Providing an indication of segment performance, we have chosen to compare the Straight Power 11 against two recently reviewed supplies featuring the same kind of wattage. be quiet!'s own Pure Power 10 600W and the Cooler Master MasterWatt 650W are both cheaper but have bigger capacities.
That said, voltage regulation on the 12V rail is very solid from all concerned, and we see the SP11 eke out very small leads on the the full- and cross-loads tests. All good thus far.
