Help with case fan PSU adapters

Like all PSU's, yours will come with FEMALE 4-pin Molex output connectors - these are the ones with four HOLES in a line. In the photos at the top of the page you linked, click on the third from left that shows all the modular output cables. The bottom left two are the Molex outputs ones. One has three 4-pin Molex females, the other has two of these and one smaller female 4-pin output connector to power a floppy drive you won't have. The power-consuming device, be it a hard drive, an optical drive or a fan, has a MALE connector with four PINS inside a protective shroud. If you ar buying case fans with common 3-pin fan connectors on their wires, you need an adapter that has a MALE 4-pin Molex on one ends, and a MALE 3-pin fan connector...

The power-consuming device, be it a hard drive, an optical drive or a fan, has a MALE connector with four PINS inside a protective shroud. If you ar buying case fans with common 3-pin fan connectors on their wires, you need an adapter that has a MALE 4-pin Molex on one ends, and a MALE 3-pin fan connector on the other end. All such adapters come with this configuration. Unlike fans designed to plug directly into PSU outputs, common case fans have FEMALE connectors on their wires to mate with the pins of mobo male fan ports.

If you are powering all your fans from the PSU via Molex outputs, you should emember that such outputs can supply lots of power form MANY fans from one 4-pin connector. (This is unlike mobo fan ports that are limited to a max of 2 fans per port.) So you should plan to get adapters that convert one PSU 4-pin Molex output into many 3-pin fan (male) outputs.

My own preference is to power all fans from mobo fan ports and allow the mobo's systems to control fan speeds automatically, according to case temperature sensors. If you connect a fan to the PSU directly there is no way to achieve automatic control and the fan(s) just run at full speed.
