Mga bro Ive found out these when visiting HEC website about OEM products like PSU's.
See the website and search most Power supply manufacturers like Silverstone, Coolermaster, Antec, Gigabyte etc.. what the HEC ang nag buhat so meaning re branding ra jud diay ni ang gibuhat sa uban manufacturers.
80 Plus PSU - Details
The only difference when buying HEC and or other products psu kay ang warranty ra and the rest are the same. Now I know.
