Can I use this with a 750 watt PSU for Crossfire and a 500 watt PSU for everything else?

I think it should be fine. On their website they have multiple (2, 3, 4) PSU daisy chained up. This device just turns them on at the same time.
1067925
Yes. Remember that all of your motherboard components must be connected to the same PSU, so in your case, I would use the 500W PSU as the primary to power your motherboard and CPU, and use the PCI-E headers on the 750W PSU to power the cards.

I have my whole system hooked up to a 750 watt PSU except for my second card, which is hooked up to my 500 watt PSU. So if you're putting both cards on the 750 watt PSU then you should be fine.

Yes. The wattage of either PSU doesn't matter. This dongle just allows you to trick the second PSU (the one connected via the MoBo cable) to turn on when the first PSU is on.

Hmm... I think a 500W PSU would be ok, but are you overclocking the CPU? If so, then I would recommend checking the necessary wattage for the GPU. I'm using a 750W PSU, but I think other people have used less. I would research this further since I'm not 100% sure 500W would suffice. I'm sorry if I couldn't be more helpful.

Depending on what else you have, and if you over clocking your CPU or the GPU it won't work. 750W is your best bet. I'm stuck in the same boat as you cause I'm trying to buy two but it won't work but I'm not trying to buy another PS

This is an AMD card. I think that it can be crossfired, I see a connection near the top left of the product picture. Although I have read somewhere that you will need at least a 650W power supply.

Most likely not, you simply wouldn't have enough current available. I wouldn't use anything less than a 750 W

I tried crossfire with 2 7870's gigabyte cards with a 850 watt thermaltake power supply and it wouldn't work. I recommend no less than good name brand 1000 watt power supply. However a 1200 watt would optimal.

I don't know what your entire system power requirements, but unless you have a ton of extra equipment running you should be fine with 750 watts. I'm running that gpu with a 650 Watt power supply and have zero problems.

Yes 1250 watts is more than sufficient to power both cards. They both turned on for me with a 1000 watt PSU.keep in mind that these cards require two eight pin PCI-X connectors. Not the standard six pin. To crossfire two cards you will need four separate eight pin connectors.

Hi. It will work but I would upgrade the PSU to one at least: 500w. I got the XFX TS 550w Full Wired 80+ Bronze Power Supply - P1550SXXB9 . The anufacturer says to use at least 300W of PSU, but you know that they come overrated, I mean, it is rated over their capabilities. You should read this review: http://www.tomshardware.com/answers/id-2111729/msi-gtx-750-twin-frozer-work-500-watts-power-supply.html hope it helps. ;)

The single slot GPU does NOT use extra power (harness) from the PSU. It works strictly from the mobo power. Your 500 watt PSU is going to work just fine....

I would say no. According to AMD's website the recommended is a 500 watt PSU

750 Watt should be plenty!!! You may have a bad power supply and it may need to be replaced that happened to be before. I have an tx 850 corsair power supply and I run 2 of the r9 290x crossfire, 2 ssd, 3 hard drives, i5 2500k oc 4.7 ghz, sound card and a ton of other stuff. Hope this helps

That should be fine. It depends on what MoBo and CPU you're using, fans, and if you plan on doing any overclocking. I personally went with a 750w PSU to make sure I wouldn't have any hiccups.

you should be fine as long as you arent planning on running a super high end graphics card with it because 500w might be a little bit low for some of the major graphics cards. but if you're just gonna run something like a 6850 or something you should be just fine. hope this helps

Yes 750w will be fine, if you want to go sli in the future though you're going to need to more wattage.

When I purchased this graphics card, I had a 500 Watt power supply and had problems getting it to turn on. I replaced it with a 600w power supply and it fixed the problem. You should be good with the 850w power supply but I'm not sure how it will work in crossfire mode. It's a great product and I highly recommend it for prospective gamers

It will work. What Corsair tried to address here is the Haswell compatibility problem, which the CS series line was completely cleared of. This line works perfectly fine for any mobo. You will need a pretty strong GPU to justify 750W though; be sure not to fall for marketing tricks. 750 W is usually too much, by quite a wide margin, in most PC's I come accross with.
