What GPU brand comes in the G649

The brand of GPU will differ based on availability of GPU's during the time of build and it won't be something that you'll be able to determine in advance. This is one of the disadvantages that a pre-built system has over a custom built, being that you often do not have access to specific component selections that you may prefer. That said, one major advantage of pre-built systems is that you do not need to endure the warranty service of the GPU manufacturer but rather the warranty of the system manufacturer (in this case, PowerSpec). If something were to happen with your GPU, it would be covered under the PowerSpec system warranty (plus additional warranty coverage depending on which plan you choose to purchase if any).

Regardless of the included brand of RTX 3080 Ti, all of the ones we've utilized in production perform identically at stock settings and have been tested extensively for compatibility both in terms of performance as well as reliability. If you have any further questions, feel free to let us know.
