this is a well made psu from Cooler Master with a lot of connectors, long cables for full tower cases overall this is a good psu for modding I suggest this if you are a modder, cables are really easy to modify.
Runs cool and is very quite I barely hear the psu running :).
I receive the 850 watts version instead of 1k. Amazon responded really fast with the return, I'm in love with amazon :) your costumer service is excellent.

This PSU powers:
AMD Phenom II 940 deneb 3.0 Ghz OC to 3.8
8 Gigs of ram
80 Gigs x 4 HDD
4 Fans with LED's
X-fi xtreme music
HIS ATI Radeon 5850 x2

Unlike some of the other reviewers said, I received the 1000W model which I ordered. If there was a problem, it has been solved. This power supply is modular except for the 24pin and 4/8pin power, and the modular cables are flat, which helps with cable management. This is powering my build comprised of the i7-930 overclocked to 4.0GHz, 6GB of 1600MHz RAM, an HD 5850, 6 HDDs, 4 case fans, and 2 Scythe fans for my Corsair H50 cooler.

This component is the quietest in the whole setup! And I know it will handle the Crossfire setup I'm eventually installing. The price is nice for the wattage, and it is efficient to boot. It has no LED lights on it, which works out perfectly as I am too old to want a light show in my case. The only problem I had was with registering the product, as Cooler Master's site is hard to navigate. The registration page will come up with a Google search.

My system runs well with this power supply (the 850 watt version). Here's a list of pro's and con's about it.

-The power output rating on this power supply is accurate, meaning it does provide as much power as it says it does.
-It stays very cool and quiet. In fact, it stays so quiet that I've had to check a few times to see if the fan was still spinning (and yes, it was running each time).
-It has plenty of power connectors, as well as different connectors on different wires. For instance, one of the SATA cables has only 2 connectors, the second one has 3 connectors, and the third one has 4 connectors. Use this feature wisely to give the case the best cable management.
-It is heavy, showing that it is made with good parts. My experience shows that the heavier the PSU, the better the quality.
-The 8 pin +12 volt CPU connector (it has 2 of those, totalling 16 pins) is well long enough to reach from the bottom of my Cooler Master Elite 430 case to the top of the motherboard, routing the cable around the motherboard so it is out of the way.

-The cooling was NOT what I was expecting to get. The page shows some finger-style coolers for the MOSFET's and diodes, but the coolers in the PSU that I received are the standard vertical fin-type. I hope that it can stay cool enough with those.
-The size is different than what was stated. Amazon said that the PSU was only 5.5 inches long (which is what I needed), but in reality, the unit is 6.5 inches long. If you have the same case as I do, you know how much of a pain this is. There is a 120mm fan that fits right next to the PSU on the bottom of the case. I had to remove this because the PSU's length was listed wrong.

Ordinarily I'd be giving this five stars. It works perfectly and is too quiet to be heard over other things in my lounge.

So what's the problem?

I bought this with a Cooler Master HAF 932 case which accommodates this PSU perfectly... at the bottom. Great place for a heavy PSU. Unfortunately the cables are designed for a top mounting location. They expect the first drive to be at the top and the power to daisy chain down. Well these cables won't reach round the back (where the wiring belongs on this case) and then out to the top drive bay. They will reach the bottom drive, but then either you can't connect the others or you have to twist the cable round so it can hook in upside down. That leaves the rest of the connectors hanging down and that's no good for powering the other drives. So now what? Well fortunately people make extensions and converters from standard cables, so I was able to pick up power from a 4 pin Molex (old style drive connector) and use that to power my two DVD drives.

This is a very nice power supply, I don't really need 850W of power, but the reviews, build quality, and modular design were sellers. The fan is ultra-quiet; even with the case open it's just about impossible to hear running. The cost of this power supply compared to some other options makes it a good deal - it was less expensive than several other options.

If I had to offer a downside, I'd say the "flat cables" Cooler Master makes a big deal about are just OK. First, the built-in non-modular cables are round, only the modular cables are flat. Second, the purported benefit of the flat cables is that air will flow around them more easily - I guess if air is blowing directly at the narrow edge and the cable is held straight, this would be true. In a real-life case the cables bend and twist and there is no way to aim keep the flat edge of the cable directly in line with the airflow. The flat cables are also more difficult to tie back than round sheathed cables, and unless done correctly it's possible to get several of the flat cables lined up along their long side significantly restricting airflow - bottom line for me is that after several builds, I'd much prefer the rounded cables.
