Maximum PC

I have had a power supply fail on my main system that my family uses at home, the Antec True430. I have a Gigabyte GA-8IHXP motherboard, which requires the ATX 24-pin connection, 6-pin AUX connection, and the CPU connection. I would like to find a suitable replacement to this power supply.
Suggestions?

Assuming the rest of the system is more or less "modest"... Any 450W-500W power supply from the following will do:

• Antec
• Corsair
• PC Power and Cooling
• Sea Sonic

As a rule of thumb for me, at this power range, $50 or more on the power supply is a good investment. Cheaper power supplies may deliver power at first, but they may also deliver fireworks or toasted electronics.

Well, that's the thing, I'm having trouble finding a power supply that contains the old 6-pin AUX connector, required for the motherboard to function. As I can see, it looks like this connector is quite rare now. Is there anywhere that I could get one with this connector?
