4x8 Pin to 12VHPWR 90° Angled Extension Cable 600W PCIe 5.0 16AWG, Type B (4-Pin on Top) for RTX 5090/5080/4090/4080/4070 Ti/3090 Ti, 5.9in Short Sleeved Adapter, 4 Connectors Required

1. COMPLETE 4X8PIN INPUT FULL 600W FOR RTX 5090 & 4090 This is a 4x8pin to 12VHPWR adapter featuring four (4) individual 8pin PCIe female connectors, distributing the power load across four separate PSU ports for maximum safety and performance. The RTX 5090 officially requires 4 x 8pin PCIe cables our 4x8pin design meets this requirement. Each of the four 8pin inputs must be connected. This is not a 3x8pin cable.
2. TYPE B CONFIGURATION 4PIN ON TOP Features Type B configuration with 4pin sense wires positioned on the top side of the connector (closer to the GPU backplate). This design is optimized for graphics cards with components or capacitors directly below the power connector. Type B is for GPUs where the area BELOW the power connector has limited clearance verify your GPUs layout before ordering.
3. 12V2x6 H++ CONNECTOR PCIe 5.1 & ATX 3.1 COMPLIANT Equipped with the latest 12V2x6 H++ connector (ATX 3.1 / PCIe 5.1), featuring shorter sense pins that ensure full insertion before power is delivered. Supports up to 675W peak power, providing a generous safety margin for RTX 5090 (575W TDP). Fully compatible with both 12VHPWR and 12V2x6 GPU ports.
4. 90° ANGLED CONNECTOR ONLY 20MM SIDE PANEL CLEARANCE Factorymolded 90° angled connector eliminates the need to bend cables near the GPU port the #1 cause of connector failure. Requires only 20mm of clearance from the side panel, allowing wide GPUs to fit in compact cases. Unlike recalled removable adapters (CableMod), this is a full cable, not a removable adapter safer singlepiece design.
5. SHORT 5.9INCH (15CM) LENGTH PERFECT FOR ITX & SFF BUILDS Total length of just 15cm (5.9 inches) eliminates cable clutter in ITX and small form factor builds. The short length naturally helps maintain the required straight approach to the GPU connector (no bending within 35mm), reducing the risk of connector failure.
6. 16AWG PREMIUM CONSTRUCTION HIGH THERMAL ENDURANCE Built with highquality 16AWG tinned copper wire, capable of carrying up to 55A of current with 105°C temperature rating. Premium 12V2x6 connector features highcurrent terminals rated for reliable power delivery. 12 dedicated wires no soldering, no bridging, no sharing.
7. EXTENSION CABLE WORKS WITH ALL PSU BRANDS This is an extension cable connects to your power supplys existing 8pin PCIe male cables, NOT directly to the PSUs modular ports. Works with ALL PSU brands (Corsair, EVGA, Seasonic, ASUS, Thermaltake, Cooler Master, etc.) as long as your PSU has four (4) available 8pin PCIe outputs.

NVIDIAs flagship RTX 5090 requires up to 575W of power. To deliver this safely without a native 12V2x6 power supply, the official specification calls for four (4) individual 8pin PCIe cables. Our 4x8Pin to 12VHPWR 90° Angled Extension Cable (Type B) meets this requirement exactly distributing the full 600W load across four separate PSU ports for maximum safety and performance.

Why 4x8Pin Instead of 3x8Pin?

Feature 3x8Pin Cable Our 4x8Pin Cable

Total Power Capacity 450W 600W

RTX 5090 Support Limited to 450W (~5% performance loss) Full 600W zero performance loss

RTX 4090 Support Limited Full 600W

RTX 5080 Support 360W sufficient but no headroom Full 600W generous headroom

Safety Margin for 5090I nsufficient (450W < 575W TDP) Ample (600W capacity)

RTX 5090 can technically run on 3x8pin cables at reduced power, but youll sacrifice performance. For uncompromised performance and safety, 4x8pin is the proper specification.

Type B (4Pin on Top) positions the 4 sense pins on the top side of the connector (closer to the GPU backplate)-7. This configuration is optimized for GPUs where the area below the power connector has components or capacitors that could interfere with a Type A (4Pin on Bottom) adapter-.

Type B is recommended for:

1. Graphics cards with components or capacitors directly below the power connector
2. GPUs where the area below the power connector has limited clearance
3. Ensuring full insertion without obstruction from PCB components

Check your GPUs power connector area before ordering. If the area below the connector has components, choose Type B. If the area above has components (like a thick backplate), choose Type A.

This cable features the latest 12V2x6 H++ connector from the ATX 3.1 / PCIe 5.1 specification. The H++ marking indicates terminals rated for 9.2A per pin or higher, supporting up to 675W peak power. The shorter sense pins ensure full ins
