Faster installation and better-looking buildsThe modular cabling system lets you use only the cables you need. You get to save space and reduce clutter for a cleaner-looking build and improved airflow. |
Good looksThe matte black finish, black-sleeved cables and black connectors help give your system a restrained, high-tech look. |
Modular cabling systemSince the peripheral power cables aren’t hard-wired to the power supply, you can connect only the cables you need for your exact configuration of PCI-E cards and storage devices. The rest of the cables stay in the box, and not in your PC’s case where they can add to the clutter and interfere with airflow. |
Large-diameter, thermally controlled fanOnce you’ve installed a PSU, you shouldn’t have to think about it. Employing a thermally controlled fan makes the CX Series Modular quieter at idle, and the large diameter reduces noise even when you’re pushing your system hard. |

PROs
1...does what it needs to for range of voltage given
2...has real modular cables for sata
3...good build quality given its price range
4...very short. old power supply was at least a inch longer and the cables plugging in to the power supply itself can bend to fit tight spaces
CONs
1...it has 2 cables for GPU's that are both 6x2 pin set ups (4 8 pin plugs total as there are 2 per-cable) when real world it only needed 1 of these cables as most systems wont run SLI or crossfire with only 650 watts total. real world it should have had 3 sata cables and not 2 GPU cables
2...sata cables are a pain. the flat cables i just do not like. yeah they bend but they dont make in to tight places like sleeved cables do. you get 1 sata cable with 4 sata plugs and 1 cable with 2 sata plugs. should have been 3 sata plugs on each. other problem is the 1 cable with 4 plugs has them really close to each other. depending on your case you may only be able to use 2 or 3 of these plugs on the 4 plug run.
3...still has a 3.5 floppy drive power connection on the end of the molex cable....what is this 2003???
4...does NOT come with a extra 8 pin or 4 pin CPU power cable even when 2 slots have CPU power written on them. reason to remember this is the fact a ton of newer motherboards have a 8 pin PLUS a 4pin OR can have 2 8 pins just for the CPU! (i just built a system that had 3 8 pin cables for the CPU) they sell the cable as a option but you have to order it from Corsair.
5...nothing to do with the power supplies but when it shipped, it was only in its normal retail box. power supply its self is the size of the box and they only put small bubble wrap on it from Corsair
in conclusion....its a good option to have and will do its job. if you dont need anything more then a single 8 pin for your CPU and can deal with 4 sata plugs on 1 cable you should be fine using this. my biggest problem with this power supply is how they divided the sata cables. old power supply had 3 per cable and was perfect for me as i use it to dual boot my system. 1 cable was my main install and the other cable was my second install. to switch boot order, i would just change the cable at the power supply (with win 10 you dont even have to change boot settings in bios if its set to windows boot manager). i could only have 2 drives on 1 install using the included cables, when i was running 2 storage drives per install. i got around this because i had left over cables from another corsair CX power supply and ended up using 2 of the 4 plugged cables.
Even while connected to an APC UPS unit, some strange brownouts caused something in the unit to begin to emit an electrical buzzing sound that only goes away after powering the PC off and turning the PSU off itself.
Decent unit if you can manage a warranty claim from Corsair after buying it here. Their website seems to only offer RMA if purchased straight from Corsair. YMMV.

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.

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.
