Gaming desktop for mainstream players

The OMEN Obelisk 875 is a tower system built around a six-core Intel Core i5-8400 processor that runs at 2.8 GHz and can reach 4 GHz. Sixteen gigabytes of DDR4 memory at 2666 MHz and a dedicated NVIDIA GeForce GTX 1060 with 6 GB of GDDR5 give solid 1080p frame rates in current titles. Windows 10 Home is pre-installed.

Dual-drive storage with NVMe speed

A 512 GB NVMe SSD handles the operating system and favourite games for quick boots and level loads. The 1 TB hard drive adds bulk capacity for media libraries and less-played titles. The board supports up to 32 GB of DDR4, so memory headroom exists for heavier multitasking, while the 500 W supply limits further graphics upgrades.

Tool-less chassis and modern I/O

The black tower opens with a button press for straightforward internal access. Front I/O provides a 3.5 mm combo jack, microphone input and two USB-A 3.1 ports. The rear panel adds five more USB-A 3.1 ports, one USB-C port, HDMI, three DisplayPort outputs, DVI, gigabit Ethernet and analogue audio jacks. Wi-Fi 5 and Bluetooth 4.2 handle wireless duties.
