Share with you guys some reviews from coolaler for Germany Bequiet

The model that I reviewed is 450W. Before unpacking, it looks like so, whole color box is covered by the heat-sensitive film as usual.

The fan used is a FDB fan, MGA12012LF-A25 from Protechnic. With the temperature control design of the PSU, the quietness is guaranteed.


Let’s have a look from above (fan removed)


First, here is the major capacitor in the primary side. It’s a HITACHI capacitor from HP3 series, 85 Celsius 330uF


The auxiliary side uses a 16V 2200uF 105 Celsius capacitor from KY series, Japanese NCC


The secondary side uses a 16V 1000uF 105 Celsius electrolyte capacitor from KY series, Japanese NCC.


The other capacitors are the 105 Celsius electrolyte capacitors from YXA series, Japanese Rubycon


The monitor IC is PS229 from SITI. The 6P protection relies on it.


Test Platform Config.
CASE：CoolerMaster Cosmos RC-1000
CPU：INTEL Xeon X3360
MEM：DDR2 800 AA3G 2GB x 4 (4.99GB of it is for RAMDISK)
MB：Gigabyte GA-EP45-UD3P
VGA：MSI ATI Radeon HD 2600 XT 256MB Silent Version
COOLER：THERMALRIGHT Ultra-120 Extreme(with TT smart case fan II )
HD： WD 3000HLFS 300G (Sys HDD)
Hitachi HDT721010SLA 1TB
WD 6400AAKS 640GB
WD WD3200AAKS 320GB


In order to increase the test accuracy, all 4 HDD were applied.


Let’s start the PC. Through the BIOS, the voltage, 12V and 3.3V, are both correctly detected.

Last, I tested the voltage fluctuation by running 3dmark06. Because Everest couldn’t detect 5V value, therefore
I replaced it with 5V standby.

Before test:
(in order to get a more accurate test result, I made it to record the wave movement one time every second)


Test Result: very smooth
