    Great Power Supply.

    I read many reviews of power supplies available both locally and online. This power supply was used to replace an Antec PS that died after many years of faithful service. This power supply was available at an online retailer at a lower price and Best Buy matched the price with no problem. Replaced the failed power supply and everything restarted normally.

    Came with one of the sets for the PCI-E slots non functioning. So if I want to SLI I have to take it back into the store! and the teeth on another one of the peripheral slots was broken. Seriously do some quality control before you send them out.

    What's great about it is that it makes absolutely zero noise, plus is modular so you can hook up the connections you actually need so you won't have a cable mess inside your case. Recommended~!

    I've had this for about 3 years now and it's still running great. Less clutter with the modular design definitely helps with airflow and cooler temps overall.

    Great PSU!!

    This reviewer received promo considerations or sweepstakes entry for writing a review.

    I bought this PSU in 2013 on sale for $80 and I'm still using it today. I have not once ever had any problem out of it and I highly recommend. When I bought it, I was running 2 HD 7950s for crypto mining. Today I am running one RX 580 as main gaming GPU and one of the same old HD 7950s for a second display. As I said, I have never experienced one issue with it.

    Works great and powers my rig easily. Only concern is that there is some coil whine when playing high intense games but its not to big of a deal.

    Great Power supply. I replaced my old Antec 650 EarthWatts, because my system was becoming unstable. My only complaint about the unit is the number of individual sata cables you can attach, and it appears that this PSU is made to place in the bottom a a case. The spot for my PSU is at the top of the case and in order to attach the cable to my sata drives I had to turn each connecter upside down. Kind of annoying but not a deal breaker.
