First of all, I must mention again that the situation on the graphics card market is very bad, availability is annoying, as well as high prices are very unpleasant. The tested graphics card should be sold in some range of CZK 22-24,000 with VAT, but currently you will not find it in stores for less than CZK 30,000. I must also mention that the tested ASUS ROG STRIX GeForce RTX 3080 O10G GAMING belongs to the hi-end and in the field of various RTX 3080, so it can boast of preparation for extreme overclocking with liquid nitrogen, which is not something of interest to ordinary users.

Inside the merry box we find even some minimal accessories besides the card itself. ASUS comes with velcro straps that are suitable for tying cables, a small ruler made of printed circuit board, and somewhat surprisingly, there was a molex splitter for two Berg connectors in the box. However, I suspect that a previous reviewer has forgotten it here, I don’t see a word about this reduction on the ASUS product page, and it doesn’t make any sense, as Berg connectors could not be connected anywhere on the card.

In addition to the standard manual, there is also the ROG logo, a thank you card and a small game card with a picture of the card, which is something that ASUS attaches to newer cards.

The card itself is very massive. It takes up three slots without any problems (ASUS states 2.9 slots) and its length is 318 millimeters.

The outputs are relatively standard, there are three DisplayPorts 1.4a and two HDMI 2.1 outputs, but the GPU supports a maximum of four monitors.

The massive cooler is blown by three 100mm fans, with the middle one rotating in a different direction than the others for better airflow. The card fans can stop and spin them when the GPU reaches 55 ° C. However, if we use the Performance BIOS, the fans will also spin in the idle.

The BIOS switch has two modes, Q Mode and P Mode. Both have surprisingly the same power limit for the entire card, a high 370 Watts. They differ primarily in fan speed control, P Mode is more aggressive and generally more suitable for overclocking. The card is also ready for clocking with liquid nitrogen, which is again something for enthusiasts.

The back plate is made of metal and dissipates heat from the PCB, and here we find a cutout for air to flow through, as some Radeons Fury or Vega had. There are also two four-pin connectors to this exhaust, to which we can connect fans, which will then be controlled by the graphics card itself.

The card also offers RGB backlighting on the side and through the fans, it looks quite good in my opinion.

I decided to test the card in Q Mode, because this mode is factory set and sufficient for 98% of users. If you plan to overclock manually, be sure to switch to P Mode. However, in Q Mode, the card is very quiet, the graphics core boosts around 2GHz and the fans only spin at some 1400 RPM! In addition, both BIOSes have the same power limit, primarily different fan behavior. I did not try overclocking for time and power reasons, I was worried that my test Seasonic SSP-750RT might not be enough, as in some situations the whole set took over 550 Watts without overclocking, but this is not the rule.

Now for the test set, I used more or less such a “regular” hi-end computer based on the AMD AM4 platform with the AMD X570 chipset. The processor is not overclocked in any way, it is cooled by a cheap CoolerMaster MasterLiquid ML240L, the memories are set to 3600 MT / s with timing CL14-14-14-32 1T.

The assembly consists of the following components:

  • AMD Ryzen 9 5900X
  • G.Skill TridentZ NEO 2x8GB DDR4-3800 CL16 – nastaveno na 3600 MT/s CL14
  • Gigabyte X570 AORUS PRO
  • ADATA SX8200 Pro 2TB PCIe NVMe SSD x4 Gen3
  • Seasonic SSP-750RT 80PLUS Gold 750W zdroj
  • Fractal Design Focus G cabinet
  • Windows 10 Pro v2004

The fans in the cabinet are then set to automatic with a Normal preset and are controlled according to the CPU temperature. I had about 24 ° C in the test room. The test monitor was the Samsung U32H850, which has a native 3840×2160 resolution and supports FreeSync, and with NVIDIA cards it also works as a G-Sync Compatible.
