I'm upgrading my 2800+ Barton to a 3200+ Venice. My question is if the 300w power supply will be sufficient. I will be using an Radeon 9600 pro AGP at stock speeds, 1GB of Corsair RAM, one DVD burner, two S-ATA HDs and 4 80mm case fans. I will hardly ever be using this system for gaming and only moderately overclock the CPU as I already have a dual core notebook for gaming. The combined (3.3v + 12v rails) power of the PSU is 120W. Will this be enough to be stable? I had this PSU for over 6 months running on exactly the same config minus the new motherboard and CPU and it ran fine.
Thanks in advance.
P.S: I'm also looking for an m-ATX, socket 939, AGP mainboard for another computer.
you also need to take into account the quality of the PSU and its age. I would most likely takeout $30 for a decent PSU just to save hassle.
