What are the best gaming PCs under £800 to buy in the UK?
Our top pick for Gaming PCs Under £800 in the UK is the Veno Scorp Nemesis 4 Gaming PC (Ryzen 5 5500, RTX 3050 6GB, 16GB RAM, 512GB SSD).
The Veno Scorp Nemesis 4 Gaming PC suits a buyer who wants each main component named before buying: Ryzen 5 5500, RTX 3050 6GB, 16GB of 3200MHz DDR4 RAM, a 512GB NVMe SSD, a 550W PSU and Windows 11 Home, with a 2-year warranty that covers parts for 1 year.

The Veno Scorp Nemesis 4 is our top pick among gaming PCs under £800 because its listing names each main component: an AMD Ryzen 5 5500 processor, NVIDIA GeForce RTX 3050 6GB graphics, 16GB of 3200MHz DDR4 RAM, a 512GB NVMe SSD, a 550W PSU and Windows 11 Home, with a 2-year warranty that the listing splits into 1-year parts and 2-year labour. For a stated 600W 80+ Bronze PSU and 2 years of parts and labour cover, the XUM CMP 510 is the alternative. For a bundle with a monitor, keyboard and mouse, the Vibox VI-42 lists all three, with integrated graphics that its listing notes are not a graphics card.
This guide compares six gaming PCs from Veno Scorp, XUM, STGsivir, EZZTECH and Vibox, using what each listing states: processor, graphics, RAM, storage, power supply, operating system, what is in the box and warranty. All six state 16GB of RAM. Four name RTX 3050 graphics and two state integrated graphics, and stated SSD sizes run from 256GB to 1TB.
Buying guide
What should you look for in Gaming PCs Under £800?
1Graphics: four listings name RTX 3050 graphics: the Veno Scorp Nemesis 4 (NVIDIA GeForce RTX 3050 6GB), the STGsivir (GeForce RTX 3050 6GB GDDR6), the XUM CMP 510 (RTX 3050 in the bullets, GeForce RTX 3050 8GB in the product information) and the EZZTECH (RTX 3050, no memory stated). The XUM Legend states Radeon Vega 7 integrated graphics and the Vibox VI-42 an integrated Radeon Vega 8, which its listing notes is an integrated graphics chip, not a graphics card.
2Processor: the Veno Scorp Nemesis 4 and the XUM CMP 510 list a Ryzen 5 5500, the XUM Legend a Ryzen 5 5500GT, the STGsivir a Ryzen 5 3400G and the Vibox a Ryzen 3 3200G Quad-Core. The EZZTECH says Intel Core i5 without a model number.
3Storage: the Veno Scorp states a 512GB NVMe SSD, the XUM CMP 510 a 512GB SSD, the STGsivir a 1TB SSD and the Vibox a 1TB SATA SSD. Two listings pair an SSD with a 1TB HDD: the EZZTECH (512GB SSD) and the XUM Legend (256GB NVMe SSD).
4Power supply: three listings state a wattage: a 600W 80+ Bronze PSU on the XUM CMP 510, a 550W PSU on the Veno Scorp and a 500W PSU on the XUM Legend. The STGsivir, EZZTECH and Vibox listings do not state one.
5What is in the box: the Vibox VI-42 lists a monitor (22" in the title, 21.5" in the bullets), keyboard, mouse, mouse mat and headset. The EZZTECH describes a tower-only configuration for buyers who already have a monitor, keyboard and mouse. The Veno Scorp, both XUM and the STGsivir listings do not say whether any of these is included.
Our process
How do we choose our picks?
We don’t lab-test products ourselves. Instead we synthesise current Amazon UK listings and published specs into clear, honest recommendations. We earn a commission if you buy through our links, but that never changes which products we rank.
Current UK availability
We check each pick against live Amazon UK catalogue data rather than last year’s model lists. Stock moves fast, so a listing can sell out after we publish.
Published specs
We compare manufacturer specifications so each pick is right for a real budget and use-case.
UK-specific fit
We factor in UK voltage and plug/fitting standards — details that generic global lists miss.

Editor's Note
The Veno Scorp Nemesis 4 names its processor, graphics memory, RAM speed, SSD type, PSU wattage, Windows edition and split warranty terms. The EZZTECH names neither its Core i5 model nor a PSU wattage, and the STGsivir and Vibox also state no PSU wattage. The Vibox and the EZZTECH are the only two listings that say whether a monitor, keyboard and mouse are included.
Our Take
As a default, the Veno Scorp Nemesis 4: Ryzen 5 5500, RTX 3050 6GB, a 512GB NVMe SSD, a 550W PSU and Windows 11 Home, all stated on the listing. For 2 years of parts and labour cover and a 600W 80+ Bronze PSU, the XUM CMP 510. For a monitor, keyboard and mouse in the same box, the Vibox VI-42, whose listing states integrated graphics.

Frequently asked questions
Do gaming PCs under £800 come with a monitor?
Of the six here, the Vibox VI-42 is the only listing that states one is included: a monitor given as 22" in the title and 21.5" in the bullets, with a wired RGB gaming keyboard, wired RGB gaming mouse, mouse mat and wired headset; its listing notes that its Radeon Vega 8 is an integrated graphics chip, not a graphics card.
