    Well if you get all your hard drives sata solid date and tradition spinners used fried by this Psu. You would not have anything good to say about this company or it’s products. This is definitely due to poor qc out of the factory .

    Giving it a 1 star review because i cant give it a 0. Terrible product havent even had it a year and it completly died on me. Hopefully it didnt fry anything else. Would not recommend anyone buy this if you plan on using your computer long. Go buy something like a corsair.

    Did not work. Had to return. I have a 500w thermaltake that's worked for years and needed to upgrade, but this one unfortunately never worked for me.

    I’m sure it’s a great power supply but my unit was DOAz. I’d recommend going with Corsair. Never had issues with Corsair power supplies.

    This is an excellent power supply. It's fully modular and quiet. If you need a new power supply or a higher wattage power supply, this is easy to recommend.
