The opposite of expensive does not always have to be cheap. In fact, it would also be inexpensive. This is exactly what KFA2 must have thought when the GeForce RTX 2070 EX was designed. Many things were taken over here from the larger KFA2 cards and also the cooler has a decent portiönchen hip bacon, so that nothing burns.
But they have also focused on hitting the price point (and probably the nerves of the buyers) as optimally as possible. The EIA of 499 euros is almost a battle announcement, because the cards of some competitors are up to 100 euros more expensive. Compromise? Well, it's not an A-chip. But we will see in a moment that this does not have to be a shortcoming if only the cooler is good enough to win Boost. And the 1-click-boost via software is also available.
Speaking of coolers… At 1073 grams, the card has been prescribed a light diet, but it is not a real ultra-light aviator. And that's a good thing, because somewhere the cooling surface has to come. The card is 28.5 cm long between the outer edge of the slot panel and the end of the radiator cover, measures 12 cm from the top edge of the slot panel to the top edge of the graphics card housing and is 4.7 cm thick. In addition, there is another 0.5 cm for the blackened backplate.
The cover is made of black, semi-gloss plastic with applied black light metal applications and of course there are RGB-lit rotor blades and the usual "GeForce RTX" lettering in full color. A bit of fun has to be easy and if you like to tap in the dark, you can also drag the roller blind down to night mode via software. The two 9.7 cm fans, each with 9 rotor blades, sit in a 10 cm opening.
The video outputs are the minimum assembly for the maximum controllable 4 output devices from Nvidia: once HDMI 2.0 meets 3x DisplayPort 1.4. But it's enough. KFA2 delivers the card with two external ATX power supply connectors (8-pin + 6-pin). But more the screenshot of GPU-Z gives us a first impression:
