Hello,
I have a 650 watt psu with 2 rails of +12v 16 amps. one of the rails is a 6-pin connector. My question is this psu good enough to run a ati radeon 5770

32 amps is quite low for a 650w but even so it should be fine for an HD5770.

Yes, it's a quite low for 650W PSU. Even my 500W PSU has 2x 18amps on 12V rails.
But like jyjjy said above, it should be able to handle HD5770... :)

I seen a report that says the 5770 runs 19Amps, can't recall if that was underload or not though.

So i see you advise mee to buy the 5770. so i will buy it. if the power is'nt enough I will buy another PSU with 38@mps and sell my current psu for a friend.

is this a good idea.

my system current info: windows 7-64bit pentium Dualcore E5200, 3gb memory, hitachi 150gb 7200rmp hdd, seagate 250 gb rmp7200 hdd, evga 9500gt ddr2 1gb

You won't have any problems with your power supply. I have a 550w power supply with 14 and 15 amps on the 2 rails and i run a vapor-x 5770 overclocked video card and my CPU is also overclocked to 3.4 from 2.67Ghz.

Buy the card and enjoy it. It will be worth it :)  .

And i know that my PSU has a low amperage for it's power but i have it for 2 and a half years and it was not a new model when i bought it.

19a on the +12v rail is 228w. The HD5770 doesn't use anywhere near that much power. It tends to max out at about 85w under normal usage, about 110w during stress testing.

The E5200 can go higher than that. Even just on the stock cooler 3.3-3.5 ghz should be fine.

3.325ghz would be a good choice. Just bump up the voltage a tad and set the FSB to 266mhz and you should be good to go.
