In SR design a certain amount of dead time is usually necessary to prevent the FETs from cross-conduction. So in theory an SBR in parallel with the body-diode of freewheeling FET helps efficiency....

Or the opposite way, SBRs for rectification and FETs for freewheeling. For example, CoolerMaster Real Power Pro 1000W. This is "true semi-SR" too.

In a SR circuit there's a Dead Time in every cycle when neither of the SR-MOSFETs conduct. Normally the body-diode of the MOSFET, which is slow and has a relatively high forward voltage, conducts. A...

3 12V's and 5 grounds in total. All PSU makers make it this way. 8pin PEG has 2 extra grounds only to "tell" the video card "the PSU is powerful enough". Although rated at 75W in PCI-SIG specs, 6pin...

First, I believe the SG-850's PEG modular cable is compatible with Antec's TPN series, TPQ series and EA-750 Green's PEG modular cable. So if GI_Joe can find any cable it should work.
