OCZ 780W ModXstream PSU


With modern PC's becoming more power hungry and PC builders becoming more demanding, the PSU arena is rapidly becoming more and more noticeable. The humble PSU, as it should always have been, is now in the forefront of the enthusiasts mind when considering a new PC build. No longer are people satisfied with dull steel cubes with a multicoloured rats nest emitting itself. OCZ, are the answer to many peoples prayers when it comes to stylish yet powerful PSU's and the 780w ModXstream is no different from previous incarnations. With 780w on tap, and a stable, quad rail setup rounded off with a stylish design it should come as no surprise that this PSU comes recommended by many sites. There are however a few little niggles that I would like to point out that others seem to have missed.
A 780w power supply should be enough to power all but the most obscenely hungry PC's, or so you would have thought. The one major fault I found with the OCZ 780w ModXstream is that there are only two 6 pin PCIe cables. While this might appear to be plenty for a single card setup, if your single card happens to require an 8pin PCIe cable then you are out of luck. Much so for anyone wishing to run an SLI/Crossfire rig with the latest generation of cards requiring 2 x 2(4) 6pin PCIe cables, never mind additional 8pin PCIe's. So the ModXstream PSU is severely limiting its target audience to someone who only intends on running a single mid-range card. The PSU is currently available for a bargain price of £77.49 at ARIA but I would be quick to snap this up as the average price on the net appears to be around the £95 mark which, it has to be said, that there are more powerful PSU's available with a greater amount of connectivity at that price point. However, with the £20 saving at Aria this PSU should be given serious consideration.  
The OCZ PSU is a very good, quiet and capable PSU in its own right. With a price revision matching that of Aria , I'm sure it will be very popular as it is possibly one of the best looking PSU's around at this moment in time, especially if you have a fondness for blue LED's! You may however wish to look elsewhere should you want a dual GPU setup which is perhaps the only fault I can level at the OCZ 780w ModXstream.
