Theres more to look at then just total amp rating on any one rail. That sparkle has 36a on +12 yes and the OCZ has 33a. However, that 36a rating is at 25c and will not be that way at normal load temps of 40c. The sparkle DOES NOT have dedicated sata lines, OCZ does
. The sparkle does NOT have dedicated vga power lines, the OCZ does AND with RFI filters
. The Sparkle does not have ANY sleaving nor does it have any Shielded power cables , the OCZ does
. The sparkle does NOT have any adjustable pots, the OCZ has 3 and they are accessible without taking the PSU box apart
For quality of the PSU, its right up there with the PCp&C turbo 510 atx series.
