Need a bigger power supply for my SB51G

[ultimatebob]

I recently upgraded my Shuttle SB51G with an ATI Allinwonder 9800 Pro, but it seems that the little power supply in there isn't enough to handle the load.

The video card works great when I'm just surfing the web or playing games, but when I turn on the TV tuner to watch or record something for more than 5 minutes, the video card seems to shut itself down. I get a blank display and a hung computer, and have to hard power down the system to recover.

From what I was able to found online, it seems that the Allinwonder requires a 300 watt power supply, and that this is a common problem with older Shuttle XPC's. Oops.

I can't seem to find any 300W Shuttle power supplies available for purchase online, but I was able to find this 250W upgrade available:

I'm not sure if the extra 50 watts will be enough, though, and I'd rather get a 300 Watt model if possible. Does anyone know if such an item is available, and where I can get it?

I've got an SB61G2, which came with a 200W PSU.

I've got a P4-2.4C and had a 9500 Pro, and when I OCed the CPU, I had major stability problems... even at stock speeds, I'd get occasional issues, especially if I was doing a lot of CD-burning.

I upgraded to the 250W "SilentX" PSU a while ago, and now I run the P4 at 2.96GHz with no problems, and have an X800Pro at 525/1100... so I'd say the extra 50W might go a lot further than you'd think.

I've also heard great things about the SilentX power supply. I'm seriously contemplating, as I've always had stability issues with my Radeon 9700 Pro and my Barton 2800+.

Is it actually any quieter Rolphus? I've heard that it is noticeably so, but I'm wondering just how much.
