OCZ 780W ModXstream PSU

Packaging & Appearance

Packaging
 
I've always been a sucker for a nicely presented product and from the outset the OCZ didn't disappoint. A thick, glossy, cardboard box hosts the PSU with a clear, yet concise feature list, advertising the PSU's capabilities and benefits. I should, however, point out that the same packaging is also used with the much cheaper StealthXstream range of PSU's from the same company so while the packaging is good, for the price I would have liked something a little more 'special'.  
 
Front Back
 
Opening the box I was alarmed to find that the packaging is sparse to say the least. With little more than a layer of cheap bubble wrap protecting the PSU from damage (as well as the box itself), I would not be surprised to find that some PSU's might be damaged in transit. Styrofoam is pretty much standard packaging now among high-end PSU's and is a much more suitable method of protecting heavy items such as a PSU which also works to prevent the PSU from sliding around in the box. I was also mildly disappointed that there was no method of protecting the plastic Molex/SATA/PCIe connectors. Again, for the price of this PSU, I would have liked to have seen some form of pouch used, especially as this PSU is of modualr design. 
 
Inside Contents
 
Taking the PSU out of its box I would say that the PSU felt quite light in comparison to other power supplies in the same power range. 'Weight is a sign of reliability' so they say, so while I wouldn't exactly say the PSU is a lightweight, you certainly won't need your spinach to lift it.
 
 
Appearance
 
Measuring 150 x 140 x 86mm, the PSU should fit in all but the smallest of cases. The matt black finish on the outer EMI (Electro Magnetic Interference) shell is pretty resilient to scratches and should see the buyer through multiple builds without too much cosmetic damage. The most striking aspect of the PSU is of course the blue 120mm fan.
 
Outer Shell 1 Outer Shell 2
 
The underside of the casing has no ventilation which will aid the cooling properties of the fan as all the cool air will pass over the internal heatsinks and then be vented through the mesh panel on the units rear. It has to be said that whether the PSU is powered or not it certainly looks the business and despite the poor packaging reported earlier, reached OC3D in pristine condition.
 
Rear Front
 
The rear of the PSU is a black mesh affair allowing hot air to escape with the usual on/off power switch situated directly above the kettle lead. There are no diagnostic LED's on the PSU which would have been a nice addition but as the fan lights up it's not so much a problem.  
 
The sample we had did not have any labels identifying which cable went where and apart from the obvious, there was a little head scratching going on as to where the PCIe cable went being that there was 2 x 8 pin cables (PCIe + CPU) and only one 8 pin port. The instruction manual was of no help whatsoever with regards to connecting the PSU up so it was a case of praying I had them in the right slot (ahem!). This is not exactly what I would have expected on a £100 PSU from OCZ!
 
 
Cables & Connectivity
 
The PSU itself is not 100% modular, with the 20/24pin ATX, 6 pin PCIe and 4+4 CPU cable permanently attached - meaning that if you don't have any use for molex connections this will add to case clutter. However, most gamers/case modders will have some form of cold cathode, LED strip, extra fans that require powering so it is not so much a problem.

All the cables are professionally sleeved and securely heat-shrinked in black, making for a very good looking cable setup.
 
20+4pin CPU
 
The 20+4 ATX connector is of a very basic design and doesn't really work as it should. Rather than the 4 pins 'snapping' onto the 20pin connector you have to squeeze both sections together to fit them into the motherboard. I would like to see a simple little sliding mechanism by now as surely it cannot be too difficult to achieve. I cannot really mark the OCZ PSU down for this though as they are only following suit with other manufacturers but it is a missed opportunity nonetheless. The CPU connectors suffer the same fate as well. Along with the above a 6-pin PCIe and a molex cable complete the cabling that is permanently attached to the PSU.
 
Cables
 
The modular cables come neatly bundled with a piece of Velco preventing them from getting tangled during transit. The cable ends have solid black connectors with the usual snap/lock latches that should last the test of time and are also clearly labelled. The latching mechanism that, while simple, does the job perfectly, preventing any accidental removal of a cable from the PSU. Here is a list of the cables included :
 
- 1 x 4+4-pin CPU (2 Total)
- 1 x 6-pin PCI-E (2 Total)
- 2 x S-ATA (supporting 6 drives)
- 3 x Peripheral (supporting 6 devices) 
- 3 x Floppy
 
PCIe Molex
CPU 4+4 S-ATA
 
That pretty much covers the external aspects of the case and cabling so let's whip out the trusty screwdriver and take a peek at the ModXstream's guts....
