Featuring a sleek all-black design and 12-inch length, it simplifies cable management by eliminating the need for PSU Molex connections while ensuring compliance with RoHS standards. Ideal for professional PC builders seeking clean, efficient power solutions with a focus on modern motherboard capabilities. ## Description This cable is as simple as it appears. Power watercooling pumps and other 12V 4-pin devices using a fan header. The output current is limited to the capabilities of the fan header that this cable is connected to. Modern PC motherboards are now commonly available with higher output current capacity fan headers (W_PUMP+ fan header on ASUS motherboards as an example). Due to the possibility of connecting things not intended for a fan header the exercise of due diligence is absolutely necessary. Please reference the manufacturer documentation of your devices to avoid current overdraw. ## Features - Designed specifically to eliminate the need for a power supply 4-pin peripheral molex connection due to the high output current fan headers found on many modern ATX motherboards. - Compatible with 4-pin peripheral molex power water pumps and other 12V input devices (please exercise due diligence to avoid damage from current overdraw and disable 3-pin fan speed control in BIOS to ensure 12V output from the fan header) - RoHS Compliant. Each cable is constructed with all black connectors and high density black sleeving for minimal wire visibility. - NOTE: Please take care to align the pins when making the 4-pin peripheral connection as they are under some tension from the sleeving. - Total cable length (including connectors) is 12 inches (30cm) ## Technical Specifications | Specification | Value | |---------------|-------| | Brand | CRJ Electronics | | Material | Polycarbonate (PC) | | Item Weight | 0.01 Kilograms | | Connector Type | 4 pin | | Wire Diameter | 0.64 Millimetres | | Manufacturer | CRJ Electronics | | UPC | 850028770047 | | Model number | 4058 | | Item Weight | 9 g | | Package Dimensions | 12.5 x 7.39 x 0.89 cm; 9 g | | Item model number | 4058 | | Cable Interface | Fan Header Cable | | Compatible Device | Personal Computer | | Are batteries included? | No | ## Product Details - **Brand:** CRJ Electronics - **Material:** Polycarbonate (PC) - **Item Weight:** 0.01 Kilograms - **Connector Type:** 4 pin - **Wire Diameter:** 0.64 Millimetres ## Images ![CRJ Fan Header to 12V 4-Pin Peripheral Molex Power Adapter Cable for Fans and Water Pumps - Image 1](https://m.media-amazon.com/images/I/61PBsvnrGxL.jpg) ![CRJ Fan Header to 12V 4-Pin Peripheral Molex Power Adapter Cable for Fans and Water Pumps - Image 2](https://m.media-amazon.com/images/I/71Cc7-FoJqL.jpg) ![CRJ Fan Header to 12V 4-Pin Peripheral Molex Power Adapter Cable for Fans and Water Pumps - Image 3](https://m.media-amazon.com/images/I/51sKT2Cz9+L.jpg) ![CRJ Fan Header to 12V 4-Pin Peripheral Molex Power Adapter Cable for Fans and Water Pumps - Image 4](https://m.media-amazon.com/images/I/61Fdw9j3s2L.jpg) ## Frequently Bought Together - CRJ 3-Pin Fan Header to 12V 4-Pin Molex Power Adapter Cable - 12 inch (30cm), Black Sleeved - Power 4-Pin Peripheral Molex Devices from 3-Pin & 4-Pin Fan Headers - StarTech.com Expansion Slot Rear Exhaust Cooling Fan with LP4 Connector (FANCASE), Black, 1 Count (Pack of 1) - okgear 3pin Power to 4pin molex Adapter --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.is/products/630158421-crj-fan-header-to-12v-4-pin-peripheral-molex-power](https://www.desertcart.is/products/630158421-crj-fan-header-to-12v-4-pin-peripheral-molex-power) --- *Product available on Desertcart Iceland* *Store origin: IS* *Last updated: 2026-05-25*
