OCZ EliteXStream 800W


1. Introduction

Today we have the chance to take a look to another member of the OCZ family of PSU's. The new OCZ EliteXStreaam series of power supplies is designed for high-powered gaming systems and workstations. We have in our hands the new OCZ EliteXStream 800W PSU, rated at 800 Watt.

 

The EliteXStream products are designed for optimum power distribution to all components by utilizing the highly efficient "single +12V rail" design. This approach to +12V rail design ends the need to budget power "across the rails" as is the case with the less effective multi-rail design found in the vast majority of high-performance PSUs on the market today.

OCZ claims that the PSU provides sufficient and stable power for all high-end components including multiple GPUs. Each EXS model is certified under the 80+ Certified program so they run cool and save on utility power.

The EliteXStream 800W delivers up continuous power through a complete array of connectors including four 8 pin (6+2) PCI-E and 17 drive connectors, while it is kept cool with a large 120mm fan. The ATX power supply is backed by a 5-year warranty and technical support from OCZ.

2. Package

The retail package of the 800W Power Supply model is can be found in various online stores for $153.95 - $195.00. Of course retail price can differ depending your local region and VAT.

The PSU is well packaged into the retail box, which should look familiar to all you that already own an OCZ PSU.

 

The PSU itself is is typically sized for the ATX v2.2 category (150 x 160 x 86mm). The 120mm rotating fan at the top is also very quiet.

The power supply has a matte black smooth finish and adds points to the overall look and design. The PSU edges are not sharp, so you can handle it without any worries. This PSU is not modular, like other OCZ Technology models. While solid wiring does not allow connection failures, it may occupy more space inside your PC case as well as some extra effort to keep the wires tide.

The rear of the OCZ PUS has a honeycomb design, that helps lower PSU's internal temperature.

The EliteXStream series are different than previous models. Instead of having four +12V rails, we find only a single +12V rail rated at 0~62Amps. Using a single rail means that the power is directly applied to the connected PC components using a simpler circuit design, compared to the four rail design. Of course, high quality components are also required in the internal of the PSU in order to offer stability under heavy loads.

Each of the +3.3V rails support up to 25A while the +5V rails offer a maximum of 30A, translated to an overall wattage of 180W - enough for the needs of the majority of SLI and Crossfire configurations.

Another neat feature is that this product has really long cables! The main power supply, the PCI Express and +12V cables have a length of 60cm, while the IDE and SATA cables are almost three times longer! So no worries in case you have a big sized case.

In addition, the PCI-E cables are labeled for easy installation and the main 20+4 and 4+4 connectors are also joined. We would like IDE cables to follow the molex connector design, making it easier to unplug them.


3. Tests

Which factors contribute to a quality power supply unit? Well, it should be able to perform as rated even under heavy loads and of course, it should offer reliability in time.

Though our measuring equipment is yet upgraded in order to offer hardware measurements for the provided outputs of the PSU, we have to compromise with simpler testing procedures, which however may lack accuracy.

We tried to overload our test PC with extensive CPU+3D usage via 3D Mark Vantage and PC Mark Vantage. On the hardware side, the PC configuration was as follows:

All PSU ratings were monitored with Everest Ultimate Edition v3.0. The following table lists the industry wide specifications for DC Output Voltage Regulation.

 

After running both benchmarks, the monitored outputs showed us how much stress the PSU has taken. A summary of the results can be found at the following table:

Minimum
Maximum
Average
+3.3 V
V
3,25
3,26
3,25
+5 V
V
4,89
4,91
4,90
+12 V
V
12,22
12,26
12,24

The results look very good. All ratings are within the standard range, while even at full load, the voltage only changes by 0.01~0.04V under a dual VGA setup.

In addition, the 120mm fan does not produce any noise even at full rotation speeds.


4. Conclusion

The latest EliteXStream series from OCZ Technology has a different internal design, compared with other families of PSUs such as the well known ModXStream series. The PSU's single rail design handled without any problems dual SLI configurations and as OCZ advertises, it can also sufficiently power Quad SLI configurations. Adding more devices, like HDD, optical storage devices, etc.. should cause no problem to this product. We liked the fact that its cables are long and that the included fan doesn't product any noise. The 80+ standard certification is welcomed and the 5 years of PowerSwap replacement program warranty, gives you no more endless return-for-repair loops!

Overall, the EliteXStream 800W product kept its promises and we cannot find any serious drawbacks. If you need a new PSU for your overloaded game PC, you'd better start putting some money aside ($153.95 - $195.00) and head on over your local store.
