Add four RS-232, RS-422, or RS-485-capable DB9 Serial Ports to a desktop computer via PCIe x1 Expansion CardAdd serial communication support to a desktop computer or Small Form Factor (SFF) system, using this 4-Port Serial PCI Express Card. The four DB9 ports can be independently configured to support RS-232, RS-422, and 2/4-wire RS-485 standards, for communication with compliant serial peripheral devices.Per-Port Serial ConfigurationThis PCIe Serial Card is equipped with on-board DIP switches, enabling each DB9 serial port to operate in RS-232, RS-422, and/or RS-485 mode(s). The card features LED indicators per port, providing real-time monitoring of port activity.Configurable External SATA PowerThe PCI Express Serial Adapter Card features three power modes that are configurable via on-board jumpers, including 12V (1.5A per port), 5V (1.5A per port), or no power (RI), over pin 9.Legacy ConnectivityThis serial card enables the continued use of legacy serial devices, preventing down time and avoiding costly upgrades. The 4-Port PCIe Serial Card is an ideal system upgrade for a wide range of applications (e.g., point-of-sale terminals, PLCs, factory control and automation, scientific sensors, medical equipment, scanners, and oscilloscopes)The StarTech.com Advantage

2x Fans. 2x Fun.Delivering the latest AMD RDNA™ 3 architecture experience in its purest form, the ASUS Dual Radeon™ RX 7800 XT OC Edition melds performance and simplicity like no other. Leveraging advanced cooling technologies derived from flagship graphics cards, the Dual opts for substance over style, the perfect choice for a well-balanced build. Buckle up and engage cutting-edge gaming prowess.Axial-tech Fan DesignBetter, faster, strongerTwo tried-and-true Axial-tech fans feature a smaller hub that facilitates longer blades and a barrier ring to increase downward air pressure.Auto-Extreme TechnologyPrecision automated manufacturingAuto-Extreme Technology is an automated manufacturing process that sets new standards in the industry by allowing all soldering to be completed in a single pass. This reduces thermal strain on components and avoids the use of harsh cleaning chemicals, resulting in less environmental impact, lower manufacturing power consumption, and a more reliable product overall.GPU TWEAK IIIMonitor, tweak, and tuneThe ASUS GPU Tweak III utility takes graphics card tuning to the next level. It allows you to tweak critical parameters including GPU core clocks, memory frequency, and voltage settings, with the option to monitor everything in real-time through a customizable on-screen display. Advanced fan control is also included along with many more features to help you get the most out of your graphics card.Pair with a PSUUse our wattage calculator to estimate how much power you’ll need to fuel your rig, and then pick a compatible ROG Thor, ROG Loki or ROG Strix AURA power supply for ultimate performance.
