Onyx 270K RX 9070 XT Gaming PC

Onyx 270K RX 9070 XT Gaming PC – Built in the UK

The Onyx 270K is a high-end 1440p and 4K gaming PC for demanding games, streaming and video editing, with 16GB of VRAM.

As a 270K RX 9070 XT gaming PC, the Onyx 270K is built for enthusiasts, content creators and power users who want VRAM capacity and storage speed to matter as much as raw frame rates. The Intel Core Ultra 7 270K Plus has 24 cores (8 performance and 16 efficiency) with a maximum turbo of 5.5GHz. The AMD Radeon RX 9070 XT carries 16GB of GDDR6 video memory, a real advantage over 12GB cards when you work with large textures, 3D assets or high-resolution video.

The Onyx 270K is built on an Intel Core Ultra 7 270K Plus processor and a Gigabyte Z890 EAGLE WIFI7 motherboard, with an AMD Radeon RX 9070 XT 16GB graphics card, 32GB of DDR5 6000MHz memory and a 1TB Crucial T705 PCIe 5.0 NVMe SSD. It is cooled by a Corsair Nautilus 360 RS ARGB 360mm AIO, powered by a Corsair RM1000e 1000W 80 Plus Gold PSU and housed in a Corsair FRAME 4000D RS ARGB case. It comes with Microsoft Windows 11 Home 64-bit (genuine, pre-installed) and a 3-year parts and labour warranty.

1TB PCIe 5.0 NVMe – Exceptional Storage Performance

The 1TB Crucial T705 delivers sequential read speeds of up to 13,600MB/s and write speeds of up to 10,200MB/s over a PCIe 5.0 NVMe interface. It holds the operating system and your applications. The Gigabyte Z890 EAGLE WIFI7’s PCIe 5.0 M.2 slot lets the drive use that interface in full.

Radeon RX 9070 XT – 16GB GDDR6 for 1440p and 4K

The AMD Radeon RX 9070 XT has 4,096 cores and 16GB of GDDR6 video memory, and is rated at 304W. It targets 1440p ultra and 4K high settings in demanding titles. The 16GB frame buffer also gives headroom for large textures, 3D assets and high-resolution video work. The card provides 3 x DisplayPort 2.1a and 1 x HDMI 2.1b outputs for up to four monitors (the layout may vary by card brand).

Corsair FRAME 4000D RS ARGB – Black Mid-Tower with Tempered Glass

The Corsair FRAME 4000D RS ARGB in black is a mid-tower with a tempered glass side panel. Three pre-installed RS120 ARGB PWM fans provide airflow and lighting out of the box. The Corsair Nautilus 360 RS ARGB 360mm AIO cools the CPU.

Wi-Fi 7, USB4 & Z890 Connectivity

The Gigabyte Z890 EAGLE WIFI7 is an ATX board on Intel’s Z890 chipset, and the Core Ultra 7 270K Plus on it is overclockable. Built-in Wi-Fi 7 with Bluetooth 5.4 and a Realtek 2.5GbE wired LAN port cover networking, and the board has Realtek 7.1 HD audio. The rear I/O includes a USB4 Type-C port with DisplayPort output, a further Type-C 10Gbps port and two Type-A 10Gbps ports. The board has four M.2 slots (one PCIe 5.0 x4 used by the T705, three free PCIe 4.0 x4) and four SATA 6Gb/s ports for future storage expansion. The 1000W Corsair RM1000e leaves plenty of headroom for the RX 9070 XT’s 304W rating under sustained load.

How fast is the Crucial T705 SSD in the Onyx 270K?

The 1TB Crucial T705 reads at up to 13,600MB/s and writes at up to 10,200MB/s over PCIe 5.0 NVMe. The Z890 EAGLE WIFI7 has a PCIe 5.0 x4 M.2 slot for it, so the drive uses that interface in full. It gives quick boot and load times and has room for a large game library and project files.

Can I upgrade the Onyx 270K later?

Yes. The motherboard has three free M.2 slots (all PCIe 4.0 x4) and four unused SATA 6Gb/s ports for extra storage. Two of the four DIMM slots are empty, so memory can grow beyond 32GB, up to a maximum of 256GB. The 1000W power supply leaves headroom for added drives.
