Toughpower 750 W is today the most high-end power supply from Thermaltake and they are going to release very soon 850 W, 1,000 W and 1,200 W models on this very same series. This model, internally called W0116RU, features a modular cabling system, a big 140 mm fan, is EPS12V-compatible and should deliver more power than any regular user needs, being targeted to SLI and CrossFire systems. Let’s take an in-depth look at this power supply.

Being a high-end power supply, Toughpower 750 W features high-efficiency and active PFC. According to Thermaltake this power supply has an efficiency up to 85% (compare to 50% to 60% on regular power supplies), meaning less power loss – an 85% efficiency means that 85% of the power pulled from the power grid will be converted in power on the power supply outputs and only 15% will be wasted. This translates into less consumption from the power grid (as less power needs to be pulled in order to generate the same amount of power on its outputs), meaning lower electricity bills.

Active PFC (Power Factor Correction), on the other hand, provides a better usage of the power grid and allows this power supply to be comply with the European law, making Thermaltake able to sell it in that continent (you can read more about PFC on our Power Supply Tutorial). In Figure 1, you can see that this power supply doesn’t have an 110V/220V switch, feature available on power supplies with active PFC.

This power supply uses a very good cooling solution. Instead of having a fan on its back, its fan is located at the bottom of the unit, as you can see in Figure 1 (the power supply is upside down). A mesh replaced the back fan, as you can see. Since the fan used is bigger than fans usually used on power supply units – even bigger than big fans used by power supplies using the same system: 140 mm –, this unit is not only quieter than traditional power supplies, but also provides a better airflow.

In Figure 3, you can see this power supply modular cabling system, used by its peripheral cables. In Figure 4, you can see the peripheral cables that come with this unit.

This power supply comes with two peripheral power cables containing four peripheral power connectors and one floppy disk drive power connector each, two Serial ATA power cables containing three SATA power connectors each, two PCI Express auxiliary power cables for your SLI or CrossFire video cards and one ATX12V/EPS12V cable. All these cables are connected to the modular cabling system and use a plastic sleeving, which helps with the PC internal airflow.
