The PSU does not include a power cable, the contents of the white box beside the psu
are some screws and 2 velcro cable management wraps.

EMI/Transient Filter, No MOV
1 - Primary bridge rectifier
2 - PFC/PWM Combo
3 - Primary cap by Capxon
4 - 5VSB Controller IC

All chinese electrolytic capacitor, at this price point I doubt we will see a japanese caps here
Brown cap - by CD288
Green caps - by Chingx
Blue caps - by BH

1 - 12V Rectifier - This psu has 24 Amps on the 12V rail but this rectifier is rated for 30 Amps and there's 2 of
them in parallel for a total of 60 Amps, this parts is overspec for this rail.
2,3 - 5V and 3.3V Rectifier - This Rectifier is rated for 20A and the 5V, 3.3V rail is only rated at 15A so this part
is enough to handle the 15A for this rail.

The output of the PFC diode is filtered by the Capxon 150uf 400v 85°C capacitor
1 - PFC diode
2 - PFC transistor

Cable length

24pin cable length about 15.5in
4+4 cpu cable length about 18in
8pin pcie cable length about about 16in

All the cables are AWG 18.

According to ChugNorris the oem for this is Huntkey but my guess is Enhance Electronics.

Transient Filter - Yes
MOV - No
PFC/PWM Combo - CM6805
Protection IC - WT7502
Bridge rectifier - T6KB60 (6 Amps)
5VSB Controller IC - XY6112
PFC Transistor - SGF180N60W3
Primary switching transistors - 2 x CM15N50 - from what I could dig it is rated at 15 Amps
12V output rectifier - 2 x MBR3040PT Rated at 30 Amps - 60 Amps
5V output rectifier - MOSPEC S20C45 - 20 Amps
3.3V output rectifier - MOSPEC S20C45 - 20 Amps
Primary capacitor - Capxon 150uf 400v 85°C
Secondary capacitors - BH, CD288, ChengX ( all 105°C )
