★★★★★Just a great product
Had my previous corsair psu for about 5 years with 0 issues, bought this one due to needing more power for my rig and these always perform great for the price

★★★★★Reliable, quiet, and easy to cable manage
This is a high-quality power supply and exactly what I expected from Corsair. The fully modular cables make the build much cleaner because you are not stuck stuffing unused cables into the case. It also feels solid and well made. It runs quiet and has enough power for a strong gaming setup. I like using a good power supply because it is one of the parts you really do not want to cheap out on. This one feels dependable and should last through future upgrades.

★★★★★The fan speed adjuster is a gamechanger
Great powersupply overall. I like the ability to increase the fan speed if need be.
