Unlike its rather flashier brethren, the OCZ ModXStream-Pro is a modest looking unit finished in a mottled metallic-grey paint job. That said it has got an enormous 130mm fan, which should help improve cooling while keeping noise down. In the box you also get a neat bag to store all the modular cables, which is a nice touch, as well as a mains power cable and four mounting screws.


We're disappointed to note this is another supply that has both four and eight-pin 12V cables permanently attached rather than a single 4+4 cable or modular cables. The rest of the modular system uses a rather simpler arrangement than most with just two eight-pin sockets for the graphics cables and four six-pin sockets for the other connections.


The PCI-E cables are just 48cm long and only one is finished in an 6+2 connector, though this latter point is forgiveable given this supplies 600W rating. The other cables consist of two 80cm ones with two Molex plugs along their length and a floppy drive connector on the end and that are 80cm long and have three SATA plugs. Overall these cables are on the short side, there's not too much choice and there could easily be a situation where you end up needing to use most of the modular cables even though you use only a few of the connectors, thus somewhat defeating the object of a modular system.


Luckily for the ModXStream-Pro 600W, there's one thing that saves it from being an also ran; it's the quietest PSU on test, both at idle (34dB) and under load (37dB). Combined with its reasonable price this makes for a decent choice for those only planning to use a single graphics card and that want the quietest system possible.

Verdict

It may not be perfect and certainly lacks the flair of some rivals, but given it's the quietest PSU on test and comes in at a reasonable price, we think this will be a good bet for those primarily concerned with keeping the noise of their PCs down.

Thanks for the review. Excellent.

I'm pretty sure Corsair PSUs are made by Seasonic so they will be decent. I've got plenty of Enermax, Seasonic and Antec ... more

I was using a Cooler Master eXtreme 430W, and it frigging surprised me.
I managed to use it to run a Q6600 and a GTS250 without a hitch.
