Are the PCIe 1x compatibly with PCIe 2.0 or 3.0 or PCI 2 and it doesn't drain power or something?

Hello, so this is my situation... I have a asus z87-plus motherboard with three PCI spots left, and I wan't to connect a PCIe 1x into them and they are all either 2.0 16x or 3.0 16x I believe, so my question are can I connect the PCIe 1x into them WITHOUT any trouble or loosing of performance/power. I know that they can connect from other threads but they were vague on whether or not I loose anything from it, One source told me it depends on motherboard so i thought i'd ask you here before i contacted Asus. Also be aware that my computer knowledge isn't top notch so some of the information about the PCIe might be wrong. ^^

The PCIe 1x i wanna connect:

The manual PCI slots(PS: the open PCI slots i have are 5, 6 and 7:

Another part of the manual on PCI slots that i did not understand and i think this might be relevant:

The whole Manual if you wanna read it for youself:

I think that should be all the information you need and i hope i get a answer soon, thanks in advanced for your answer if you do. ^^

The CPU provides the PCIe connection to the graphics card, and with a Z87 chipset that can be split to two slots. Those slots are the top two full-size PCIe slots. All the other slots are handled by the chipset, and an x1 card can go in any one of them. It won't make any difference.

It's all good. You will not lose any performance by installing a wifi card. If you have a gpu installed, which I'm guessing you do, use slot 4. Keep the airflow unimpeded around the gpu as best as possible.

Slot 4 is busy, that's why i'm unsure, and because i heard that it might make my gpu loose perfomance if i use it on a larger slot that wasn't ment for PCIe 1x I have GTX 780 as GPU and it covers the first slot and it uses 2nd and 3d and i have a capture card on slot nr 4. I'd rather get USB if i loose performance. ^^

In that case, you will be better off with a usb dongle for wifi. The performance difference should not be noticeable if you have a decent router. You might also want to look at a second router as an access point.

Thank you, I just needed to be sure before I ordered the wifi card. :) How sure are you however? You might not be 100% but I just want more stuff to make me feel more comfortable about my decision.

I didn't say there is anything wrong with using 7, I just said in this instance I think a dongle would be a better solution. I personally don't like using a full size slot for pci 1. JMO

Thanks for the answers guys. :)

Also Mark, I don't mind using a full size slot for PCIe x1 as i wont get any new PCI cards for quite a while and if i ever do SLI than it won't be before in a year or two and than i'd live in another place were I could go wired anyway. ^^
