Enter here for a shot at winning an XFX Pro Series 650W PSU

We've reached the third and final stretch of our XFX power supply giveaway marathon. This time, the prize is one of XFX's Pro Series 650W power supplies, which is worth a good $90 before shipping at Newegg. To enter the contest, simply read the rules and regs below, answer two easy skill-testing questions, and fill in your contact details. (As always, we'll keep your personal information confidential.)

XFX's Pro Series 650W power supply features a single 12V rail with 53A (or 636W) of output capacity, and it otherwise has the exact same perks as the Pro Series 850W and 750W PSUs we gave away last month. That means 80 Plus Bronze certification, five-year warranty coverage, and support for both Nvidia SLI and AMD CrossFire multi-GPU configs.

Hats off to XFX for providing the three power supplies for our giveaways.

Rules and regulations
Sorry, but this contest is open to residents of the U.S. and Canada (except Quebec) only.

To enter, fill out the form below, correctly answering two easy questions. The answers are revealed clearly on the Pro Series 650W product page on XFX's website.

Only one entry is allowed per person, household, or e-mail address. Multiple entries per person, household or address are not permitted. Please don't try to game the system by entering your girlfriend, wife, kids or pets. We'll probably disqualify you if you do.

We will be accepting giveaway entries between the time this post goes up (April 1) and April 6 at noon CST. We'll then choose our winner in a random drawing from among all eligible entries. The winner will be announced on the site and will also be notified via e-mail on April 6. The winner must claim his prize by the end of the day on Sunday, April 10, or he will forfeit his prize and we will draw a new winner.

You must include your full name and a physical shipping address with your entry. Only the winner's name will be announced on the site. We will not share the address or other personal information with our sponsors or anyone else. Incomplete entries will be disqualified. TR reserves the right to disqualify entries that appear to be attempts to game the system or circumvent the rules in any way.

The staff of The Tech Report and their immediate families may not enter the giveaway and are not eligible to win.

We will accept entries only from residents of the United States and Canada (Quebec excepted). No purchase is necessary. This giveaway is void where prohibited by law. Neither TR nor XFX is responsible for any taxes on the prize, damage in shipping, damage caused by using the prize with other products, or health issues such as RSI, eye strain, or chemical addictions that may result from prolonged use of the prize. We may answer questions and offer clarifications of the rules in this comments thread.
