I need help finding the right power supply wattage and a durable long lasting type. Don't care about looks and it doesn't matter if I can hear the thing running, just no buzzing screeching sounds like the many horror stories I've heard making me paranoid on what to buy :/

GIGABYTE GA-P55A-UD4P LGA 1156 Intel P55 SATA 6Gb/s USB 3.0 ATX Intel Motherboard w/ USB 3.0 & SATA 6 Gb/s
Intel Core i5-760 Lynnfield 2.8GHz 8MB L3 Cache LGA 1156 95W Quad-Core
CORSAIR XMS3 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800)
SAPPHIRE 100283-3L Radeon HD 5770 1GB 128-bit GDDR5 PCI Express 2.0 x16 HDCP Ready CrossFireX Support

And yes I do intend to crossfire eventually just not within a few months.
 
Solution
These are the official recommended power requirements based on your graphics card:

450 Watt or greater power supply with one 75W 6-pin PCI Express® power connectors recommended (600 Watt and two 6-pin connectors for ATI CrossFireX™ technology in dual mode)

This applies to the entire system not just your graphics card.

If you're looking to Crossfire in the future then as you can see you'll need a good 600W unit at the least. If you're looking for reliability and durability then anything from Corsair, Seasonic and some of the newer Antec models will fit the bill. Most PSUs from these manufacturer's come with at least a five year warranty. What you go for all depends on how much you want to spend.

The Corsair TX-650 will be more than...

The Corsair TX-650 will be more than adequate for your needs:

Or you can opt for a modular or 80+ Gold certified PSU if you are willing to spend the money for it. This PSU from Seasonic is both modular and has achieved a 80+ Gold certificate:

Corsair and Seasonic are two brands that have a reputation for high quality power supplies that consistently earn high marks in technical reviews. They are reliable, stable, and come with a 5 year warranty. Some of the newer models come with a 7 year warranty (in the USA).

I went with the Corsair TX-650. Thank you ALL for your fast advice. I really do appreciate it. I got tired of seeing too many games on the PC I want to play pass me by because I didn't have the right comp for it. Finally decided to get one built. Nothing amazing to a good lot of you but I've been going by my set budget at the moment. I am gradually going to upgrade when I can, but right now for my limit I'm just trying to get the right performance for a decent price with longevity. And honestly it wasn't as bad as I thought it was going to be. It's been an interesting experience running around doing all kinds of research for every part. This was the last piece I really needed a word on though and again thank you!
