ZOTAC NEBULAE OC HA RTX 5050 8GB graphics card

Product identity

The ZOTAC NEBULAE OC HA RTX 5050 8GB is a compact graphics card built around the NVIDIA RTX 5050 GPU with 2560 CUDA cores and 8GB of GDDR6 memory on a 128-bit bus. It targets builders who want a modern PCI Express 5.0 x8 card for 1080p and 1440p gaming in a 2.5-slot form factor. The factory core clock reaches 2602 MHz while the memory runs at 20 Gbps. A dual-fan cooler with two heat pipes handles the 130W power draw from a single 8-pin connector.

Upgrade path

This card replaces older 8GB models that use PCI Express 4.0 and HDMI 2.0 outputs. The jump is worthwhile when your monitor supports DisplayPort 2.1b UHBR20 for 4K at 480Hz or 8K at 165Hz with DSC, or when you need HDMI 2.1b for 4K 120Hz HDR and variable refresh rate. The 600W PSU recommendation fits many existing mid-range builds without a power-supply change. Windows 10 64-bit 1809 or Windows 11 is required.

Sustained behaviour

Under continuous load the dual heat-pipe, dual-fan cooler keeps the GPU at its 2602 MHz boost without throttling, thanks to the modest 130W thermal envelope. The 128-bit memory subsystem delivers steady 20 Gbps bandwidth for extended sessions. Outputs remain stable across all four display connectors — three DisplayPort 2.1b and one HDMI 2.1b — supporting quad-display productivity or surround gaming. The 2.5-slot width and 238mm length fit most ATX cases while leaving room for airflow.
