Packaging and Appearance





The box comes in traditional dark colors. Inside you will find the PSU, a rubber connector, screws and cable-ties. The power supply itself is coated in a soft black matte like all power supplies from Silverstone. The 12cm fan is located in the middle of the upper side and is secured with a black fan-guard. This PSU is an all-rounder which means it can be connected to any AC output from 100 up to 240Vac. This is already standard for most manufacturers and for Silverstone it seems to be so much of a standard that they even didn't mention it anywhere on the package.







The back of the power supply, which is located inside of the PC when installed, is totally closed except for the small opening in the lower-left side. This is to provide a little extra ventilation to cool the coil sitting directly behind it.

    That makes sense, and makes me think my guess about the 20A limit is possibly a contributing factor - It would be a safety issue if someone hung 40A worth of fans, lights, motorized case windows, whatever you want.. off of one pair of wires (IE, one molex connector feeding into the mass of extenders and passthrough connectors that most fans and lights I've seen use.).

    You'd likely overheat the wires carrying all that power, if not the connectors as well, which could cause fire or electrocution hazards.

    While a GPU may draw significantly more than 20A, they are also using 3 pairs now, so the actual power draw will be closer to 20A per pair.

    The PCIe V2.0 PSUs I've seen suggest only using connectors from the same 12V rail for PCIe graphics cards -- because if you don't, you'll be connecting the common from two different 12V rails together.

    This can cause issues.

    If a graphics card has one 4pin and 1 8pin connector, like the HD 2900 XT, the GPU can potentially draw up to 225W from a single 12V rail through 2x PCIe graphics power connectors (3 pairs). That's about 19 amps through one rail for one PSU, but not over each pair.

    They explained it.
    The Intel ATX standard calls for no more than 20 Amps per 12V rail. So in order to avoid maxing out a single 12V rail at 20 Amps, PSUs have multiple rails support up to 20 Amps each.

    If you use a single rail that can max out at 54 Amps as stated here, then you do not need the additional rails, but you are going against the ATX standard.

    Also, I didn't see if there was a reason that it was advertised as a single rail, yet you have 4 12V rails.

    Nice article...really love the line curves for the load outputs. One thing I noticed missing is ripple testing. Any reason why it's not here?

    That confused me as well. I think they mentioned that the PSU supposedly includes an ability to turn the other rails off, but it doesn't work, and it always has 4. They did state the PCB was originally designed for 4 rails. Reply

    Nevermind...disregard my statement about the ripple testing. I probably just missed it in the original article after skimming the comments from it :) Reply
