    I love Corsair peripherals, but I never considered their psu’s. Top tier quality in terms of capacitors and rails. Great for mid - high end gaming builds. I personally use an i7-8700k and a 2080 Super and I have plenty of room for overclocking. This isn’t for you if you’re going for a budget build, there are much cheaper options with nearly similar performance.
