x800 pro power usage

[GreenPlymouth]

Do you guys think a 300W 15A@+12v PSU is enough to power the x800 pro PCI-E?

I've got one dvd drive, 1 hd, a capture card (pci) 56k modem and 3-5 usb devices.

How will i know will it run without enough power even at Stock settings?
The manual says at least 350 but with a number of internal components?

Thanks

I would say that PSU would be lacking for that card.

If you can afford a new card, surely you can afford a minor PSU upgrade, why risk potentially damaging your components with subpar power?

the wattage is less important than amperage. what brand power supply is it?

I can say this is a fact since I personally know many people with 6800GTs running on 250W Sparkle power supplies.

certain rails handle various tasks while others handle other tasks.

by the way, if you want a cheap power supply that can handle that vid card with no worries, you can get a $21.99 Fortron 300W. it has awesome power at that price

This is my current PSU http://www.power-on.com/atx12vem300bt.html#spec

are the dc outputs good enough?

it's horrible. getting a better power supply with better rails and better efficiency will not only give your systems more juice, you'll end up saving electricity over time. higher efficiency means that more electricity is converted to DC current rather then heat. Anyways, it's not good to run a psu near it's peak capability. the more and longer you run a psu at, for example, 100% load, the shorter it's life will be.
