2 x 500W Silverstone Gemini Redundant, Hot Swap, 80PLUS Silver, PSU is rated 5.0 out of 5 by 1.
Rated 5 out of 5 by from Impressed I found getting hold of a redundant power supply which I could put into a fairly regular PC chassis quite difficult until I stumbled across this. The power supply is quite pricy, but when its loaded into your PC its fairly evident that its definitely more of a professional bit of kit than consumer. The power output seems very good, lots of PSU manufactures rate their power supplies on the absolute maximum they can output, not the amount that they can output comfortably, and many people building their own computers (most specifically gamers) often vastly over specific their power supply requirements. This 500w x2 unit is quite comfortably powering up 2x 8 Core Xeons, 8x 4TB discs and 32GB of registered RAM, even when only a single module is plugged in. Comes with two very chunky IEC cables to get you going as well as some velcro cable ties and screws to mount this into your chassis. Bear in the mind though that this isn't a standard 'ATX' fit, although its a very similar size, the screw holes won't match up, you might need to contact your case manufacturer and ask if they can provide you with a 'PS/2 mini redundant' adapter plate. The power supply its self is fairly noisy, although not ridiculous. This is due to the four 40mm fans between the two power supply modules. I'm sure dismantling the unit and replacing the stock fans with more expensive ones would fix this problem (although it will void your warranty so you do it at your own risk), but this is designed more for 24/7 operation than to sit under your desk at home with a very high MTBF so if its going to live in a server room then your probably not too concerned about that. Its got a fairly standard loom of outputs, including a single PCI-E connector, and single 8pin EPS connector for the CPU (my motherboard required two, which was easily sorted with a cheap molex to 8pin EPS adapter), upon removing one of the power cables whilst the PC is powered up, the PSU will beep loudly to alert you that its lost one of its inputs, and you can press the button on the back to silence it, it also has a small LED on the end of a cable you could poke through you chassis somewhere so you can see visually of any errors also. Overall very impressed, just make sure you get hold of the correct adapter if you want to put this in a standard case!
