Our warranty does not cover the following:
- any product or serial number/warranty sticker modification applied without permission from NZXT;
- any damage that is not a manufacturing defect;
- damage, deterioration or malfunction resulting from: accident, abuse, misuse, neglect, fire, water, lightning, or other acts of nature, unauthorized product modification or failure to follow instructions included with the product;
- improper installation, unauthorized alterations or modifications, or repair or attempted repair by anyone not authorized by NZXT;
- shipping or transport damage (claims must be made with the carrier);
• normal wear and tear.
NZXT does not warrant that this product will meet your requirements. It is your responsibility to determine the suitability of this product for your purpose. For NZXT Store orders, we cover two way return shipping for all exchanges and returns. For all other authorized dealers, NZXT Support does not cover return shipping and only covers one way shipping from NZXT back to the end user for exchanges.

V. LIMITATIONS OF IMPLIED WARRANTYEST
Here are no other warranties, expressed or implied, including but not limited to those of merchantability or fitness for a particular purpose. The duration of implied warranties is limited to the warranty length specified in Paragraph I.
VI. TO OBTAIN TECHNICAL SUPPORT
If you have already referenced your product owner's manual and still need help, you may contact us by phone at +1 (800) 228-9395, by email at service@nzxt.com, or visit the NZXT Support site at nzxt.com/customer-support.
VII. HOW TO OBTAIN A WARRANTY SERVICE FROM NZXT
To receive a warranty service for your product when purchased directly from NZXT, you must submit a request via the NZXT Support site outlining the problem. If a technician deems the product defective or requiring testing, you will be required to provide a copy of your proof of purchase, which will enable you to submit a Return Merchandise Authorization "RMA" request.
Once approved, you'll receive an RMA number, upon which you will be asked to ship the defective item back to NZXT with the RMA number clearly marked or labelled on the package. NZXT recommends that appropriate measures are taken to safeguard the product from damage during shipping.
VIII. APPLICABLE LAW AND ADDITIONAL LEGAL RIGHTS FOR CONSUMERS
This warranty gives you specific legal rights. These conditions are governed and construed in accordance with the laws of California (with exception of its conflict of law provisions), and the application of the United Nations Convention of Contracts for the International Sale of Goods is expressly excluded. The non-exclusive jurisdiction of the courts of California is agreed, which means that you may bring a claim to enforce your consumer protection rights in connection with this Global Warranty in the country which you have your habitual residence where you may have additional rights. These rights may vary.
For original consumers who are covered by consumer protection laws or regulations in their country, state, or province of purchase or, if different, their country, state, or province of residence, the benefits conferred by this warranty are in addition to all rights and remedies conveyed by such consumer protection laws and regulations. To the extent that liability under such consumer laws can be limited, NZXT's liability is limited, and its sole option, to repair or replacement, either new or refurbished, with a similar function that is equal or greater in value depending on supply.
In the United Kingdom:
- For NZXT products sold to customers in the UK, during the expected lifespan of your product your legal rights entitle you to the following:
Up to 30 days: if your goods are faulty, then you can get an immediate refund.
Up to six months: if your goods can't be repaired or replaced, then you're entitled to a full refund, in most cases.
Up to six years: if your goods do not last a reasonable length of time you may be entitled to some money back. - If the person seeking to rely on the guarantee is not the original consumer, the NZXT Warranty will cover the product in relation to that person provided that they are able to provide proof of the transfer of the benefit of the guarantee from the original consumer.
- The implied warranties under the Consumer Rights Act 2015 says that your goods must be as described, fit for all purposes for which such goods are usually supplied, and of satisfactory quality.
In the EU:
- If you are a consumer and have your habitual residence in the EU, you additionally enjoy the protection afforded to you by provisions that cannot be derogated from by agreement by virtue of the law where you have your habitual residence.
IX. WARRANTY SERVICE FROM RESELLERS
In the event that a warranty service is sought, you must provide proof of purchase (store receipt or invoice) in order to receive the service and if deemed necessary, repair or replacement product.
