About New Bulk Pack 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.
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.
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 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.
