As ZOTAC launches its massively sized GeForce RTX 4090 PGF OC graphics card some PC owners are eyeing a bigger case for it. PGF, or premier gamer force, is ZOTAC’s flagship line and the GeForce RTX PGF OC is the new king that has been launched as a part of the company’s 16th anniversary. Featuring a 28 (24+4) phase VRM the custom PCB is capable of up to 525 W TDP, presumably the max for the 4090 GPU. The card has a single 12+4 12VHPWR connector.

As beautiful as the GeForce RTX 4090 PGF OC may be there is no denying the elephant in the room when it comes to its size. At 381×154×74mm it is possibly the largest air-cooled RTX 40 series graphics card to hit the market (although it is currently only on sale in Asia) so far. By comparison, ZOTAC’s previously released GeForce RTX 4090 AMP Extreme AIRO is
355.5mm x 149.6mm x 72.1mm. That card was listed as 3.5 slots wide, although reviewers stated it to be 4 slots, so this card is even larger and might be considered as 4-4.25 slots wide.

ITHome did its own testing with the card and was impressed with its cooling. The cooling solution combines 3x 110 mm fans, the middle spins in reverse for improved heat dissipation, with a vapor chamber. ZOTAC has included a 2,625 MHz OC mode via a BIOS switch or users could keep it at its stock 2,580 MHz setting. ITHome noted the card kept its VRAM stable at 76.6°C, with core temps ~67.8°C while drawing 450 W, during its testing but did not mention noise levels nor did it provide info for any manual overclocking, something this card could potentially excel at.

Other features include an ARGB 5V port for motherboard lighting control of its minimalistic RGB, a GPU stand/bracket, and 3x DP 1.4 plus a single HDMI 2.1 port. It is currently on sale at JD.com for 16,999 yuan (~$2,385) but those checking the specs there should be aware that they have been mixed with specs for the GeForce RTX 4090 AMP Extreme AIRO as well.

As a child of the 70’s I was part of the many who became enthralled by the video arcade invasion of the 1980’s. Saving money from various odd jobs I purchased my first computer from a friend of my dad, a used Atari 400, around 1982. Eventually it would end up being a lifelong passion of upgrading and modifying equipment that, of course, led into a career in IT support.
