PCIe 4.0 ×16 Riser Cable 40 cm — 90° Angled, Right-Out / Left-In
type: Product
description: PCIe 4.0 ×16 · 40 cm · Passive · Shielded PCIe 4.0 ×16 Riser Cable — 40 cm, 90° Angled A full-bandwidth Gen4 ×16 riser with aluminium-foil-shielded differential pairs and a braided sleeve. Passive, so it needs no power and stays invisible to the system. This is the riser we use in our own multi-GPU builds. 4.0 Gen PCIe generation ×16 Full lane width 40 cm Cable length 90° Angled connectors Orientation Right-out / left-in — check this before you order This is the right-out / left-in version. The angled connectors are handed, so orientation is fixed and it is the one detail people get wrong. Work out which way the cable needs to leave the slot and enter the card in your chassis before ordering — if you need the mirrored version, ask us and we will supply that instead. Why the shielding matters Signal integrity at Gen4 speeds PCIe 4.0 runs at 16 GT/s per lane — roughly 32 GB/s per direction across sixteen lanes. At that rate a riser stops being a cable and becomes a transmission line: crosstalk and loss decide whether the link trains at Gen4 or quietly falls back. This one uses aluminium-foil-shielded differential pairs to keep the pairs isolated, which is what makes a run of this length viable at full Gen4 rather than Gen3. Practical note: 40 cm is a long run for a passive Gen4 riser. On most boards it trains at Gen4 without complaint. If yours is marginal — a heavily loaded platform, or a slot fed through a switch — you can pin the slot to Gen3 in BIOS and keep full stability with no other change. Tell us your board and GPU count and we will tell you what to expect.
