Hello

I have a basic H110 micro-atx board ( Asus H110m-D ) and running an i5 6500. In the motherboard specification under "Expansion Slots" tab, these are shown:
1 x PCIe 3.0/2.0 x1 (x16 mode)
2 x PCIe 2.0 x1

My questions are:
1. I know the PCIe 3.0/2.0 x1 (x16 mode) is the expansion slot for my GPU. But what do the other two PCIe 2.0 x1 do? I mean for what they are used for? and what's the maximum data transfer bandwidth of these slots?
2. I have just ordered a GTX 1060 6G card ( EVGA SC edition ). Is this a good choice for 1080p ULTRA 60FPS gaming?
3. Will this card be fully compatible with my motherboard and will I be experiencing any bottleneck? ( I have 16GB DDR4 2133 Mhz Memory & a 128GB kingston UV400 SSD)
4. I know that I have a budget motherboard when compared to other components... but is this really a issue? will the GPU & processor work at its full potential in this motherboard when compared to other high end motherboards? it is really a silly question! but I can't calm my nerves until I get answers!

1. They're for other expansion cards. Could be a WiFi adapter, for example. A PCIe 2.0 x1 connection has a maximum usable throughput of 500 MB/s in each direction.

2. Yes.

3. Yes, and it fits well with the CPU etc.

4. It doesn't affect performance at all, it just limits how many ports and features you have access to.

As said the other provided Pci-e ports at x4 or X1 Pci-e lanes can be used for other Pci-e based hardware cards.

Sound cards, Usb 3.0, 0r 3.1 expansion cards to add more hi speed usb ports to your system.
Digital Tv cards for free view access.
Expansion cards to add extra Sata data ports, connect more HDD, or SSD drives if needed.

GTX 1060 cards are ok, but don`t expect to be running some games at 1080p resolutions and above with all of the graphical settings and FX`s options in games to all be set to Ultra or very high settings all of the time.


Budget or cheaper priced motherboards to reduce the price often have less expansion options, or are limited by the number of interfaces or ports found on them to connect other devices to the motherboard.

They will also have very little bios features and options, menu selection to do with hardware setup, or if you plan to overclock components such as the cpu or memory connected to the motherboard.

The more you pay the more possibility and expansion options will be provided for extra hardware you wish to add to the system as a whole.

What's the throughput of PCI Express 3.0 X16 slot? Just Curious!
