Not sure if I should go with either Gold or Platinum. Also, Corsair or CoolerMasteror Thermaltake? What size? My friend recommends me a 750 for future proofing. Btw, I hear Platinum is the best for energy savings. Which I have a tendancy to keep my electronics on all day, that's why I go with as much Energy efficient stuff as possible.
PSU Gold or Platinum?

I say go with Corsair out of those 3. Right now the difference between gold and platinum is very very small. So either is fine. I'd recommend a Rosewill Capstone 750w Gold, it's made from Seasonic, same people who make the best Corsair models, and it has a great price.
Rosewill is Super Flower not Seasonic. Avoid Coolermaster and Thermaltake. Great cases and cooling , crap power supplies.
If you just want a very high quality power supply go with the Seasonic X series. Also the Seasonic X is made for XFX as their 80 Plus Gold units and may be cheaper buying the XFX unit. Make no mistake it is a Seasonic X series just rebranded.
Al in all you can trust Corsair, Seasonic, PC Power and Cooling, XFX, Silverstone, Enermax, OCZ, Antec and the higher efficiency Rosewill units.
What size depends mostly on your graphics card. You can trust this list. They maintain the most comprehensive power supply database on the internet. Also they factor in all the "extra" you need with these recommendations

I'm getting the EVGA GTX 650 Ti BOOST. And I'd like to future proof myself with the PSU, which I am uneducated as to what plays an important role for future proofing for the psu size. I have acquired my Intel Core-i7 3770K already, if that plays an important role!?

As for the 80 plus power supplies certified badges in terms of energy saving, here are some stats:
So let's go with a 500W PSU and your system uses say 250W for 24 hours non-stop. Just upping the 450W that anort3 suggested to more rounded numbers for easier calculations. So anyway, your PSU will be at 50% load.
Regular (80 Plus): 939W
Bronze: 915W
Silver: 882W
Gold: 834W
Platinum: 810W
In Watts per hour:
Regular: 39.125W/h
Bronze: 38.125W/h
Silver: 36.75W/h
Gold: 34.75W/h
Platinum: 33.75W/h
So I pay about $0.22 per kilowatt. So if I left it on 24/7 for a whole year, I pay (in USD):
Regular: $75.45
Bronze: $73.52
Silver: $70.87
Gold: $67.01
Platinum: $65.08
So I saved a measly $2.00 in a month by switching from Gold to Platinum. If the difference in the PSU price is even $50, I'd need to keep the Platinum running for 25 months at 24/7 just to break even.
So don't even bother. Even from Bronze to Silver or Gold is pointless in terms of energy saving.
Edit: oops bad decimal place

K. But that's only the power coming from the GPU. Doesn't the CPU and every other component hooked up to the PSU consume wattage? So like you said, the GPU does 450. So I would need more than a 450 PSU, due to the other components, wouldn't I? Like, quite a bit more, especially if I'm future proofing. And I'd never add a 2nd card, I'd swap it out & pay the difference for a newer model, cheaper imo & way less hassle.

No; that's 450W total. The recommended minimum for your system is 400W according to NVIDIA. Your GPU will take up at most 110W, which means you'll need a +12V rail with at least 10 amps current rating and of course one 6-pin power connector.
^ This. All recommendations include your entire system. No one would make a list that only included power needed for a graphics card alone. It would not be a very useful list. The graphics card is the single largest power draw in a computer though. So what power supply you need is basically determined by what GPU you have.
Ok. Thanks. And so far, I've found building my 1st PC, I have to either ask or figure things out, so for them to make a list, I was assuming that was only for the GPU. I now know. Thanks. But my big concern is I'd like to future proof myself, which I'll prob. swap out the GPU once every 2 to 3 years. So, I'd like to know what exact size woulddo me good for future proofing. If what they recommend will stay roughly around that number for the next few gen series of Nvidia cards, then I'll gladly find a 500 for a reasonable price.
So would I play it safe by going with an 80 plus or bronze? I was told the different colors, are the different types of metals used inside the PSU, which the higher the color, the longer & more robust it will last. Idk if that's true or not.

I would say 650W maybe. It's hard to predict. We are not psychics. Technology continues to move at a very rapid pace.
The difference between the PSU efficiency ratings are better parts, fan noise (or lack of noise) from the PSU fan, the size of the fan, the number of ball bearings, etc. Some of the Gold PSU fans don't even start to spin until it gets to about 40%+ load.

Definitely not true.
Understanding the 80 Plus Certification
http://www.hardwaresecrets.com/article/Understanding-the-80-Plus-Certification/742
Thx for the site. So from reading, what I'm seeing, is that my best bet would be to get a PSU double the size of what my PC puts out, which by the list mentioned above said w/my GPU, will be approx. 450. So I should go w/a 850-1,000 to get the 80 plus energy efficient capabilities it pushes out of it. It states the PSU works best energy saving wise, when the PSU is at half the load, due to around 50% is where it performs/saves best at. Am I right? Hoping I read that correctly.
