I bought this power supply to replace one that died on my HP Desktop PC. The dimensions were the same and it was a perfect fit. The main power plug fits both older 20 pin ATX type connectors, as well as the newer 24 pin type on the motherboard (20 pin + 4 pin). It comes with a 4 pin ATX 12v power cable, 4 SATA device power cables, 3 of the older AT device power cables, a floppy drive power cable, PCI Express 6 pin power cable. The cables are fairly long, and are enclosed by sleeves. This unit is quiet, with a very large fan located at the bottom of the unit to provide efficient cooling. At 400 watts, it provides ample power for my needs. The instore price was about $13.00 higher than the online price of $49.99, but I just asked for the online price, and they complied. All in all, this is a great deal for the money!
What's great about it: Flexibility, quiet operation
