It will support the card but the issue is the power supply. I don't trust that and would rather have it replaced with a 450-550W psu from seasonic, corsair or antec

It has done great so far.

And the card is PCIe 3.0, but my mothetboard is PCIe 2.0, the card will still work right?

Yes it will work. PCIe is backwards and forward compatible

It probably runs great before because you've never taxed it before. I doubt that power supply could get anywhere near 500W (maybe 300W at best). Once you add your video card, you'll face more issues that aren't worth it

There always seems to be a decent sub-$30 deal on either Antec or Corsair PS's. Why take a chance on a no-namer just to save a couple bucks? A power supply is the number 1 part you shouldn't cheap out on

No, don't get any no name psu. Get what we suggested (corsair, antec, seasonic, xfx, etc...) in the 450W-550W range. The antec VP-450 is cheap (check newegg) if you aren't willing to spend much.

Try something like this.

http://pcpartpicker.com/part/antec-power-supply-vp450

The Antec VP-450 is a modern psu that uses a forward design.
Each rail can pull up to 186w and the radeon hd 7850 pulls 150w.

It can actually pull 550w with lower efficiency.
Its efficiency is about 85% but it doesn't get that rating because it does not have an Active PFC.

I think you said that wrong. A power supply is the number one thing you SHOULDN'T cheap out on.

BTW, a CX430 or a CX500 both are good power supplies and should run a 7850 with ease. As long as it has 30+ amps on the 12V rail, and its a respectable brand, its fine. A CX500 would definitely give you a bit more room for overclocking.

It just seemed he was looking for a super cheap psu and the only psu I'd recommend that goes below $40 is the Antec VP series.

I don't like Antec PSU's for the fact that most of them use two rails, you have to be careful that you don't overload one rail. It also only has 18 amps on each rail, which is something I don't like.

The CX 430 is essentially the VP450, except having a single 32 amp rail. Its really your choice, I just don't like dual rail PSU's.
