Hold Up Time
The hold-up time is lower than 17 ms. At least, the power OK signal is accurate but short.
Inrush Current
The inrush currents are so low that I couldn’t get a meaningful reading. This is good!
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, indicating that the transient filter’s Y caps have low capacity. The capacitance value of Y-capacitors influences leakage current; a larger capacitance value leads to higher leakage. The lower capacity doesn’t help, though, in restricting the conducted EMI emissions.
Timings
The PSU supports Alternative Low Power Modes.
Yello, I’m in India and only have two same priced PSU options: MSI MAG A750GL and Deepcool PN750M, everything else is priced at 1.5 to 2 times these psu. They are almost identical units, but I’m still confused which to get. Which would you suggest?
THANKS! 😁
MSI
Hi Aris, quick clarification, when I asked about the MSI A750GL vs PN750M (under the GLS review), did you mean the GL or the GLS model in your reply? I only have the GL variant available.
The one you had in your answer.
