    SilverStone SX500-LG reviews

    500W 80 Plus Gold Modular SFX-L Power Supply is rated 4.8 out of 5 by 4.
    Rated 5 out of 5 by from Great Small Form Factor PSU This little guy is perfect for my Silverstone Sg13b mini itx build. Lots of power in a small package, fully modular and perfectly fit for any small form factor traveling PC. I also like that all the cables are all black instead of multi color, it gives an overall cleaner look to the inside of my case.
    Date published: 2016-11-13
    Rated 4 out of 5 by from Does it's job with one caveat When the fan is on a lower voltage/speed, an audible ticking noise can be heard. At high speed/voltage, the ticking stops. The power supply is great, small and effective. It is just the fan that there is an audible problem with. I wish that this could get resolved.

    Rated 5 out of 5 by from Good Like this small modular PSU fits great in my dads mini itx case and comes with atx adapter plate
    Date published: 2018-01-19
    Rated 5 out of 5 by from I would definitely buy this again Initial impression out of the box was that this PSU was well built and contains some quality parts inside. Unlike other cheaper PSU's that are extremely lightweight this has some weight to it, a good thing! I used this PSU inside of a Lian Li PC-TU100b mini-ITX case and it fits great. The case is much smaller than many other mini-ITX cases so I felt that the cables were fairly long for what I needed but because the cables are flat compared to the sleeved, thicker, round cables found on most PSU's it was not an issue. I could simply snake the cables and use the same twist tie to essentially shorten them to my desired length. I appreciate the fan size of 120mm compared to smaller SFX PSU's which use the smaller 80mm fan. I cannot hear a thing from the PSU or the case for that matter. I would definitely recommend this PSU for anyone building a mini-ITX computer and maybe a microATX as well since there is a ATX mounting bracket included but you have to keep in mind what you're attempting to connect inside the PC that will need power from the PSU so you're not exceeding the connections available on this particular unit. Also keep in mind that you double check the available space you have when choosing a case so that this power supply will have enough space to fit and you do not run into clearance issues with either an aftermarket CPU cooler or anything else that might be a tight fit.
