Hi, just some clarification needed. As there are no details on the corsair website about the HX psu's searched a bit and found this:
" There are a total of nine cable sets for the HX520W:
Permanently connected:
* 19" cable for main 20+4-pin ATX connector
* 19" cable for 4x12V EPS12V
* 19" cable for 2x12V AUX12V
Detachable:
* 2 x 21" cable for 6-pin PCIe connector
* 2 x 31" cable with three 4-pin IDE drive connectors
* 1 x 16" cable with two 4-pin IDE drive connectors
* 6" 4-pin IDE to two 12V only 4-pin IDE connectors (meant for fans)
* 6" 4-pin IDE to two floppy drive power connectors
* 2 x 25" cables with two SATA drive connectors
The HX620W comes with two more 25" cables with two SATA drive connectors for a total of 11 detachable cables. "

Both have 2 x 6 pin PCIe connectors (however in another fairly recent review corsair now has 2 x 6+2 pcie connectors. Forgot the link).
The only limiting factor (apart from power) for the 520W HX is the 4 sata drive connectors (8 on th 620hx). But since these psu's are modular, can one get extra sata cables to connect more than 4 sata drive on the 520 hx?
