I have a custom PC with an Intel i7 3770k, Sabertooth Z77, 2x 8GB Corsair RAM, 2x 7200 RPM IDE HDD (300GB & 160GB; PATA to SATA converters), 1x WD Green SATA HDD (2TB), 1x Samsung 840 SSD (250GB), Zalman Z9 Plus with 6 120mm fans (2 LED) and a Hyper 212 Evo with 2 120mm fans in push pull. Currently I have one Asus GTX 660 (non-ti; GTX660-DC2O-2GD5) in it and it is running just fine with the PSU I have. When I first built this PC, I had no intention on using 2 fairly high end video cards in it. In fact I was planning on using the HD 4000 for the time being, and then the 660 was released and its price and performance made it irresistible. Newegg had a sale a few months after it was released and I got one for around $215 plus a free copy of Assassins Creed 3. It has been running strong and taking any new game I throw at it in high to ultra settings for the last 6 months. Then, as a regular newegg daily deals troll, I landed on the same exact make and model graphics card now only $168 after a $40 discount (off its release price of $250), a $20 promo code and a $20 mail in rebate. So naturally, it is on its way to me at the moment since it is the perfect card to pair with my current, identical one in SLI.

I am concerned that my 550w power supply may not be enough. I have done a few searches and have read of people asking if 650 to 750 was enough. I did go to the site below and entered all my PC's info. When factoring in my overclock of 4.5 GHz and the two GTX 660's in SLI, the fans, HDDs, RAM, etc., the PSU calculator said I needed at least 492w.

Am I going to experience sudden shutdowns or BSODs if my system draws too much power that the PSU can't handle? Will my PSU die an early death if it is being worked too hard with this setup. Or, is it adequate?
I have read other posts about testing the wattage of your PC using a kill-a-watt or a multi-meter. One method to find wattage is to find amps and volts then multiply those values. I have a multi-meter. Should I test the amps and volts? And where on the PC do you put the leads? I have read of other methods that use an extension cord in line with the PSU cord, but I'm not crazy enough to try that.
I know my motherboard and CPU setup allows for PCI-e 3.0 x16 with one card and x8 x8 with SLI. How much of a difference does if make if I am using a motherboard capable of x16 x16? I read that PCI-e 3.0 x8 is about the same as PCI-e 2.0 x16. Should I get a better motherboard or is the Sabertooth Z77 enough?
I also read that when you SLI two or more cards, the RAM is only used by one card?
Thanks, and sorry for the TL;DR-ness of my post. I appreciate any help.
