    This PSU was the biggest nightmare I have had in almost 30 years of building my own rigs. I purchased the CX750M and the short version is that it could not power my 3 year old Nvidia GeForce 1060 at load without lock up’s or completely rebooting my PC in the middle of a game. After some part swapping and software load testing I finally determined that the GPU had to be plugged into the top connector to get enough amperage to run. I am speculating that there are at least two 12v rails in this unit that power each row of connectors and the amperage is too low to power an aging GPU, 1 SSD, 1 HDD and a DVD drive. No way am I spending this kind of money when to have something this flaky in my PC, so back to Amazon it goes and I will await my new PSU from another manufacturer. I’ve attached a photo showing the bottom row completely filled which caused the errors, and where I had to move the GPU plug to get it to work. Hopefully this can help someone stuck in a similar situation.

    OK, no dudo de la calidad y la eficiencia qué tiene corsair en sus PSU. Sin embargo fui uno de los desafortunados que se encontró con una fuente de poder defectuosa y me estoy dando cuenta que no soy el único por aquí. Desde el día en que llego el pedido noté algo raro, a pesar de que el paquete venía sellado, la fuente presentaba un ligero raspón cerca del logo de corsair. No le di mucha importancia pero
    desde el primer día empezó a fallar dándome reinicio aleatorios, la pc se apagaba por completo y volvía a encender. Hice un diagnóstico completo qué concluyó con una PSU dañada. Pues incluso al encender la fuente sin conectarle nada el problema seguía presente. Lastima, había escuchado buenas reseñas de esta PSU pero creo que de ahora en adelante tratare de evitar las fuentes marca Corsair, al menos en esta gama ya qué por lo visto sus estándares de calidad no son tan altos, pues a pesar de que del producto era sellado de fabrica, tenia marcas notorias de mala manipulación a la hora de manufactura o almacenar.

    Product lasted 20 months, but has a 5 year warranty. That is the good part. Then comes trouble trying to get replacement. You must open trouble ticket with Corsair, but website won’t let you register. Called support desk, and they won’t help without support ticket. Called customer service, who also could not get an account to register. Finally created an account, and opened support ticket. Says you will get response within 24 hours. The response is, “we got your ticket”. 5 days later, no response yet from support. Going to purchase different PSU in meantime, but guarantee that the support response will be to test it (done already), then we must return it, then we must wait 1-2 weeks for replacement. Don’t buy this thinking it must be reliable due to the 5 year warranty. Buy a cheaper one that you don’t mind replacing when it dies.

    I just got this on 12/21/19. I ordered it on 12/10/19 and was supposed to get it on 12/12/19 but amazon manage to lose my order and said it was delivered. Anyways I installed it 12/21/19 at 6:00pm it was working great. 12/22/19 still working well. 12/23/19 at 10:26am it blew up and a whole lot of smoke just started coming up. Pretty upset about the whole process. Overall I won’t buy the same model.

    I tried to get involved with CORSAIR’s damage claim department. They aren’t very clear or thorough. It’s like they don’t want to help you. Your power supply blew up my computer and it took you a long time to answer me back. I have to continue on complaining just so I can be heard which is ridiculous. They couldn’t help me because the original power supply was blown and I asked for a new one thinking it was just faulty but when I got the new one nothing worked. Corsair even though you’re in the bay area CA I am never supporting or buying your stuff anymore. I have bought items before but not like this. I don’t respect your customer service. I feel like there isn’t any integrity. I took a fat L but I’ll get back up. I had a hard time with amazon’s customer service as well as Corsair’s customer service. I never want to be dealing with that again. Good bye Corsair.

    Its simply awesome; 5yr warranty,sleeved cabling(none of that ketchup and mustard crap),an LLC resonant converter on the primary, 449w on the 12v and dc-dc generation of both minor rails coupled with sub 30mV ripple on all rails with excellent voltage regulation and good enough caps(primary side uses Chemi-con, all caps rated@105°C) kept cool by a rifle bearing 120mm fan.

    Basically this thing is good enough for an i7 8700/R7 1800X + 1080Ti rig if you aren’t overclocking.

    While it might not measure up to expensive corsair RMX, Seasonic Elite or Superflower Leadex PSUs;
    The internals this thing has just blows all of the competition(eg; the Antec VP ,CM Masterwatt ,Corsair VS etc) out of the water and into the burning sun.

    A detail to be noted that this unit is dual sourced; so you might either get one made by CWT or Great Wall,rest assured both are equally good.

    -Long term update; Its been chugging along just fine for the last 2yrs on my gaming PC.

    I installed everything perfectly fine, as I have experience building many PCs. I had a bad experience with a previous Corsair product, but decided to try a corsair product anyways. After the first day, My PC started shutting down randomly and starting up again. First time I thought it was just my outlet possibly. Second time I started to investigate.

    After about a few times of trying to diagnose the problem, I decided I wasn’t going to risk my parts trying to figure it out. I thought maybe it was my motherboard, but had an idea that it most likely was the PSU. I ordered an EVGA PSU and this thing has been working wonderfully thus far. I’m glad the Corsair PSU didn’t fry my things.

    Corsair, your products just keep failing me. First time PSU bad experience, but a second time in a row? Never paying for your products again.

    Its a PSU, it is semi modular, as in that aside from the connections to the motherboard itself, the accessory cabling is plugged in to use, so you only use the cables you need. The modular cables are of the flat variety, so this could be a positive or a negative, depending what your view on the differing cable configurations out there are.

    One word of advice, and this goes with ANY PSU that you install, please ensure you install the PSU with the cables supplied, do NOT be tempted to reuse the cables from your old PSU (going to the various drives and accessories) if this is a replacement. Sadly there is no set “standard” for the PSU side of the cable, unlike the drive end. If you try and re-use the installed existing cables, and the pin-out doesn’t match on the PSU end (multi-meter can confirm if you really want to know) you could fry every component you connect to this. Even if the cable actually fits into the PSU it does not mean they are compatible by any means. Some people have come to find this out the hard way, and have thankfully shared their experience for everyone to learn (I am glad I checked before install)

    Installation went as you would expect, it fit my case well, is the same dimensions as the 700w supply it was replacing. I cannot attest to the longevity of this unit yet, but will try and remember to update this in the future, once it has some hours on it. Good price, good brand and an easy install. what more can you ask?

    Llevo utilizando la fuente aproximadamente 2 semanas desde que armé mi primera PC, fue algo que quería hacer desde hace tiempo y pensé: ¿por qué no?. Funciona excelente, no he escuchado ningún ruido, es muy silenciosa, además me gustó que los cables no vengan de colores, vienen todos en color negro y es algo que a mi me gusta ya que hace lucir más la estética cuando todo está armado (gusto muy personal), sin mencionar que como es modular, es más cómodo el solo conectar los cables que necesitas y guardar los demás para otra ocasión. La única razón por la que le doy 4 estrellas es porque no viene con ningún manual de conexiones, tienes que guiarte con el manual de la tarjeta madre y la forma de los conectores, debo admitir que tuve miedo al encenderla aunque todo hiciera el famoso “click” al conectarse ya que no estaba 100% seguro de que todo estuviera en su lugar.

    Por último y es algo que puede le puede pasar a alguien más que este armando su primera PC, es que el cable de alimentación de la placa madre, el de 8 pines (NO el de 24) puede ser divido en dos de 4 pines si estiran un poco hacia los lados. Es algo que tampoco mencionan ya que como digo, NO viene manual, yo me asusté mucho al ver que el cable tenía 8 pines y mi placa solo aceptaba 4, hasta que me encontré un video donde hacían esto que les digo de separarlo con las manos, en fin, me tomó mucho tiempo sin un manual por no estar seguro de como iba avanzando.

    El envío fue impecable como siempre.
