Thermaltake Toughpower 1500W has, without any doubt, an impressive capacity. Actually it is a real power house since it can deliver 1.5KW at 43°C ambient and on top of that efficiency throughout 20%-100% load is high while the fan, even at full load, produces little noise. To speak frankly I didn't expect the fan to be so quiet since ultra high capacity combined with Silver efficiency means significant energy dissipation, something that demands very good airflow to remove the heat. Regardless, the fan proved to be up to the task without being annoying.
Moving to the negative aspects of the unit, what troubled me most was efficiency at 5VSB which was terrible and also the fact that the unit is not ErP Lot 6 compliant, since at standby, power consumption is about three times higher than ErP's limit. However with a small design change or the appropriate standby PWM controller, phantom power could easily drop below 1W and I wonder why Thermaltake didn't demand this from Enhance, since the unit already plays in the high cost category where design faults/omissions like this are not forgiven. In addition the cable exit hole needs some attention too since it's quite small and it doesn't have a grommet, so the cables are pressed against the edges and if you move them around a lot then most likely you will severely damage them and at worst case cause a short. Finally, I think that the biggest problem of this unit lies in its ultra high price which cripples its price/performance ratio. Thermaltake should revise the pricing as soon as possible, if they wish to boost sales. With so many powerful units, although none with 1500W capacity, being sold for under $300, competition is really tough for the TP-1500M.

To sum up, if you think that your power needs are huge and only a 1500W unit can cover them then you have only two choices, with one of them being TP-1500M. If you can afford its very high price and don't care about efficiency at low loads then you will be left satisfied since it can really handle 1500W of load so even four high-end VGAs along with other power hungry components won't pose a problem for it. If Thermaltake decides to lower its price close to $300, installs a grommet on the cable exit hole along with an On/Off switch then I could easily recommended TP-1500M to everyone that has crazy energy demands, since it's a real power house.
