A good Power Supply is an investment, not only in the present problem, but also in the future. A good PSU will follow you from case to case, motherboard to motherboard, processor to processor, etc. Read: Long term investment. Good Power Supplies, with an eye towrards the future, will cost more, but the cost can be recovered over time since you won't have to keep buying more powerful ones in the future. I'm not sure what you would call a "Ton of money", so I'm not sure what to recommend to you. Antec power supplies deliver. Plain and Simple. So do PC Power and cooling. To a lesser degree, Fortrons are good also. If you look at the Antec True430, 480,or 550, there's only about $10 difference between each step. Given that a good power supply will last many years, the initial cost can be money well spent. You can have overclocking issues that are caused by a power supply that do not show up when reading the static voltages and certainly if those voltages are read by the onboard sensors. By providing your system with a known-good power supply, you remove that variable from the list of potential causes for a poor overclock. They are not the only factor in an overclock, not by a long shot, but they are a variable that throwing some money at, will often remove them from consideration. Every make and model of any product will have the occasional lemon, so be prepared for someone to quote you how their high-buck PSU was a POS. Than applies equally to a motherboard, CPU, whatever. Look to the group average opinion of this stuff, not the extreme examples, either positive or negative.
FWIW, a while back, I had an Antec 400W power supply that went belly up. After contacting them and entering into a dialog with a Customer Service person, I made them comfortable that I wasn't just some "snot-nose" trying to scam them out of a power supply and they sent me a new one, sight-unseen. I didn't even have to return the bad one. Now, that's worth paying for.
