Will it work if I have a 750w PSU as the main with a 850w PSU as the secondary?

Yes, this device is dumb (in terms of engineering functionality) and only meant to start up the secondary PSU when the primary is initialized. It will not turn off the secondary PSU when the first is disabled, but this will not cause damage to any connected components either.

Yes. It is worth noting- this device is "dumb" and merely tells the second PSU to activate at the same time the first is powered on, so order doesn't really matter. Imagine if the two power supplies were both hooked to the same "on" switch. For example, if you run crossfire graphics cards that consume 600 watts at peak performance, it is not safe to run them on only one unit of a 500w+500w. You should either spread each card across a different power supply or seek a better solution. There are "smart" devices that can spread a power load over multiple power supplies, but they are much more complex and expensive. Yes.

Yes, but make sure both PSU's are plugged in to some sort of Battery Back Up + Surge Protection. Otherwise you'll fry both during an electrical surge.

NO!!!! That will not work. Please do not do that as you may damage the power supply. You would need to add additional circuitry.

I had to bump up my power supply to a 750, it was a 450w, but you should have no issues. fyi, it consumes 4 power connectors, so you may need adapters if you dont have 4 available.

Yes, if it is a bronze standard 500 watt power supply. I recommend 700 watt bronze standard power supply if you want to over clock your cpu, memory, and graphics card in the near future. This graphics card has tweaking capability.

Yes, if it's an atx mobo that is an atx psu., but you should be more specific about your power needs. Is 750 enough or too much? Find a psu calculator online. It will help you.

If it physically fits in and you have enough space for cables, then yes. With powerfull and reliable PSU you can forget about this part for years.I myself used a 700W PSU for 6 years with no trouble. At the same time I was constantly upgrading everything else.

It should work but knowing the rest of the system would help also try pcpartpicker.com and build your system there and it will give est. wattage

Yes. I am running it just fine off a 650W PS. Make sure its a decent quality Power supply though.

the power adapter fits the 750, so I would think that it should work on the 780 as well.

I have a 850w power supply. A 650 will probably work. But like most things bigger is better and if you're gonna spend the money on a good card I would at least think about a bigger power supply. It's a great card though well worth the price.

I'm running two of these on an 850W PSU, so really anything above 350W should be fine, but you might be pushing it at 350W

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. ;)

Yes this should work for you. Be aware of how many and what type of connectors you may need for your hardware. Otherwise this PSU has worked with no issue since I purchased it.

It will power your system without an issue. With those specs I would suspect even a 500 watt PSU would work but if you plan on upgrading in the future or putting that video card in Crossfire you would want the 700 watt. Here is a link to a a PSU calculator that should help you in the future, http://www.coolermaster.outervision.com

It depends on how many other things you have in your system, but 850w should be more than enough. I'm running my card on a 550 W PSU right now. As long as you have the needed power connections off your psu you are golden.

Considering how this psu failed in 6 months when i have been doing heavy duty gaming.. I think the answer is no. But if you were asking if this unit can supply enough wattage for your build, the answer is yes. UNLESS you are running SLI/Crossfire, in which case go for an 750 or 800W.

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