A Closer Look – Interior
The Be Quiet Power Zone 1000W power supply is manufactured by FSP, one of Be Quiet’s most preferred OEM partners. The design makes use of a Active Clamp Reset Forward (ACRF) topology for the primary side and synchronous DC to DC converters for generating the minor rails. Despite it’s modest 80 Plus Bronze certification this platform is used by a handful of 80 Plus Gold rated units so we’re expecting Gold performance from it.
The provided fan is far from quiet with an operational speed of up to 2900 RPM. We are not sure why this is so aggressive given the high efficiency of the unit.
The input pathway features a single X cap and pair of Y caps for filtering with additional components on the PCB that include: two CM chokes, one X cap, two Y caps and an MOV.
The two primary hold up capacitors offer 450V, 270uF and up to 105 degrees celsius operation, these are manufactured by Teapos.
All the used electrolytic capacitors are manufactured by Teapo and are rated for 105 degrees celsius operation – this means they are of high quality.
