easily. the HD4650 agp uses only 48w maximum so it will be fine. it will work well with the pentium 4.

What if it is lets say 14 amps on the +12V rail... I actually dont know how much but how many amps is required to run this card?

48/12 = 4 amps to run the card. You are good.

1GB ram is the minimum needed for windows 7. you should be at 2gb ram at least, although im guessing since your using a pentium 4 you wont be playing modern games.

Will it work on a 250W PSU from Aastec? 10 amps on the +12V

with 10amps on the 12v rail you should stick with a 5450, maybe risk a 5550/5570.

You went from 350 to 250 ?

Anyway, I have a P4 3.0 clocked at 3.6 on an Asus P4C800-E with a single 1gig stick of DDR400, 2 x 80g HD's, single OD, a Radeon 9800 Pro and a couple of 120mm LED fans.
The 9800 Pro has basically the same power consumption as the 4650.
According to my Killawatt meter it draw 235 watts from the wall when running OCCT and ATI Tool, being generous and saying that the old Enermax psu that's in there is 75% efficient gives a psu load of around 175 watts.
That would be a 70% load on a 250 watt psu, when stressed, it shouldn't be a problem, but I'm not reccomending it.

The main concern from me is that 10 amps(would be very close depending on the rest of your hardware) on the 12 volt rail.

That means all 12 volt devices have to share 120watts(10x12). Clearly its an older power supply from the days when 5 and 3.3 where used for more(or an underrated unit, i have seen some that have heavy 5 and 3.3 to give it a rating of 500 watts yet it pushes less usable power then a 300 watt). On modern systems, the 12 volt rail runs more of the system.

well, getting a GPU designed for 250W PSU will be a complete waste of money.
Try some nice combo lyk
Getting a new good PSU with 450-500W(the new and newer cards won't be demanding more) and a good mainstream card lyk 512 gt 240 or HD 5670 with ddr5 memory.

4650 won't run on 250W PSUs unless if its a Dell or HP
