Silverstone SST-ST70F Strider 700W

Silverstone sent its 700-watt SST-ST70F Strider to our test course. Although the power supply arrived in fairly unassuming packaging, the unit itself features good cable management system and plenty of cables for attaching peripherals.

The power supply comes with all its lines plugged in by default. The SST-ST70F is the only modular power supply in the test field where you can literally remove the lines—including the processor power supply and the ATX cable.

The removable nature of the ATX cable doesn’t make sense because you can’t run a power supply without its ATX line, but it lets you get the stiff ATX cable out of the way when you want to remove other components from the small device.

    That coolermaster PSU is nice that its cables are thin since its really annoying to have those stiff cables fill a small case. However, I wonder about its interference. That insulation and mesh is there for a reason, to prevent discharge and electrical interference of other parts.

    Also I can see the reason why a person wouldn't want a CPU/ATX connector on a 700w power supply. If they had an excessively power draining system like a Quad/Tri GPU with modern high end cards it will waste alot of power and using 2 lower watt power supplies is cheaper then getting 1 high watt one.

    Nice fluff piece. I sure wouldn't use any of these recommendations over jonnygurus or hardwaresecrets sites though.

    Just bought myself Zalman's ZM-750HP with cable management and heatpipe cooling.. Cost only 131 euros.. When I saw the article's header I hoped to see it being reviewed, but no such luck. Would've been nice to see how the Zalman's offerings would've fared against others.. The productline ranges from 360Watts to full 1000Watt PSU's so plenty to choose from..

    Without voltage ripple and heat tests you can't properly evaluate a power supply. At least readers can use this as a starting point for further research.

    Heat is generally relative to efficiency , due the fact that the more energy lost the more heat generated.

    Ill agree with the ripple tests too, yeh great we might have a power supply that is efficient at 100% but what if the 12v rails are hovering outside of spec...? Its a nothing review really.

    What manufacturers use insulation and mesh that block interference? The insulation on the wires of my PSUs is standard insulation, the mesh is plastic and there strictly to hold the wires in place and prevent the inside of a computer case from becoming a birds nest of wires.

    If there are manufacturers that use materials to block interferences, I'd like like to look into their products as it sounds interesting but I'd like to hear from someone actually in the know as to if it would make any difference or not.

    Interference on a power supply is negligible. The power runs, voltages and current are of little concern for interference. IF you want to be truly theoretical it would make a "difference".

    When I studied power engineering one would need a ton of voltage or current to be 'eligible' for most electrical phenomena to occur - theoretically.
