External Design Overview
The GALAX RTX 2080 EX graphics card 2x 100mm fans a large GPU fin array within it. You can see most of its PCB mounting from its side, where you can also observe heatsink mounting on the VRMs.
To complete it, there’s the plastic backplate. Visually, GALAX RTX 2080 EX has the requirements of a high card fulfilled here. The fan shroud is plastic while the backplate is metal.
Graphics Card Dimensions
The GALAX RTX 2080 EX is 11.61” x 5” and takes two-slot space. But because of its clean shroud design and sober paint job, the card makes the impression of being a standard size graphics card. The only part where it stands out is the paint job on the backplate. There are RGB LED lights on the fans, but it doesn’t bleed through the letterings on the side.
Power and NVLink Connector
The RTX 2080 Founders Edition has an official power draw rating of 225W, with a 650-watt power supply recommendation. For some reason, GALAX recommends a minimum requirement of 550-watt power supply. The GALAX RTX 2080 has the same additional PCIe power connector requirement as the Founders Edition- a single 6-pin and second 8-pin PCIe connection. There are no LED indicators over the connector’s area to indicate a proper/improper connection.
The RTX 2080 supports the use of NVIDIA RTX NVLink Bridge. The graphics card uses a PCIe 3.0 x16 bandwidth.
Rear I/O Options
The RTX 2080 Founders Edition has DisplayPort, HDMI and USB Type-C. While the GALAX RTX 2080 EX does not have a USB Type-C output, it has three DisplayPort 1.4 and a single HDMI 2.0b. The RTX 2080 supports up to four multi-monitor setup has supported 8K resolution at max.
Based on the clock speed and offerings, the GALAX RTX 2080 EX is placed somewhere between NVIDIA’S reference specification and RTX 2080 Founders Edition, with a custom cooler design.
GPU Cooler Design
There are six spring-loaded screws that you need to remove via the backplate area. The GPU cooler comes out easily. There are three connectors on the PCB going to the shroud.
While GALAX has a large heatsink array, the dismantling process is very clean. There are four nickel-plated composite heatpipes, with one of them cut short just after the heatbase, with a smaller one having a U shaped. One side of the pipe is having a contact with the copper base, with the other end kept in the middle. This way, GALAX is able to cover the entire heatbase from underneath to ensure the best possible heat draw from the GPU core.
Sleeve bearing fan?
Both the 100mm nine-blade fans are ECOTHERM sleeve bearing fans. These have no model numbers on it.
Internal PCB Observation
Contrary to the information on the website, the GALAX RTX 2080 EX has 7+2 Phase, with a clear indication of an empty phase area. This PCB isn’t different from RTX 2080 EX-OC, which is likely to be an 8+2 phase design. GALAX needs to make this connection on the website.
Sub Component Overview
NVIDIA has two SKU markings for the RTX 2080 8G- TU104-400-A1 which are not meant for factory OC- and the TU104-400A-A1 where AICs are allowed to set these chips with factory OC clock speeds.
In both cases, you can manually overclock them. This graphics card uses the A revision.
The card uses MPS1829 PWM controller and an array of MPS1852 DrMOS. The GDDR5 memory chips are made by Micron
