Colorful has introduced a new generation of iGame Ultra Z graphics cards, with the most attention-grabbing model being the Colorful RTX 5070 Ti iGame Ultra Z. The manufacturer brings a series that combines the modern BTF 2.0 power system with classic connectors, so that the cards work in both traditional enclosures and new “cable-free” platforms. The decision to keep both power supply types makes the Ultra Z series flexible and ready for both older and newer motherboards.
Although Colorful also introduced the RTX 5060 Ultra Z, the focus of the series is on the Colorful RTX 5070 Ti iGame Ultra Z, which targets users demanding higher performance and better cooling. The novelty comes with a modified PCB, Ultra Z technical design, and a solution that allows for a gradual transition to the BTF platform without having to change the entire build.
Technical introduction of the models, highlighting the Colorful RTX 5070 Ti iGame Ultra Z
Both models use the Blackwell architecture, but it is the Colorful RTX 5070 Ti iGame Ultra Z that is presented as the more powerful option for gamers and creators alike. Colorful confirms that the Ultra Z series supports the BTF 2.0 standard while retaining the traditional power connectors, so users can install the cards in any type of enclosure.
BTF 2.0 is a new wiring standard that moves the graphics card’s power connectors to the underside of the PCB. This makes cables disappear from the inside of the case and the entire assembly looks cleaner, clearer and has better airflow. BTF 2.0 requires a compatible motherboard, but the card remains functional even with classic connectors if the manufacturer retains them.
The exact memory parameters and clock speeds have not yet been disclosed by the manufacturer, so the confirmed data are mainly about the power layout, architecture and designation of individual models. The RTX 5060 Ultra Z is aimed at the mid-range, while the Colorful RTX 5070 Ti iGame Ultra Z represents the higher-end with significantly more robust processing and sophisticated cooling.
Some of the parameters of the models below have not yet been officially confirmed by the manufacturer, so this is a combination of confirmed data and realistic estimates according to reliable sources.

IGame Ultra Z series design and cooling
The Ultra Z series utilizes an upgraded heatsink with dense finning and a trio of fans, which greatly helps with the higher power demands of the RTX 50-series. In particular, the Colorful RTX 5070 Ti iGame Ultra Z uses both a more robust heatsink and a larger base to better dissipate heat from the GPU and VRAM. Colorful has gone for a simpler and more technical visual without aggressive decoration, which lends itself to both professional and gaming builds. The Ultra Z design looks clean, stable and functional.
Conclusion
TheColorful RTX 5070 Ti iGame Ultra Z is the star of the new Ultra Z series and delivers a solution that combines modern design, flexible power supply and sophisticated cooling. Although the manufacturer hasn’t released detailed memory and clock specifications yet, confirmed information suggests that this is a card suitable for more demanding users who want stable performance and BTF platform preparation.
The RTX 5060 Ultra Z completes the mid-range offering, but it is the Colorful RTX 5070 Ti iGame Ultra Z that represents the most attractive option for those who want to make the transition to the RTX 50-series without compromising on compatibility. Thus, the Ultra Z series delivers solutions that adapt to both legacy and modern builds and allow for easy upgrades without unnecessary restrictions.
