AsRock said: Ever thought they say 750w due to cheap PSU's, although i still like a 200w head room for a few reasons.



EDIT: Even more so when the Newegg sales happen on PSU's picking up a Seasonic 750w PSU for 90-100$ is hard to say no too.



At this time they have a 650w for 90$ and a 750w for 119$ including the 10$ rebate. Click to expand...

well yes ... as i always had good PSU (if we except a Chieftec and a Thermaltake ... who weren't too bad but not top notch either) tho most PSU calc webapp give a roughly accurate minimum and recommended wattage, ofc if you don't know what you have inside and maybe have a more power hungry setup then you might reach the "recommeded" crap made up by the manufacturer... but if you know what you have and have access to some webapp calc site (i use http://extreme.outervision.com/psucalculator.jsp almost every-time, updated recently tho ... ) then you can adapt your card/psu to what you can use within your range (price/ambition??? whatever)i got my M12II 750 for 109chf (and it's the regular price where i am, in Switzerland they rarely do Sales or rebate...) the Integra R2 i had was 85chf, the InWin IC III DF was 119, and the cheapest i have actually (but still hold fine) is a Cooler Master GX Lite 600w at 59chfwell i also like having a headroom, that's why i swapped my 650 for a 750 (iirc too much headroom in the end is just as bad as being over the limit... but i can't remember why and where i did see thatsooo i might be totally wrong
