Quick question about a GTX 1060 with a CX430 power supply

Thanks guys. I don't really have many components other than a cdrom drive and 2 hard drives. It turns out this card has double the power needs as my old GTX 750 ti but i'm glad i'm still in range. and I'm moving out of the stone age graphics wise! Thanks again.

You'll have a CPU, which, other than the GPU, is likely the biggest power draw.
Even though the CX430 *can* do it, I wouldn't expect it to last forever......and I'd definitely start budgeting for a replacement PSU sooner than later if I were you.

The older CX model PSUs aren't the greatest quality, and generally either fail early on, or you get a year or two out of them (not saying they can't last longer, just generally speaking).
The CX lineup were built down to the cheap pricepoint, to fill a need in the market - but they were never intended to last for the same length of time that could be expected from Corsairs RM, TX, RMi lineups.
The CX430 has a 3 year warranty.
Quality PSU offerings in the market have 7-10 year warranties.
You have a TX gathering dust? I'd be more inclined to use that (although there are variants there too).
You're not really saving any power with a 430 vs a 600/650 - you are, it's just negligible for most folks.
Assuming your max power draw is around 300W total for the system.
A CX430 80+ bronze would be running around 70% load on the PSU - so with 80+ Bronze spec, should be 85% efficient.
That would mean the CX430 would be drawing approx 353W from the wall to power the 300W rig.
A TX650 (also 80+ Bronze IIRC) would be running around 45% load on the PSU so, with the Bronze spec, would be either 82% or 85% efficient.
At 82% efficient, it's pulling 366W from the wall
At 85% efficient, it's pulling the same 353W from the wall that the CX430 would be.
Worst-case, there's a 7W different (again, max load - so would be even less in "real world" use cases).
Let's assume 24/7 usage at max load.
7W x 24Hr x 365 days
= 61,320Wh
/1000 = 61 KWh
Average US homes pay somewhere between $0.10 and $0.20 per KWh IIRC.
So, over the course of a year, absolute worst case, the difference between the two PSUs would increase your electricity bill by $12.20..... or $1 per month*.
*Remember, that's 24/7 use @ 100% load. Real world usage, I'd expect your annual increase in power consumption (and therefore, cost) to be in the <$5 range.
