ASUS ROG THOR 1200W Power Supply review - Product Showcase

So again, the PSU is modular for all connectors, since you'll be using those anyway, we're good with that. These are all black.

As you can see, there are a massive number of power feeds/connections. Basically, you can hook up six cables for your storage units and PCI-Express graphics card cables connector, you get eight of them (!). The PCIe graphics connectors are each tied to their single own +12V rails with 100A available. 

At the front side, we spot a small honeycomb air vent; it allows for airflow running through the PSU, cooling down its components and keeping them nicely efficient. Also, obviously we spot the power connector and the on/off switch. The product remains fairly small with a length of just 16 cm - its complete dimensions are 190 x 150 x 86mm. 

At the top you'll stumble into a silent fan. The PSU fan is an IP5X-certified 135mm wing-blade fan, a double ball-bearing fan. The Thor is advertised at a maximum operating temperature of just 50°C. However, you can go passive for the bigger part, let's peek at the next photo:

Classic Seasonic is a Hybrid mode, enable it and even at 100% load the power supply fan will remain inactive (passive) for roughly 10 minutes, so with a more normal PC you could run passive all the time. It is a fact that when power supplies are really efficient, they lose less energy, and lost energy is heat. At up-to at least 80% load this power supply remains under 50 Degrees C.
