Previously, devices with a Molex connector were powered by four following contacts: + 5V Earth Earth +12. In fact, the SATA Molex adapter is the simplest device, which consists of two connectors for connecting to the connectors, interconnected by four lengths of cable. What will you do in such a situation? The SATA Molex adapter ("SATA Molex") will come to your rescue.

However, the available free ones are already taken.

Why? For example, you want to install on your Personal Computer additional equipment in the form of hard drives (or in the form of an additional CD-ROM drive). Despite this, the SATA Molex adapter itself ("SATA Molex") has relevance and quite high demand to this day. Today, all modern ones have a Molex connector. Why do you need a SATA Molex adapter ("SATA Molex")? It is needed to connect new hard drives to old computers that do not have such a connector.
Here we are talking specifically about the adapter SATA power supply(SATA). This also explains the physical change of the hard drive connector itself, as a result of which a need arose for a special device. It replaced the IDE connector (IDE), which was later renamed to PATA (pata) - parallel ATA, since it was a faster connector, involving data transfer at a speed of up to one and a half gigabits per second.

To put it simply and clearly, SATA is a serial interface that appeared in 2003. In relation to computer technology, the decryption will be as follows - Serial Ata The Acronym. Let's start with the fact that SATA (sata) is just an abbreviation, but somewhat incomprehensible. 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. This will be an adapter SATA Molex("SATA Molex").
Today we will consider in detail the subject so relevant in our time of technology - an adapter. This article promises to be quite explanatory and theoretical. Shorting pin 14 (/ PS_ON) to GND (COM) causes power supply to switch ON and PWR_OK to change to + 5V. Pin 14 goes from 0 to 3.7 when PSU switch is turned on. Pin 9 (standby) supply 5V even when PSU is turned off. In addition, some PSU violate color coding of wires. In several power supply units pin-12 may be Brown (not Blue), pin-18 may be Blue (not White), and pin-8 may be White (not Gray). PS_ON activated by pressing and releasing the power button while the power supply is in standby mode.Īctivating / PS_ON turns on the power supply. 5 VDC (2002 v1.2 made optional, 2004 v2.01 removed from specification) Short this pin to GND to switch power supply ON, disconnect from GND to switch OFF. +12 VDC (may sometimes have a colored stripe to indicate which rail it "s on) Power Ok is a status signal generated by the power supply to notify the computer that the DC operating voltages are within the ranges required for proper computer operation (+5 VDC when power is Ok)ĥ VDC Standby Voltage (max 10mA) 500mA or more typical Current version of ATX12V 2.x power supply provides two connectors for the motherboard: a providing additional power to the CPU, and a main, an extension of the original 20-pin version. Originally the motherboard was powered by one 20-pin connector. A −5 V output was originally required because it was supplied on the ISA bus, but it became obsolete with the removal of the ISA bus in modern PCs and has been removed in later versions of the ATX standard. Low-power −12 V (± 1.2 V) and 5 VSB (standby) (± 0.25 V) supplies are also required. The ATX specification requires the power supply to produce three main outputs, +3.3 V (± 0.165 V), +5 V (± 0.25 V) and +12 V (± 0.60 V).
