Hello Folks! Welcome to Our Blog.

Wattage Calculator There are different categories to consider when choosing a generator for your needs: recreation, home standby and construction. You may also want to consider using an inverter generator for sensitive electronic devices. Inverter generators are smaller and lighter as power is created electronically and not through a conventional alternator. Inverter power offers the cleanest power output. This is important depending on what items you want to run off of your generator.

Items such as toaster, lamps, and coffee makers are resistiveor constant loads and their total load can be calculated at amps x 1. Items such as saws and drills are reactive loads and while the running load may be small, the starting load should be calculated at running amps x 3. Remember, after the intial start less power is required for actual operation.

Always remember that simple power management will allow a smaller generator to do a big job. Very seldom are all tools or appliances operating simultaneously. When calculating power requirements, consider the starting requirements are only for the initial start and then additional tools may be operated in addition.

A maximum starting watt value is generally 5 times running watts. However, some new air conditioner brands have realized more home standby plants are being purchased every year. A re-design in air conditioner starting loads, has begun, to lower this huge starting demand.

If it's important to you, to have air conditioning during utility power blackout, consult licensed electrician to check locked rotor starting amps, to ensure air conditioner will start, while other loads are already in use.

A maximum starting watt value is generally 3 times running watts. PAGE 2.

The best power supply for your PC build is the one that provides the right amount of wattage to all components simultaneously.

Manually calculating this requires that you multiply the total amps of all components by the total volts of all components. The result is the total watts that your PC build requires. If you input all the components of your PC build into our calculator, it will do this for you and provide a list of options.

The power supply provides power to every component and if you install the wrong power supply, you could damage the components. The right PSU will provide all your components with a consistent amount of energy when they need it. Every PC case has a space for the power supply unit although the space may vary in size and shape. For example, small form factor cases will not be able to accommodate a PSU meant for a mid or full tower case.

It is always best to look at the dimensions of your PC case and make sure that you are buying a power supply unit that can fit in the designated space. Newegg Insider is a great place to get information about the latest and greatest in tech.

What are some of the top PSU brands that I can buy? How do I know that the PSU is the right size? Where can I get news about power supplies? How do I know which power supply to buy? Motherboard — Be sure you know what kind of motherboard Desktop, Server, Laptop, etc.

This is a critical component of your calculations because almost everything within your build plugs into and derives power from the motherboard. So make sure your PSU has enough cable to support that. Most PSUs will have at least one cable that is compatible with either an 8-pin or a 6-pin connector.
