Are these any good? the rosewill psu's? 500w here

Hrm, the rails look pretty beefy amperage wise, but I still wouldn't buy one of those. What's wrong with the Antec you have now?

im selling my current rig and buying a whole new one and the psu i dont wanna go cheap on but dont wanna spend 140 bucks on a psu

its gonna be powering a amd643000+ gig of ram and a 6800gt and 4 hdd's and about 1 dvd/cdrw combo burner thing so i want a good psu for it would i be better of just buying another antec like i have now or getting another psu?

im either thinking now that you say that either ocz powerstream 520 watt or x-connect 500w i really dont wanna spend that much on a psu but i still dont wanna have to worry if i upgrade in the future

It's got fat power rails, and there's an even beefier one a little further down the page.
