Hold Up Time
The hold-up time is increased, and the power ok signal is accurate.
Inrush Current
The inrush currents are higher than the average. Not sky-high though.
Leakage Current
Leakage current refers to the small amount of current that flows through an insulating material or a semiconductor device when it is ideally supposed to be non-conductive. It is typically seen in electronics, such as transistors, capacitors, and insulators, where the current leaks due to imperfections or unintended pathways, even when the device is “off.”
Leakage current in power circuits is an alternating current flowing through the earthing conductor caused mainly by the EMC filter’s Y capacitors (Cy). The more Y capacitors, the higher the leakage current can be!
The IEC 62368-1, which replaces the IEC 60950 OFF (Office Equipment) and IEC 60065 TRON (Electronics, entertainment), defines the limits for maximum leakage (touch) current.
- Normal Condition: Maximum touch current = 3.5 mA
- Single Fault Condition: Maximum touch current = 10 mA
The leakage current is low.
Timings
The PSU supports Alternative Low Power Modes.
Would you go for this one or the NZXT C1200 3.1?
Thank you so much for this! I’ve been waiting for this review forever haha. One question: for your note on the lack of protection feature “The matter that Montech needs to take into account is the unit’s protection features, where I noticed some unusual settings in the over current protection on the minor rails that need to be corrected accordingly.”, what type of users/use cases will need to pay attention to this and may potentially want to opt for a unit with better protection? Thanks.
I am afraid there is not much a user can do to avoid issues with not properly tuned protection features. There is no way to constantly monitor the PSU or avoid situations where a rail can be overloaded by a part malfunction, for instance. This is why I pay so much attention to protection features.
Thanks for the response. That is *slightly* concerning then haha. Would you have any insights regarding the Super Flower Leadex III 1000 Watt unit? It’s now this 1200W Montech unit for $130 or that 1000W Leadex III unit for $110 for me. $20 difference. Great deal on both. I know you did a review on the 1300W unit and that one also did not seem to have flying colors with it so I guess it’s time I pick my poison haha. Thanks.
Leadex units are made by SF itself, not from another OEM, so typically they are pretty good PSUs. About the protection features on this specific unit, not sure though until l check it.
Would you just err on the safe side and get a Corsair RM850x Shift then? It is also in the same price range for me. I was interested in these 1000W+ units because of their prices, but if neither the Montech Century II nor Super Flower Leadex III 1000W ATX 3.1 have solid protection features, I’d rather get a less wattage unit for better protection. I only have a 5070 Ti. Thanks.
Thank you for the reviews.
