Who it fits

Key specs explained for this cable

Length: 19.68in (500mm)

This length provides extra slack between your power supply and motherboard. You can route cables more easily through tight spaces or behind the motherboard tray. This helps you achieve cleaner cable management in smaller cases. If your case has a long distance between the PSU mount and the motherboard, this cable bridges that gap without forcing sharp bends that might damage wires.

Wire AWG: 18AWG

The American Wire Gauge number indicates thickness. An 18AWG rating means the wires are thick enough to handle standard motherboard power loads safely. Thicker wires reduce electrical resistance and heat buildup during high usage. This ensures stable power delivery to your CPU and board components. You should look for this gauge when prioritizing safety and efficiency in custom builds.

Sleeve Tube: PP Material

PP stands for polypropylene, a durable plastic used for the outer sleeve. This material protects the internal wires from abrasion and heat. It keeps the cable organized and prevents individual wires from fraying against sharp case edges. The sleeve also adds a uniform look to your build. You benefit from longer cable life and a cleaner aesthetic compared to bare wires.

Conductive Resistance: 0.01 Ωmax

This value measures how much the cable resists electricity flow. A maximum of 0.01 ohms is very low, meaning minimal power loss. Lower resistance ensures your motherboard receives the full voltage from the power supply. This is critical for system stability under load. You get efficient power transfer, which helps maintain consistent performance for your processor and other connected components during intensive tasks.

Build Quality and Physical Design

The listing specifies a black finish for this extension cable. The connector housing is designed for a 24-pin male-to-female connection. This standard layout ensures compatibility with most modern motherboards. The cable features a sleeved tube made from PP material. This polypropylene sleeve protects the internal wires from abrasion. It also gives the cable a uniform, premium appearance inside your case.

Wire gauge is listed as 18AWG with a 2.1mm diameter. The conductive resistance is capped at 0.01 Ωmax. These specs suggest the cable can handle standard motherboard power loads without significant voltage drop. The total length is 19.68 inches. This provides ample slack for routing through tight chassis spaces. You can manage cables more easily behind the motherboard tray.

According to the listing, the physical dimensions are 13 inches in length, 4.7 inches in width, and 0.4 inches in height. The unit weighs 3.2 ounces. This lightweight design does not add noticeable bulk to your build. The black color blends well with standard PC cases. If you prefer other colors, the brand offers variations in white, red, and blue. This allows you to match your specific aesthetic preferences while maintaining the same structural specifications.

Setup and daily use guide

Installing this cable is straightforward if you follow the physical dimensions provided. The listing states the cable measures 19.68 inches, which is approximately 500 millimeters. This length gives you extra slack between the power supply unit and the motherboard. You can route the cable through tight spaces or behind the motherboard tray with more ease. The connector type is a 24-pin male to 24-pin female interface. This standard configuration ensures it works with most modern motherboards that use the ATX 24-pin power header. The wire gauge is listed as 18AWG. This specification indicates the thickness of the internal copper conductors. A thicker gauge generally supports higher current loads without significant voltage drop. The sleeve material is polypropylene. This plastic tubing protects the wires from abrasion and heat. It also provides a uniform black appearance that matches the connector housing. When you connect the cable, ensure the male end plugs firmly into the power supply and the female end into the motherboard. The conductive resistance is capped at 0.01 ohms. This low resistance value suggests efficient power delivery with minimal energy loss as heat. Daily use involves leaving the cable in place once installed. The sleeved design helps keep the cable organized and prevents individual wires from fraying over time. The black color blends well with standard PC cases. You do not need to adjust settings or install software. The physical connection handles all power transfer. If you need a different color or length, the brand offers variations in eight colors and multiple pin sizes. However, for this specific 24-pin black model, the setup remains a simple physical plug-in process.

Before You Buy This Cable

You should verify your case layout before purchasing. This 19.68-inch extension adds significant slack between your power supply and motherboard. It helps in tight spaces, but you must ensure your case has enough room for the extra length. Check your motherboard’s 24-pin socket to confirm it accepts standard male-to-female connections. The cable uses 18AWG wire, which supports standard power loads for most builds. You do not need special software or drivers for this passive component. Maintenance is minimal; simply keep the PP sleeved tube clean from dust. This product fits into the broader category of PC Power Supplies & UPS accessories. It complements your main unit by improving cable management rather than providing backup power. Consider this alongside other extension options if your current cables are too short. Ensure the black finish matches your build aesthetic. This cable is a straightforward hardware addition that requires no complex setup.

Check before you buy

• Confirm your motherboard has a standard 24-pin socket.
• Measure your case to fit the 19.68-inch length.
• Check if the black color matches your build.
• Verify your PSU cable is a standard 24-pin male.
