Not fully compatible with ATX 3.1 standard. 12V rail transient response tests needs improvement. Trip thresholds (OCP) of the side rails must be adjusted. Mediocre transient response on the 3.3V rail. Hold-up time of the power OK signal is equal to the total hold-up time of the power supply. No protection mechanism in the event of a fan failure. Increased standby power consumption (Vampire Power). Distance between SATA connectors is less than 150mm. Conspicuous unclean soldering marks on the back of the PCB! |

Power supply does not meet any safety standards. For the main 12 Volt line there are only 168 watts. Workmanship of the power supply is even worse. Container of dirt in psu! |
