    All good so far. Strong enough for my setup of 10600K, 1080 Armor (not TI). Haven't pushed any overclock. But with stock everything, it runs smooth, quiet and cool. Definitely would suggest to anyone.

    Modular, fantastic price and works rock stable. PC was suffering from issues with the pre-assembled PSU and so upgraded with this. PC hasn't crashed once and is working rock solid.

    Amazing PSU. I had horrible coil whine from my 3080 ti using 2 other name brand PSU's. Once this was installed it completely went away. Totally recommend

    A little more power than I needed for my PC build, but it was on sale at a decent price so I went ahead and splurged. Great performance and very quiet. Nice!

    Overall very good PS. No issues with it, only loses one star due to a bit of fan noise at low usage with hybrid mode turned off. This will only be noticeable if your PC is close and all of your components are built for silence (GPU no spin fans at low load, low rpm silent fans, etc.).

    I like this power supply because it's definitely have all the features I need from a power supply. My previous power supply from Corsair honestly didn't cut it, I paid a premium for a gold rated one with the same amount of wattages as this platinum one at the same price. But you live and learn. I'll be rocking with this power supply until I build a computer that requires more power if needed.

    Good PSU, quality components and cables (though I do wish the 6+2 pin (8 pins) would join together easier.
