I have a Sapphire Vapor-X Radeon Hd 7770 and i am worried what power supply should i buy for it. I was intending to buy Antec VP550P 550w PSU and wanted to know if it's good and compatible. I also wanted to know if this psu has a high fan volume or not. Also wanted to know if this is compatible with the GPU I am willing to buy?

Before recommending a PSU we need to know what else you have that will draw power. Namely:

CPU and clock speed.
RAM frequency.
All storage devices.
All peripherals.

According to competent technical reviews, budget CM PSUs are little better than junk. HardwareSecrets has reviewed quite a few of them over the years, and HardOCP and jonnyguru have done some as well.
For a HD7770, unless you've got a stack of hard drives AND a heavily overclocked 100+watt CPU, a 380W Antec Earthwatts would be my quick and easy choice for you. If not available, the modular Corsair CX-430M (not the non-modular CX-430) would also be suitable. All of the Corsair CX line are made for them by CWT, but the non-modular ones use some inferior Samxon capacitors that don't like heat and are known for early failure. I would not use one in a gamer. OTOH, the 380W Antec Earthwatts has been my "goto" PSU in budget builds for years, and I have yet to have one fail.

I found this review of their "475" Watt unit, the littler brother to the one you are considering.
http://www.hardwaresecrets.com/article/Cooler-Master-Ex...
Brands to buy, reputable brands: Seasonic, XFX (made by Seasonic), Corsair, Enermax, Antec, and PC Power&Cooling.
Take a look at the list that jimthenagual posted. Consider a Corsair CX modular.
CORSAIR CX500M 500W ATX12V v2.3 SLI Ready CrossFire Ready 80 PLUS BRONZE Certified Modular Active PFC Power Supply.

Or this xfx:
XFX Core Edition PRO550W (P1-550S-XXB9) 550W ATX12V 2.2 & ESP12V 2.91 SLI Ready CrossFire Ready 80 PLUS BRONZE Certified Active PFC Power Supply .

The lying noted about the "475W" version of the CM PSU is typical of the brand. That is unethical, and I therefor cannot with clear conscience recommend ANY product of the company, no matter how good.
You aren't looking for high wattage, but for high quality. I stand by my earlier recommendations. While playing games, you are unlikely to actually use more than 220W-250W, which makes a 380W-450W PSU a comfortable size.

This is one of the best compiled lists out there of which PSUs are good, and which are trash. Stick to a tier 2 or above.

Maybe I'm lucky but I've been running a tier 5 ATRIX PSU for five years now.
