    Goes in the A tier list of Power supplies that Linus Tech Tips has included. Got it for a heavy discount on Prime Day and just could not say no to it at that price point.

    This is a great power supply for anyone that needs more power. Its fairly quiet, easy to install and the modular cables are good quality. Exactly what I expected from Corsair.

    I will come back an edit this after I have had it longer and can run it through its paces. I love it so far looks really clean with the white an black build I am doing for my first gaming pc. Packaging is all good and no faults booted up my motherboard and the parts I have so far. Just need to get the the processor and aio cooler and I will be able to start to tinker with this further.
