This was my old PSU that died.

That is complete and utter trash, it's not a 500W PSU, ripple goes out of spec once you pass ~300W(with high minor rail loads, so the usable 12v power is even less than that).

Phaedrus' suggestion is very good, that's A Lot of PSU for 25$.

Thanks a lot guys. I just wanted to make sure that whatever I buy will handle a 7850 or 7950 gpu in a few months. And the misses will love the price. Seems I might be up and running sooner than I think. I'm also wondering what you guys are looking at to tell whether it's trash or not...

For your PC,a quality 500W unit is more than enough,even with OC'd components.Modular cables,well,only you can answer that.Do you care about clean looking interiors,and cable management?
If yes,go with modular PSU.If not,go with non-modular PSU,they're generally cheaper...

Also,your RAM sticks are budget ones,they aren't performance memory,intended for OC'ing,so that's probably the case why you were crashing.Don't bother with RAM OC,it won't give you any "real world" performance improvement...

Specs, platform, competent reviews, etc

I wouldn't recommend CX430 V2 for overclocked Phenom II X4 and (overclocked) 7950, though in normal usage it would still be okay, if on the higher side. Your current 5770 or a 7850 is a different matter. Or if you upgrade 7950 and CPU to Ivy Bridge or later, that wouldn't draw as much power as Phenom II X4 and 7950.

Another option, with 72W more on the +12V rail and of overall slightly higher quality anyway, is the Antec Neo Eco 450C, also selling pretty cheap ($35 without any rebate):

Maybe grab something else you need while you're at it, to get to $50 for free shipping.

Memory overclocking will net you not noticeable performance gains. Period. It'll all be benchmarks for the most part.
You can't overclock the memory without voltage crashes because memory is the #1 cause of instability when overclocking.

Your power supply does need to be replaced by not for the reason you mentioned before.
I recommend looking up deals for power supplies on slickdeals and then looking up reviews on those deals which are rated well to double verify that the innards of that unit are indeed good.

So you would recommend this for an overclocked Phenom II x4 965, as well with a 7850 or 7950. I never have really overclocked my graphics card and don't really plan to. But overclocking my processor is a different story. I just want to know that the +12v rail can handle it a cpu overclock. Also, my Phenom II x4 965 is the 125W version.

If you can afford it, I'd recommend it over the CX430 V2 for any situation (though don't get me wrong, it's not really that much better). It really depends on how you value the rebate on the CX V2 I guess.

The only concern with power I had was with CX430 V2, OC Phenom II X4, and OC 7950. All other combinations are okay with CX430 V2. 7850 draws about the same amount of power as 5770, which is less.

OC Phenom II X4 and stock 7950 should be okay, particularly outside of worst-case-scenario stress testing, but I'd still prefer something a little stronger on +12V than the CX430 V2 for that. Like I said, despite the "20W" difference between that and the Neo Eco 450C, the Neo Eco is rated for 72W more on +12V.
