The Ultra 79 XTX Gaming PC out of cyber power is a high-end system aimed at those looking for serious gaming performance. Priced at £3249 it’s certainly not a budget option. AMD components are used for both the CPU and the GPU, and the offered CPU is the Ryzen 9 7900X3D with AMD’s 3D V-Cache technology. If the performance of the previous generation Ryzen 7 5800X3D is anything, then we should see great gaming performance here as well. Combining the aforementioned CPU with the top-of-the-line RX 7900 XTX graphics card, the Gigabyte Gaming OC model to be precise, should ensure this system is able to deliver some serious framerates when gaming.


  • CASE: Corsair 5000X iCUE RGB Gaming Case – Black
  • Processor: AMD Ryzen 9 7900X3D
  • RADIATOR: Corsair iCUE H150i RGB ELITE 360mm liquid cooler
  • SSD: 2TB WD Black SN850X M.2 NVMe PCIe SSD
  • MEMORY: 32GB (2 x 16GB) DDR5/5600MHz Corsair Dominator Platinum RGB memory
  • PSU: Corsair RM1000e 1000W 80+ Gold Modular Gaming PSU
  • VIDEO: AMD Radeon RX 7900 XTX 24GB

The Ultra 79 XTX’s design definitely has a gamer style, but it’s classy and minimalist thanks to Cyberpower that matches the black variant of the Corsair iCUE 5000x RGB case. It offers fully tempered glass with heavily tinted panes all around. Cyberpower added custom branding to the front in the form of their own logo on a small plaque just above the Corsair logo. Three RGB fans are integrated in the front of the case and can be controlled and synchronized with Corsair’s iCUE software.

The cooler chosen by Cyberpower is the Corsair H150i RGB Elite 360mm AIO. The cooler was mounted on top of the case, with air being exhausted through the cooler with three non-RGB 120mm Corsair fans. However, the CPU block/pump is fully RGB and can be customized using Corsair’s iCUE software. The cooler looks great overall, but the inclusion of Corsair RGB fans would help take it to a higher level.

The star of the show is AMD’s new Ryzen 9 7900X3D processor. It features 12 cores and 24 threads running on AMD’s Zen 4 architecture. The 7900X3D has a base clock of 4.4 GHz and a boost clock of up to 5.6 GHz and features AMD’s 3D memory caching technology, which is said to ensure excellent gaming performance.

The system is all Team Red with the Gigabyte Radeon RX 7900 XTX Gaming OC GPU. This card has 24GB of GDDR6 memory and should have absolutely no trouble smashing any game you throw at it.

If the PC is running both an AMD CPU and GPU, this should open up the possibility of using AMD’s Smart Access Memory technology, which basically just allows the CPU to use all memory found on the GPU directly to address – the same as enabling changeable BAR on a non-AMD exclusive system.

The memory found in the PC is Corsair Dominator Platinum RGB. This is of course DDR5 and runs at 5600 MHz. One small point I do have to make, though, is that we think it would have been better to ditch the fancy RGB memory in favor of faster 6000MHz non-RGB RAM. While I’m guessing a lot of gamers love a bit of flashy RGB, they also love frames per second.

I can’t complain too much though as CyberPower obviously offers the option to fully customize the PC on their website and you can opt for 32GB of Corsair Vengeance RGB memory running at 6000MHz and you still get RGB for that a very small additional charge.

The motherboard chosen by Cyberpower is the MSI MPG X670E Carbon WiFi. This thing has all the bells and whistles that make it a solid choice for a system like this. It’s obviously a DDR5 board that supports up to 128 GB of RAM in total. It has 4 M.2 slots, which makes adding storage later on quite easy. Besides the dedicated CPU and pump fan headers, it has 5 case fan headers. This is a decent amount to cover when additional fans are added. Also, this board looks good in my opinion. The shielding or “armour” for the M.2 slots and VRMs looks really clean and just helps keep things looking tidy.

The system contains only one drive. It’s the Western Digital 2TB SN850X M.2 SSD. Two terabytes is quite a lot of storage space and should cover you for installing some games. The read and write speeds on this drive are fast enough for everyday use, and after installing the 10 games I used for benchmarking, I had plenty of room for other things. Also, as I mentioned in the motherboard specs, it’s easy enough to add some more memory later if you want.

The PC is powered by the Corsair RM1000e, and as the name suggests, it’s a 1000W machine with an 80+ gold rating, while also being fully modular. It has enough juice to handle the current spec and should be good for any upgrades made to the system over its lifetime. There’s no native 12VHWR connector on this power supply, but Corsair sells an adapter for £20 to have you covered if you ever wanted to switch the GPU to a model that requires the new PCIe Gen5 connector.

Before we look at how this system performs during our benchmarks, I just wanted to commend CyberPower PC for the excellent cable management. Everything is really tidy and the cable management options offered by the Corsair 5000x RGB’s case have been fully utilized. I was really pleased to see this as it’s those little touches that add to the overall experience of buying a pre-built gaming PC.
