Will Ati radeon 4870 run fine with my PSU?

Tue Feb 03, 2009 3:43 am

Hi.. Everyone here..

I am going to buy new Sapphire Radeon 4870 512Mb to replace my old X1650.
The problem is that i am worry about my PSU if it can handle and run fine with this video card.

here is my rig:
PSU is Acbel E2 510W with dual 12V rails rating at 18amps each and a 6-pin PCIe connector.
MB ASUS P45 Neo-F
CPU Q6600
2x2Gb Adata pc 6400
monitor Dell SE198WFP

I have read the system requirement for the Radeon 4870 from amd's website, the minimum is 500W and two 75w 6-pin PCIe connectors
but my PSU have one PCIe connector, that mean i have to use 4 to 6-pin adapter and my MB use only a 12V rail. ATI 4870 draw power when load over 270W when full load http://techreport.com/articles.x/14990/15.

Will ATI 4870 run fine on my system??

Thanks in advance for all comments..

Hmm, I have two 3870's running in xfire on a 550 watt psu. I think they are more power hungry than there older bros the 4870's.

I'm not crazy about Bestec power supplies, but you should have plenty of capacity for a Radeon HD4870. It's the total +12V capacity that matters.

You should notice a significant improvement in your gaming experience when you upgrade from the Radeon X1650.

Would appreciate more details. Each rail may be capable of supplying 18A but their combined wattage may not be be 36Ax12=432W. Look at the label and see if there is any clues as to the combined amps from both 12V rails.
The Model M is not for the faint of heart. You either like them or hate them.
