I'm planning to get a Sapphire Radeon HD 7870 Ghz edition but it it requires 2 6 pin connectors. Unfortunately as far as i know my psu has only one. So how can i connect it? Also i've calculated on extreme.otervision.com the approx. wattage i need ~410 and my psu is 420W so its enough. again, the only thing i'm aware of is how i'm gonna connect the gpu.

CPU:AMD FX-8350
RAM:2x8Gb Transcend JetRam DDR3-1333
MoBo:Gigabyte GA-990XA-D3
