The connectors contain 3.3V, 5V, and 12V rails. The cables used are actually rated to 4.5A per supply rail. 1.5A may well be a real supply requirement, though. The measurement allowed error is +/- 1-3cm. KiekerJan 71 1 1 5 Add a comment 3 Answers Sorted by: 7 As bitshift says, you'll likely need to get the actual spec to be sure. It provides an inexpensive solution compatible with adding more connections to an existing power supply with limited SATA power ports.Computer tower cable management solution2.5inch SSD or 3.5inch HDDOptical DVD drivePCIe express cardName: sata power cordPower Supply: 3.3V, 5V, and 12V PSU18 AWG wire gaugeColour: multicolorMaterial: PVCSize: 15cmPackage Contents:2 * Sata power cordOnly the above package content, other products are not included.Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. Can anyone confirm whether my suspicions are correct, and it is impossible to power a SATA drive from a PCIe connector?Īnother possibility I'm considering is whether I can use a couple of y-adaptors to split the power supply to my two existing 3.5" HDDs in order to provide power for the two additional drives.Snug-fitting drive SATA connector and channel guides on the power supply connector provide a secure connection that won't accidentally disconnect.UPGRADE COST SAVER SATA power cable spares the expense of upgrading an existing power supply to connect a new SATA drive Cost-effective 2-Pack provides spare SATA extension power cables compatible with new installations or repairs.DIY or IT installers both appreciate the convenience of sharing a PSU connection when installing new internal components like a DVD burner 15cm cable harness (not including connectors) provides sufficient length compatible with internal cable management in most configurations.HEAVY DUTY SPLITTER with 2 SATA 15 pin female connectors and 1 SATA 15 pin male is constructed with flexible 18 AWG conductors compatible with reliable percompatible withmance when connecting two SATA hard drives to a power supply Supports 3.3V, 5V, and 12V power voltages between SATA I, II, III drives and power supply connections without any degradation of percompatible withmance.COMPATIBLE with popular SATA equipped devices such as: Apricorn Velocity Solo x2 Extreme Percompatible withmance SSD Upgrade Kit, Asus 24x DVD-RW Serial-ATA Internal OEM Optical Drive, Crucial MX100 256GB SATA 2.5-Inch Internal Solid State Drive, Inateck PCI-E to USB 3.0 5-Port PCI Express Card, Inateck Superspeed 4 Ports PCI-E to USB 3.0 Expansion Card, Inateck Superspeed 5 Ports PCI-E to USB 3.0 Expansion Card, Inat.The 15-pin SATA Power Y-Splitter Cable is an indispensable tool when building, upgrading or repairing computers. I suspect that there is a good reason for this - my understanding is that PCIe power connectors provide ground and +12V pins, whereas SATA also requires a +5V pin (and possibly +3.3V as well for old drives). this), but so far I haven't found the converse (i.e. I've come across various SATA-to-PCIe power adaptors (e.g. This adapter will remove the 3.3V signal. ![]() The machine has a 685W power supply - my intuition is that if the PSU is designed to provide enough power for a second graphics card then it should probably be able to handle a couple of extra 2.5" HDDs (which would should only draw about 3-4W apiece) but I admit that I have not done all of the math to confirm this. You can totally bypass the 3.3V rail (which after all isnt used in HDDs) by using a simple 4-pin Molex-to-SATA adapter to supply power to the HDD. ![]() ![]() The only spare power connector on the PSU is an 8-pin PCIe block designed to provide power for a second graphics card. Order Intel NUC SATA power cord & cables which includes 1.25mm pitch 4 Pin to 1.5mm pitch 5 pin cable, and 10 pins HDG to 10 pin HSG connectors to get. I have two free SATA ports, but I'm struggling to find a way to provide power for the additional drives. I have a Dell Precision T3610 workstation that currently has two 3.5" SATA HDDs installed, and I'd like to add two more 2.5" disks in a hot-swap bay.
