    5Good Alternative to ST45SF-G If You Want Soft Cables and Less Noise
    By znd125
    This PSU worked exactly as I expected. Quiet (if not silent), flexible cables, well made.

    I have this PSU in a Lian Li PC-TU100B, which previously housed the Silverstone ST45SF-G. My issue with that PSU is exactly what Silverstone describes in the "Product Description" of SX500-LG - the high-pitched noise. It was not loud, but was very noticeable and thus extremely annoying. The SX500-LG addresses that exact problem with a larger fan and a less aggressive fan curve.

    Before purchase you need to make sure that it fits in your case because the SX500-LG is longer than a standard SFX PSU.

    Other features that I like:
    - Flexible cables, similar to the PP05-E set
    - Native support for dual 6+2 pin PCIe power connectors
    - The ATX bracket included has a better build quality

    5Best for a SFF build right now.
    By Scott Byer
    I saw the SG05 at Fry's Electronics in Atlanta several years ago, and I have always said to myself "I should get it some day for a low-power Linux box or HTPC." We'll, after seeing the Bitfenix Prodigy come out, it got me thinking about a mini-ITX build. I started looking at everything mini-ITX that is out now, and it looks like things have gotten much better. Instead of this low-power Linux box, I could house some actual parts and replace my Corsair 650D with something smaller since I just need one PCI-E slot.

    That being said, I turned to this PSU because it was the only one that was modular, 80 Plus Gold, and enough wattage (Coming from an AX750 in my Corsair 650D, I didn't want to compromise).
    I was worried that Amazon would ship me one of the older v1.0 units and I'd get the annoying fan noise. However, I ordered mine on 10/20/2013, and I got the v2.0. This made me happy to know I got the most recent and silent one. I probably would have returned a v1.0 had Amazon sent me one.

    This thing is dead silent. My Corsair H50 pump drowns out the noise of the fan. I can only hear it if I put my ear right up to the back of the PSU. People will say "you'll use all the cables anyway, so get the non-modular, hur hur hur!!!" However, if you're really into this stuff, you'll get the 80 Plus GOLD and Silverstone's short cable kit (P/N: PP05) and shorten and cut the cables yourself to save space. That way, if you screw it up, you can just replace the cables. Plus, I've avoided using one of the cables, so I don't have to tuck cables anywhere.

    I bought it for those two reasons over the non-modular. That, and it was just as expensive as getting the SG05 + non-modular PSU together. Instead, I got the SG05 Lite and this PSU.

    One negative is that the cables aren't all that flexible, but I'm in the process of cutting them down to fit anyway. Another negative is that it's difficult to use the 3.5" bay in the SG05 with the modular cables because of the connectors sticking out the front butt up against the drive cage. I remedied that by getting rid of the drive cage and using a 2.5" drive for storage at the bottom.
    However, it IS possible to use the 3.5"/2.5" ODD cage WITH this PSU. You just have to install your drives first and then the PSU by feeding your cables into the case (not connecting them yet) and then tilting it to meet the bracket at the back, and then slowly tilting horizontally into position with the cables making a sharp downward turn.

    UPDATE:
    It's 8/3/14, and I've been using the PSU for almost a year. NO issues whatsoever. It's powering an Asus Z87i-Deluxe, i5-4670k (overclocked to 4.2Ghz), 240GB SSD, 1TB notebook hard drive, Corsair H55, and GTX670 Mini.

    1Avoid this PSU. Failed at 7 months mark.
    By Jon
    Pros:
    - Worked fine for the past 6-7 months.
    - Cannot simply find many gold rated SFX PSUs that output 600W.
    - Includes ATX bracket making it compatible with non-ITX cases.
    - It's small, which makes cable management a bit easier in cases like the Cougar QBX. The QBX supports ATX sized PSUs, so building with this PSU will free up some space for cable management.

    Cons:
    - PC started shutting down when under load after 7 month mark. At first I thought my temperatures were triggering a safety shutdown, so I changed cases and switched to a closed loop for my CPU (i7 6700, no overclock), but the shut downs continued. Then I had the idea to run Prime95, then Furmark, then both together to see if I could trigger a shutdown on my own. Found that with 100% certainty running both stress tests would trigger the shutdown within a minute of starting the test. I now zeroed in on the SX600-G, so I switched to a Seasonic SSR-650RM and ran the same torture and stress tests; not a SINGLE shutdown.
    - The cables are too short to reach components in the Phanteks Evolv Enthoo ITX. If you plan on using this on larger ITX or mATX cases, make sure you pack some extension cables.

    Other Thoughts:
    - If you read JonnyGuru and Hard OCP's review of this unit, you'll find that Silverstone skimped heavily on the capacitors for this unit, which is unforgivable for a unit of this caliber and price.
    - Troubleshooting PSU problems can be a real pain unless you have the tools and know-how.
    - There's a reason why this unit is scoring consistently mixed/low reviews on Newegg. Avoid it.
