Default 250 Waltt for 4850
Hi,
I was going to upgrade my other p.c today to a 4850 but realized that it only has a 250Watt PSU is this enough to run this card.

Thanks

no way
get like a 400w minimum.

Specs call for a 450w with a 75w 6-pin. 550w with 2 6-pins for crossfire


EDIT: what is up with the sig rig/question discrepancy? lol!

Yep.



Those of you who keep reading the minimum from other pages of theinternet. Be quiet. I ran my e2180 3Ghz and 8800GT on a 300w 22a 24/7 for two weeks.




Your 250w MAY run it in 2D mode.

Just avoid generic and off-brand stuff, and get somewhere in the neighborhood of 400 watts and you are butter. This is a decent little unit. Ran my 4850 just fine.

please dont talk down to other members. its very tacky.
as most have said it will not work. but redsunx thinks you can. so the question is do you really wanna find out by using that psu with a chance of it shorting out and maybe taking something with it, or being safe and getting a new psu too?
