We have received the KFA2 RTX 2070 EX 1-Click OC graphics card for your review. This graphics card is based on NVIDIA Turing silicon with support for Ray Tracing technology. KFA2 has opted for a fairly simple design in terms of heatsink based on two 100mm fans, both with RGB. This graphics card is factory overclocked by KFA2.
NVIDIA's Turing architecture is characterized by adding hardware support for Ray Tracing. Real-time ray tracing is a technology that still needs a lot of development, but it does point out ways. Currently this technology has a great impact on graphics performance and that is not yet fully implemented.

Presentation KFA2 RTX 2070 EX 1-Click OC
KFA2 on the front usually opts for a distinctive and striking design. Most manufacturers opt for a photo of their graphics, but this brand bets on the image of an anonymous gamer. It shows a small schematic image of the graph in white. The back has some data regarding this graphics card.
Inside, as logic dictates, we will find the well-protected graphics card. A graphics card is an expensive and delicate component and this (like the vast majority) is encased in a slot die-cut for it of flexible plastic that absorbs shock. We will also find the graphic, a quick installation manual (unnecessary) and two power adapters.
This RTX 2070 is enclosed in an antistatic plastic bag that protects it. An additional protection system for delicate electronic components, as is the case.
Features KFA2 RTX 2070 EX 1-Click OC
We clearly see how KFA2 has opted for a simple but efficient solution for this RTX 2070 EX. The aluminum fin block is covered by a trim casing with the fairly simple fans. It is neither the best heatsink nor the most beautiful, but this heatsink is a basic model, it is not one of the best the company offers.
The KFA2 graphic has dimensions of 295x143x51mm and occupies 2.5 PCI slots. We see how the heatsink of the graphics has been growing and we have already exceeded the 'limit' that existed a while ago of 2 PCI slots. On the one hand it is good, it improves dissipation, but on the other hand, we have limitations when installing other elements.
Regarding the working frequencies, KFA's bet for this RTX 2070 EX is quite curious. The company has opted to make it operate at 1 410MHz and in Boost mode it reaches 1 620MHz. These two frequencies are the reference ones, but, this graph is marked with factory overclocking. The 1-Click OC function has been added, a software function that allows the Boost frequency to rise to 1MHz.
Regarding the power supply of this graph, it should be noted that it has a 6-pin PCIe connector and an 8-pin one. This leaves us with that this graph has a TDP of 185W, so for this graph a 650W power supply is recommended
KFA2 RTX 2070 EX 1-Click OC Connectivity
NVIDIA Turing silicones only support PCIe 3.0 interface, so this graphic makes use of this interface. We see that it has the typical PCIe 3.0 x16 connector for graphics. This graphics does not have multi-GPU support, as NVIDIA has reserved this technology for the RTX 2080 and higher models.
We move on to the connectivity of this graphics card. The cut in connectivity that this model has suffered is strikingly striking. Only one HDMI 2.0b and two DisplayPort 1.4a ports have been left. The USB Type-C Virtual Link, designed for VR glasses, has disappeared. Note that this graphics natively supports HDCP 2.2 and lossless DSC in resolutions 8K @ 30Hz and 8K @ 60Hz.
KFA2 RTX 2070 EX 1-Click OC Heatsink
KFA2 has chosen to install a fairly simple heatsink to this RTX 2070 EX, without anything particularly striking. It is clear that the company's low-end heatsink, betting on a solution that offers good performance and an adjusted price.
We have a system of two aluminum blocks crossed by heatpipes and reinforced by two 100mm fans. These fans make use of Silent Extreme technology, which prevents the fans from not working if there is no load. It offers us an air flow of up to 70.1 CFM and a static pressure of 4.31mm.
It is not by far one of the heaviest models, but to avoid problems and also as a trim, a backplate has been installed. This backplate, in addition to preventing the PCB from bending, supports a little cooling. We see that the backplate of this RTX 2070 EX is made of aluminum with a black finish and some elements in white. This backplate has perforations so that the air moves by convection, helping in cooling.
On the two aluminum blocks of the heatsink, they are crossed by four copper heatpipes. These have the mission of distributing the heat through the different aluminum fins. Large thermal pads have been installed on the VRMs and on the GDDR6 memory modules, which is appreciated. We have already seen what happens when other manufacturers racan on this element that has a very low cost.
KFA2 RTX 2070 EX 1-Click OC PCB
We have already advanced something about the PCB in the previous point. The thermal pads hide the eight GDDR6 memory chips and the high-quality MOSFET-based 6 + 2-phase VRM phases. As we can see, the thermal pads are of high quality and completely touch the components, even there is no thermal pad. This is an extremely inexpensive item and not worth skimping on as you could end up damaging components.
The power connectors already suggested that it was not designed to withstand a lot of overclocking and the VRM phases confirm this. Yes it supports overclocking, but without passing us. In addition to the factory one, we could scratch a little more frequently, but we are not going to go crazy either. We can do it easily with the KFA2 Xtreme Tuner tool.

Conclusion
The solution that KFA2 proposes to us with this RTX 2070 EX 1-Click OC is clear: good performance at a reasonable price. It has RGB, because it seems like it's an intrinsic necessity, although they could have saved it. The heatsink is ugly, so why deny it, but it seeks to offer good performance, leaving aesthetics in the background.
It has some overclocking, not automatic, but selectable. This can be good and not at the same time. We can decide when we want to add an extra performance and extend the life of the silicon. The bad part is that we have to install software for a meager 45MHz to get 1% more performance, hopefully.
If you are interested in an RTX 2070 to play with Ray Tracing and want to save a few euros, this may be a good option. The dissipation system, despite not being the most beautiful, is efficient, which is important.
What we liked the least is the brutal cut in connectivity that they have made to the graphics. It is true that not all video connectors are used and USB Type-C does not make sense, but they have been removed and that has not ended up looking correct.
