Affiliate disclosure

As an Amazon Associate we earn from qualifying purchases.

Shop buttons open a search for a wattage class, such as an ATX 3.1 power supply of the size a calculator just produced. They do not point at a chosen model, and WattWise Tools does not display prices. A purchase is between you and the seller. When a Newegg link is an affiliate link, a qualifying purchase may also earn a commission, at no extra cost to you. The wattage result does not change because a link can earn a commission.

Accuracy and liability

Every result is an estimate for informational purposes only. It is not professional advice, electrical advice, or a promise that a power supply, a graphics card, a battery, or a cable will behave as labeled in your case. Hardware wattages on this site are the manufacturers' published limits, not a measurement of your sample.

Verify the parts you buy against the manufacturer's specifications and a qualified professional. Use the tools at your own risk. To the fullest extent the law allows, Wraith Labs Studios is not liable for hardware damage, data loss, fire, electrical issues, or financial loss from using the tools or from a purchase you make. The full limitation of liability, the warranty disclaimer, and the indemnification are in the terms of use.
