Welcome to the free UPS sizing calculator. To simplify UPS purchasing for our customers, we have built this free tool designed to easily determine the electrical load of your equipment, and the minimum recommended UPS VA rating for your needs based on your desired run time.

It's easy to use - simply select the type of equipment you are looking to protect, either from our list of generic equipment, or by HP, Cisco, or Dell part numbers. Add a line for each device that you are looking to protect, and then press the 'calculate your requirements' button to see what size UPS you should consider. if you would like one of our power protection experts to prepare a quote for a suitable solution, please use our live chat, email us at or call us at (845) 357-6911.

Note: There is a limit of five (5) devices per category, i.e (5) generic devices, (5) Cisco devices, etc.
