EVGA 1080ti's not posting

[cancuniproject]

So, I bought 2 1080ti's off eBay and they arrived today. Problem is that they aren't working, neither of them. When I try to boot, the vga led lights up red on my mobo for about 15 seconds, and then the boot device led turns on, and the bus led turns off, as Well as getting an A2 code on my Asus mobo. Whilst this is happening, I get a black display on my monitor, as is there's a signal, but it's only showing black. Please help guys, anything is appriciated!

Also, for some reason, only one of the cards lights light up if that is of any importance

Sounds like you got sold two non-working 1080 Ti's. What brand are they? You could possibly RMA them with the manufacturer under second owner warranty. Or, you could return them on eBay.

They're EVGA sc 2's but I simply can't believe that they aren't working, as they look perfect and came with all the accessories and packaging etc. Also, the eBay seller stated the reason for selling was cuz of the 2080tis and EVGA cards have 3 year warranties so I don't see why that wouldn't be true

I've got enough of a headache trying to troubleshoot this, and going through an RMA won't really help it, so I'm desperately searching for a solution, if there is one. But I do appreciate the help

EVGA will RMA the cards.

Do you have everything connected properly? What power supply? What other parts?

 

[SgtScream]

Have you tried installing them individually?

They could have been mining, an RMA is by far the simplest solution. The fact that they look nice and clean is nothing really.

However, what PSU are you running and are you plugging power in properly to the GPU?
Have you done a bios reset (have seen some suggestions of this working elsewhere).

I've done extensive benching. When i put in my 980 it all works fine, when i'm using the 1080ti's (i've tried them individually) the thing actually still boots sometimes somehow. i can tell because the lights on my keyboard change to my software settings, so it must've posted. So there is just no display? I don't know the solution to this though

I've got a cx750m so there should be sufficient power draw.

Yeah, they could have, but when i was dealing with him it genuinely sounded like it wasn't a mining card. And yeah, you're probably right, and them having all the peripherals might (or might not i'm unsure) hint towards them being mining cards, as they're more likely to keep all the accessories for resell purposes.

Yes, i am plugging in the plugs correctly
PSU: corsair cx750m

Going through an RMA might be tricky as i don't have the original receipt even though i asked for it (and i did again just now) but i'm unsure if that's even necessary

I'll be contacting them, and if i can't go through with an rma there's always ebay money back guarantee
