![]() ![]() ATX2 o ATX 24 pines (20+4):Ĭurrent motherboards need an extra current supply, which is why this evolution of the previous one has been implemented, adding an additional 4-pin connector. It includes the different standard voltages for all components on the motherboard. It is used to supply power to ATX motherboards thanks to its 20 pins. It is a fairly old connector and currently in disuse, introduced in the 90s. The EPS will supply an additional 12v of power for those boards with more chips, 4 and 4 can be connected separately, or together to form an 8 pin connector. Since it is intended more for servers or workstations with motherboards that have more than one socket, that is, MP systems. It is a connector that we will not easily find on PCs, Not to be confused with the 8-pin PCIe, despite their resemblance they are different. If it didn’t connect, in many cases it would work but at lower performance.After this modality, the 8-pin modality was devised, which has the same connection, but in this case it can reach powers of up to 125 extra watts. These types of high-end graphics cards demand large amounts of power, so the 6-pin connector can supply an extra 75w by connecting it directly to the connection provided by this type of card. ![]() As you can imagine, it is used to supply extra power to the most powerful PCIe graphics cards. The PCI Express connector can be found in two modes, one with 6 pins (4+2) and the other with 8 pins. This type of connector is thinner than molex, and has more contacts to supply power to SATA or newer hard drives and drives. It is a more modern connector that is displacing the previous one. On the left we have an example of a male and on the right the female. You can see both connectors in the image above. Like the Berg, it also has 4 wires and 4 contacts, but its size is larger.īy the way, you should know that there are male and female types. The molex is the most typical of the connectors, since it is used to connect IDE ATA drives such as CD, DVD, BD drives, hard drives, etc. It is small in size and has 4 cables, two for ground and another for +5 and +12v. The Berg connector is an old connector used for the floppy drive. We are going to see some of the connections of the most popular power supplies in current systems, their characteristics and what each one is for: Berg: If this is not the case, we will have a power supply that we will have to repair or replace. Knowing this, by inserting the tips of our multimeter into the contacts of the connectors, we will be able to know if the voltages are what they should be based on the color. Purple : Lastly, we have the +5v for the Standby state. ![]()
