Hi, thanks for your response. One more question: if I install a Ryzen 7 2700 in the future, will I fall short of power? Cheers

Hi everyone, I have a question regarding my PSU CX550W. Is it enough to power an RX580 8GB GPU and a Ryzen 5 2400G? I read out there that I must pay attention to the amperage that comes out of the 12v line but I didn't find the official data. On the other hand, I would like to replace the CPU with a Ryzen 7 2700, and I fear that the PSU can no longer support it. It is right? Thanks

Hello again. I understand what you say. Many mechanical problems are solved with empirical rather than theoretical knowledge. It does not intend to disregard the advice I have received in this forum. As I explained before, I need to learn in order to develop a rational approach. I think this is one of the dark sides of the technological society in which we live. The abundance and ease of consumer goods facilitate user complacency. Most people do not bother to learn the operation of the electronic devices they use daily. So we have a paradox: on the one hand we have high rates of computer integration in our daily lives, but at the same time we are functional digital illiterates. For example, children are familiar with smartphones since they are born, but they have no idea what an operating system is. I am 31 years old, and for my generation it was different. When I was a kid, in elementary school I had my first computer classes, using command lines in MS-DOS. It may seem silly, because shortly after the desktop environment of Windows 95 appeared, so, what could serve me learn command lines? But it was a very useful experience, because now in my job, when something goes wrong in the system, I am able to at least try to repair it. In my country the government has invested money to equip public schools with netbooks, but most importantly I think they have been programming courses for children. Going back to my current problem, I investigated a bit. First, I'm not the only one confused by the incongruous pattern of certain EPS connections, as you can see: - https://forums.tomshardware.com/threads/4-4-cpu-connector-does-not-seem-to-fit-the-atx12v-8-pin-connector.2183393/ - https://superuser.com/questions/778356/12-volt-motherboard-power-connector - https://www.overclock.net/forum/31-power-supplies/1239449-seasonic-x660-gold-issue-12v-connector.html I also found some technical documentation: - http://www.enermax.cn/enermax_pdf/EPS12V%20Spec2_92.pdf - http://www.playtool.com/pages/psuconnectors/connectors.html http://g01.s.alicdn.com/kf/HTB1CPCIFVXXXXbqXVXXq6xXFXXXm/200304538/HTB1CPCIFVXXXXbqXVXXq6xXFXXXm.jpg I did not have much time to read the documentation, but some pins deliver electric current and others are ground. It does not seem that the shape of the connector is related to this. Therefore, if I understood correctly, as long as the 12v pins and the ground pins coincide between the EPS of the PSU and the ATX of the motherboard, everything is OK. The problem is that all the cables of the CX550W are black and I can not distinguish between 12v and ground (yellow and black, respectively, according to the standard). I will continue investigating when I have more time. Thanks for your time. Greetings from the land of the barbecue and football (soccer)

Hola, gracias de nuevo. Este es el mail que recibí: En cuanto a la forma de los conectores, por lo que estuve leyendo, algunos son "amarillos" (entregan 12v) y otros son "negros" (tierra). Me parece que no me conviene conectar cosas donde van. Saludos

Thanks for your answer. But perhaps the problem is precisely the other way around. No one has yet given me a concrete answer to what I am asking. Yes, you tell me that I must connect it and that it will be fine. But nobody can explain why the pins have different shape, nor what is the logic that I must follow to operate my hardware safely. I am cautious because I can not risk losing my hardware warranty. I just thought that there were people with more knowledge here, capable of teaching me. I need a technical explanation to be able to learn. It seems that no one really knows how the EPS connection works. You, for example, only tell me that everything is fine without a reason, it is a matter of faith. Anyway, I appreciate your attention, it's just that I need technical information about my hardware to understand how it works. Greetings.

Hola, gracias por responder. Inicié un ticket hace una semana aproximadamente, todavía no he recibido respuesta. Quedo a la espera. Mientras tanto, ¿podrías explicarme por qué los conectores EPS 12v 4+4 tienen 6 pines "redondeados" y 2 cuadrados, mientras que las conexiones ATX 12v de las motherboards tienen 4 "redondeados" y 4 cuadrados. Porque ese es el problema. Ustedes pretenden que conecte pines de diferentes formas entre sí, lo que es completamente anti-intuitivo en términos de hardware. Gracias

Hello, a pleasure to meet you. Thanks for your answer. As I said, the "D" shaped pins can fit in the squares, but they have different shapes, so it is reasonable to assume that they should not be connected to each other. I still do not understand the most important thing: can I connect a rounded pin of the PSU to a square pin on the motherboard? I need someone in Corsair to explain it to me, because in terms of hardware, the common user (like me) should not assume that two different connectors are compatible. They are supposed to be different for a good reason. I hope I have expressed myself correctly. Regards

Thanks for your answer. But I prefer do not try to do it for my self, because I can broke something (and miss my warranty). Also I think that my PSU should to be compatible, I mean, I paid for a quality product. Excuse my english, I'm Argentinian, my native language is spanish. I note that "rounded edges" actually fits in "completely squares edges", but no one in Corsair, Gigabyte or AMD is capable to explain to me the important of the difference in the shape of the pins. It is reasonable to assume that pines of different shapes should not be connected to each other, even if they fit together. So, does anyone here have a remote idea about how these pins work? Thanks again.

Hello! Nice to meet you. Do you realize that the pins on the right connector do not have the same shape as those on the 8-pin connector on the motherboard?? Pay attention to this diagram: http://oi65.tinypic.com/25akk0y.jpg The EPS connector from the CX550W doesn't fit completely in the motherboard's ATX 12V connector. Please read this too: Now, Anybody in Corsair can explain this to me? Because this PSU has been a waste of money for me. I can only feed the processor with 4 pins. It may be enough for the Ryzen 5 that I have now, but ... what will happen in the near future when I decide to update it for another more powerful processor with higher power requirements? Thanks!

Estimados, mucho gusto. Compré una fuente semi-modular CX550W para alimentar un Ryzen 5 2400G en una mother Gigabyte B450M DS3H. Resulta que el cable que sale de la fuente tiene dos conectores de cuatro pines (4+4), pero sólo uno de ellos es compatible con la conexión de 8 pines de la mother, el otro no. http://oi68.tinypic.com/r272pz.jpg ¿A qué se debe esto? Yo pensaba que las conexiones de 8 pines eran universales. ¿Puede funcionar al 100% de su capacidad el procesador con sólo 4 pines conectados? El PC enciende, pero estoy desconcertado con esta falta de compatibilidad que no esperaba. Saludos y gracias.

Hi everyone, I have the same issue with a CX550W PSU and a B450M DS3H motherboard. The PSU's output has eight pins (4+4) but only one of them is compatible with the 8 pins' conexion in the motherboard. http://oi68.tinypic.com/r272pz.jpg I'm surprised, I guessed that conexions were universal. The PC turn on and work. But I'm still doubt: can I use the CPU at 100% with only 4 pins connected? Thanks, and excuse my english, I'm Argentinian, my native language is spanish. PD: It's seems like this issue is common in Gigabyte's motherboards, right?
