Can Lenovo Qitian install a full-height graphics card?

Your machine is relatively old, so you can add it, but I personally don’t recommend it. The first condition for adding a graphics card to a desktop computer is that there is a graphics card slot (PCI-E 16X, etc.) on the motherboard.

The graphics card can be replaced, but the power supply does not look like a standard size. You can open the side cover and take a look. If you are not sure, just send a photo.

This machine can be installed with various current mainstream graphics cards. It depends on how much you have to spend and whether the power supply is sufficient. Adding memory will greatly improve the performance. If you do not add memory, even upgrading the graphics card will help the performance. Still limited.

In short, if you want to install a graphics card on Lenovo Qitian M425, it is recommended to first understand the constraints of chassis space and power supply, choose a suitable graphics card, and ensure that the graphics card has good heat dissipation performance to avoid affecting the machine's performance. stability and longevity.

Regarding the processor, it can be paired with up to i7 8700. It is not recommended to use 8700k because the original heat dissipation of Lenovo may not be able to suppress the 8700K. In terms of memory, it is okay to add one 8G 2666, or you can buy two. 8G 2666, to replace the original 4G graphics card, you can only choose a low-power independent graphics card, p620 is acceptable.

Lenovo Qitian m425 is fine if it does not exceed 150. I plan to install a memory stick and a gtx960, so I have to replace the power supply, but after taking it apart, I found that the shelf where the hard drive is placed blocks a lot of circuit and interface power consumption. The half-length graphics card GTX650 is estimated to be 75W, and the power supply can drive it. No problem, it is recommended to replace it with a GTX750 TI, power consumption is the same.
