Will a CX430 v2 be powerful enough to supply an i7-3770k and HD 7850? I already ordered the CX430 v2 and I'm not sure if it'll be enough for these parts. I won't be doing any overclocking the parts start to become outdated, which is when I would get a new PSU. Also, I need suggestions for a good budget motherboard to go with this, preferably under $100 which seems like a bit of a stretch.

Is this for gaming? If so, get an i5 and a better gpu. This setup will only get medium-high settings in games while an i5 and a 7950 would be able to max anything. And no, it will not be enough power.

The i7 is on sale on microcenter for the same price as a 3570k, so I thought what the hell why not. And are you sure it can't power them?

The power consumption between the 3570k and 3770k is pretty similar, and people have used he CX430 v2 with the 3570k.

Its about the GPU power needs and not so much the CPU. If you want to game, and get the most for your money, pick a $100 z77 motherboard and get the $40 off deal through microcenter. Use the money to get a better GPU. You will want at least 500 watts for any GPU 7850 or higher. Return the cx430 and get a cx600.

Also, there is no noticeable difference in gaming at all between an i5 and a i7.

Can I get some input from some other users? It's not that I don't trust you, tiny voices, it's that I want more assurance that the PSU won't be enough.

CX430 should be able to handle a 3770k and 7850.

It might be good for a 7850 but I figured with your budget and an i7 you would want also a more powerful GPU.

Since that is a decent quality 32A single rail GPU, I think it will be fine. 7850 only draws like 130W max.

I don't know if I would use a 430W for overclocking the CPU very high, though. Do you already have the CX430? I think I'd spend a little extra and set yourself up right now. Why spend the money twice?

Here's a good quality 630W for $40 after rebate and discount code: http://www.newegg.com/Product/Product.aspx?Item=N82E168...

I have the 530W version of that and it's a great unit.

This would be a great budget board that allows overclocking: http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Eh... I'm not really sure I would bother with green supplies - they don't really save you energy in the long run. There's better power supplies you could go with.

I used an i3-2120 and a Radeon 5800 with the CX430 on my HTPC and the CX430 failed to boot up after like 6 attempts. I replaced it with the Seasonic 430W instead and it runs pretty flawlessly now.

So the CX430 arrived today, and I've decided on a 7850 and i5-3570k pairing. I've ordered the 3570k from Microcenter for $169.99, which I think is a great deal. I expect I won't be doing much overclocking due to PSU limitations?

you can get a combo deal on a motherboard with the 3570k at micro center.

OP, I am sure the Corsair will be fine.

These guys: OP, I am sure the Corsair will be fine.

Overclocking you still might be OK as long as you aren't going nuts, but you will be pushing a 430W a lot closer to the edge than you'd normally want to.

Sure they do. A standard power supply is like 70-75% efficient. So one that is 80plus throws away at least 10% less energy as heat, and also runs cooler. That means less cooling need for case and longer lasting power supply.

Aside from that, the Rosewill green are just a good solid power supply for a decent price. "Green" just means a basic 80Plus, not anything special.
