Hey all, I have an older 4 pin power supply. I really wanted the newer 9600gt nvidia card, but my power supply is only 4 pin, even my backup supplies are 4 pin. So, I still want to upgrade my vid card. All that I have now is the 7300gt. It does have HDR lighting support, but the graphics power is just too low for the games I want to be able to play. What is the best card that I can buy for my power supply. I'm thinking it will be a card in the 8000 series. PCI-E

MB Winfast SIS-761GXK8MC

AMD Athlon64 processor 4800+

A-power 500 Watt PSU 4 pin connector

1GB DDR SDRAM

How many amps on the +12V rail(s)? Your power supply may be good enough. You could get a 6 pin adapter cheap, some video cards even come with one.

Most video cards that require 6-8 pin adapters include them in the package already, unless it is some whitebox OEM setup. Like Sterling14 said, check your 12V rail(s), and go from there.

12V is 28 amps. 3.3V is 30A and 5v is 38A. What do you think? Will this do?


I have in a Mad Dog right now. Supposed to be better than A-power, but it only has a 20A 12V rail and it's 350 Watt.

A power supply at 500Watts and 28a on the 12v rail should run a 9600gt fine.

A 350 watt with only 20a on the 12v rail is really pushing it. I wouldn't recommend it.

Thanks Sterling and Punisher. I'm getting ready to order that vid card. It's since then come to my attention though that PCI-E and PCI-E 2.0 aren't always compatible. My MB is PCI-E 16X. I have read that the 2.0 is backwards compatible, but perhaps that doesn't always mean it will work with an older PCI-E x16 slot. I just want to be sure that it will work with my MB before I order the part. Everything I have found and read online concerning my MB (listed in first post) doesn't really indicate much on this topic. Most all of the reasonably priced 9600gt's are 2.0. And, there is quite a jump in performance capability from even the 9500gt. So, I wouldn't want to settle. Any suggestions on how I can find out?

I don't know where you are getting that information, but I'm pretty sure pcix16 and pcie 2.0 are 100% compatible.
