Desktop computer upgrade: GPU and power supply?

Dear everyone,

I was wondering of if you guys could help me.

I have this Lenovo M910 Thinkcentre desktop.

I need to upgrade the video card for gaming and would like to buy this graphic card Radeon R9 280x http://www.tomshardware.com/reviews/gaming-graphics-card-review,3107-4.html

I was told to upgrade my power supply, and was looking to get this one http://www.misco.ch/product/400049321/SHARKOON-WPM700-V2-700W-ATX-PSU-80PLUS

So 1 basically have 3 questions:

1/ are the graphic card and power supply compatible with my desktop?

2/ is the 700w power supply sufficient? I don't have anything fancy: 8gb ram, 1hard drive 500gb (but might consider a second one) and a dvd drive.
I read on Amazon, someone said to get 750w minimum… Is it really nevessary?

3/ do you know where i can get a video tutorial to install both components? Its really my first time doing it.

Thanks very much in advance for all the help you can give me!

The power supply IS compatible with your system. It also seems to be a decent quality unit, 80+ EER, 54A on the 12V rail, so yes, it can provide more than enough power for your system and the 280X. Most 280X's require that you use a 500W or greater power supply, so 700W will leave plenty of headroom for add-ons and future upgrades. Good choice.

Before you buy the 280X, you'll want to open your systems case (powered down, of course), touch the metal case frame to "ground" yourself (neutralize the chance of an electro static discharge) and measure internally from the rear of your system to your hard drive bays to see if you have enough room for the card. Card lengths vary from the different card makers, and the cards length can be found from the card makers website. Be sure to "ground" yourself again before removing the card from it's anti-static bag and installing it. Good choices, good luck and game on.
