    Buena fuente de poder, muy cómoda para el tema de cableado

    Very easy to install, super quiet, comes with every single fully modular cable imaginable. Does its job perfectly and reliably (Ive had very good luck with Corsair products) Only note is some of the cables are VERY stiff and not easily bent, also as they are very thick cables it may make cable management difficult if you dont have enough space on the backside of your case.

    Some thick power cables that go from the power supply to the motherboard have wire mesh sheathing, and where the sheathings end, there are what seems to be thick heat shrink tubes to hold the ends. These tubes are so hard that the cables dont bend at all on the tubes, which can be a serious problem in routing cables inside the computer case. Also because of this inflexibility, it puts a lot more stress on the connectors on the motherboard.

    Its surprisingly quiet, works great. Came with all the cables necessary and a lot of extra depending what youre looking to power. Being fully modular it was very easy to hide the wiring.

    I know i am writing a late review. However, I couldn’t do so as i was busy with some work and then health issues so i couldn’t assemble my device. I bought the product assuming it to be a reliable product. However, it didn’t even start the first time. I thought I was doing something wrong. Then I took out my old cooler master smps to check and it worked just fine. It was then I realised that the new smps is not working.

    Was going to return this product until I realized the cord they sent for the AC outlet is too powerful for the PSU. Be weary, mine came with a 300V cable but it is only capable of producing 240V. Swapped out the cable for the proper one and it now works, side note it did cause my fan module to catch on fire after only plugging in the essentials.
