honestly it looks like a legitimate factory test line from zotac, but id still be real careful about trusting these specs 100% yet. nvidia usually changes things last minute. if this thing is as power hungry as it looks, i would suggest getting your build ready for some serious heat. you might want to consider a few things before you get too hyped:

• make sure to upgrade to a high quality atx 3.0 power supply like the Corsair RM1200x Shift 80 PLUS Gold to avoid those nasty 12vhpwr cable issues.
• double check your case clearance bc that cooler looks absolutely massive... maybe look at the Lian Li O11 Dynamic EVO XL for enough room.
• be careful with your current cooling setup since the tdp is gonna be wild. id hate to see someone fry a new build over a bad cable connection. just take it slow and wait for the official tdp numbers tho. let me know if you want me to look over your current specs to see if theyll handle it.

It is fake.
