The Zotac RTX 3090 AMP Extreme Holo ships in an eye-catching blue box, with Zotac's logo occupying most of the front. On the back we find two images of the card, as well as some key features and specifications.
A whole ton of documentation comes included, but more interesting is the metal support bracket, which is also RGB enabled. You can see it in action in the RGB showcase video at the bottom of this page. We do have to note however, a rubber piece is meant to come included to sit between the graphics card and the bracket itself, but no such piece was to be found with my sample.
Moving onto the card itself though, your eye is probably drawn first to the multi-coloured section that sits on the side of the card. This is actually one of the RGB zones on the card, as we can see below.
The shroud of the card is less special though, as it is made of grey plastic. It doesn't feel weak or flimsy, but compared to the likes of the ASUS TUF series that use all-aluminium shrouds, it neither looks nor feels as premium. We're hopeful about the cooling though, as Zotac is using three 100mm fans here, each sporting 11 fan blades.
In terms of the sheer size of the card, you will need a fairly roomy case to actually get this installed. That's because it measures 352.9mm x 144.7mm x 59.7mm… so don't expect to be installing this in your mini-ITX chassis! I believe this is the largest graphics card I have ever tested for KitGuru.
We usually expect to find a dual-BIOS switch on the side of the graphics card too. With the AMP Extreme Holo however, while it does indeed have dual-BIOS support, it is only possible to switch BIOS using Zotac's FireStorm software – there's no physical switch.
We can also note a metal backplate is used, but with a couple of RGB zones too – one either side of the GPU bracket.
The end of the card is home to a red cable header – Zotac uses this for its RGB, and an adapter to a 3-pin ARGB cable is included (as shown above) so you can directly attach the included support bracket, or any other ARGB accessory.
For power requirements, the AMP Extreme Holo makes use of three 8-pin power connectors, and remember the card has a 420W power target so three 8-pins is very necessary. Display outputs consist of 3x DisplayPort 1.4 and 1x HDMI 2.1.
Opening up the card now, we can take a look at the PCB. Zotac has employed a custom design here, with a whopping 16-phase VRM for the GPU and a 4-phase VRM for the memory. Zotac is using OnSemi's NCP252160 MOSFETs, with a trio of UPI uP9511R controllers – two controlling the GPU, and one for the memory.
You might have also noticed a large silver piece of the backside of the PCB, with the words ‘POWER BOOST' written on it. Zotac says this is a ‘control chip providing live electrical current regulation and instant electrical deviation responses. POWERBOOST reduces ripple noise, minimizes power fluctuations, and has a high temperature tolerance, resulting in a longer lasting longevity.'
Then for the cooler, we have a similarly impressive design. Zotac is using two fin-stacks, connected by no less than eight nickel-plated copper heatpipes. These contact with both the GPU and memory via a shared baseplate, while two other plates are used to contact the VRM MOSFETs.
RGB lighting is controlled within the FireStorm app. It's quite straightforward, with a range of different effects to choose from. The lighting is also very clean and well diffused, so if you like a graphics card with plenty of RGB, the AMP Extreme Holo does not disappoint.
