Hey all, I'm looking to upgrade an old OEM XP machine with new components, my current PSU is a meager 250w but ti runs everything fine. But I'm looking to power a new Galaxy GTS250 1GB and @GB of 800 mhz DDR2 ram. As you can see I'm going budget and would like to know which PSU to get this: http://www.newegg.com/Product/Product.aspx?SID=-B5_eHbYEeGoXM5lAEKLqQ0&AID=10440897&PID=1225267&nm_mc=AFC-C8Junction&cm_mmc=AFC-C8Junction-_-cables-_-na-_-na&Item=N82E16817341047 or this: http://www.newegg.com/Product/Product.aspx?Item=N82E16817139026&Tpk=cx430. Both are jonnyguru reccomended, I get the CX430 for 17 and the OCZ ZS for 23. I do plan on overclocking my GTS250 as I can afford to due to the rest of my system being low power. Also which one would typically cool better as my cooling is not very good in this case although its never gotten hot as far as I can tell, I'm worried about the GTS250 running too hot. One of final thing will these PSUs fit in my case its roughly 7"(W) x 15"(H) x 16"(L). I believe that my case is fairly empty with all OEM components except the GTS250 and a hardrive.
