So what do we think of the Silent Pro M2 1500W? Without a doubt Cooler Master built a monster power supply. The difference in PCI connections from our 1200 watt power supply to this monster is staggering and worth the price of admission alone. If you are planning on running four video cards, your options are very limited. Normally the best option is to just run two power supplies. In this case Cooler Master has given another option. There is enough flexibility in its connections that you should be able to power both four video cards, and have enough left over for all of the various connections today’s high end motherboards require. If this power supply performs as well as promised, it will be a great addition to any monster build or test bench. Now our biggest dilemma is should we put it on our test bench or use it with the 16 core, quadfire monster project build we are about to start on. If you are considering this one, with an MSRP of $399, its a little higher priced than the only other 1500 watt PSU on newegg. But with a lot more connection possibilities and a quiet fan it is still a good buy.
