300W PSU, 350W GPU. Is this safe?

I have a 300W PSU, & I've found an old 350W Graphics card I want to buy, as it supports a few extra monitors. Would using it damage my PSU, graphics card, or anything else? I won't be running anything graphically intensive on it.
Also, as a sidenote, does the motherboard or bios limit the number of monitors I can have?

My pc spec:
Intel pentium dual core CPU E2140 1.6GHz
Foxconn 45GM/CM motherboard
2Gb RAM

Thanks in advance, & please let me know if any extra info is needed.

What video card? You mean 35w, no?

Sorry, I wasn't very clear there. 350W is the recommended PSU power for it, not the power it uses.

get an radeon 5450 for 2 monitors
this is old gpu
btw it is very expensive nfor an extra 10 you can get 5450
it will hardly put pressure on your PSU since is a 19w TDP graphic card

The Quadro4 NVS 400 gets all of its power through the PCI slot so it will work fine.

Doesn't that still come from the PSU though?

It might be fine but do you want to take the risk for your entire system. Spend a bit on higher wattage PSU from Corsair, Antec, Seasonic of XFX.

Yes but it doesn't require the use of any PCIe supplementary power connectors.

The power consumption of that card is very low since it is passively cooled and uses very small GPU heatsinks..

It draws most of its power from the +5V and +3.3V rails because of its old design.

Oh, right.

Thank you everyone for the advice; I'll get it & see if it works.
