Reinstalling windows fixed it. No idea what was wrong with the original install

Reinstalling the graphics drivers fixed the SLI issue. Using a USB hub to work around the USB issue for now. I've discovered there's still power available through them.

Running a 6800k on an Asus X99 Strix with 2 GTX980s and a Samsung 960 Evo and a Samsung 840 Evo. I installed the 960 Evo today with only a single graphics card in because the second card covers up the m.2 port. Got windows running fine and everything. Then when it came time to put the second card and the 840 Evo back in I booted up and only one of my USB ports was working in windows. They all worked fine in BIOS. I can see that right after the post screen within a second of the windows loading screen appearing that the LEDs in my mouse turn off so it's definitely something in windows doing it. However I can get to device manager with just my keyboard in the one working USB port and see that it's recognising all the USB ports on the motherboard. I thought I might have run out of bandwidth but the 6800k has 28 PCIe lanes, I'm using x16 (1st 980) x8 (2nd 980) x4 (960 Evo) so I'm fine for PCIe bandwidth. I've tried different SATA ports for the 840 in case a different SATA controller was trying to use bandwidth that wasn't there. I've looked through my motherboard's manual and haven't seen anything about weird combinations of ports not working when maxing PCIe bandwidth, no odd POST code either. I've tried taking the second card and 840 Evo out but still the same problem. This leads me to think it's an obscure windows setting but I'm stumped. Edit: it also doesn't recognise my second 980, device manager reports it as a "Microsoft Basic Display Adapter" and the nvidia control panel doesn't see it.

Best option is probably a cheap gigabyte brix/zotac zbox with a vesa mount.

16GB would definitely help but if you can get a good deal on 8GB you can always get another 8 later for cheaper than you could buy 16 now.

Ah if you're gaming you definitely want something beefier then, definitely beefier than a GT 710 can offer. Those are generally intended to be cards for workstations that need extra monitors. You can find them with like 4 displayport ports which would otherwise be unusual on a card of that tier since people buying those cards don't have monitors with displayport. If you need gaming performance then the low profile 750 posted earlier is ideal. Maybe see if there's a low profile 950 about because that will be better. Ignore the "minimum power requirement" on the box of cards like that, go read actual reviews to see actual power draw. The box is just the manufacturer covering their ass.

What do you need the GPU to do that the iGPU can't? Only real use case I can think of is multi displays because the iGPU on an i5 3550 should be adequate for pretty much any video playback. If it's a HTPC then perhaps a tv tuner might be better suited to the PCIe slot?

I'm running a 4790k at 4.4GHz and 2 980s at 1.4GHz off a 750W with no issues. You'll be fine with 750W for 2 980ti's. I'm not sure where you're reading 600W for the GPU from but the 980 draws 160W under full load, a 980ti isn't much more.

Perfectly fine, I use a 750W psu for a 4790k at 4.4GHz and 2 980s at 1350Mhz

The N300 doesn't support wireless AC

It's a lot more likely that you misplaced the link cables than you never received them. There are 4 cables that can come out of a h100i pump, the 3pin pump power cable, the 2 corsair link Y splitter fan cables and the microusb link cable. First one powers the pump, the second two allow you to power and control 4 fans through corsair link and the microusb cable lets you connect the pump to the motherboard usb2 headers to use link to control things. You only need the last one to control the pump LEDs.

You can do it but be prepared for long load times because you'll only be reading from the server at a max of 1Gb/s due to the limitations of ethernet (unless you spent a couple grand on 10gig networking). However that's about 130MB/s which is still a good read speed for a hard drive so if you were loading your games from a hard drive not an ssd anyway it isn't quite so bad. While the bandwidth might not be too different the latency is definitely worse.

Haven't read all the details but this looks like a standard linear programming problem, look into the simplex algorithm.

60fps is only available in source quality.

The encoding is done on your CPU so you want to upgrade that to improve the encoding of your stream. If the pentium G3258 supports Intel Quicksync you can use that to use the integrated GPU on your CPU to do the encoding for you thus freeing the load from your CPU but only if you have the setting in the BIOS to disable the iGPU when a dedicated GPU is available is turned off. The G3258 is 2 core 4 thread right? If you want to run a quality stream you'll want at least 4 physical cores, preferably with hyperthreading. I'm assuming here you're using a reasonable bitrate such as 2000 and not anything crazy like 4000+. If you aren't already run your stream at 30fps and if you're stuggling at 720p you can drop down to 540p which is a happy medium between 480 and 720.
