Here is an imgur link to a big screenshot with additional info about my PC:

my best guess would be it's because your gpu is not really working that hard because of your lowish screen resolution 1920x1080 (1080p), i'd think where you saw 200+watts was because they were running at a much higher screen resolution maybe even as high as 4k 3840x2160.

sorry didn't fully read your original post and thought you were just asking about the power draw difference.
ok so just had a look at your image info and from what i can see it looks like your running a pci-e 3.0x16 card on a motherboard with pci-e 1.1x16 slot.
gpu-z screen shot, bus interface info.
so that is where your losing your performance that your card is capable of to other pc's you've seen they probably are running ona machine with a faster pci-e bus slot using version 2.0 or 3.0.
more info on pci-e lanes and speeds here :- http://www.trentonsy...ress-interface/
Base Clock Speed: PCIe 3.0 = 8.0GHz, PCIe 2.0 = 5.0GHz, PCIe 1.1 = 2.5GHz
Data Rate: PCIe 3.0 = 1000MB/s, PCIe 2.0 = 500MB/s, PCIe 1.1 = 250MB/s
Total Bandwidth: (x16 link): PCIe 3.0 = 32GB/s, PCIe 2.0 = 16GB/s, PCIe 1.1 = 8GB/s
Data Transfer Rate: PCIe 3.0 = 8.0GT/s, PCIe 2.0= 5.0GT/s, PCIe 1.1 = 2.5GT/s
ok just did a check on that motherboard and according to this :- https://www.asus.com...XIMUS_VII_HERO/
it uses pci-e 3.0 same as the card so i'd guess you have set something in the bios that is slowing the bus down to pci-e 1.1 speeds.
and that's where i'd look first either that or the motherboard or card is faulty and running at pci-e 1.1 speeds, don't know which is which from the gpu-z screenshot just know for some reason your only getting pci-e 1.1 speeds if it is correct. "PCI-E 3.0x16@x16 1.1" should say "PCI-E 3.0x16@x16 3.0"
