to attain a fluid frame-rate on a variety of visually demanding games. It’s even capable of powering a 2560×1440 screen without major frame-drops occurring on a regular basis. The 8GB frame buffer also makes it a more suitable choice than the GTX 970 for VR equipment. The R9 390 offers a superb price to performance ratio and greatly enhances the system’s appeal.

The Corsair VS 650W power supply is rated at 80 Plus White efficiency and has enough power to support dual graphics card solutions if you decide to go down that upgrade path. Unfortunately, its non-modular design can cause some complications in the cable management department. The cabling on the front visible windowed section is flawless and worthy of praise. Sadly, the opposite side looks quite messy and there’s a huge array of cables scattered around the chassis. Upon first inspection, this isn’t ideal but you have to take into account the Corsair 600C’s narrow room for cable management. Personally, I think it’s fairly decent and there’s evidence of solid workmanship. For example, the case’s top panel cabling is kept away from the PSU’s power connectors. Also, a large number of zip-ties have been used to hold various cables in position. What really matters is the area which the end-user looks at every day on their desk. This section is extremely clean and I’m fairly confident that it will leave a very positive first impression.


  • Attractive Cyberpower branding
  • Balanced component selection
  • Excellent packaging
  • Fantastic temperatures
  • Great customer service
  • Professionally overclocked to 4.5GHz
  • Sophisticated styling

“The Cyberpower Infinity X55 Pro is one of the best sub-£1000 packages I’ve seen due to the unique aesthetic design and impeccable performance numbers. Furthermore, it’s actually cheaper than an identical self-build and offers a stunning price to performance ratio.
