SilverStone ZM1200M 1200W ATX 12V 2.3 & EPS 12V SLI Ready CrossFire Ready Modular Active PFC Power Supply

Pros: Upgraded from PCP&C cross fire 750. Was loading down 12v rail with dual 3870x2 to 11.82 well with in spec but... This BIG PSU loaded with 2 3870x2, Q6600 @ 4G 12v rail is solid 12.01. Now dual 4870X2; Q9550 @ 4GHz under water, 4 WDADF 150s RAID 0; 12 high RPM 120mm fans this PSU is a beast and never flinches no matter what I throw at it. Love the cables sleaving, and the modular design, and I did unplug one cable that was not neaded. Great finish, nice paint and loks awesome too, very heavy, great PSU and will last me a while.

Cons: Big, long and did not fit in my Lian Li PC201B and I had to add an extention to bolt it in. The flip side was pulling one of the brackets and the fan for the PSU bay in the case. That worked but I did not like it, and this is better, but it does hang out the back a bit. The PCIe cables could be longer, as the top GPU is a strech for the PCIe power cables, and the mechanism for the 6 to 8 pin is weak and could be more solid, like the 20 to 24 pin main ATX conector.

Overall Review: Q9550 @ 4GHz; dual 4870x2; 4x1G dominators; 4 WDADF RAID 0; LIan Li PC 201B... lots more

Pros: This is a true, industrial grade, high performance power supply. Constructed using top-grade Hitachi and Nippon Chemi-Con capacitors and high-end solid state devices throughout. A true 12 volt regulated design with the option of six separate 12volt rails or combining them into a single-rail configuration with the 5 volt and 3.3 volt rails derived with separate DC-DC converter/regulators. Modular cabling allows using only the necessary cables in a particular setup, keeping case clutter to a minimum. Modular cabling might be a 'con' for some, but the unit uses additional, external sensing for the 5 and 3.3 volt rails which would be the most affected by any contact resistance that might arise from modular cabling connectors. This sensing compensates for any voltage drop across the connectors.

Cons: Uses a single 80mm fan for cooling. At nominal power draw the fan stays fairly quiet, but at upper mid and high output the fan accelerates to full speed becoming rather loud. Given the type of PC this supply is meant for (servers, extreme gaming rigs, high-end workstations), being quiet is not the highest priority. Could use more drive power connectors. I'm using this supply in a file/media server containing 16 HDDs with the option of several more, and the 6 SATA/6 4-pin Molex drive power connectors is insufficient, needing additional taps. Using fabricated drive power splitters increases the chance of faulty connections. Master power switch feels flimsy and undersized for this power level.

Overall Review: Though this might be overkill for all but the most extreme PC build, this power supply is tough to beat for efficiency, design and quality. Silverstone quality is top notch.

Pros: This is my second Silverstone Zeus power supply. The first was a 650 which didn't quite have enough volts for my SLI setup with 10 hard drives. I bought this one to replace it and could not be happier with the modular design and great power.

Cons: None, this is the best Power Supply company out there.

Overall Review: Get one, you won't regret it.

Pros: Running 3x GTX285 Black Editions, 1x 9800GT (physics), 12GB DDR3, i7 920 @ 4GHZ, CoolerMaster V10 TEC Cooler, 4 HDD's, 4 high-power fans and still has power to spare. Running in single-rail mode. This does NOT void the warranty by-the-way. 100% modular design. Quiet despite the 80mm fan, which seems to cool just fine.

Cons: A bit pricey, but Silverstone makes the best PSU's, and I learned long ago that you don't skimp in this department.

Overall Review: This is a bit longer than even "large" power supplies, so make sure you have adequate space.

Pros: Johnny Gurus review of the same power supply found them plugged in backwards. Ok I called finally after no fax returns or email returns and was told to switch the switch opposite of on so I did and it will now run everything.

Cons: Also got a kill a watt meter from Newegg and its pulling about 1140w at the wall...

Pros: This power supply came with the void warranty sticker that was over the hole where the switch is already punched out and on single rail already.

Cons: I suspect now after further investigation it is one of the first units out that you all had a recall on where the fan control and overtemp protection plugs where plugged in the wrong place. I have been trying to get an RMA number but cant even get a return email...

Pros: 2-8 pin power plugs for the processors, modular.

Cons: I put this power supply on a X58 UD5 with an i7 920 and 2-4870x2 with water cooling on everything. Right in the middle of benching 3DMark it would cut off like someone flipped the power switch, does it immediately if I try to run Furmark also. Put everything on an EVGA classified with a W3520 and the same results. Hooked up the Corsair 850w to just see if it was the power supply and everything works fine with it.

Overall Review: I suspected the power supply be the culprit on the first build with the Gigabyte board but thought it may possibly be the board, no doubt now its a defective power supply or they just arent any good. It is passed the 30 day NewEgg return so now we will see how good RMA service is and if I get a power supply that can do what it is supposed to.

Pros: I can't say enough here. For the money, this PSU cannot be beat. Switching between independent rails or a single 95A rail is a huge plus for anyone looking into SLI. It has enough connections and cables included to support 3-way SLI right out of the box. The construction of this unit is superb, and it puts out every bit of power that Silverstone advertizes it can.

Cons: None whatsoever. This thing is named "Zeus" for a reason.

Overall Review: *Never* try to save a buck on the power supply when building or upgrading! You will not regret spending the small bit of extra money on this unit over the competition.
