Before my wife gets home. Help with Gigabyte GeForce GTX 1660 Super OC

[antspants]

I swear I read that they were compatible, I swear. I just got delivered a Gigabyte nVidia GeForce GTX 1660 Super OC for my ROG Asus Maximus VI Formula and nothing is responding. I get the boot beep and that is where it stops. Can’t see bios, monitors aren't starting.

My PC stats haven't changed for years so whatever is listed below is what I have (less the new GPU)
My wife is going to get home, computer in pieces. Not that it’s anyones problem but my stats haven’t changed for a reason, she see’s this and she is gonna freak out, especially if it doesn’t work. A nervous lol

Please, anyone?

I thought PC stats ere listed on profile? They’re on my pc, will have to try find documentation, sorry.

ASUS Maximus VI Formula
Intel Core i7 4770K
Noctua NH-D14 CPU Cooler
Corsair 32GB (4x8GB) DDR3 CMY32GX3M4A1866C9 1866MHz
Silverstone 1500w

I placed the GPU into the first slot (closest to the CPU)
The power supply is a Silverstone 1500w (ST1500) Modular,
I have 4 cables with 8 pins (6+2) each cable, they read as follows;
6+2 Pin (PCI) +12v5 Express
6+2 Pin (PCI) +12v6 Express
6+2 Pin (PCI) +12v7 Express
6+2 Pin (PCI) +12v8 Express
Each cable has a corresponding entry point on the power supply. I don’t know which cable I should use and I can’t find any documentation to help me find out. 

I have unplugged everything except the mouse and keyboard (hdd’s and ssd’s are still connected)
Only one monitor is connected to the GPU (I have 6 monitors) 
The only thing I haven't done is load bios defaults to disable the onboard graphics, because I cant get into the bios.

Ignore this thread, sorry. A learning experience on Non bidirectional HDMI to Displayport cables. Looks like I need some adapters.

But I would like to know if anyone can help; which of these should I be connecting to the geforce gtx 1160 GPU?

Check the documentation for your PSU to be certain, but it probably doesn't matter which of the PCIe power cables you use, as long as all power connectors on the GPU have power.  A 1500W PSU is *HUGE* for the hardware you have listed above, so it's very unlikely that you would be running into power limits with it.

The label on the PSU case should tell you if it's a single or multi-rail PSU, how the various outputs are split across the rails, and what the limits are.  That's about the only thing where I could see it making a difference which outputs you use, but it still seems unlikely that it would matter with such a large PSU (unless you have a bunch of other high power stuff that's not mentioned here).

Hi! Not a lot of documentation, hence my not knowing which cable to run from PSU to GPU.

Online says the PSU is a single +12V rail design. I suppose my only concern is throwing too much power into it. And as I don't know anything after 9 years or so living with the same computer components, I've lost track and find it harder to keep up in my older years.

The PSU was a gift from a guy I helped in a fellowship one day. He was a REP and asked me if I was into computers. As I built them back then (when it was sooo much easier) I said yes. He opened his boot and gave it to me, which back then had a hefty pricetag. So I said thanks, was grateful and ran home to try hurt myself with it.

Other than 6 monitors 5 HDD's and 6 SSD's, there are 4 USB hubs with crap coming out of every hole. But like I said, the PSU was free! So bonus plus overkill. I suppose if my refrigerator motor gives way I can always plug it in lol
Hey, Murph_9000, thanks for responding, cheers

[antspants]

if this helps?

The list starts with unprecedented eight +12V rails each capable of up to 25A (1320W at 120A across its eight +12v rails)
A maximum load potential of up to 1600W across the entire unit
Active Power Factor Corrector
4 PCI-Express 8-pin cables and four PCI-Express 6-pin cables

You can't "throw too much power into it".  The PSU provides 12VDC and it's up to the card to pull as much current as it desires for any given moment in time.  I.e. the current and power is pulled and controlled by the GPU.  The PSU reacts to the demand by working harder to keep the voltage steady at 12V as the load tries to drag the voltage down.

Ahh ok, understood. Thanks again, very much. Cheers
