pp1111 Posted June 13, 2009 Share Posted June 13, 2009 I have a HX620W power supple wants to use with my Supermicro C7X58 MB http://www.supermicro.com/products/motherboard/Core2Duo/X58/C7X58.cfm But it require a 8pin 12V ATX AND 4pin ATX 12V This power supply come with one ATX 12V 8pin modular cable. Can I request for a ATX 12V 4pin modular cable? Any charge? Or if I use a 4 Pin to 12 Volt ATX Motherboard Power Adapter, is it safe/stable? Thanks very much for your help.

Wired Posted June 13, 2009 Share Posted June 13, 2009 As per the motherboard manual: 24-pin ATX main power connector +12V 8-pin CPU power connector +12V 4-pin Secondary power connector (this is recommended, but not required for normal operation) It is strongly recommended that you use a high quality power supply that meets ATX12V standard power supply Specification 1.1 or above. It is also required that the 12V 8-pin power connection (JPW2) be used for adequate power supply. However, the 12V 4-pin power connection (JPW3) is optional, but may be necessary when increased power to the installed peripheral cards is needed. In otherwords, unless you have a power hungry peripheral card that's sucking power, and for some reason doesn't have its own power cable connections (like most gamer video cards do), you won't need the +12V 4-pin secondary power connector.
