That's a Chokemax PSU. It wasn't designed to power sensitive electronics, like a computer, although it may be suitable for 300W-400W worth of light bulbs. If you're lucky, it was dead before you tried to use it, so it never got the chance to damage your computer when it died.
A quality PSU has full range active PFC (no little voltage switch) and 80+ certification. You do not list the rest of your specs, but unless you're using something MORE power-hungry than a HD4850 or HD5770, most likely all you need is a 380W Antec Earthwatts.

Your GPU sips juice; it isn't a gaming card. Even if you wanted a newer HTPC card like a HD5450, you wouldn't need a bigger PSU.
Just be aware this PSU doesn't come with a power cord, so save your old one.
Edit: As to noise, I installed one just a couple weeks ago in my Mom's PC, and had to double check that it was on when I first flipped the switch. It is almost inaudible.
Your looking at a defective PS or a rare problem where the PSU and motherboard just don't like each other. Thats why you sometimes get a product review where the guy claims the unit was defective and 1 or more identical RMA replacements also failed.
This assumes the board is known to work. And the PSU is the only new component.
His board works, with another [very noisy] PSU. Given that the new PSU is a Chokemax, that looks like the pretty obvious culprit. For one to work and not another discounts a cabling error as well, like forgetting the CPU power cable.
