i just bought an el budget gigabyte hercules x 580w for RM 140. Its just for a basic core i3 with an old 9400gt card. Cannot find any review or test because this a newly launched unit since april this year. I think its pretty good quality. Runs quiet and not even warm like my old cap ayam did.

I had good experience with the old gigabyte 350w power supply that lasted 5 years before a bad surge killed it. I though of trying other brands but cost and on paper value seems better on the gigabyte x 580.
