The Zotac RTX 3090 Ti Amp Extreme Holo ships in an attractive blue box, with the Zotac logo taking pride of place in the middle.
On the back, Zotac highlights a handful of key features of the card.
Inside, we get a bunch of leaflets and documentation, as well as a couple of stickers. More interesting is the GPU support bracket, which is RGB-equipped, and a power adaptor is also included for the PCIe Gen5 16-pin header that is used on the card.
Taking a look at the card itself, as we mentioned on the first page, the design is very similar to the RTX 3090 Amp Extreme Holo. Zotac is using a dark grey plastic shroud, but your eye has probably been drawn by the holographic plastic section on the top of the card – this is one of the card's RGB zones, as shown below.
As part of the HoloBlack cooler design, we can also note three 100mm fans. Interestingly, both of the outer fans have solid, matte fan blades whereas the central fan has glossy, translucent fan blades.
As with any RTX 3090 Ti, the Amp Extreme Holo is absolutely massive, measuring 355.9mm x 149.7mm x 63.9mm. That makes it a proper triple-slot card, and it is very long too, so definitely double-check that this will fit in your case. You may want to use that included support bracket too, as the card weighs 2.08KG on my scales.
Here we get another good look at the holographic section on the card, while we can also note the metal backplate that is used. This features two RGB lighting sections – the Zotac logo on the left side, as well as the angular LED strips over towards the end of the card.
For power, we find a single PCIe Gen5 16-pin connector. Display outputs consist of 3x DisplayPort 1.4 and 1x HDMI 2.1.
Opening up the card to look at the PCB, the first thing to note is the unusual diamond-shaped cut-out in the PCB itself – there's just a big hole to the right of the GPU and memory chips. In theory this would allow for airflow to pass straight through the heatsink and PCB, but Zotac has mystifyingly blocked this cut-out with the card's backplate, allowing on a very small amount of airflow out thanks to a few tiny cut-outs in the metal.
Still, we can note a whopping 18-phase VRM for the GPU and a 3-phase VRM for the memory, with Monolithic Power Systems MP86597 MOSFETs used, each rated for 70A. A MPS MP2981 controller is used. We can also note 12x 2GB GDDR6X memory modules from Micron, carrying the D8BZC model code.
As for the heatsink, not only is it a beast of a unit, with eight heatpipes used, but it also boasts a vapour chamber – something we very rarely see from AIB card designs. The GPU and memory sit directly above said chamber, while the VRM contacts with a baseplate to either side.
Here we get a look at the underside of the metal backplate – only three small thermal pads are used, one of which sits over the MP2981 controller.

Lastly, in the video above you can get a look at the RGB lighting, which is controlled via Zotac's FireStorm software. It looks clean, shines through very well and is also nice and bright, so for RGB lovers I can have no complaints.
