Would it be better if I posted all of my system's specs in order to find the most suitable PSU? More specifically to my cpu so we can see if the power it is receiving is insufficient?

It has multiple +12V rails that are only capable of providing 18A and 16A, meaning that after the graphics card has drawn its power from that rail (I'm assuming the maximum permissible through the PCI-e slot here, i.e. 75W), only 11.75A or 9.75A (141W or 117W) is available to power the rest of the motherboard. A typical motherboard pulls ~30W, and each RAM module ~5W. So that leaves just 101W or 77W for your CPU, which is probably insufficient. (I've used 2 sets of figures here, the first being for the 18A rail and the second for the 16A one. I've also assumed 2 RAM modules.)

I recommend a quality PSU of 650W, with a single +12V rail.
Thats exactly what i intended to say, but i was on my cell phone and unable to type so long!

You should do that, it will help a lot. Don't forget mention if you are looking forward to upgrade any other component (cpu, ram ...you know what i mean...), because this will also have to be considered, in order to prevent money wasting

It does have a conclusion! He now has to buy a PSU in order to use the system that he made, and thats what he came for

As for the nap, i totally agree... it's 1 am

Don't wanna be that person, but *she, lol.

So I've updated (to the best of my ability) my system specs, so you guys can click on them to assess what would be the best PSU to remedy this problem. If there is anything else I can do to further this, let me know.

I like to use 650w or greater in the newer home built computers.

You should edit the ram memory info- is it a single stick of 4 Gb or are there 2 sticks of 2 Gb. If you know @ wich frequency they are, it would be good to write that too. Use the PSU calculators to see how much are you using now and add ~200 W to be safe with the new graphics card.

Scrolling down, under Memory, is my ram. Friend gave that to me also.
I think I put in everything mostly correct in the calculator and got like 275, but I don't think that sounds right. Plus 200 would only be 475 w. I was just gonna go with a good 650 w or greater PSU, if anyone could point me in the direction of a good one.
