PSU Roundup: Performance, Price, Efficiency
Cooler Master Silent Pro 500 Watt (Continued)
The cable management connector sockets are labeled, and they’re shaped so they can’t be plugged in incorrectly. The five-pin sockets are designed so that you can attach modular 4-pin Molex and SATA cables as needed. The 6-pin sockets are for auxiliary PCI Express graphics cables.
The power supply is cooled by a 140 mm fan on the underside. The warm air is exhausted through a breadboard on the back. The fan is controlled automatically by the power supply according to operating temperature—no need for manual adjustment.
The maximum power is, as advertised, 500 watts. The maximum combined load on the 5 V and 3.3 V rails is 145 watts.
This one seems to be more widely available in Europe—none of our favorite online vendors seem to be stocking it yet .

falchard 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.Reply
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. -
dirtmountain Nice fluff piece. I sure wouldn't use any of these recommendations over jonnygurus or hardwaresecrets sites though.Reply -
optik 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..Reply -
Proximon 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.Reply -
chookman Heat is generally relative to efficiency , due the fact that the more energy lost the more heat generated.Reply
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.

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