OCZ ModXStream 780w PSU review

Power output for the 3.3v and 5v lines was spot on with never more than a 0.01 volt deviation be that under load or at idle.  The 12 volt rails were also perfectly consistent with one another in regards to output with a twist.  They showed less than a 2% deviation but all read high.  The ASUS mainboard sensors showed the rails running at 12.64 volts.  That is just a hair over what is seen as an acceptable 5% variation.  We confirmed this with our multimeter and came away a bit less with 12.47 volts.  This was confusing because the 3.3 and 5v lines were spot on but each of the 12 volt rails was at the 5% over threshold.  I'm assuming this was intentionally engineered into the ModXStream to ensure you get plenty of juice but high readings always make me uneasy weather they are within spec or not.

Conclusion

Even with our high 12 volt readings, the OCZ ModXStream showed itself to deliver rock solid power under a variety of conditions with variation of less than 0.01 volts.  This is in no small part on account of the Active PFC that regulates power output to ensure stable delivery.  Its silent operation, clean aesthetically pleasing lines and pricing do even more to put lots of marks in the plus column.  As a matter of fact, the four points made for improvement needed on the OCZ ProXStream 1000 watt unit were all addressed to satisfaction with the ModXStream unit.  Obviously, OCZ does indeed listen to suggestions.

As with most things there are areas that got lost and could stand some improvement.  The biggest is the high 12 volt readings.  Yes they were right at the 5% over limit but as I said before, high always makes me nervous.  In regards to the Molex lines, four standard Molex connectors isn't enough.  An optical drive, case fan, large CPU fan and a CCFL will tap you out forcing you to create some elaborate daisy chains.  The last point is what's up with the 'Wonder Bra' 8 pin PCI-E connector that has two empty sockets?  No huge deal but just like that scene in Animal House, a surprise let down.

All things considered, it's hard not to recommend the OCZ 780 watt ModXStream power supply.  It has features and performance to spare and delivers these without lots of fan noise and more importantly does so with a three year warranty and a reasonable price tag.  The ModXStream in available now at NewEgg.  Thanks to OCZ Technology for sponsoring this review.
