Question

Iron

Good time of the day! There is a system with a motherboard asus p7p55d percent. i5 550 gtx 460 video card, I want to replace it with a more powerful one. After looking at the video cards in the shops of my city, they mostly have a pci-e 3.0 connector. What are the consequences after replacing the video card with this connector? Friends say that there is nothing to fail, but on the Internet they write that it is possible. Help me please.

Answer 1

Interface versions are backwards compatible. Maybe the card will not work at 100% of its capabilities. But most likely you won't even feel the difference between version 2 and 3.

Answer 2

Yes, put it in calmly. As far as I remember, the voltage there is the same. But it is better to change the motherboard at once, because this one is already incredibly outdated.
In general, all you need is to compare the voltage characteristics of these slots. You can also ask overclockers.ru. If they say yes, then you can.
