No & Yes
Yes you will need to connect a 6 pin PCI-e connector (in fact you need two for the GTX 460) to power the card.
The "Auxiliary PCI Express graphics power connector (1 x 4 pin)" is their to power the card by slot for stability and for cards that don't need any 6 pin connectors so it may work without or might be unstable without it.
I also have a DX58SO motherboard. I haven’t completed my system yet, still buying piece by piece. I will be using at least one, then maybe two EVGA GeForce GTX 470 graphics cards.
I am very curious to know which power supply and case you are using.
My board, version E29331-703, does not have the 4 pin auxiliary pci express graphics power connector but is does have a SATA-style auxiliary power connector. Reading page 54 of the “Desktop Board DX58SO Product Guide”, I’m led to believe this connector serves the same purpose as the 4 pin one.
My case is the Antec 1200 and I want to buy an Antec CP-1000 power supply next. I don’t know if this power supply will have the right connectors for two GTX 470 cards (it has 2 [6+2] pci-e, and 2 pci-e connectors shown on their spec sheet). Do you have any comments or if anyone else knows more about this, please chime in.
I'am using "IN WIN " casing and power supply also same brand with 750W.This power supply has 4-PCI-E power connectores,which means can use 2 EVGA GeForce GTX 470 graphics cards.
Also "IN WIN" power supply has SATA-style auxiliary power connectors as follows:
750W has 6 connectors and 850W has 8 connectores.
if you need more clarifications pls reffer " IN WIN "official web site.
But if you are going to use Blue-Ray drive together with above graphics cards it better to use 850W power supply.According to my understanding IN WIN power supplys are little cheap and very easy to use.
Thanks, you helped me confirm I was on the right track as for power supplies. I’m not going to be able to use the Antec CP-1000 with two EVGA GTX 470’s. Reason being, the number of different connectors. It looks like I’ll go with Antec TPQ-1200 or research a different brand. Antec has been good to me so far. I had already decided on 850W or better. A higher wattage should keep me within EVGA’s other requirement for this card, “minimum recommended power supply with +12 Volt current rating of 38 Amps.” In some ways going big when building a computer ensures easy upgrading later. I'll take a look at IN WIN too.
Hand built computers are only as good as the research you put into the components, then the price. I was up to $1800.00 last check but that will change more or less. Just can't afford everything in one purchase. I'll checkout SeaSonic for the power supply. I have the Antec 1200 case and Intel DX58SO board so far. Some of the other items on my waiting to buy list:
A minimum 1000 watt power supply, with connectors aplenty for the rest of my list and upgrades.
Intel Core i7 950 processor.
Crucial memory 12GB kit (4GBx3).
EVGA GTX 470 graphics card (one now and add another later).
3 WD HDD (750GB and two 500GB).
I already have a decent ViewSonic 19" display. Other things like optical drives, keyboard, mouse and stuff are to be determined at a later date.
