Yes. I would be suprised if it couldn't. Maybe not much more than that, though.

I installed my 5850, the computer starts into windows fine, however I checked my voltage on HWMoniter and it's showing the +12V voltage as 1.70V, does this mean that this PSU is barely keeping up with the power draw? I haven't installed the ATI drivers yet because of this...

I don`t think you would be able to run your PC if the 12v is down to 1,70v.
This would mean that you g.card gets no power.
My 12v is down to 7,86v but 1,70v is a bug or wicked g.card that can stay alive with that.
And i don`t think it hurts to have the drivers installed. This will only help.

yeah I took out the card still getting only 1.70V must be a bug
post #25 of 27
software monitors tend to suck or be buggy. so I wouldn't worry too much about it.

if you have a multimeter, check the output using one of the molex connectors.

FYI, HWMonitor is showing me a 9.06v on the 12v line... I wouldn't worry.

My motherboard must have really good monitoring circuits, because all my stuff is right on the money.
Except my negative values, which I think aren't even put out by my PSU.
