No VGA Signal, New Motherboard

[ericvon]

So I just got an msi- 880gma-e45 motherboard, and an AMD 1090t hexacore, 4GB OCZ ddr3 ram.
My computer starts up, but has no VGA Signal. I tried removing everything but a stick of ram, the processor, and the monitor.
I swapped everything into my old computer. The power supply is only 250W.
What should I do to get the monitor working? The monitor worked with my old motherboard without any problems.

I could be wrong but i have my doubts about a 250W psu being capable of powering a set-up like that.
This pretty much spells it out.

You need a new psu!

Thank you Davcon, that chart made sense. So what watt psu should I get then? I'm thinking of getting this one: http://cgi.ebay.com/450Watt-Micro-ATX-Power-Supply-Provides-more-than-400W-/220631321090?pt=PCA_UPS&hash=item335ea6ca02#shId

Should it work? It's 450W

You have very good components i would spend at least $60-80 dollars on a high quality and well reviewed power supply.
The psu is the wrong area to skimp on when it comes to your rig.It's the foundation since your components require clean/efficient power to run properly.
Low cost units like the one you posted will fail and take other components with it like your mobo.
The minimum power supply would be a 500W imo.
Here's a some good quality units.
