Backpack VR computers are starting to become a trend. Zotac added a backpack to one of its Zbox mini-computers, MSI announced a backpack PC, and HP launched its Omen gaming line that will include soon a VR backpack PC as well.

ZDNet reports the backpack PCs are a solution intended to keep users connected to the massive graphics and processing power required for experiencing virtual reality (VR). At the same time, the backpack PCs ensure that users remain mobile enough to perform movements required by the VR scenario in which they are immersed.

This concept is not really new. Some lesser known vendors have experimented with the concept before. However, now the idea of backpack VR PCs comes under the attention of major brands in the industry.

For instance, at this week's Computex trade show in Taipei, Taiwan, MSI will unveil its Backpack PC equipped with high-end components. The unit will come equipped with Nvidia GTX 980 graphics card and Intel Core i7 processor.

According to The Verge, backpack computers are a trendy niche including very specific kind of machines. They are catering to power tethered headsets for virtual reality (VR).

More attention is grabbing the upcoming backpack PC from HP, that is part of the premium Omen X line. It is expected that the computer manufacturer will start testing, in about a month, the first demo units.

The specs of the upcoming HP Omen X backpack PC are somehow similar to other VR-ready desktop PCs. The unit will be powered by an Intel Core i5 or i7 processor and will come equipped with up to 32GB of memory. The graphics card model is still unknown.

The unit will fit the equivalent of a slender backpack and will weigh just under 10 pounds. Two batteries that power the graphics card and the CPU separately will be incorporated in the waist belt. The unit will also feature a pair of fans that will dispel heat.
