Ximhun Cat 8 Ethernet Cable 40FT

Bottom line: The Ximhun Cat 8 Ethernet Cable 40FT ($15.19 on Amazon as of 2026-10-06): 40Gbps at 2000MHz rating, well ahead of Cat6 gigabit ceilings; main trade-off: cat 8's 40Gbps ceiling is wasted on typical gigabit home routers.

  • ✓ Flat profile slips under carpet, doors, and baseboards without coiling

Manufacturer description

The flat design slides under carpets, along baseboards, and through door gaps without the coiling and tangling that plagues round cable, and the 30 wall studs included with the 40FT length let you tack the run exactly where you want it. Ximhun rates the jacket for direct sunlight, extreme cold, humidity, and heat, so the same cable works for an indoor desk run or an outdoor pull between buildings. The cotton-braided wrap is rated for at least 10,000 bends, which matters if you re-route your setup often. Backward compatibility with Cat7, Cat6, and Cat5 equipment means it drops straight into…

SpecPicks Verdict

SpecPicks scored Ximhun Cat 8 Ethernet Cable 40FT using a rating × review-volume × price-fit model applied to published specs and reviews across the networking category. Ximhun's networking lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.

Common buyer scenarios for networking of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase.

Frequently Asked Questions

Will this Cat 8 cable actually make my internet faster?

Only if your equipment is the bottleneck. The cable is rated 40Gbps at 2000MHz, but your speed is capped by your router port and ISP plan. It removes the cable as a limit, not your service tier.

Can I run this Ximhun cable outside?

Ximhun states the jacket withstands direct sunlight, extreme cold, humidity, and hot weather and still works effectively. For buried or conduit runs, check the product listing for the specific installation rating.

Does it work with my older Cat6 router and switch?

Yes. Ximhun lists compatibility with Cat7, Cat6, and Cat5 equipment, and the RJ45 connectors fit routers, modems, switches, PCs, and laptops. It negotiates down to whatever your gear supports.

Will this work with a PS4 or Xbox?

Yes. The listing names PS4, PS3, and Xbox consoles among supported devices, alongside PCs and laptops, so it plugs straight into a console's Ethernet port.

Do I get anything to mount the cable along a wall?

Yes. At the 40FT length, Ximhun includes 30 wall studs; the 20ft and 25ft versions include 15. The flat profile is designed to sit flush when tacked along a baseboard.
