480W Power Supply enough for XFX ATi Radeon HD 5770? (Urgent)

[Guest]

Hello,

I am new to this forum, so I apologize if this is in the wrong category! I have been wanting to upgrade to an XFX ATi Radeon HD 5770 for awhile now. I'm getting bored of running Battlefield Bad Company 2 on low settings with my XFX ATi Radeon HD 4670. I wanted to know if my PSU is good enough for it. I saw that on tigerdirect.com, the memory speed is 4800 MHz, which seems a bit high to me. The recommended PSU is 450W, but I don't want to burn out my PSU because of stress and so on. Here are my computer specs:

Windows 7 Home Premium (64-Bit)
AMD Athlon II X4 620 @ 2.6GHz (not overclocked)
4GB DDR2 memory (2 sticks @ 2GB per stick)
XFX ATi Radeon HD 4670 (not overclocked)
480W Black Steel PSU

If this helps, these are the numbers on the 2 rows of my PSU:

Row 1: |+3.3V| |+5V| |+12V| |-12V| |+5Vsb| |Total|
Row 2: |28A| |34A| |18A| |0.8A| |2A| |480W|

This is the card I want to buy: http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=5316156&CatId=3669

I was hoping to buy the card this weekend, so any help would be great ASAP!

Thanks -- gotsupra1337

That is a old ATX psu with a low amperage for the +12volt rail so I will have to say no. A more modern PSU is needed.

No, that PSU is equivalent to a modern "300W", it really only has 216W of useable power.

It should power the 5770 on though, but it is way too close to the line that I would recommend a new PSU.

Thanks for the quick responses everyone! So, with the PSU I have, what is the best car I could run with with no risk of instability?

Just get a new PSU, it will be worth it.

It will run a HD5670 but you would be happier with a new PSU.
