    I won't put anything in my builds, or builds I do for others, other than a Seasonic PSU. Used them for years and have never had any issues. Not saying there isn't any other reliable brands out there, as I know there are, but I'm sticking with what has worked for me.

    What a Coincidence! I bought this very same Seasonic 650PX Power Supply and just last night finally took it out of the box to prep for my new build...and here I find a review for it!!

    The author makes an excellent point that a 2nd modular EPS cable really should be standard these days. With motherboards now supporting USB 3.1, integrated WiFi, a whole slew of 2A fan/pump connectors and tons of other power-drawing features which hardly even existed a decade ago, a second EPS is quickly becoming the norm rather then the exception.

    In my case, with the very popular ASrock Taichi Z series motherboards which requires three connectors (1x24, 1x8, 1x4), I need to obtain a second additional 8pin to 2x4 modular cable. I just happened to contact Seasonic about that not an hour before seeing this review and learned that www.btosinte.com is their approved distributor and that such a cable costs about $5.00

    If you do need to buy an additional EPS cable, BE SURE TO GET THE ONE WITH THE INLINE CAPACITOR, for the newer SSR series!!

    It was interesting to learn from this article that providing a second EPS cable isn't really typical for most vendors 650W power supplies, which makes me feel better about being in that predicament with Seasonic. I was initially a bit disappointed, but then I've never had a Desktop mobo which required so many connectors before.

    All that being said this appears to be an outstanding power supply, a great value, and given that my previous modular Seasonic Power Supply is still running great after more then 6 years, I remain a Seasonic customer until proven I shouldn't be.

    I am insisting for quite some time for a second EPS connectors in high-end PSUs and your post clearly shows why. Thank you!
