The CENTURY II 850W comes equipped with a 135mm fan (Model: HA13525M12F-Z), rated up to 1800 RPM. The fan is secured by a different set of screws. To open the entire PSU, you need to remove eight screws.


The CENTURY II is equipped with heatsinks to help with heat dissipation and features 100% Japanese capacitors, which we can verify here.


The PSU comes equipped with two Nippon Chemi-Con main capacitors – a 420V 470uF 105°C and a 420V 390uF 105°C aluminium electrolytic capacitors. It's quite surprising that this PSU packs two top-tier Japanese main capacitors, which suggests it’s a more premium build compared to PSUs with only a single main capacitor.


The secondary capacitors of the CENTURY II 850W are labelled “TK”, which is from the brand Toshin Kogyo – also a Japanese brand and is deemed a second-tier capacitor brand. Hence, the claim “100% Japanese capacitors” is true for this particular power supply unit from MONTECH.


For the MONTECH CENTURY II series, it appears that the 850W model uses a different PCB compared to the 1050W and 1200W models since this particular PCB only supports models up to 850W.
