Recently purchased an EVGA Supernova 1200W P2 to replace a Corsair HX750 PSU. I also purchased another EVGA GTX 780 Ti SuperClocked to add onto my system.
 
The rest of my specs are:
 
Intel Core i7 2700-K
EVGA Z77 FTW
EVGA GTX 780 Ti SuperClocked - SLI
Corsair Dominator XMS3 2 x 4GB
Intel 530 240GB SSD x 2 - RAID 0
 
Plugged new psu in. Both GPUs powered up. Nothing on display. Changed DVI cable to other GPU. Nothing on display. Motherboard seems to have passed POST. Logged onto computer remotely. Everything fine, except nothing on display. Windows reports 'Standard Display Adaptor' in use.
 
I could not find a cable to put into the Z77 FTW cpu socket. There are three power sockets on the mainboard. One SIX PIN and two EIGHT PIN.
 
Now, when I previously used the other PSU, Corsair HX750, the hardwired EIGHT PIN cpu cable was redundant, as the Z77 FTW only requires a SIX PIN cpu power cable. I connected a supplied cable to the peripheral/hdd port and then to the motherboard, and the computer has worked fine for two years.
 
I tried every combination possible to power an EVGA Z77 FTW using an EVGA Supernova 1200W P2, and got nothing.
 
Switched PSUs back over and tried to run with one GPU, and nothing.
 
The board lights up. The onboard power buttons light up, but are completely unfunctional.
 
I have disassembled the older power supply and checked the internal fuse. Everything is fine. Cannot perform the 'paper clip psu test' though?
 
Starting to think my board, which is just out of warranty, is dead.
 
Can anyone guide me on the next steps to take?

Thanks for reply.
 
Can't POST anymore. Power button on board is green, when pressed nothing happens. No clicks, no fan activity at all. I can return the Supernova, and get a direct replacement from a popular online retailer, but I think my board is dead and out of warranty.
 
Can I test PSUs in anyway?

Your evga power supply comes with a tester. It should be in the box.

The paper clip test can be used on any psu. If you would like to speak with evga tech support directly you can call them anytime using the following contact numbers... https://www.evga.com/about/contactus/

Just received a replacement psu, installed straight into computer, and nothing still.
 
Tried changing bios selector switch, but the on board power buttons do nothing. The power button is coloured green and the motherboard won't power up at all.
 
I have tried removing ram sticks one by one and still get nothing. Does anybody have an idea what I could try next?

That board has 2 6 pin (another is way down the bottom on the left) and 2 8 pin power connectors on it, only the 8 pin is for the cpu, the other 2 give power to the pci express lanes.
I guess you`d have to run pci-e cables to them both, that is odd, read your manual, it should tell you. Or just call EVGA 
I would think they would all need a cable going to them.
As far as the 2nd cpu power connector that has the label over it being redundant, that is odd too, but you would know better then us, I can`t read what it says.
 
According to the pictures of it here anyway.

Read this, it talks about the other power connections.

UPDATE...
 
 
I have completely killed my Z77 FTW, after extensive testing it has died. I used cables from my previous PSU to power the sockets I thought needed power and killed the board.
 
Also, two Western Digital Black 2.0TB drives are dead, just clicking when spinning up, seen in BIOS but won't load in Windows at all. Tried Disk Management, DISKPART, MHDD, all the usual suspects and nothing. Thank God(!), I back up to my NAS as well.
 
Anyways, just thought I'd share my misfortune; hope I prevent anyone else doing the same. It's not like I forced the cables into the sockets! If they had different pinouts, why would they have compatible sockets/plugs?
 
Yeah, anyways, I have two GPUs now, EVGA GTX 780 Ti ACX SuperClocked, and EVGA GTX 780 Ti SuperClocked. Are these cards SLI compatible? My new motherboard - Intel DZ77GA-70K Extreme - supports SLI but the second card isn't shown in BIOS and I don't have the option to enable SLI through the nVidia Control Panel? The second card isn't shown in Device Manager, (Windows 8.1 x64 Pro), and isn't shown in GPU-Z.
 
This Intel board was purchased from the US, I couldn't find a good Socket H (1155) Z77 board anywhere here in the UK, retaining my i7 2700K and DDR3 RAM.
 
The cards are working as I have interchanged them, and within the second slot the GPU powers up and runs fine, just not seen in BIOS or Windows. I have upgraded the BIOS and using the latest nVidia drivers? Any thoughts or ideas to try?
 
I'll post this elsewhere if required as I understand that the message content is no longer relevant to the original thread topic.
 
 
Thanks in advance guys,
looking forward to owning another EVGA board in the future and not frying it!!!

I have a basic PSU tester, it can take the 2x12 for example and it has a bank of LEDs and if they are all green the PSU is ok
 
One damaged PSU only shows standby, which means the PSU is garbage, it does not power up any machine, even though when powered up the voltages are all active while it resets
 
 

The model I use has 2x12, SATA, PCI Express and Molex so it can check cables in addition to the PSU core capability
 
It has been very helpful in my shop, I also have a multimeter so I can check motherboards to see if power is being distributed etc
