Detonated on turn on 7/1/2016 9:38:50 AM

Pros: n/a

Cons: Power on and immediately blew, PSU popped and saw fire. Can visibly see one of the large capacitors exploded upon turning on the power switch.
Not what I was looking for after 6 hours of building the server.
RMA'd, pending replacement. Ended up RMA'ing the MoBo and CPU's as a precaution.

I purchased Two of these and they died within 8-12 months 2/3/2016 10:56:09 AM

Pros: These have many labeled cables and nice price/packing

Cons: The first one I bought died within a year, completely dead. The other one has a PCI-E output that died for some reason. Not very reliable PS

Overall Review: Going to try the RMA process and report back. (2/3/16)

Great power and stability 5/11/2015 5:03:50 PM

Pros: It is high output power supply, modular cables and optimal size.

Cons: none so far

Overall Review: Well I had a spark and small flame in my PC due to power adapter that couldn't handle current of Corsair H100i. However after clearing the burned plastic and connector, resoldering H100i wires all was good to go - no damage to power adapter or to any component.

One down, we'll see.. 2/11/2015 2:33:16 PM

Pros: It's a Thermaltake..
It's a 1200 Watt PS
When it works, it works well..

Cons: First one ordered died after 2 weeks of use, not sure why. It's rated for 1200 watts with 80+ amps on the main 12v rail. I was drawing at MOST 650 watts total, and something like(I'm guestimating to the high end) 65 amps on the main 12v rail. No reason for it to have failed, so it scared me when the lights in my house flickered; the computer popped and wouldn't cut back on.

Overall Review: Luckily, after a lengthy wait on an RMA(Not Neweggs fault to my knowledge) I installed the replacement and the computer booted up like nothing had ever happened. As a matter of fact, this review is the first thing I'm doing after the boot-up.

I'm satisfied with newegg once again, mainly because after the lengthy wait on the replacement I was surprised to see a free gift in the replacement box. Thanks newegg!

All is well so far 7/27/2014 11:20:57 AM

Pros: -Ordered Wednesday night, arrive Friday morning, doesn't effect score but you gotta love early deliveries.
-Sealed and well packaged, both by Thermaltake and Newegg
-Came with instructions, while I don't need them its nice to see Thermaltake providing a helping hand.
-Rubber absorbent corners that go between the case and the PSU when screws are used.
-Silent so far (haven't stress tested it)
-$188 with product code, that is a steal!

Cons: -The rubber absorbent corners weren't very sticky for application but its not a big deal they can keep an egg.
-No sticker makes me sad :(

Overall Review: -Gonna leave her on all day just in case, but all seems well to me.
-Upgraded from a very old Cooler Master GX 650W, It was old and loud and had to go.
-This is actually an anticipatory upgrade for the 780gtx I plan to get when they have a sale.
-I will upgrade this with any issues that occur if they occur, until then I highly recommend it, 5 eggs!

Story Time 7/24/2014 12:44:02 PM

Pros: Can support 2x Xeon E5-2600 series CPUs, and a full 16 sticks of 4 GB RAM.

Cool, quiet, and stable. No issues.

Cons: ATX power connectors were put on backwards, but that's me being very, very, VERY scrutinizing. Not a real problem.

Overall Review: There's a story to this. We recently purchased 64 Thermaltake TPX-1275M power supplies. Some of them would work properly, but a staggering percentage of them (to ballpark it, ~75%) wouldn't power on the system properly when more than 2 RAM modules were installed. It would constantly cycle power, not even POST'ing correctly.

We got in contact with Thermaltake directly (big shoutout to Dhony), and they agreed to exchange all 64 PSUs for the TPG-1200M. The entire time they were very courteous and understanding, advancing us two units to test before we decided to commit to the exchange.

Overall our experience with these supplies, and with Thermaltake in general, has been nothing less than stellar. I would rate 6 stars if possible. Unfortunately, Newegg.

Pros: Modular design, long cables, nice looking and well built, very consistent power output. Like that the fan remains on until power supply cools down after use.

Cons: None so far.

Overall Review: Useing this with 3-way sli and physics card works great holds consists power output even on long overclocking sessions. Had lost two previous power supplies while trying to overclock system.

Lots of power 5/28/2014 12:08:26 PM

Pros: Modular design. Great performance power wise. LOTS of power connections.

Cons: Pricey. I am not knocking an egg as this is expected for a good brand, great options.

Overall Review: Not sure why others are complaining of lack of power. I am running 3 way sli, 17 fans, ssd, two dvd rom, hard drive, cooler and all video cards with ZERO issues,
