That's definitely bad news. The 5670 and 6670 are almost the same? Both only require board power. If I should upgrade my PSU as well, which one should I get? I'm a little cramped for space and the newer style PSU's with the large fan at the top will not work. I have the venting out the rear of the unit (PSU's fan and AC plug on same side).
A "computer builder" recommended this combo-430w thermaltake & hd 5450 as entry level upgrades to my factory setup. I have a HP a6502f. I also have a back-up PSU, a cheapy Coolmax V-400 that sounds like a tractor.
If you can recommend an upgraded PSU that will power a stronger, recommended card, I would love to know. Thank you for the quick reply. I definitely should have found this site BEFORE I started buying aftermarket parts.
