Hi everyone, was thinking of upgrading my GPU to a Radeon HD 6850. I hear that you need a minimum of a 500W power supply. However, I don't have power hungry specs. Does the fact that I have only 4GB RAM and a Dual Core Processor mean that I can cope with my current 400W supply for the HD 6850. Thanks In Advance.

System Specs:

Operating System
MS Windows 7 Home Premium 64-bit
CPU
AMD Athlon II X2 250
Regor 45nm Technology
RAM
4.00 GB Single-Channel DDR3 @ 401MHz (6-6-6-15)
Motherboard
ASRock N68C-S UCC (CPUSocket)
Graphics
F22 (1920x1080@60Hz)
ATI Radeon HD 5400 Series (ATI AIB)
Hard Drives
466GB Seagate ST350041 3AS SCSI Disk Device (ATA)

I have a similar system (with HD6850) running on 400watt quality PSU so if yours is quality you are fine

Okay, thanks very much for the quick reply! Thought about the 6770 but heard 6850 can cope with 1080 resolution better.

You are right the 6850 is much better.
