This article promises to be quite explanatory and theoretical. Today we will take a closer look at the subject so important in our time of technology - the adapter. This will be the SATA Molex adapter ("SATA Molex"). In this article you will find answers to your questions, for example, what it is, what it is intended for, what function it performs, and others.
SATA Molex
To begin with, SATA is just an abbreviation, but somewhat obscure. In relation to computer technology, the decryption will be as follows - Serial Ata The Acronym. Speaking simply and clearly, SATA is a serial interface that appeared in 2003. He replaced the IDE connector (IDE), which was later renamed to PATA (Pata) - parallel ATA, as it was a faster connector, suggesting data transfer at a speed of up to one and a half gigabits in one second. This also explains the physical change of the direct connection to the hard drive, which resulted in the need for a special device. Here we are talking about the SATA power adapter (SATA). It is needed to connect new hard drives to old computers that do not have such a connector.
Why do I need a SATA Molex adapter ("SATA Molex")?
Today, all modern computer power supplies have a Molex connector. Despite this, the SATA Molex adapter ("SATA Molex") itself has relevance and a fairly high demand to this day. Why? For example, you want to install additional equipment on your personal computer in the form of hard disks (or as an additional CD drive). However, the available free SATA power connectors are already taken. What will you do in this situation? You will come to the rescue adapter SATA Molex ("SATA Molex").
What it is?
In fact, the SATA Molex adapter is the simplest device, which consists of two connectors for connecting to connectors interconnected by four cable segments. Previously, devices with a Molex connector were powered using the following four contacts: + 5V; Earth; Earth; +12. The SATA power connector has fifteen pins. It is divided into five groups and has a sequence of + 3.3V; Earth; + 5V; Earth; + 12V.
There is also a less common SATA Molex adapter ("SATA Molex") for connecting power to a laptop CD-ROM drive. This device has a more compact connector due to the fact that it has only six + 5V contacts (instead of fifteen) and ground.
Pinout
Let's take a closer look at Molex SATA (adapter). The pinout of this device, like the connector itself, is quite simple.
The first group of contacts in the SATA connector is a voltage of +3.3 volts. This group is not used in the adapter, since the Molex connector has absolutely no such voltage.
The second group of SATA contacts is earth.
The third group of contacts of the connector has a voltage of +5 volts. It should be noted that it is combined with the first contact.
The fourth group of contacts of the connector is ground, it is combined with the third contact of Molex (molex).
The fifth group of contacts of the SATA connector (+12 volts) is combined with the fourth contact of the Molex connector.
The adapter can be purchased at any computer store or in the radio parts department. These devices have completely different lengths: from a few centimeters to several tens of centimeters. The price of the most common adapters is about one dollar. Also on sale are adapters not only one to one. There are adapters from one Molex connector to several SATA connectors. This is very convenient in cases where all of the free connectors on your power supply have run out, and there is only one Molex (molex) available, but you need to turn on several SATA devices. Here the device already described in the article will help you.
