Hold Up Time
The hold-up time is longer than 17ms, and the power ok signal is accurate but lower than 16ms. The ATX v3.1 spec is looser in this section than the previous spec.
Inrush Current
The inrush currents are high. A larger (in resistance) NTC thermistor could lower them.
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.
Good day Aris,
Sorry to bother you, but I need some help choosing a PSU. After reviewing all the information on your website, I am still unsure which one to go for—the RM750x or the Power Zone 2 750W from Be Quiet!. My main concern is the PSU mounting in my PC case, which is side-mounted at the top corner. With the RM750x, the power cord connector placement means that if I face the fan inside the case, it could affect airflow. If I face the fan outside, the power cord would have to bend awkwardly.
On the other hand, the Power Zone 2 seems like it would fit better with the fan facing outside, avoiding the bent cable issue. Given these constraints, what would you suggest in this situation?
Thank you for your time and help.
The alternative could also be FSP Vita GM 750w but I am not sure which one would be better.
Aris Did all internal power supply components required for tearing down for a documentation or just some sample you did it for a tearing down, because some cybenetics doesn’t have internal info like a Bulk caps, MOSFET, IC, switcher, etc
If you ask whether all Cyben reports have part analysis, unfortunately, not for older samples. But for newer ones we try to have them on all.
