ive never heard of that company , anyway from what i can see on google thats cheap aswell , still i think its the psu i recommend getting a psu from a known & trusted psu company one of these --> (pc power and cooling/ocz/tagan/enermax/antec/thermaltake/fortron fsp)
yeah they are more expensive then the avrege cheapo psu but unlike a cheapo psu they will hold up your pc at ease , and if your starting to doubt its the psu at fault you know what you can do to be 200% sure ^^
