I bought this to upgrade my old 300W PSU in my Dell(which has been modded a lot!) which was getting to its capacity and affecting the performance of my computer. So this is why i purchased this, don't let the price worry you, its not low quality at all. The PSU itself comes with 1x24 pin (20+4) Connector which is able to fit the 20 and 24 pin motherboards, 1x6 Pin PCI-Express, 1x4pin +12v, 1xFloppy,4x4pin molex(2 seperate cables), 2xSata(1 cable, 2 connectors).
There are plenty of molex power cables for fans but i found i needed another sata power cable. Instead i got a sata power cable and hooked it higher up on the existing sata power cable. You could also get a molex power to sata power adapter if you find you are short of a cable.
The PSU has a very good cooling fan which covers a majority of the bottom of the PSU case and airflows out the back, which i've found overall has worked well in my computers airflow set up.
When you buy this you will need to get the appropriate power cable if you don't already have one, and also PSU screws if you don't already have these. Overall this product so far has been perfect and a great buy. Cheap, works great and best of all is gold! What more do you want from a power supply?
