Features and Benefits
Power output and Efficiency
The Power output of the 405349-001 HP 575-Watts Desktop Power Supply XW6400/XW8400 refers to the maximum amount of electrical energy that it can produce. In this case, the power output is 575 watts, meaning that the power supply is capable of providing a maximum of 575 watts of electrical energy to the components within the computer.
The efficiency of a power supply refers to how effectively it converts the electrical energy it receives (from an outlet or other source) into the energy that is used by the computer's components. The efficiency of the 405349-001 HP 575-Watts Desktop Power Supply XW6400/XW8400 is not specified by the manufacturer, but it is typically around 80-85%. This means that around 80-85% of the electrical energy received by the power supply is converted into usable energy for the computer, while the remaining 15-20% is lost as heat.
Maintenance and Troubleshooting
Maintenance and troubleshooting of the 405349-001 HP 575-Watts Desktop Power Supply XW6400/ XW8400 involves several steps:
- Check the power cord and outlets: Ensure that the power cord is plugged in properly and that the outlet is functioning properly.
- Check the internal connections: Open the computer case and check all internal connections to ensure they are securely plugged in and properly connected.
- Check the power supply: Ensure that the power supply is securely plugged into the motherboard and that all connections are properly connected.
- Check the voltage: Use a multimeter to check the voltage output of the power supply. The voltage should be within the specified range as listed in the user manual.
- Check the fans: Ensure that the fans in the power supply are functioning properly and that there is no dust accumulation.
- Replace the power supply: If all of the above steps have been checked and the issue still persists, it may be necessary to replace the power supply.
Troubleshooting:
- No power: If there is no power to the computer, check the power cord and outlets as well as the internal connections.
- Random shut offs: If the computer randomly shuts off, check the voltage output of the power supply. If it is outside the specified range, replace the power supply.
- Overheating: If the power supply is overheating, check the fans and clean out any dust accumulation.
- Short circuit: If there is a short circuit, check all internal connections and replace any damaged components.
It is important to note that if the power supply is not functioning properly, it can cause damage to other components in the computer. It is best to seek professional help when troubleshooting and maintaining the power supply.

About Refurbished Products
Every electronic device has a PSU that converts AC voltages from the mains supply to different DC voltage levels required by the components and systems. It is not a different story for computers, servers, workstations, and any other IT equipment in your server. Most of the computer power supplies we see today use switched-mode operation and conforms to the ATX standards.
How to Choose a Desktop Power Supply
Different manufacturers have varying designs for their products. That has led to the differences in the desktop power supplies in the market today. Some of the parameters are efficiency, form factor, protection, input and output power rating, and many others. When searching for a new desktop power supply, you have to factor in these parameters:
Desktop Power Supply Efficiency
You need a desktop power supply with the highest efficiency, there is no doubt about that. The efficiency of these power devices is defined as the ratio of output to input power. An efficient PSU produces less heat, making the cooling of the system easy. A less efficient product, on the other hand, leads to wastage of electrical power.
Protection
You don't want your newly acquired product to smoke just a few months after buying it. The system also needs protection from voltage and current spikes, and overload. Ensure your new product is safe for use, even when there are power surges.
Power Rating
The total output power from a PSU matters a lot, and it depends on the intended use. Different PSUs in the market have varied ratings. For that reason, you have to be very careful not to buy inappropriate PSU. For example, an HP switching power supply for DC7100 is rated 340W while a 3YKG5 Dell power supply for Dell Optiplex is rated 240W. This shows that you need to define the targeted use of the power supply before making the purchase. Also, check the rated input and output parameters and your power system frequency.
Power Supply Form Factor
You have many options when it comes to the chassis size of the Desktop Power Supply unit. Firstly, you need what will easily fit in your existing case. Secondly, you need to check whether it is modular or not. Most of the power supplies you will find use ATX standards to define the physical size. There are desktop power supplies with small form factors such as SFX and CFX. For example, 468929-003 HP is an SFF power supply unit.
Power Supply Connectors
If the connectors in your desktop power supply cannot match the component pins on the computer, then that PSU is not useful. You have to match the power connectors on the PSU to the pins on the motherboard.
Power Factor Correction
Some power supply units, such as Lenovo 240W, have a power factor correction mechanism. This is to avoid back-feeding harmonics to the power system and comply with the laws in some regions. A power supply with PFC mechanisms is also more efficient than those without. If the power factor is your main concern, then you can check out this feature.
