Hot Test Results
As we'll see in the following tables, the FSP Aurum PT 1200W has good electrical performance. FSP claims that this unit's "E-Sync" technology improves the output power quality significantly; it does work, but it does not work wonders. Our instrumentation recorded a maximum ripple of 44mV on the 12V line, which is indeed a very good figure, though it's not extraordinary by today's standards. Similarly, the voltage ripple on the 3.3V and 5V lines is 20mV and 24mV, respectively. The voltage regulation is good as well, at 2.4% for the 12V line and under 2% for the 3.3V/5V lines.

High ambient temperatures have a substantial negative impact on the electrical performance of the Aurum PT 1200W unit. The average nominal load (20-100%) efficiency drops by 1.2%, while the maximum efficiency now is 93.0% at 50% load. Apparently, the Aurum PT 1200W unit does not like high ambient temperatures much.
Even at high temperatures, the FSP Aurum PT 1200W unit refuses to spin the cooling fan very fast. The results of this are obvious: very good acoustic performance at the cost of higher internal temperatures. The secondary side of the unit gets particularly hot, reaching up to 90°C at maximum load. This explains the significant efficiency drop, as the efficiency of these components is linked to their temperature. On the other hand, the Aurum PT maintains very low noise levels for a 1200W unit in a hot environment.

Starts at 30db? Not interested.kmmatney - Thursday, October 16, 2014 - link
"The unit is actually almost entirely silent up to 60% load, at which point the fan starts to speed up and becomes audible. "Death666Angel - Thursday, October 16, 2014 - link
Pretty sure they don't have a sound proof room to test, so 30dB is their noise floor.bsim500 - Saturday, October 18, 2014 - link
"Pretty sure they don't have a sound proof room to test, so 30dB is their noise floor."^ This. The only "quiet sound testing" which is useful these days is from SPCR (SilentPCReview) who built their own anechoic chamber with a single digit noise floor, and are very nitpickety over the quality of the sound too (clicking, buzzing, coil whine, turbulence, etc).

It seems a bit silly that they'd make the chassis look so nice only to slack off with the cables.. I expect that (but don't like seeing it..) in cheap units.. but not in higher end products that try to hit all the key points. FSP you can do better.wetwareinterface - Thursday, October 16, 2014 - link
this supply is a quality unit, gives 1200 watts, and is only $240. fancy cables means you up the price to $300 plus. and the market for sleeved cables is really small and served best by the custom choices out there.after you spend an extra $100 on sleeved cables you want them in a color to match your build not whatever color fsp decided to give everyone.

Simply using all-black wiring would be sufficient in most cases and not cost any extra. The multicoloured wiring doesn't look good in any build.just4U - Friday, October 17, 2014 - link

Take it from someone who works for a company that owns a large portion of the (braided) sleeving market. If you are charging your customers a markup for what amounts to $0.25 worth of sleeving...you are doing it wrong.just4U - Friday, October 17, 2014 - link
A lot of people who build computers want a nice clean uniform look to it all... it's not really even a plus anymore but rather a requirement. It doesn't necessarily add to the cost either and if it does it's certainly not by the amount your suggesting. That's not to say you can't spend that much with aftermarket items and/or certain themed products but it's not normally something that adds a ton to the overall pricing.
