THE ST1500-GS INTERIOR
The 135mm dual ball bearing fan used is manufactured by Young Lin Technology and can spin up to 2500RPM (±10%) to produce airflow of up to 123.64CFM with up to 51.92dB of noise.
As you can all see there are two large heatsinks inside the housing (Enhance Electronics is behind the ST1500-GS).
On the primary side we see four Panasonic electrolytic capacitors rated for 270 uF, 420V, and 105°C.
Secondary capacitors are manufactured by United Chemi-Con and are rated for 2200 uF, 16V and 105°C.
