Video card/power supply

I bought a LG 19" monitor and wanted to increase the resolution to the 1440 x 900. But my computer won't go that high.(1152 x 884 24 bit) so I thought I would get a new video card but when installed the computer goes into sleep mode. I am running a ATX 100W power supply. I am thinking that that is the problem. Am supplying a link to the specs of my motherboard.

the new video card is ATI RAGE 128PRO 32MB PCI. I don't game, just wanted a better card for video, resolution, etc. The card says that it should have a 350W psu. But since I have a 'micro?' psu (size 2 1/2 x 5 x 4) which is hard to find. I think I found a 300W, but not sure if its the right one. http://www.911forpcs.com/hpposuse.html
My question to you is.... will a different power supply allow my computer to run that video card? and what max psu will my motherboard handle? Any suggestions to links on power supplies will be very grateful.

 

If the video card requires a power supply (PSU) rated at 350w minimum, then a 300w power supply is insufficient. The PSU you need must meet or exceed the card's required rating (350w or greater). The PSU should be an 'ATX' form factor. If by 'max' you are referring to PSU power capacity, there is none. However, unless you're planning on running many power hungry peripherals (this doesn't sound like you, based on your post) then having a 500w PSU is probably overkill. However, it won't hurt your computer if that's what you're worried about.

Look at PSUs rated at 350w or more:

Note the reviews for the pros and cons on each one.

Good luck!

 

If the card says you need a 350w PSU, then buy at least a 350w PSU. With prices now that shouldn't be a problem, just buy a good one.

And a PSU rated above your current will not harm the motherboard, its more like a speed limit than anything else. You can use less or up to the maximum rating.

 

Thanks for the links sent, but they aren't the right size. ie. micro.
I will keep searching. The info you mentioned is very helpful and I will not be afraid now of damaging anything in my computer. Any brands better than others?
