AMD Radeon 7850 2gb power supply

[Slash2004]

Hi,I have just got a XFX AMD Radeon HD 7850 2GB Graphics Card, it has 2x 6 pin pci connections on it, however the website states that i only need 1x? (http://www.amd.com/uk/products/desktop/graphics/7000/7850/Pages/radeon-7850.aspx#2)

Can I just plug my 650w psu into 1 of the 6 pins and will it work or will i need to buy a new psu?

Thanks

You must plug two 6 pin pcie connectors to supply enough power to your graphics cards. What are you system specs? Do you only have one 6 pin pcie connector in your power supply?

AMD FX8350 8 core @ 4ghz
Gigabyte 78LMT motherboard
the GPU im having trouble with

my PSU is a Powercool 80 plus 650w but only has one PCI connector that can be a 8pin or 6 pin

I suggest to replace your current PSU with this http://uk.pcpartpicker.com/part/xfx-power-supply-p1550sxxb9

Better components and very reliable PSU made by Seasonic.

i have the same card, im assuming the additional power is required due to non-reference cooling system

and you can just get a molex to 6 pcie adapter

cheers guys, i was just confused that on the site it said that you could use 1x, i'll probably try pick up a molex tomorrow.

Thanks
