Zotac creates the first four-slot RTX 3090 Ti graphics card

Zotac has created the world’s largest RTX 3090 Ti model to date for the Chinese market, the RTX 3090 Ti PGF OC. Measuring a solid four PCIe slots thick, it’s matched only by the RTX 3070 Noctua Edition for girth, with the rest of Nvidia partner AIB’s RTX 30-series products (including other 3090 Tis) culminating at about 3.75 pitches.

At first glance, the PGF OC appears to be a sturdier and better looking version of the RTX 3090 Ti AMP Extreme Holo that we get in the US. It packs a three-fan cooler with two large fans on the sides, accompanied by a single smaller fan in the middle. The front fascia features a futuristic silver-on-grey finish, accented by purple LED lighting.

Despite the board’s massive size, it appears to have one of the shortest PCBs of any RTX 3090 Ti, rivaled by Nvidia’s Founders Edition SKU. It is “only” 30.9 cm long, compared to 31.3 cm for the Founders Edition (about 12.2 inches in both cases). It’s still a big card, sure, but not quite as big as some other models we’ve seen online which can reach 13 inches or more.

On the right rear of the card you can see a massive cutout in the backplate and PCB to let air through the card from the rear fan. This circular-shaped cutout alone takes up almost half the size of the card, accompanied by a purple LED logo on the back. The backplate itself is quite aggressive with more angular cutouts to the left to cool the rear components on the PCB itself.

Of course, we can’t forget how the card looks from the side, and at four slots thick, it’s a chunky card to look at. From the bottom of the board, you can clearly make out the large aluminum heatsink needed to cool the 3090 Ti’s 450W TDP. The fairing looms over the top of the board with an aggressive looking Zotac logo, complete with purple LED accents to the left and right of the logo.

According to the datasheet, the default power limit is “only” 450W, the same as the reference design. However, users can probably push that to 500W or more given the card’s huge cooler.

One thing we should point out – and sticking points for – is the dual-slot I/O support. Nvidia gets that part at least with its Founders Edition, which takes up three slots and includes a three-slot I/O bracket to help support the card’s weight. There’s no way to use both slots alongside that huge GPU, so we think Zotac (and other AIC partners) should beef up card support by moving to 3- or 4-slot supports. , depending on the case.

Pricing is currently unknown for this SKU, as it has not reached any in-market retailer that we know of. We expect this card to be very expensive, given its exceptional form factor and halo design aesthetic. Unfortunately for US and EU customers, we believe this card will be exclusive to Asian countries such as China, as Zotac only displays the PGF OC on its Chinese website.
