What it’s all about

First let me be clear in saying that this is only a sneak peak at the Silent Pro M2 1500W. We don’t do full power supply reviews because we don’t have the equipment to benchmark the power supply to our high standards. What we are doing today is looking at the Silent Pro M2 1500W’s features, not its performance.

Having said that, my first impressions when taking the power supply out of the box, this thing is HUGE. Our 1200 watt power supplies aren’t small by any means, but as you can see by the distance between the edges of the fan to each end, this is much longer than the average power supply. Finding cases to fit the Silent Pro M2 1500W is going to be a little difficult, but to be fair if you need this power supply you will already be looking for a large case to fit your 3 to 4 video cards.

Much like a lot of the other power supplies on the market the Silent Pro M2 1500W uses a hybrid modular design meaning only some of the cables are modular. Normally this is just the 24 pin power connection and one or two 8 pin CPU power plugs. For the Silent Pro M2 1500W you actually have a large amount of non-modular cables.  On top of the 24 pin power connection you have two 8 pin CPU’s and a whopping three PCI Express cables. Each cable has one 8 pin along with an 8/6 pin daisy chained off of it. From a wiring perspective this design is great, you only have to run one wire per video card for its two connections, but if you needed two 6 pin plugs this isn’t going to work out for you. They are able to do this by running a larger gauge wire from the power supply to the 8 pin and then a standard gauge wire from the 8 pin to the 6/8 pin. The larger gauge wire helps carry twice the load.

Don’t worry though you have a few other connection possibilities, but everything else is modular meaning you won’t have to use them if you don’t need it. On the power supply itself you have six more six pin connections as well as five of their five pin plugs that power molex and SATA power. When digging into the collection of cables included with the Silent Pro M2 1500W we actually have four cables that plug into the 6 pin ports. Three of those cables are combination 8 pin + 6/8 pin cables and the fourth is a 6/8 + 6/8. So when you do the math this power supply has enough PCI connections hooked up at any one point to power six high end video cards. Of course even with 1500 watts, it wouldn't have the power to push anything beyond 6 x250 watts. What these extra connections help with (beyond your fourth card for SLI or crossfire) is the 6 pin power connections we have started to see pop up on high end motherboards.

We mentioned before the five accessory power plugs as well. Unlike the 6 pin plugs, the power supply only comes with the exact amount of cables to match the plugs provided. But you get a staggering amount of connections out of those 5 plugs. You have a total of x 12 SATA, x5 Molex and one 4 Pin Floppy. That should be more than enough to power anything any one rig will have, short of a 20+ hard drive file server.

As with previous Cooler Master Power supplies that we have had, all of the modular cables use a very thin and flexible cable design that we love when trying to hide cables. By laying each cable out flat they are able to make a cable that fits between the side panel of most cases and the motherboard tray much easier. This should be a requirement with EVERY power supply. They make life much easier. My only complaint is that there isn't a similar design to make the 24 pin cable a little easier to route.

After sorting through all of the cables we did find one more small adapter that was included with the Silent Pro M2 1500W. Cooler Master slipped in an 8 pin to four pin adapter just in case the motherboard you are using with this power supply only uses a 4 pin, or like a few boards we have seen, one 8 pin and one 4 pin. Because the 8 pin cables they have don’t split like on some other power supplies, this cable is very important.

Last but far from least, we have to look at the power supply’s power cable. Much like other 1200 watt power supplies, this monster requires a special cable design to prevent you from hooking up a cable that isn't large enough gauge to handle the power. This isn't an issue as long as you don’t lose the cable, but in my case, I have needed an extra a few times. I wish we could find this cable size more available for sale apart from these giant power supplies. It would make unhooking and hooking back up before and after LAN parties much easier.
