Style: KRATOS
Power supply works real good, power's is everything as it should, bought this because I thought it would have extra wiring for the fan's and lights in their computer case that I bought, made no difference at all, the case is nice but the fan's and lights don't work at all and are useless junk as far as I'm concerned! ... show more

    • Great product
Style: KRATOS P1A-750G
But this for my son gaming computer that he built. Definitely was worth the money spent it's a very sturdy product as far as the build the connectors are great it runs quiet the power supply provided is what he was looking for and he easily installed it. He said he likes this better than the one we were actually replacing. Only complaint was it was already going to take over a week to arrive in 2 days before delivery they changed it to another 4 days out. To me no issue but to a teenager waiting for his computer to work was the end of the world LOL ... show more

Will not turn on... what a disappointment! Update: Returned the first unit and ordered another one thinking I wont be so unlucky as to recieve another faulty unit but the second unit came in faulty as well and will not turn on despite going through all the troubleshooting steps, including the pin test and working cable test. Very disappointed. My entire setup just sitting there waiting for power. This is wasting our time waiting and returning as well. ... show more

    • Good Value
Style: KRATOS
Super basic, gets the job done, no issues. Cable length seems good for a basic build. A cheep solution for the wattage. Highly recommended if you have space to hide extra cables since it isn't modular.
