Nice review, but since the PCP&C Silencer series of power supplies are sourced from Seasonic, wouldn't it have made more sense to compare this Silencer to one of Seasonic's higher wattage power supplies rather than a lower grade Antec ps? Granted, the Neo HE is another OEM-sourced Seasonic, but certainly not up to the build quality of a true Seasonic....just open up the two and compare caps, rectifiers, and such...all a bit cheaper in the Antec vs. the Seasonic.
Why not test the same grade of power supplies against each other, esp. since Seasonic is the OEM supplier to PCP&C for their Silencer line? Maybe a Seasonic S12-700 would have been a better candidate seeing as how it is closer in power to the Silencer and would represent something closer to it in build quality and power output and reserves?
Second, why do you not purchase a true power supply tester like a SunMoon tester? A SunMoon SM8800 power supply ATE (automated test equipment) is essentially a machine made specifically for the testing of ATX12V power supplies. It has a number of ATX-type power connectors in the front (24-pin, 8-pin, PCI-e, Molex, etc.) and it can put up to 10 different static loads on up to 10 different rails at a time.
Also, why no ripple testing under load? A simple USB Instruments Stingray DS1M12 would be an ideal piece of equipment to use. You would use the Stingray as a medium between the data being spit out by the SunMoon load tester's Waveform Monitor output and something like a laptop or another pc for recording of that data. Ripple is what you call the small fluctuations in voltage that happens every ms or so that may not affect performance, but may kill your components in time.
One more point....PCP&C really harps on the "Modular is bad" in their myth page. So I wonder why an online reseller of PCP&C power supplies converts those power supplies to modular and PCP&C still honors their warranty on the modularized converted power supplies.
Honestly, if modular was so bad, it seems to me that PCP&C would instantly void their warranty status on any of their power supplies that were converted to being modular, considering their stated stance on the subject. Yet Performance PC's does just that and PCP&C honors their full 5-yr. warranty on Turbo Cool ps's with the modular conversion done to them.
