You asked about "non titantiums", so that's what I'm refering to, it applies to Titantiums aswell though just to a lesser extent.
When you say 'not pretty', i am assuming rather than the peak 90% say efficiency its a more modest 80%..not 50%..ie not terrible?
No no sub 80%, mid 70s for an example that would effect my setup, it can be sub 70% in the more extreme cases. It's something you get with all PSUs though, I'm not knocking SF. The titanium level takes away much of the pain but you still need to be carefull not to overspec. Which is why I say going overkill on a PSU isn't advisable if you've got an eye on efficiency.
When you say overspeccing is a nono for efficiency...i presume you dont mean titanium psus...i presume thats the whole point..ie a titanium psu efficiently deljvers power acrross the widest load spectrum.
Overspeccing refers to both wattage and efficiency rating, you can overspec with Titanium aswell although it has less of a negative impact because of the extra 10% requirement. You have to consider both wattage and efficiency rating. In a system that doesn't use a lot of power or a system that is idle most of the time, a low watt low efficiency rated PSU is more efficient than a high watt high efficiency rated PSU.
It's a ballance between wattage and efficiency rating, knowing the individual system and it's usage pattern is key. Like I say Titanium makes that decition easyer but it still needs some thought if your going to reap the maximum amount of benefit.
At one point last year i could have sworn their whole titanium range was on their website....
Wouldn't supprise me, there have been at least 3 false starts, I've had a thread open in the product suggestion forum since may last year.
These will be worth the wait I am sure, but what a wait. In hindsight I'd of bought something esle, waited to long to give in now though.
