So you think the problem is the GPU not the PSU or motherboard ?

nope

oh when my computer crashed I was playing WoW after that I couldn't start it without taking the GPU out. My friend lend me his old GPU ( radeon HD 6990) but I was lagging pretty hard. I tested Player Unknown Battleground and World of Warcraft. PUBG was lagging really hard and wow was playable but not the best compare to my 780 Ti.

Nothing Windows couldn't load at all with the GC plug in. it work just fine when I take the GC out

Picture of both PSU

after seeing the blue flag for a couple of second, my screen doesn't detect any output from the GC.

When I start my computer with my old PSU (semi modular I think) and the 780 Ti I can't pass the little blue windows flag without the screen turn off and doesn't detect any output. When I take the GC out and plug my screen on the mobo it work just fine.

Recently, I had a huge problem. I was gaming on WoW with some friends and in the middle of an instance, my computer crashed and was unable to boot windows. I had a problem similar a few month ago and it was my old HDD. So this time I was thinking my 4 years old SSD was the problem, but no it wasn't. I took my graphics card out and tried to boot the computer using the CPU Graphic card (I have an i7 4770k) and boom work like a charm (Oh yeah I changed my old SSD and reinstalled Windows). Now i'm thinking if it's my GTX 780 Ti the problem or something else. Without other computer to test my GC I bought a new PSU (EVGA Supernova 750G2) but when I plug everything on the new PSU my pump won't start and I get the code '99' on my motherboard. Now i'm confuse why my pump for my cpu won't start with the new PSU but work on the old one. Little recap : I don't know why my Graphics Card doesn't work anymore and don't know if my PSU or Motherborad can be the problem. I need your help !!! Parts: ROG Maximus Formula VII(Mobo), i74770k, Corsair HX 750(Old PSU), EVGA Supernova 750G2(New PSU). P.S Sorry for the poor english, it's not my first language.

Thanks ! I will definitely check it out.

Thanks a lot for your help guys ! With the Dell monitor and the Ti I will be set for a couple of time.

I'm Canadian so everything cost more.... I'm willing to pay 1800 CA$ up to 2000 max for both GPU and monitor. 24'' is enough for me. I have two 23'' 1080p monitor right now and i'm more than happy with them.

I want this resolution. I didn't know 2K was meaning something else

Do you have any recomendation for a decent/mid range 1440p monitor ?

Wow thanks a lot guys ! Tell me if i' wrong, but I heard it's better to play on a 2K/1440p monitor with a 1080 Ti. Is it true ?

Hi ! Later this month I want to upgrade my old GTX 680 for a GTX 1080 Ti (If I manage to grab one before they are out of stock ahah). But I don't know if my CPU will bottleneck my new card. I'm currently using : i7-4770K Stock 3.5GHz TurboBoost at 3.9 GHz,Corsair HX 750Watt PSU and a ROG Maximus Formula VII motherboard with 16 Go RAM. I'm also willing to buy a new 1440p monitor. I need your help before buying a decent 1440p monitor and the GTX 1080 Ti. P.S : Sorry for my bad english ^^
