I like your choice of hardware. I would look at getting some different ram. I'm a Mushkin fan myself as they are great memory with lifetime warranty. They are well respected by everyone I've ever dealt with and are great for overclocking, as well as being durable.
I looked on the Canada Computers website and found their redlines for a good price. A lot of the HWC members also like G Skill because of cost and performance. Have a look at Corsair, Silverstone, and a few other psus.
Corsair power supplies are another durable and well respected piece of hardware. I use both items mentioned and haven't had so much as a hint of trouble from them. Check out the Buy/Sell/Trade section for possible savings on quality components at great prices.
Good luck with the build and enjoy!!!
