First, the scope of supply: - Of course, the power supply wiring harnesses. - 5 black screws to the AC adapter to screw into the housing, via Phillips screwdriver but also with Allen wrench possible only 4 screws are necessary if you lose a reserve is still there. - 4 black cable ties to organize and to lead through the housing the cable. - 2 black velcro ties, suitable to hold thick cable strands. - 1.4 m long power cord (normal power supply of the power supply). - Brief but adequate operating instructions. The whole comes in a simple but good packaging. The following connections are provided on the power supply: - Of course outside the terminal for the power supply (IEC connector) with the power switch. - 6 harnesses with the following connections: 1. 20 or 24 pin ATX power (main power connection, comes on the motherboard (motherboard)). 2. 2 times 6 or 8 pin PCIe connector (supplied PCI devices that consume more power, for me, both ports are used for the graphics card uses MSI N560GTX-Ti Twin Frozr II / OC graphics card (PCI-e, 1024MB GDDR5 memory, dual DVI -I, HDMI, 1 GPU). 3. 2 times 4 pin CPU connector (CPU1 and CPU2 P4 P8), is also on the motherboard supplies the processor with power, I have only one processor, so have used only one of the connectors. 4. Harness the following concatenated connectors: SATA -> SATA -> Molex -> FDD 5. Harness with the following concatenated connectors: Molex -> Molex -> Molex 6. Harness with the following concatenated connectors: SATA -> SATA -> SATA Form Factor: ATX, so watch (probably) together with all ATX cases and ATX motherboards. Rated power: 530W. Otherwise, I can not say much about it, it does the job and powers the computer power, pledges is still that it makes to its name: It's really very quiet, I can hear normally nothing (computer is directly below the table) you have to almost be ear to the power supply to keep at all what to hear and even then it is still drowned out by my also pleasantly quiet case fan. Plug designations: SATA: is the power supply for all SATA devices (eg hard drives, optical drives) Molex: the power connector for older devices that do not work with SATA or all sorts of other power consumers (older hard drives, older optical drives, such as: my front panel Icy Box IB-863-B multi-card reader (13.3 cm (5.2 inches) eSATA, 4x USB 2.0, 2x USB 3.0) need such a connection, you can also connect the fan, but the reason is usually on the motherboard connections, you put the fan directly to the power supply, you can not control them, they run constantly at full speed ) FDD: is the power connector for a floppy disk drive, if someone has one / needs. I would highly recommend the PSU, it does its job and the pleasantly quiet and it has enough connection options.
