I would be on my Third one if I RMA it because of the 12v rails ,They look good and have great spec's except for just being rated at 40c.When I first get them they work great and the 12v rail is at 11.92v which is good and I have tried this on serval motherboads ,After 5 months of useing it the 12v rail would start dropping ,it went to 11.84,to 11.74v and to around 11.5v and I would get reboots ,game freezes and BSOD,Now my secound one is doing the same thing after three months when I got my RMA back the voltage was good and I started getting random reboots and BSOD's and I checked it with a volt metter and when running it under a load the 12v rails was at around 11.3v,and after looking at some customers reviews ,I notice that I am not the only one with this problem, so I need to RMA it again,But I emailed Thermaltake about this problem and I fineally got a email back after the third one and they said ,

"This issue is being looked into. Since we have to deal with headquarters in Taiwan, it will be a bit before some real answers come up.Please return it back to US for RMA. Newegg may have received a bad batch that was sent out.
That must be a big batch of bad power supplies since the first one I got was on 5-30-06 and the second one I recieved back from the RMA was on 11-16-06.

That really sucks and since it shares the same design as the OCZ GameXStream 700w that I have, I will keep an eye on the 12v rail. Thanks for the info good luck with your RMA!

I just bought the 750 today. I'll let you know how it goes.

I'm done with Thermaltake after going through three pumps on my old big water kit in less than 2 months. :thumbdwn:

I used to be a big fan of their products too. Their customer support is horrible.

If it was me I would send back that Thermaltake ToughPower 750watt and get the SilverStone Zeus ST75ZF 750watt,which also has 60amps on the 12v rail I have had great luck with SilverStone ,I am running the Zeus 560watt SilverStone right now on my 8800GTS SLI setup with Core 2 Duo E6600 Overclocked to 3.6gigs at 1.35v on a Evga 680i SLI with four sticks of PC8500C5D and four harddrivers 2-Seagate 250Gig in Raid-0 and 2-160Gig in Raid-0 and X-Fi Gamer soundcard and two Samsung SH-S183L DVD Burners and four 120mm case fans and it has'nt shut down or I have'nt had no errors on my 8800GTS saying there not enough power even tho I have them overclocked to 640/1800,and it has a single 12v rail rated at 38amps and 45amps peak,But i order a Olympia 650 watt which has 54amps on the the single 12v rail,plus it has the new PCIe 8pin connector for future upgrades on the new video cards,I know I am pushing that Zeus 560watts to it limmits I could'nt believe it handle all that.Hopely you will have better luck with the 750watt Thermaltake toughPower then I have had with the 700watt.

This is not good news. Besides whats in my sig, my toughpower is also powering 4 dvd writers and 2 hd drives as well as fans and lights... I'll have to keep an eye on it.

I take it yours is modular the same as mine? Is it all lines that are losing power or did you test it through the motherboard power connector?

No the Thermaltake ToughPower 700watt that I bought is not modular,I have never liked modular Power supplies,I always heard that they lose some power because of the modular hookups ,But the main reason I did'nt want a modular is because they did'nt fit good in my P-180 case ,they got in the way of my bottom fan.
