For our European friends Thermaltake Toughpower 1500 W seems to be a great power supply, targeted for the extreme enthusiast that wants a power supply running around 50% of its maximum capacity for saving on the electricity bill due to the higher efficiency presented by the power supply when it is working at half of its maximum capacity – plus the ability to deliver way more power than any other product on the market if the system requires.

One of the highlights of this product it the support for eight power cables for video cards, allowing you to install up to four very high-end video cards that use two auxiliary power connectors each. Almost all high-end power supplies provide only four auxiliary power cables for video cards, allowing you to connect only two very high-end video cards without the use of adapters.

Internally this power supply has two separated 750 W units. Usually when a power supply has two transformers several components are shared (active PFC circuit, switching circuit, monitoring circuit, etc), but this isn’t the case with Toughpower 1500 W. The only thing shared by the two power supplies is the transient filtering stage and the rectifying bridges.

Another great feature is the use of only Japanese capacitors and even solid aluminum capacitors on the +5 V and +3.3 V filtering stages. This was the first time we saw a power supply using solid capacitors. Capacitors tend to lose their electrical characteristics over time, especially when exposed to high temperatures, and the use of better capacitors provide a far higher life-span for the product.

Just to remember Thermaltake guarantees that this unit can deliver 1,500 W at 50º C, with 1,600 W peak. Unfortunately as we have already explained on the beginning of this article, we couldn’t put this unit on our load tester.
