300W with 9700 Pro

Would an Antec 350W PSU be enough for this rig?

Athlon 2100+ 1.73@2.4 1.75v
Radeon 9700 Pro
5 80mm fans
2 7200rpm HDs
2 Optical drives

The rig was running fine with an 8500 and an old Antec 300W but when my brother put in his 9700 Pro... 5 restarts later and it couldn't go into windows... 🙁 We put back his 8500 and it works fine. It seems to happen only when we change something in the bios after we install the 9700 but I'm guessing it can't supply enough juice.
 
In my GBox, I have the following running on a 150W PSU:

P4 1.8
2x512MB PC3200
100GB Western Digital SE
Radeon 9700 Pro
Lost-in-Space LCD
32X CDR
4" Cold Cathode

I'm not saying that this means yours SHOULD work, but it's just an example. PSU quality has as much to do with it as plain power output as well.
 
:Q 150W? 😀

Hehe... well his PSU is rather old by today's standards... it doesn't even have the P4 plug. But anyway reason im guessing its his PSU is because i had that same exact rig with no problems... but i had a 550W Enermax.
 
The 300W Antec should be enough, but the 9700 Pro seems to be draining enough to cause problems.
I would think that a "new" Antec 350Watt should solve the problems, but if you are worried,
I would look at either the 330watt or 380watt Truepower Antec cause it separates the rails and will actually
provide more to the devices since the 5 and 3volt rails aren't shared.
