150W Rackmount PSU enough for basic A64 spec?

I really wouldnt want to chance it.
Do you have the amps on the rails?
Should say on a label on the psu.

I doubt it - 150w is less than some PIIs used to run on.
Not worth the risk IMHO.

Tom you are such a risk-taker.
150w is such a small capacity... *bites nails* Only just more than half that 250w in the shuttles...

Your average PC barely consumes over 200watts at full load, so I should imagine 150watts to be absolutely fine.

Don't some of the mini-itx boards take A64's? I'm sure that they run on 80W and less power supplies.

With 1 hard disk, integrated low power graphics solution, and no overclocking it would be no problem at all. AMD64's are not that power hungry, 85-95W officalliy I believe but thats like 'worst case' processor at full load+
A high quality 150W PSU rated for continuous operation probably has some in reserve for transient peaks which are higher.

http://www.silentpcreview.com/article313-page5.html total system power used is ~100W at full load
So I guess a 150W PSU is enough providing the 12V is quite good, if it is an older PSU the focus might be on the 3.3V and 5V rail in which case the CPU might not get enough power from the 12V rail.

I am running a 3000+ venice, MSI K8NGM2-FID mobo with on board 6150 gfx, 4 x 256mb ram, 1 x 160gb HD and 2 x compro tv tuners.
Measuring power draw at the wall it idles at 68W and the highest load i have seen is around 110W, maybe a little less. Stressing everything to the max I can't see it being any higher than say 120W.
Don't forget that includes the PSU inefficiency. at low loads that probably accounts for 30% or more of the power draw at the wall. This means the PC itself probably never draws more than 80-90W even in the most extreme circumstances.
I'd say that a 150W PSU is enough assuming:
1. the psu actually provides it's rated 150W at higher temps (ie middle of summer)
2. It meets the 12v requirements.
