Couple days ago my psu shorted and blew up. A link to my pre-built pc is; http://www.expertreviews.co.uk/pcs/1286446/acer-predator-g5900

I have tried browsing many shops irl and on the internet for psu suitable for this pc. My biggest problem is the motherboard only has a slot for a 4 pin PCI-E Power input. Every psu I have searched has been a 6 pin, 6+2 pin, or 8 pin. I can afford a new psu of around 50-100 but am unable to afford the 500-600 I'd like to spend on getting a "new" pc. Any links to a psu that will work for my pc would be greatly appreiciated and if I could even get a psu to work all the better. Thanks :)
