Im running a HD4870 + 3 HDD's + 2 DDR3 Sticks + PII 545 on a 430 Watt PSU. I was completely amazed when It all worked, and Iv never had any issues with it before. I think it really dependson the quality of your PSU.

That's good to know so it should run on 450 watts. Is there any noticeable difference between a 4770 and a 4870?
[QUOTE="ProudLarry"] As long as you're not running multiple hard-drives or optical-drives, you shouldn't have a problem. But what CPU and how many sticks of RAM do you currently have installed? Im running an Intel Core 2 Quad Q 6600 Processor and have 3 gigabytes of DDR-2 Ram.
I was wondering if I could run an Radeon HD 4770 on my 450 watt PSU. I had run an 4600 previous but it fried. Now I'm running a Geforce 8600 and I'm sorta sick of it not being able to run anything. It also says that the 4770 runs at min. of 450 watts but I'm not sure.
I've been running my 5770 on a 400W PSU for some time now. Granted, the 400W is pushing it, running on a card that requires 500W, and the whole thing is not very efficient. But it is defiantly possible. So it's working fine on your 400 watt PSU or should I just upgrade the PSU as well?
