When choosing a power supply, it is important to consider the wattage needed for your system. Make sure to select a power supply that can provide enough power for all your components, with some extra headroom for future upgrades. Additionally, look for a power supply from a reputable brand with good reviews to ensure reliability and efficiency. **

When choosing between a System or Pure Power power supply, it ultimately depends on your specific needs and preferences. A System power supply is designed to provide stable and reliable power for your system components, ensuring smooth operation and longevity. On the other hand, a Pure Power power supply focuses on delivering clean and efficient power with minimal noise and interference, which can be beneficial for high-performance systems or sensitive components. Consider your system requirements and budget to determine which type of power supply would be the best fit for your setup. **

A power supply of 5V800mA would require a power supply that can provide at least 5V and 800mA of current. It is important to ensure that the power supply can deliver the required voltage and current without exceeding the limits to prevent damage to the device. It is recommended to use a power supply that can provide slightly more current than the required 800mA to allow for any fluctuations in power consumption. **

The choice between power supply and motherboard depends on the specific issue you are experiencing. If your computer is not turning on at all, it could be a problem with the power supply. However, if your computer is turning on but not functioning properly, it could be a problem with the motherboard. It's important to troubleshoot and diagnose the issue carefully before deciding which component to replace. If you're unsure, it may be best to consult with a professional technician. **

The choice between a linear power supply and a switching power supply depends on the specific application and requirements. Linear power supplies are known for their low noise and high accuracy, making them suitable for applications that require precise voltage regulation and minimal electromagnetic interference. However, they are less efficient and generate more heat, which can be a concern in some applications. Switching power supplies, on the other hand, are more efficient and compact, making them suitable for applications where size and energy efficiency are important. They are also capable of handling a wider range of input voltages. However, they may introduce more noise and have lower output voltage accuracy compared to linear power supplies. Ultimately, the choice between the two depends on the specific needs of the application, such as size, efficiency, noise, and voltage regulation requirements. **

Without specific information about the power supply in question, it is difficult to determine if it provides insufficient power. Factors such as the wattage rating, efficiency, and age of the power supply can all impact its ability to deliver adequate power to the components in a system. It is recommended to check the power supply's specifications and compare them to the power requirements of the components in the system to determine if it is providing enough power. **

The quality of LC Power power supplies can vary depending on the specific model and individual experiences. Some users may have had positive experiences with LC Power power supplies, while others may have encountered issues such as reliability or performance issues. It is recommended to research and read reviews on specific models before making a purchasing decision to ensure that the power supply meets your needs and expectations. **
