I'm looking to buy a psu for my new build and I'm wondering which I should get.
My spec's so far:
Cit fortress USB 3.0 (bought already)
Asus P8B75-M LX Motherboard (bought already)
Intel i5-3570K CPU (bought already)
Ram 8gb
Ssd drive for OS and a hdd for later
Radeon hd7850 2gb graphic card.
Please help?
