Can I use a single Molex from the PSU that has 2 6+2 outputs and plug the 6 and 6+2 into the card? Or should I use two separate cable from the PSU?

6+2's have a downside of being unstable when you start to get into higher power draws, it's always better to have individual 6 pin connectors from your PSU to make sure you are able to get sufficient amp draw that your card will need.

6+2's work. The little loop is unsightly, but that's the whole downside. I had to do that for both of mine.

It should usually you can separate 2 of the male ends on the supplied power cords. Best bet is to just give a quick email to EVGA support

Hi, you just need a 4-pin molex plug from your PSU. If you're unsure of this plug, simply Google it and check some images to see what it looks like. It's the most common power adapter on PSUs, though SATA power connectors are becoming the norm. Still, just about every PSU has molex plugs.

Most powersupplys have a 4 pin molex I'm not sure what 3 pin connection you have on your power supply. I left the fan on low (as a case fan) because I used it in a low power system

You will need multiple power supplies on two home power circuits. Most home circuits cannot handle one massive PS (1800+ watts) for 6 cards. Figure 300 watts per card x the number of cards (when mining). Most suggest a 750+ PS with at least a 60 amp 12 volt rail to support two cards running non-stop. If you want to support more than two cards per PS, then choose a 1K or above PS for the 290(x) but I wouldn't recommend &gt;3 cards for a 1200 watt PS. To use multiple PS with one mining rig use a PS splicer (sold on Amazon) or use g00gle and search for "using multiple PS in one computer". There are free methods to start up PS without an adapter.

my system has a 350W power supply..does that mean i am ok getting this card? or do i need a separate 300w supply? sorry i am new to this... any insight would be appreciated... thanks

The ons cable that has 3 Molex spots can run up to 3 of these at once, but I would strongly recommend pluging them ingo your mother board so that you would have some control over the fan speed via the bios.

Mine has a 6 pin pcie molex connector. It's bundled up, unused with the cable management clips.

If I'm not mistaken this power supply has two 4 pin connectors, so you should be fine. The 6 pin is for a graphics card. If you would like I can pull mine and take an inventory of the cables it has.

No it uses a standard 4 pin MOLEX adapter off a ATX Power supply unit, it comes with the adapter to convert the power to the smaller 4 pin motherboard power connector that most fans use, if you have a extra motherboard fan power connector, you can just connect it to that. Although the MOLEX power is more constant and won't put a drain on the power regulator on your motherboard.

the wattage should be fine but you also need supplemental power plugged directly into this card from the psu.

it comes with 2 power connectors 2 6pin which can be pluged in the power supply. i only use one of them and the other 6 pin on my psu on mine works grate so u need 2 6 pin it comes with them though just make sure your psu can hold them.. GL

Only one 6-pin. If you can afford a top gfx that requires an 8-pin connector, get a better psu... I've used 9800GT and 660 GTX with this without any issue. ps: I bought this psu for $40 and the current price is not reasonable. Look for a better model and better deal.

I'm using 850W one for cross fire. I think 450W would be fine for single card, but it depends on your other hardwares.

You need to use and plug two PCI-E 8 pin power cables. Using Just one would harm your Card. It comes just with one 8 pin adapter because it is usual that power supplies have one of it. If your power supply has two 8 pin power cord use them directly. Use the adapter just in case ur pwr supply has one on it. But.. if your power supply does not have Any, it is time to buy one new. Remember.. it is NECESSARY to plug both, otherwise you will harm your nice and expensive Card.

400W is the min required for the card as long as you are only going to run 1 and you have at least 1 6 pin pci supplementary power connector coming off the power supply. if there is no 6 pin pci supplementary power connector then the PSU is not compatible.

I can tell you this, and it might not directly answer your question:the powersupply is not designed to be very powerful, it was made to save on power costs. It is also non-standard, so you need to take that into account.ALSO,It has 2 displayports, out of the box. although I haven't tried hooking up 2 at the same time... so you may just need one additional card
