I have just bought Lenovo H50 90C1 desktop system. It has one PCI Express slot, unmarked (does not say 3.0). There is no name on the motherboard other than Lenovo, it is an internal cheap motherboard without any specs. Neither the manual nor the website, nor the sales know anything about which PCI Express version this slot is, 2.0 or 3.0. Device Manager also does not say what version.

I HAVE to know, whether this thing is PCI Express 2.0 or 3.0.
