Externally the OCZ ModXStream Pro is a fairly subdued semi-modular design that looks good. The unit has a nice finish, well sleeved cables, good quality modular cables, and a large overhead fan. However, once we open the unit we find that OCZ 700W ModXStream Pro looks very much like a cheap group regulated unit. This is further compounded by the fact that the unit has some questionable component selections in the mystery "Rec" capacitors. Good capacitors only add slightly to the total cost of a unit so why even something along the lines of Samxon or at the very least Teapo was excluded from this build is bewildering. Further, the unit only features a 3 year warranty and with questionable capacitors this is hardly reassuring. Also related here is the unit’s "documentation." The documentation that came with the unit is simply a waste of time. This fact is punctuated by the power distribution table at the back of the manual was never actually finished by whomever was annotating it. The only upside to all of this is most of the information about the unit is printed on the packaging, but still sans a correct power distribution table as these are genuinely useful. They are especially useful when units do not follow the ATX12v specification or EPS specification for 12v power distribution such as this unit.
