Externally the new Silverstone Strider Platinum ST1200-PT is identical to the 1000W model, sharing the same 80 Plus Platinum rating as well as a fan which does not start to spin until the PSU hits 40% load.  The internals are somewhat different, as this PSU can deliver up to 100A on the 12V line and do it without any issues as you can see in [H]ard|OCP's review.  Indeed the only drawback to this PSU is one it shares with others from SilverStone; the price is on the high side compared to the competition.  Then again the quality also surpasses many other PSUs in the same class, so perhaps the premium price is worth it for you?

"SilverStone comes to us with huge Platinum efficiency power with its Strider PSU rated for 1200 watts of constant power delivery. The PSU also sports a beefy feature set to go along with being able to support even the healthiest enthusiast computer build. Fanless modes below 40% power, dust filtering, and 16 sets of SATA connectors lead the list."
