Hi - I've just finished putting together the following new build:

i7 4770k
Asus Maximus Hero VI
16GB Corsair Vengence Silver
EVGA Supernova 1000W G2
2x GTX 770 SLI
Corsair Carbide 540 Case

Anyway I just wired everything up & plugged in for the first time, pressed the power button... And nothing

Are you sure you wired the front panel connectors correctly? check the standoffs, right amount? go through the cables again cpu, mb, gpu, fans, ect. plug and replug and reseat cards. and make sure you've switched the psu on. THen you can test the psu with the paper clip method to make sure it wasn't DOA.

Keep trying to reply from my phone but it seems to miss out the full message so trying again now from another device!

I did try checking the power switch connector & it is fitted as per the mobo manual. Even tried switching polarity just in case was plugged in round wrong way & still no luck

The mobo seems to be sat correctly & all mounting screws are in place so think that is fine.

Could be a dud PSU I guess - how do you go about the paper clip test?

Otherwise could be Haswell compatibility but sure it would at least power on as read non-Haswell psus just shut down when sleep states - booting up is far from asleep but then again I did read of another person not being able to boot until they got a Haswell ready supply!

The company also gave us a list of compatible power supplies, though it doesn't carry any surprises:

EVGA SuperNOVA NEX 1500 Classified (120-PG-1500-XR/VR)
EVGA SuperNOVA 1300 G2 (120-G2-1300-XR)
EVGA SuperNOVA 1000 G2 (120-G2-1000-XR)
EVGA SuperNOVA NEX750G Gold (120-PG-0750-GR)
EVGA SuperNOVA NEX750B Bronze (120-PB-0750-KR)
EVGA SuperNOVA NEX650G Gold (120-PG-0650-GR)

Thanks for the link Blackbird - that is the list I read before I ordered the Supernova 1000 G2 so EVGA claim its fine!

Been out today but just got back & taken another look & have just noticed that the PSU has two modules & cables for CPU power - each cable having 4+4 pin mobo connectors. I had originally just connected one cable from PSU & put the 4+4 on the other end in the mobo CPU ATX socket.

Do you think that perhaps it needs a both cables connected with only 4 of the pins from each cable?

I've just tried plugging the new PSU into my old rig & still nothing so I'm 99% sure it's DOA! Either that or the power cord it should have come with is some snazzy one that will only work with it because the other two kettle leads I've tried are not bringing any life to it!

Will give Scan a call in the morning & see if I can get a replacement sent out!

This is my 4th build & I've never had one that has gone smoothly - was really hoping this one would be it but alas - still where would the sense of achievement be if I didn't spend the best part of a week getting it up & running each time!

1 x 24 Pin ATX
2x 4+4 Pin EPS12V < No , you only need 1 of these plus the 24 pin to power the hero
6x 6+2 Pin PCI-E
10 x SATA
5 x Molex
1 x Floppy

Thanks - yes defo all plugged in correctly then so am pretty sure is DOA PSU after having tried it on my old machine too - surprised though as heard EVGA stuff usually v good but did read of a couple packing up after only month so maybe I just got unlucky!

Will hopefully get a replacement & fingers crossed the next one will work!

Looks good - will have to look into the warranty as to be honest the reason I went with the EVGA in the first place was for the 10 year warranty - but if it fails on delivery that's prob not worth a lot!

Just want a powerful well built PSU to support SLI & last the next couple of builds
