Hi.

Here are the system requirements for the 4670

ATI Radeon™ HD 4600 Series System Requirements

PCI Express® based PC is required with one X16 lane graphics slot available on the motherboard
400 Watt or greater power supply (550 Watt for ATI CrossFireX™ technology in dual mode) is recommended
Certified power supplies are recommended. Refer to http://support.amd.com/us/certified/power-supplies/Pages/listing.aspx for a list of Certified products
1GB of system memory recommended
Installation software requires CD-ROM drive
DVD playback requires DVD drive
Blu-ray™ playback requires Blu-ray drive and full 1080p display requires a 1080p-capable monitor
To enable dual mode ATI CrossFireX™ technology, a second ATI Radeon™ HD 4600 Series graphics card, an ATI CrossFireX Ready motherboard and one ATI CrossFireX Bridge Interconnect cable (included) is required.

The recommended PSU is for the entire system so only the Gigabyte 550W SMPS meets the Crossfire requirements but Gigabyte is only good for Motherboards and GPUs not for PSUs.

Go with one of this options:

1- CORSAIR CMPSU-550VX
2- Corsair CMPSU-650TX
3- Corsair CMPSU-650HX

The last two Corsair PSU can handle any future upgrade and Crossfire that u want to do until the 5870.

forget the gigabytes, i would not trust them to CF anything

the antec, corsair and seasonics would be what to look at. all four offer similar amps on the 12v, 29 -32 (antec is at the top). The two seasonics are bronze certified but the corsair (made by seasonic) and antec are only slightly less efficient. You can't go wrong with any of those. check to see they offer as many connections as you need for molex & sata as lower cost units tend to skimp on them.

if antec is at the top then should i go for antec430 over seasonic430?

actually they are both at 30a. like i said, flip a coin. you can't go wrong with either one or the corsair.

30a?? antec is cheaper.aint it?
