Just bought a new video card (see specs below), the manufacturer says 450W minimum, and the place I bought it from says 600W minimum requirement. My current stock PSU is apparently 300W. I have had a few people (from these forums) suggest that I try the card with my stock PSU and see if it can handle it or not, but after doing some research, it seems like the card idles around 80W-100W and with a load goes up to around 250W. (http://www.anandtech.com/bench/Product/536)
To me, it seems like these numbers are pretty indicitive that my 300W PSU won't be enough. But I was hoping to get some feedback from some people who are more knowledgeable on the subject.
1. First, what are your thoughts on these W numbers (min recommended, apparent card usage, etc)?
2. Secondly, If I do need a new PSU, what wattage, and even better, what unit should I go with keeping in mind I am a poor college student.
oh, thanks for the quick responses! i didn't realize it was the complete system (silly me!), which is i guess why i asked. So you guys think i should give it a try with the stock 300W psu and see if it is adequate? this won't harm any of my components or anything if it isnt?
what should i look for that would indicate that it might not be enough power?
ps. i have not seen that card & PSU combo tested elsewhere and i even searched beyond these forums (the whole WWW)
edit: and why does the manufacturer, amd, (and especially tigerdirect) have such high min PSU recommendations when the highest load i have seen from multiple sources is around 250W?
The recommendation has to cover a whole multitude of different combinations hardware.
A fully loaded case, extra lights, bells, whistles and weak PSUs all have to be accounted for in a near-worst case scenario.
In your research over at the HP forums what were some of the other graphics cards successfully run on that same PSU?
