Octominer X8 ULTRA PLUS

In our opinion, the Octominer X8 ULTRA PLUS is the ideal choice for most crypto miners, especially those with more powerful GPUs who want to get the most bang for buck where space is limited.

The X8 is slightly cheaper than the X12, comes with a fantastic spec as standard and a wider triple slot width for GPUs (65.00mm GPU To GPU), meaning these will cover even the largest of cards such as the more powerful Nvidia 3080s and 3090s.

We use the X12ULTRA and X8ULTRA PLUS cases for the prebuilt GPU mining rigs we sell and can confidently say that an 8 x 3090 X8 ULTRA PLUS will hit nearly 1,000 MH. The cooling capability of the X8 ULTRA PLUS is exceptional and the case is significantly narrower than the X12. Its slim, sleek design will fit in almost any space.
