be quiet! Pure Power 9 CM 700 Watt PSU Review - Product Showcase

 

So again, the PSU is fully modular aside from the motherboard ATX power connectors, since you'll be using those anyway, we're good with that. These are all black and sleeved.

As you can see, there are a decent number of power feeds / connections. Basically you can hook up three cables for your storage units and two PCI-Express graphics card cables (each split into two connectors), but we'll show you that on the next page. The PCIe graphics connectors are each tied to their own +12V rails with 30A and 36A available on each. 

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 160mm x 86mm x 192mm. 

At the top you'll stumble into a silent enough fan. The PSU fan is 120mm and seems to be based on (but isn't the same as) a Silent Wings revision 3. That latest iteration of Silent Wings intake fans have blades specifically designed to move more air through the power supply components with less noise than conventional fans used in power supplies, which you can see on the blade design of this 120mm unit. Believe it or not, there's actually a lot of science going on with fans these days.
