OCZ StealthXStream 600 Watt PSU

To get a true feel of what you're getting for your money, each power supply that passes through the hands of Overclock3D is opened up and thoroughly examined. However as time goes on and technology improves, look and feel are becoming less of a reliable way to gauge the levels of performance likely to be seen from the unit. Nonetheless, there is still knowledge to be gained by opening it up and having a snoop.
Another thing you may notice is the white substance between and surrounding some of the electrical components. The 'goo' seems to be a rubberized silicone and I suspect acts as insulation. This is the first time I have personally witnessed this process, however, other PSU's passing through Overclock3D's review process have displayed this.
The overall setup inside is certainly very spacious, unlike the usual dense distribution seen in high output power supplies. While this should result in far better airflow, by assisting cooling and helping to maintain acceptable temperatures within the casing, this doesn't impact on the StealthXStream's small footprint.
A nice little 'extra' seen on some power supplies is the inclusion of an adjustable potentiometer. This component can usually be tweaked with a screwdriver to increase output on a certain rail, which can come in very handy when voltages start to deviate from ATX specifications.
Dimensions - 120x120x25
RPM - 2200
Voltage - 12v
Airflow - 88 CFM
Noise - 40 dB
Cables & Connectors
All the cables on the StealthXStream are sleeved with a nylon mesh from within the casing to the very ends of each cable where they are tied off with cable ties and sleeved with heat shrink tubing. Each end is tied off very tightly which does make bending the ends to fit sockets a bit awkward, but it does keep everything looking neat and tidy.
You can see above that the 5 molex connectors attached to the power supply are fitted with easy release grips which allow for easy removal from any device that may require them. You can also see the high standard of the cable braiding and sleeving method.
As for the remaining connectors, it's clear that OCZ have tried to cover all the bases without overcomplicating things. You have two PCI-E connectors, for SLI or Crossfire configurations, three SATA connectors, two P4-12v CPU connectors which can be used together to cope with the 8-pin ESP12v standard, a single floppy drive power connector and the usual 20+4 ATX connector.
The layout of the connectors is fairly efficient, with perhaps a little too much distance between SATA connectors for those into their cable tidying. The connectors are distributed between 6 main cables:
1. 20+4 ATX connector
2. P4-12v / ESP12v
3. 3 x SATA connectors
4. 3 x Molex connectors
5. 2 x molex + 1 floppy drive connector
6. 2 x PCI-E connectors
The molex layout is fairly standard and perfectly usable for those used to modular units.
