I just started building my first pc build and i made the mistake of buying a cheap non-modular power supply (CiT 850W 12cm Silent Fan Dual Rail Power Supply). The problem with that is that the cable it came with is only a 4pin CPU power cable, whereas my motherboard (Asus P9X79 PRO) and CPU (Intel i7 - 3820 ) both require the use of an 8pin CPU power cable. Are their any converters from 4pin to 8pin that I could use and that would work , or a converter from molex or cable to an extra 4pins. If I can could you please add a link to where I can buy them from (I live in U.K. so would prefer not having to buy it from abroad).
