    5.0 out of 5 stars Excellent budget power supply
    Reviewed in the United States on December 20, 2020
    Verified Purchase
    I've now used this power supply in three different builds, all three with Ryzen 5 3600s and a mix of video card ranging from a gtx 1660 super to a vega 56 and this power supply has had no issue keeping up. While it's not modular the flat ribbon cables make cable management really easy and make tucking the cables behind the motherboard tray a easy chore. Noise level is also great you can hardly hear the fan running.

    I like Silverstone products and this P/S did not disappoint. Honestly Molex connectors are a thing of the past now and instead of wasting space with molex cables I would suggest adding 1 or 2 sata power to molex adapters instead. Had no issues with this power supply, very clean power delivery.

    I bought this during the great pc part drought of 2020. I got a quality bronze rated psu with no ketchup & mustard cables for 55$. Comes with a warranty in box and was an immediate upgrade from my evga non rated 550w psu. I honestly have no complaints.

    The media could not be loaded.
     I think this PSU had alot of potential but ive had 2 RMAs and both of them had bad fan bearings and produced a terrible noise, it was also the loudest component in my build by far. My build at load is suppose to use around 350 watts so this psu shouldnt even really be pushed. I guess its just bad luck.
