PCI-E Extender Thermaltake TT Premium 300mm with 90 Degree Adapter

Thermaltake TT Premium PCI-E 4.0 Extender – 300mm with 90-degree adapter is a flexible PCI‑E riser cable designed to relocate a PCI‑E x16 graphics card inside compact or custom PC builds. The 300mm ribbon-style cable supports high-speed PCI‑E signaling while allowing vertical GPU mounting or alternate placement to improve space management and airflow in the chassis.

Advantages

The extender provides ultra-high-speed transmission capable of supporting PCI‑E 4.0 bandwidth requirements and is built with a foldable, ribbonized flat cable that permits tight bends for space-saving layouts. Conductive-polymer EMI shielding on each flat cable reduces electromagnetic interference and helps preserve signal integrity. An integrated cable protector increases durability where the cable is bent or twisted, and the included 90-degree adapter enables vertical GPU installation without modifying the motherboard layout.

Suitable for

• Small form factor or custom PC builds where GPU placement needs to be relocated
• Vertical GPU mounting to showcase a graphics card
• Systems requiring improved internal airflow or cleaner cable routing
• Graphic design, gaming, and multimedia setups that demand stable PCI‑E connections

Key specifications

• Cable length: 0.3 m (300 mm)
• Connector 1: PCI‑E x16 (Gen 3.0)
• Connector 2: PCI‑E x16 (Gen 3.0)
• Supported bandwidth: up to PCI‑E 4.0 speeds (high-speed graphic data transmission)
• Weight: 0.11 kg
• Colour: Black
• Includes: 90-degree adapter for vertical GPU mounting

How to use

Install the extender by connecting one PCI‑E x16 connector to the motherboard slot and the other to the graphics card PCI‑E x16 interface. Use the 90‑degree adapter when a vertical GPU orientation is required. Route and fold the ribbon cable carefully to fit inside the chassis while avoiding extremely sharp bends; the ribbonized design permits tight radii but avoid kinks that could stress the conductors. Ensure both connectors are fully seated and secured before powering on the system.

Recommendations

For optimal performance, pair the extender with compatible PCI‑E x16 devices and confirm motherboard support for riser cables. Arrange the cable to maintain airflow around the GPU and avoid placing heavy objects on the ribbon cable or at connection points to reduce mechanical stress and preserve signal integrity.
