The 1200W ZM1200M from Silverstone provides the power you need for your most intense applications. It can continuously deliver the full 1200W at over 80% efficiency. Six +12V rails easily balance the heaviest power load. Switch from 6x17A rails to 1x95A rail depending on your needs. The auto-switching input can handle all common voltages so all you have to do is plug it in.

The power connectors are fully modular. This lets you use only the connections you need. There's a handy carry bag for the extra cables, so they’ll still be around when you upgrade. The cables are all sheathed to make the inside of the case look neater, plus it helps with airflow.

The efficient internal layout only needs an 80mm fan for cooling. This keeps the noise to a minimum, and it means more power can go to running your system. The system of your dreams needs power, the ZM1200M delivers.

  • newegg ATX12V and EPS12V Compatible Compatible with the ATX12V (ATX 2.3) and EPS12V standards, the Silverstone ZM1200M provides maximum power stability to drive the latest Intel and AMD processors as well as other components for desktop and server computer systems.

5 out of 5 eggsRemoving the sticker doesn't void the warranty!!!

Pros: I've had this power supply since April of 2009, and I have not had a problem with it in the least. And, the one that I got was used off of another site. So, all in all, my PSU has seen well over a years use, and has been a part of over four builds in the last year. This is the only "true" modular power supply on the market today that is able to push 1200W of power @95 amps on a SINGLE +12v rail. For enthusiasts that can actually use this amount of power, this is the ONLY power supply to own.

Cons: The reviewers that didn't research the "problem" with the rail selector. (See below)

Other Thoughts: Don't pay any attention to those that gave this power supply only one egg! As you can see from the manufacturer's responses, removing the sticker over top of the rail selector switch does NOT void you warranty.

This product deserves a 5 egg ranking, so I had to post my review of the product to help raise its ranking.

5 out of 5 eggsDa Bomb

Pros: The other reviews on this psu are about the first ones released, Silverstone has since fixed the sticker problem on the rail switch with this psu. I love this thing, it runs a classy 762, 3 275's OC'd, 10 case fans, 12 gigs of ram, and a corsair h50 with out even a skip AND I have the extra power molex for the PCI's as well pluged in. This psu will not disappoint you

Cons: to many people whiney people

Other Thoughts: Do the right thing and buy it.

5 out of 5 eggsExcellent

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.

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

1 out of 5 eggsGood Product BUT...

Pros: Good PS, Good Design, 100% Modular, Switchable between 6 Rails and 1 Rail

Cons: Switching the rails is a pain, have to open up the power supply PLUS voids your warranty

Other Thoughts: If it wasn't for the HUGE CON I'd give this product 5 EGGS! Silverstone needs to make this feature more accessible without voiding the warranty or omit it

Manufacturer Response:

Thank you very much for purchasing a SilverStone and we apoloigze for the confusion. Your ZM1200M is still under warranty even if you remove the sticker that covers the rail switch.

1 out of 5 eggs

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...

1 out of 5 eggsTo The Manufacture Rep

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...

Manufacturer Response:

I apologize for the confusion, Unfortunately the sticker was again applied to some of the later production runs by the factory. The recall for the thermisters only applied to non-modular Zeus 1200W (ZU1200M), your ZM1200M is not affected. If you are not getting an e-mail return from us, there is a possibility that your e-mail server is blocking our e-mails. We recommend that you contact our US office directly by phone if you still did not receive our e-mail. Our phone number is:

909-465-9596

When calling, please ask for tech support or RMA support, thank you.

1 out of 5 eggsWhat a Joke

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.

Other Thoughts: 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.

Manufacturer Response:

Thank you very much for purchasing a SilverStone. From your description, the ZM1200M may be activating its over current protection and shutting itself down. The default setting from the factory for the ZM1200M is for six +12V rails for server-type applications. For high powered consumer PCs, we recommend switching to single +12V rail mode. You can refer to this document for information on how to change from default six +12V rails to single +12V rail:

5 out of 5 eggsAmazing! You want this PSU...

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.

Other Thoughts: *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.

5 out of 5 eggs100% Rock Solid

Pros: The modular cable ports clearly state which rail they will be using. This is IMMENSELY helpful for power-hungry video cards that require 2 PCI-E power connections and for balancing out the rails. Can be switched into a single 95 amp rail!

Cons: The switch to enable a single rail is under a "warranty void if removed" sticker. VERY misleading.

Other Thoughts: Sounds like a server power supply when first turned on. This is driving a q9550, 3x 8800 GTX, and 3 SATA HDDs. I used a multimeter to test molex output under full load and they are exactly 12 & 5 volts.

Manufacturer Response:

Thank you very much for purchasing SilverStone. For ZM1200M, we will still cover your power supply under warranty even if you remove the sticker over the rail switch.

3 out of 5 eggsNot really happy

Pros: Modular cables, can be switched to single-rail with95M 12V capacity.

Got my rebate check in a very timely manner. I explained to the rebate dept that there was a delay because I had to RMA it and they only declined me once, by email, another email to them fixed the problem. The rebate dept is good.

Cons: Poor switch to go to single from 6-rail, 6-rail voltage barely adequate for high-end video card, poor customer service. Cost to RMA to them was not covered, out another $17. So-called 8-pin connectors were 6+2-pin, which is not unusual but I think a bit misleading. The customer rep said he'd get that changed, I see it hasn't been.

Other Thoughts: Did I mention poor customer service? They lied to me as well, telling me when I asked for a replacement instead of a repair that there had only been 1 run of these, ever. I found out from another article that there had been more runs. The switch was covered by a piece of material which is why I sent it back (They also acted surprised, when at least 2 articles from reviewers mentioned this problem months ago. I'm not talking the sticker, I'm talking material inside the case.). They said they checked it out, but I got this weird chirping noise every once and awhile and no way this thing is stressed for it's specs - I don't know what it is, and now I just have to wonder what that noise means and is this thing going to hold up.

I bought Silverstone because I thought it was a good company, it was in the past, I have one of their PSU's and a case and am quite happy with both. That is no longer the case, they are just run-of-the-mill at best. Buy someone else's high-end PSU.
