Why not just stick with your integrated graphics?
If you want gaming you'll need a 5670 or something about that range, but that could be too much power draw.
I have 3 machines in my house that together wouldnt max out the PSU.
a reference 5570 has a TDP of 43w.
washoe what else is going in this rig?
Fine, let's add up some watts.
CPU 65w + VC 43w +25w mobo + 15w HDD + 10w optical + 3w ddr3 = 161w
Now let's take a 180w "lite-on" psu which, in all probability, does not advertize it's real wattage, but haow much power it grabs from the wall.
I would not put this one at a power efficiency above ~70% and, combined with the fact that psus loose their efficiency over time, it should be even less.
So those 180 "pretend watts" are actually ~130w (probably less)
Sorry, bucko.
you are risking damaging other components too. I have no doubt it will work for a while but you are really going to stress that cheap little psu. don't be surprised when you get a burning smell one day down the road.Thanks everyone for the input. I should have spent more time considering this when I got the system. I went ahead and got the 5570 without an extra power supply.
What is the biggest risk I'm taking in not upgrading the power supply? Just that the PSU will burn out... if so I just get another one. Or is there more at risk?

if not that should do it if its a worry
180w it too low for CPU and GPU and other stuff.
it doesnt have enough voltage either I bet.
Hi there,
I bought the exact system; planning to use it for school work, itunes and htpc . I plan on adding a single fan. Do you think the psu at 180w is reliable enough for this purpose? Or should I just upgrade the psu regardless?
Thanks!
