The Inter-Tech ASPOWER U1A-C20300-D computer power supply powers components in server and industrial builds, delivering a stable 300W output. Its 80 PLUS certification and high efficiency of up to 90% reduce both electricity consumption and residual heat, contributing to lower running costs. The power supply uses active PFC for efficient energy use and supports a wide input voltage range with automatic switching. Its compact form factor simplifies installation in space-constrained cases, where a 40mm fan maintains an optimal temperature.
When choosing a suitable PC power supply, the key parameter besides the form factor is its power output. This indicates the maximum number of watts the power supply can continuously deliver to the computer's components. It is a good idea to use an online calculator to work out the optimal power output based on your chosen components.
High efficiency, confirmed by the 80 PLUS certification, contributes to lower running costs. For long-term, reliable operation, a comprehensive set of five safety protections for demanding conditions is included, which covers overvoltage, overcurrent, overload, short circuit, and overheating. The mean time between failures is 100000 hours, confirming its durability.
A 40mm fan provides active cooling, maintaining optimal operating conditions. The power supply supports a wide input voltage range of 100–240V with automatic switching. Its design can handle a wide range of operating temperatures from 0 to 50°C, which is crucial for industrial deployment. The power supply offers a set of connectors for the motherboard (20+4pin), processor (4+4pin), two SATA devices, four Molex peripherals, and one Floppy drive.
The 80 Plus certification was created to objectively evaluate the efficiency of computer power supplies. This gives users a simple and clear way to compare different models. On the European market (where 230V is used), there are six levels of 80 Plus certification with set requirements for computer power supplies. Higher energy efficiency primarily means lower energy consumption.
