Hi guys I'm new here and I wanted to know can a 5670 run on my comp with my psu its 300w and has 19 amp on the 12 v rail. I know the amps is a bit low but my comp is very un power hungry here are its specs. Thanks so much for the help.
It should work fine here is a power benchmark where the get a total system power under load 190watt http://www.anandtech.com/show/2935/13
Just make sure if the motherboard has a PCIexpress x 16 version 1.x slot that you buy a version 2.0 card not 2.1
You'll be fine. The HD 5670 doesn't consume more than 30w of power under normal gaming conditions. If you were to use a FurMark to stress your card then it would probably go up to 40w - 45w. Overall your PC doesn't really use much power.
Additionally, do not bother getting the 1GB version since the 512MB of RAM does not improve performance (see review below):
Thanks i keep worrying about the amps everyone says thats most important but seeing as how my system doesn't use much power I guess there is room for the GPU. Btw howmuch amps is used by everything but the cpu and gpu?
