Mouse & Key Gaming PC Giveaway 2026 – Win an RTX 5080 Build

The Mouse & Key Gaming PC Giveaway 2026, officially called Sweepstakes #4, gives eligible participants an opportunity to win a custom-built gaming desktop with an approximate retail value of $4,300 USD.

The advertised computer features an AMD Ryzen 7 9800X3D processor, GIGABYTE AORUS GeForce RTX 5080 16GB graphics card, 32GB G.Skill RAM, 2TB KLEVV SSD, and Lian Li O11 Vision Compact chassis. One winner will receive the gaming PC described in the official rules.

The promotion is organized by Lamily LLC, doing business as Mouse & Key. It runs from October 17 through November 16, 2026, with a random winner drawing scheduled for approximately November 25.

The complete rules permit eligible adults residing in the United States, Washington, D.C., and Canada, although the organizer's abbreviated website footer lists only U.S. residents. This discrepancy requires clarification.

Participants can obtain entries through qualifying purchases or memberships. A free alternative is available by mailing a handwritten entry to the sponsor. Each valid postal submission provides 100 entries, with a possible 500-entry allocation during an eligible bonus period.

Mail-in entries must be postmarked by November 16 and received by November 23, 2026. All participants should review the full official rules before entering.

Paid methods: Qualifying merchandise purchases, eligible digital product purchases, or paid membership transactions can automatically generate entries according to the organizer's disclosed amounts.

Free entry method: Handwrite your full legal name, complete address, phone number, date of birth, and email address on a 3×5-inch card or paper. Mail it individually in a standard #10 envelope with proper first-class postage to:

The Mouse & Key Sweepstakes #4 official rules allow legal residents of the 50 United States, Washington, D.C., and Canada who are 18 or the age of majority in their jurisdiction, whichever is older. Puerto Rico and other U.S. territories are excluded. Employees and specified related persons cannot enter. A restriction for New York and Florida applies only to editions whose announced prize value exceeds $5,000; this edition's value is $4,300. Canadian potential winners must correctly answer a mathematical skill-testing question before being confirmed. No purchase is necessary because an alternative mail-in method exists. Important: the website's abbreviated footer describes U.S.-only eligibility, contradicting the full rules' inclusion of Canada. Canadian eligibility should be confirmed with the sponsor before publication.

The Mouse & Key Gaming PC Giveaway 2026 offers eligible gamers a chance to win a custom-built desktop PC featuring an NVIDIA GeForce RTX 5080 graphics card and AMD Ryzen 7 9800X3D processor. Known officially as Mouse & Key Sweepstakes #4, the promotion is organized by Lamily LLC, doing business as Mouse & Key, and advertises one gaming computer prize with an approximate retail value of $4,300 USD.

The giveaway opened on October 17, 2026, and closes on November 16, 2026, at 11:59:59 PM Eastern Time. The complete official rules include eligible residents of the United States and Canada, although the website's abbreviated footer mentions only the United States. Entrants should confirm their eligibility with the organizer if this discrepancy affects them.

Mouse & Key offers several ways to obtain entries through merchandise purchases, digital products, and memberships. Importantly, a purchase is not required: the official rules provide a separate mail-in entry method that allows eligible participants to enter without buying products or memberships.

What Can You Win in the Mouse & Key Gaming PC Giveaway?

One eligible winner will receive a custom gaming desktop built with components identified in the organizer's official rules. The approximate retail value of the complete announced prize is $4,300 USD.

Custom RTX 5080 Gaming PC Specifications

• Processor: AMD Ryzen 7 9800X3D.
• Graphics Card: GIGABYTE AORUS GeForce RTX 5080 with 16GB GDDR7 memory.
• Memory: G.Skill Ripjaws M5 Neo RGB Series 32GB RAM.

• Power Supply: Lian Li EDGE GOLD 1000W 80 Plus Gold.
• PC Case: Lian Li O11 Vision Compact.

• CPU Cooling: Lian Li Galahad II Trinity Performance 360mm.

The combination of an RTX 5080 graphics card, Ryzen X3D processor, 32GB memory, and 2TB storage is intended for demanding PC gaming and other hardware-intensive activities. The cooling system and 1000W power supply are also included in the listed build.

The official rules identify one gaming computer as the prize and do not include a separate cash component. Some images and specifications displayed elsewhere on the organizer's website may relate to different or earlier builds, so the written Sweepstakes #4 rules should be used to identify the advertised prize.

Who Is Eligible to Enter?

According to the complete Sweepstakes #4 official rules, participation is available to legal residents of the 50 United States, Washington, D.C., and Canada who are at least 18 years old or have reached the age of majority in their jurisdiction, whichever is older.

Puerto Rico and other U.S. territories are excluded. The rules contain a special condition excluding residents of New York and Florida when a particular sweepstakes has an announced prize value exceeding $5,000. The current announced prize value is $4,300, so that particular threshold does not apply to this edition.

Employees, specified business affiliates, their immediate family members, and certain household members cannot participate. The promotion is not a worldwide giveaway.

Because the organizer's abbreviated website footer lists U.S. residency only, Canadian entrants should verify the broader eligibility stated in the complete rules before submitting an entry.

How to Enter the Mouse & Key Gaming PC Sweepstakes

The organizer provides four entry routes. Three involve qualifying paid transactions, while the fourth permits participation without purchasing anything from Mouse & Key.

Method 1: Qualifying Merchandise Purchases

1. Visit the official Mouse & Key giveaway page.
2. Review the current sweepstakes rules and eligible products.
3. Purchase qualifying merchandise from the organizer's online store if you choose this method.
4. Receive the applicable automatic entries associated with the completed transaction.

Under the official rules, qualifying merchandise purchases generate one entry for each whole U.S. dollar of eligible spending before taxes and excluding shipping and handling. Applicable discounts reduce the qualifying purchase amount.

Method 2: Digital Product Purchases

Eligible digital products may award a specified number of entries. The applicable entry quantity must be disclosed on the product page and before checkout. Different digital products can award different entry amounts.

Method 3: Paid Membership Entries

Mouse & Key also offers memberships that can award entries when an eligible initial or recurring payment is successfully processed. The specific number of entries depends on the membership tier and the conditions shown during enrollment or renewal.

Canceling a membership prevents future renewal charges and future associated entry awards. Previously awarded entries from completed, nonrefunded membership transactions remain subject to the official rules.

Method 4: Free Mail-In Entry — No Purchase Necessary

Eligible participants who do not wish to purchase merchandise, digital products, or memberships can use the official alternative method of entry (AMOE).

1. Prepare a 3-by-5-inch card or piece of paper.
2. Handwrite your full legal name, complete mailing address, telephone number, date of birth, and email address.
3. Place the handwritten entry in a standard business-size #10 envelope.
4. Affix the appropriate first-class postage.
5. Address the envelope to:

Mouse & Key Sweepstakes #4
1457 Kelly Rd #470
Apex, NC 27502
USA

Each valid mail-in submission receives 100 sweepstakes entries. If a qualifying bonus-entry period is announced, a properly submitted entry postmarked during that period can receive 500 entries, subject to the applicable conditions.

To claim the bonus amount during an eligible period, participants must write the applicable bonus multiplier in the bottom-left corner of the envelope. An incorrect or inapplicable multiplier will result in the standard mail-in entry value.

All cards and envelopes must be handwritten by the entrant. Mail each envelope individually; bulk submissions, automated entries, and third-party entry services are not permitted. Each mailed submission must be postmarked by November 16, 2026, and received by November 23, 2026.

No purchase from the organizer is necessary, although participants using the postal method are responsible for postage and mailing materials. The official rules do not establish a general unlimited-entry allowance.

How Will the Winner Be Selected?

The sponsor will conduct a random drawing from eligible entries. One potential winner is expected to be selected on or about November 25, 2026. The actual chances of winning depend on the number of valid entries received.

The selected participant may be notified by email, phone, or postal mail within seven business days of the drawing. A potential winner who does not respond within 72 hours of the first notification attempt, fails eligibility checks, or does not return required documents may lose the prize.

If the selected entrant resides in Canada, the official rules require correctly answering a time-limited mathematical skill-testing question without assistance before being confirmed as the winner.

Prize Claiming, Taxes, and Shipping Conditions

The potential winner must complete the applicable eligibility and release documents within the specified 72-hour response period. Tax documents may also be required, and the winner is responsible for applicable taxes associated with receiving the computer.

The sponsor reserves the right to provide an eligible substitute prize or equivalent cash value under the conditions stated in its official rules. This does not mean that winners may freely choose cash instead of the announced PC.

The prize is provided subject to the organizer's stated conditions. Manufacturer warranties, where applicable, may offer separate protection. Readers should review shipping and fulfillment provisions before accepting the prize.

Official Rules and Giveaway Safety

Read the Mouse & Key Sweepstakes #4 Official Rules before participating. The official rules govern eligibility, entry methods, prize fulfillment, and other requirements.

According to the organizer, potential winners are not required to pay a fee or provide bank-card details to receive a prize. Mouse & Key also states that it does not notify winners through social media direct messages. Be cautious of impersonators requesting payment or account credentials.
