KFA2 has designed a current Turing card with the very simple GeForce RTX 2080 Ti OC, which could be considered a real Janus head. What makes the card very interesting for a very specific target group is its first BIOS, which I will discuss in more detail later. Since this card, however cynical it may sound, is one of the rather "cheap" GeForce RTX 2080 Ti, you will of course quickly reach thermal, acoustic and nervous limits with a rather small and light dual-slot cooler, as well as the two 8.5 cm fans.
Physics is a very solid science that cannot be tricked. But, and here one should read this article to the end, it also has advantages, which we can still highlight in another follow-up to a certain cooling method. But later on at the relevant places more. It is also important to note that I was in close contact with KFA2 after this review and that the manufacturer has now developed a new BIOS, which will also be taken over into mass production.
Important preliminary remarks on the test
The card tested today has a BIOS, the power target of which is 320 watts ex works and can be raised to the maximum power limit of 380 watts with suitable software. For air coolers like these, this interpretation is simply unsuitable, but highly interesting for all water cooling enthusiasts. Even if it's an original Nvidia PCB, this board can be flashed freely, which is definitely not possible with the Founders Edition of Nvidia right now!
KFA2 will soon deliver this card with another BIOS, whose values of 260 watts (out of the box) and a maximum of 300 watts are roughly what the Founders Edition offers. This air cooler tested here is again fully in the race, so that I can in any case offer a detailed post-test. I have already been able to test the new BIOS for a short time and it does exactly what the reduction was intended to do. So please stay tuned.
Unboxing and functionality
At 1150 grams, the card is quite light, which doesn't have to be negative yet, but already gives a glimpse of certain things. At 27.3 cm, it is also quite short and measures only 11.3 cm from the top edge of the slot panel to the top edge of the graphics card case. As a real dual slot card it is only 3.3 cm thick and the 0.5 cm for the backplate could be saved, because it could be removed quite easily. The card has a fan cover made of transparent ABS, which is illuminated by the RGB LED on a large area. You can like it or not.
Otherwise, the map is visually more of a grey mouse when you turn off the illumination. If you like it nicely colorful, you will be able to celebrate real RGB parties here.
KFA2 delivers the card with two external 8-pin ATX power supply connectors. This card has a maximum power limit (not to be confused with the Power Target) of 380 watts in the firmware, which would call into question the supply in that one of the supply rails would run above the specifications. I'll get to that later.

Test system and measurement methods
We have already described the new test system and the methodology in detail in the basic article "How We Test Graphics Cards, as of February 2017" and therefore refer to this detailed basis for simplicity. Description. So if you want to read everything again, you are welcome to do so. However, we have again improved CPU and cooling to largely exclude possible CPU bottlenecks for this fast card.
