OCZ StealthXStream 600 Watt PSU

Internals & Cables


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.




As you can see above, OCZ have done a pretty good job with the layout of the internal components. Within the components sit three aluminium heatsinks, to aid in the dissipation of heat. One of which is equipped with fins to increase surface area and therefore efficiency. In addition to the heatsinks we see a single aluminium plate which is acting as an extension to the finned heatsink.

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.


Pretty much all power supplies incorporate a fan to assist in the cooling process. A lot of higher performance units tend to use both an 80mm fan and a 120mm fan, however this tends to increase noise levels, or at least generate a slightly less pleasant pitch. The StealthXStream utilises a single 120mm fan, which should allow for a lower average RPM level, reducing the level of noise and pitch produced. The fan included within the casing of the PSU is clearly labeled as a Yate Loon S12SH-12, having run a quick google check I have found the following information:

Model - S12SH-12
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.

Molex Molex

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.

PCI-E connectors SATA connectors

24pin CPU connectors

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.

This is the PSU I use and its definatly the best one I have ever used.

Seriously, it is 99% silent.Quote
