Quick Overview

This unit will power most midrange systems with single graphics cards.  It will even run a dual card system for the lower end GPUs and represents an excellent value unit for a mid-range gaming system. FSP have built a name, not only for cracking prices and value, but mainly they are best recommended for their excellent reliability. Performance is one thing but the psu has to go on and on without fault.
