I'm building a new system and just need to know if this Corsair VX550W will be enough or if I should get this Thermaltake 600W Litepower

Components:
ThermalTake Soprano DX Midi-Tower Case - Aluminium Front Panel (VE7000BWS) | Techbuy Australia
Intel Core i7 860 Quad Core (2.80GHz - 3.46GHz Turbo) (BX80605I7860) | Techbuy Australia
Gigabyte GA-P55A-UD3P Motherboard | Techbuy Australia
Kingston 4GB (2 x 2GB) PC3-10600 1333MHz DDR3 RAM - CL9 (KVR1333D3N9K2/4G) | Techbuy Australia
Sapphire Radeon HD 5770 - 1GB DDR5, 128-bit, 2x DVI, HDMI, Display Port, Fan - PCI-Ex16 v2.1 (21163-00-41R) | Techbuy Australia

And also 2 Harddrives: 1 250GB and 1 1TB.

So any suggestions? Also, if you want you can give advice about the build its my first.

If your gonna suggest another PSU price range is below $116 (USD)

PS: I dont plan to overlock

I'd strongly recommend the Corsair HX series. I've got the 620 and it's a great power supply. And it's modular so you can keep your wiring super tidy

A good rule of thumb is to add at least 50% to the total peak power consumption of all your hardware. A power supply operating too close to it's maximum capacity can cause crashes and instability, and won't last as long.

It could hurt the pocketbook.

I've also seen situations where people just want more wattage and thus end up with more cheaply made power supplies to get a higher power output...rather than going with a smaller unit that is a far better unit.

The only things that I can add to what has been said, is to get a modular power supply, and check how many +12v rails it has. Some PSs with more than 1 +12v rail splits power between them in an uneven manner, making it easier to overload the lower powered ones.

EDIT: Another thing that is good to have is sheeveed cables, which are easier to route and neater.

really your power supply isn't somewhere you want to cheap out on. go name brand and get enough extra headroom for a saftey net. you don't want to risk that thing blowing on you.

Overall, I agree with this, but name brand isn't always something to go by. I've had several Antec PSs, one of which fried a motherboard and video card, and at least at the time that I got them, they were considered very good, but The Cooler Master that I now have, which is not at the top of most lists, has held up steadily for 3 years now, without it burping, gasping or croaking. It wasn't particularly cheap, but not expensive either.
