I recently asked if my 650W power supply would be enough to handle my planned upgrades, and I got the answer that it would, but it would be very close. That being said, I planned to buy an 850W 80+ Gold power supply because it was on sale for $5 more than a 750. Today, the promotions ended before I bought it, and there is a new one out for a 750W 80+ PLATINUM power supply, within $10 of each other. Which should I go with:
