Nice one Kaap, hopefully this thread will fill up a little quicker than the 4080 owners thread. ![Smile :) :)](/styles/default/xenforo/vbSmilies/Normal/smile.gif)

Can anyone tell me why the Sapphire 7900XTX Nitro+ has 3x8pin power connectors?
Cool. Thanks.

Very.. I can't wait for the next batch to arrive.Overclocking headroom
After seeing the tuf results will be interesting what the nitro and red devil can do
Higher power demand. The TDP is higher. It’s also the case for the other aib xtx cards.Can anyone tell me why the Sapphire 7900XTX Nitro+ has 3x8pin power connectors?
Pretty much what I said...Higher power demand. The TDP is higher. It’s also the case for the other aib xtx cards.

As mentioned before, ASUS has overclocked and overvolted their card, to unlock higher performance. This means that power consumption is increased, by roughly 40 W, which is perfectly fine and makes sense, given that this is a 3x 8-pin design. This move does lower energy efficiency by 7% though, which is unfortunate, but still acceptable I'd say.
Overclocking worked really well on the ASUS TUF, better than on any other Navi 31 card that I've tested so far. What definitely helps here is the 3x 8-pin power inputs. While the AMD reference card very quickly ran into its power limit, even at the +15% power setting, the ASUS card has more headroom, which allows higher overclocks.
YepPretty much what I said...
Reading this makes me happy.The XTX cards overclock more with power limit on max and it seems more voltage means bigger overclock.
As such a 3x 8-pin card has a higher power limit, Nitro is biggest at 420W maxxed out whereas Red Devil is 380W. Reference I believe maxes out at 350W.
So in theory the Nitro have best chance of best overclocks if they win at silicon lottery too.
Not sure on Aorus but guessing it maxes out somewhere between 380-420W TDP.
So far the Sapphire Nitro is absolute best on power phase design and power limit. I’d also say they have best cooler as well as Sapphire noticed the junction hot spot temperature in reference was 110c plus and so addressed that with their cooler with a target of 86c and their target GPU temp 65c
The Nitro cooler is practically the same size as a 4090 it’s a beast and is the 7900 XTX I would personally buy.
Powercolour with Devil have designed their cars different to offer superior performance to MBA whilst only pulling 315W, so it’s very efficient design but can max out at 380W.
Actual 3D performance gained from overclocking is 0.9% / 1.2% / 6.8%
Actual 3D performance gained from overclocking is 9.9%.
why do you need a 4090 and a 7900 xtx? lolAnd here we go, snagged one at £999. For the owners list please @Kaapstad.
I believe we now equal the total number of 4080 owners on OcuK forums.
It cost half the price of my 4090 and it is literally half the size.
