Terms of use
These terms cover WattWise Tools, operated by Wraith Labs Studios. By using the site you accept them. If you do not accept them, do not use the site.
Use at your own risk
Results are estimates for informational purposes only. They are not professional advice, electrical advice, engineering advice, or a recommendation to buy a particular product. Always verify the parts you intend to buy against the manufacturer's specifications, the power supply's own manual, and a qualified professional. You are responsible for the build, the wiring, and any purchase you make.
Power supplies, graphics cards, batteries, and cables can fail, overheat, or fall short of a label. A number on this site is not a measurement of your PC and not a sign-off that a build is safe.
The service
The calculators run in your browser. Wraith Labs Studios may change, suspend, or remove any page or tool at any time. Access is offered as available, and it may be interrupted by the host, by maintenance, or by a change to the site.
No warranties
The site is provided AS IS and AS AVAILABLE, without warranties of any kind, whether express or implied. That includes warranties of accuracy, merchantability, fitness for a particular purpose, title, and non-infringement, and any warranty that the site will be uninterrupted, timely, or error-free. Some jurisdictions do not allow certain warranty disclaimers, so those limits apply to the extent the law allows.
Limitation of liability
To the fullest extent the law allows, Wraith Labs Studios is not liable for any loss or damage arising out of your use of the tools, your reliance on a result, or a purchase you make after using the site. That includes hardware damage, data loss, fire, electrical issues, personal injury, and financial loss, and it includes direct, indirect, incidental, special, consequential, exemplary, and punitive damages, whether or not Wraith Labs Studios was advised they were possible. If a jurisdiction does not allow a limit of this kind, the limit applies to the fullest extent still allowed. The disclaimer is part of this allocation of risk.
Indemnification
You will indemnify and hold harmless Wraith Labs Studios from claims, damages, losses, and reasonable expenses, including attorneys' fees, arising out of your use of the site, your build, your reliance on a result, or your breach of these terms. Wraith Labs Studios may control the defense of a claim that this section covers, and you will cooperate in that defense.
Third-party links and affiliate products
The site links to manufacturers, Amazon, Newegg, and other sites Wraith Labs Studios does not operate. Those sites have their own terms and privacy practices. A purchase is a transaction between you and the seller. An affiliate relationship, described on the disclaimer, does not change the wattage math and does not mean Wraith Labs Studios endorses a particular unit.
Intellectual property
The text, design, and code of WattWise Tools, and the WattWise Tools name, are reserved by Wraith Labs Studios. You may not copy the product and present it as your own. Linking to a page is fine. Manufacturer specifications remain the property of those manufacturers and are cited as reference.
Changes
Wraith Labs Studios may update these terms by posting a revised version on this page and changing the date above. Continued use of the site after that posting is acceptance of the revised terms.
Governing law
These terms are governed by the laws of the United States and the state in which Wraith Labs Studios is based, without regard to conflict-of-law rules.
Severability
If a provision of these terms is held unenforceable, the remaining provisions stay in effect. The unenforceable provision is modified to the minimum extent needed to make it enforceable, or severed if it cannot be modified.
