Power Recommendations by Video Card

That's all that I need to know. Thanks!
To get a close amount of amps. Take the total of watts on the 12V rails (not the P/S total watts but just the 12V rails) and divide it by 12.

nice.. didnt know the 3870 were that low on power usage... =o might go for Ati after all on my next grafic's card
I've said the same thing, that 3870X2 looks tempting...
ceewi1 what do you think it requires for Crossfire of 3870X2's?
Thanks

Most 7 series or lower end 8 series SLI wouldn't be a problem. I'd say a pair of 8800GTSs is a pushing it a bit for long term use, though.Ah, lol, Ok sure
Oh, also, my PSU says it's SLI ready... I think it puts out 40A... that'd only be able to run a few of the 7 series' SLI?
Yeah - this is another useful link - http://www.xbitlabs.com/articles/video/display/radeon-hd3870-hd3850_13.html#sect0 - power consumption for just the video card.nice.. didnt know the 3870 were that low on power usage... =o might go for Ati after all on my next grafic's card
There's not much info available yet, but if I had to guess I'd say you'd be looking at numbers similar to the 2900XTs.
The 8600GT only comsumes ~30W itself, so I would say you'd probably be OK. Be aware that the quality of PSUs varies dramatically - a lot of lowend PSUs will not put realistic power ratings on their units.

Mine says it's a "Hipro" on it, I assume thats the brand? I will probably upgrade my PSU just to be safe. What is the "worst case scenario" if the PSU doesn't work?
This is a great thread and should be a sticky or a link should be put in the CPU 101 thread or Graphics Card thread 101. Being someone that is learning about all this stuff it's making things a lot clearer for CPU selection with what card I might want to run, weather it's old or new.
I hope it continues to get updated with the old and the new.

Likely you'll end up with stability problems and random restarts either now or some time in the future. It's possible for a cheap PSU to damage other components if overloaded, however.
Thank You, I'm glad it's worth the effort. This thread is linked in the http://www.computerforum.com/90118-useful-psu-case-guides.html sticky and I'll endeavour to keep it updated. As for linking to it in the 101 guides in other sections, that's really up to the mods for those sections.This is a great thread and should be a sticky or a link should be put in the CPU 101 thread or Graphics Card thread 101.

I have an X1650 ATI card, it requires 550 watts, not 350, Unless my box is wrong.

Are you sure that's not for Crossfire? I took my numbers for the X1650 series straight from ATI's website:
http://ati.amd.com/products/radeonx1650/radeonx1650pro/specs.html
http://ati.amd.com/products/radeonx1650/radeonx1650xt/specs.html
550W would really be too high a requirement for X1650 series cards - since they draw between about 45 and 55W peak, it would be out of step with the requirements for other cards with similar real-life power draws.

Looks like you're not the first one to have this - see my response at http://www.computerforum.com/889701-post36.html.
These recommendations are for the entire system, an X1650Pro should only draw ~45W on its own so a 550W recommendation seems excessive.
