Can I get some PSU recommendations up in here?

So I've been using this thing for the last 5+ years. For history, it ran an 8800GT and Athlon 64X2 for the first few years, then the 8800 died and I replaced it with a GT210 (the dark times...). That lasted until last year, when I built a new budget rig with a Pentium G630 and HD 6670, and it's been powering that ever since. Still hasn't given me any problems thus far.

But it has been a while, and it seems like I may have been lucky with mine (I certainly got lucky with the PCI-E and SATA cable count, since I had no idea to check for those when I bought it, and wound up with exactly as many as I've needed thus far) so I figure it might be about time to refresh it.

As far as future requirements, I don't figure I'd really ever go for more than the cheapest Core-i5 of whatever Gen is newest, a GTX 660/HD 7870 (or whatever will rank as their hierarchal equivalents in the future), and 4 SATA devices. No plans to fiddle with overclocking. SLI/Crossfire would be considerations for the future, but not necessarily for the PSU I'd be getting next.

Also, I am often quite the skinflint (which is why I cheaped out on my current PSU all those years ago) and will be taking suggestions into consideration for which ones I should be on the lookout for when Black Friday/Cyber Monday deals start to kick in. So there's that.

One final note, and it's the main reason I come asking for suggestions, is... you know those numbers on the side of the PSU? The one everyone says are important and should be payed attention to? With the voltage and amperage or whatever? Yeah. I have no idea what they mean or what numbers would be ideal. So I guess that's really why I come to you guys.

The primary factor in psu sizing is the graphics card.
Use this chart, and you will do fine:

But... do not go cheap on psu quality. A cheap psu will not give you what you paid for, and if it fails, can damage anything it is connected to.
Pick at least a tier 3 unit from this list:

As to the cpu, my rule of thumb for a balanced gamer is to budget 1/2 the cost of the graphics card for the cpu. The GTX660 and 7870 are $185 cards.
So, budget $90 or so for the cpu.
That would buy you a amd X4 750K or a FX-4130.
If you are more comfortable with Intel, a g3420 or i3-3240
If your games are multi core enabled(few are), prefer the amd...
The XFX 550W PSU is like $60 and should last a while. A very solid PSU built by Seasonic. As for the numbers, +12V gets the most talk about. -12V is deprecated. The chart really breaks down how many watts are allocated to each rail basically.

And a good formula to know: amps * volts = watts. But fair warning: don't believe everything you read off that chart. Always do research and find quality reviews. Some PSUs are not good and should be avoided. Some PSUs just don't hit the marketed numbers.

Otherwise, the faster intel cores would be better.
