Cooler Master Riser Cable PCIe 4.0 x16 300mm V2 - White / Ultra Durable PCB / Gold-Plated Pin Connections / PCIe 4.0 Compatible / MCA-U002R-WPCI40-300 / MCA-U002R-WPCI40-300

The Cooler Master Riser Cable PCIe 4.0 x16 300mm V2 in white, part number MCA-U002R-WPCI40-300, repositions your graphics card inside the case instead of locking it to the motherboard slot. At 300mm it has the reach for larger builds, and an ultra-durable PCB with gold-plated pin connections carries the signal. It is fully PCIe 4.0 compatible for high-speed transfer from modern components.

Cooler Master's PCIe 4.0 Riser Cables V2 come in both black and white, so the cable matches the rest of the build rather than fighting it. This 300mm version is the white finish, which suits light-themed cases where a black cable would read as a dark line across an otherwise clean interior once the side panel goes on.

The Gen 4.0 riser cable carries double the bandwidth of PCIe 3.0, with a maximum transfer rate exceeding 64Gb/s bi-directional and full support for the 16GT/s bit rate of PCIe 4.0 devices. It stays backward compatible, so an older PCIe 3.0 graphics card still works on the same cable without a change of hardware.

Inside the sleeve sit EMI shielded 30 AWG silver-plated wires, chosen to hold signal delay to a minimum and keep operation free of electromagnetic interference. A riser cable runs close to power cables, fans and a graphics card under load, so the shielding is what stops that environment from degrading the link.

The PCI pins are gold plated for durability and carry a retention force rating of 400g per contact pair. That retention figure is the number that matters on a riser, because the connector has to hold a heavy graphics card steady through transport, repeated reseating and years of thermal cycling without the contact loosening.

The connector casing is UV-resistant ABS, redesigned on the V2 into a more compact form to make installation easier. A smaller shell gives you more room to work in a crowded case, which matters when the riser has to seat between a graphics card backplate and a front radiator with very little clearance.

New TPE cable sleeves on the V2 add flexibility and durability for the tightest routing scenarios. A 300mm run usually has to bend behind the motherboard tray or around a cooler before it reaches the card, and a sleeve that flexes rather than resists is what lets you set that path without stressing the ribbon.

The multi-layer coated PCB is built for performance under high thermal loads, repeated cable flex and moisture. Combined with heavy-duty shielding that keeps electromagnetic interference from degrading signal quality, it is what makes the 300mm V2 dependable for a long-term install rather than only on the bench the day it goes in.
