Are both 24pin atx power connector and 4pin atx 12V required to be connected?

[LordSnailz]

According to the manual, it looks like I need both the 24pin power connected and the 4 pin atx-12 power connected as well?

I'm not sure if I'm misreading my manual or not, but it seems like I need both connected? Can someone clarify what the difference is?

It's an ASUS P5DL2 with a P180, as some of you guys know, it's a real task trying to get the 4pin atx-12 to reach all the way to the top with a Antec 400W SP2.

Depending on your CPU It *MAY* run okay with out it but on full load I you may have some stability issues to say the least.

The 24-pin main PSU connector does not replace the 4-pin ATX-12V connector, but rather is an upgrade that channels even MORE power into the mobo. Just like the move to 1GHz+ processors and video cards with hardware T&L made necessary the upgrade to the 4-pin 12V connector, the move to dual core processors and SLI graphics cards has made it so you need not only the 4-pin connector, but also an extra 4 pins in the main PSU connector.

I'd go shopping for an extension cable for you 4-pin 24V cable, because you absolutely NEED that connector plugged in if you are running a high performance system and want to keep it stable.

Yep, anywhere there's a plug on the motherboard for a power cable, you should probably have something plugged in. Possible exceptions are using a 20-pin ATX cable on a 24 pin connector or a 4 pin 12V cable on an 8 pin connector.
