Bought a power supply and hard drive from Ace at yamanto. Upgraded the rest from umart. No trouble…read morewith the hard drive. Took the power supply back the first time as it didn't power my pc. We got an exchange of the same brand as thats all they stocked. Bought it home and it still didn't power on my pc. Plugged in my 650, and it worked fine.. so I set abt installing and updating, planning to return it as soon as I could. A week and 2 days later, I tried to return the power supply and the old man wouldnt let me, he alluded there was no problem with the original power supply and refused to refund the second one. Reckons I was 'using it' but even if i was using it, if it doesn't work after the week, that's still a crappy product isnt it?! Now im stuck with a power supply that doesnt work in my pc. Im not sure what the old man thinks is fun, but id rather be playing my pc, than making false claims about ya faulty shit?! Bad business really, touting offers off support when 'buying local' and then treating me as a liar. Here is my pc working with my 650 power supply..
