My PC draws 900 watts alone. Not to mention my 3 monitors, laptop, backup server, etc. Is this even viable?

No chance. Your PC probably does not draw 900 watts by itself, even if you have that big of a power supply, but, this thing was garbage. Outlets shut down if you draw too much power and it appears you are going to exceed. Buy an APC instead. I bought the Pro 1500 and it is excellent.

It depends upon how many graphics cards you mount and how many hard drives. 850 Watt should be plenty of power.

I'm not sure what the power usage is, but it runs flawlessly with my 350 watt power supply.

It depends on what else you are running in your system. I bought this with a 750 Watt power just to be safe, but if you are not running that high power usage of hardware, you should be fine.

My power supply is similar and I have been using it for about a year now with no issues. I also use dual monitors. I'd at least try it out.

Depending on how many HDD's, optical drives and cpu, a decent quality 350 watt should work fine. We've ran it in two different computers with a 500 watt antec and 550 watt antec with zero issues as far as power, a quad core and two HDD's in one pc. In fact, my system with a GTS250 only pulls 200-210 watts (total, system wide) while gaming and despite being an older video card, it does pulls a lot, so 350 should do the trick if that's all you have at the moment.

Hi. I wouldn't try it with less than 500W. Obviously it doesn't consume that much, but if you're thinking of upgrading to this card, you probably have a couple hard drives, a higher-performance CPU and so on, and would need that much for other reasons. I had a 400W PS that was unable to power my system a few years ago, resulting in BSODs and random freezes, so I changed that out for my current 600W supply, which does just fine. I have an 8-core CPU, this video card, an SSD and four hard drives. I just had a look at EVGA's specsheet about this, and it says minimum 350W PS. I would imagine that is in a minimal system with nothing else hooked up. If you have any plans to upgrade anything in the future, being stuck with a tiny power supply will limit your options. I'd say start your search at 500W and if you find a good manufacturer of a more powerful one that's reasonably priced, get it.

I am running it on a duel monitor set up, with 3 hard drives and 3 case fans on a 600 watt power supply, so I would assume, since I only have 100 watts more than you, that it would be fine. However, I'd advise you to double check with power consumption tools, I recommend cooler master's power consumption tool ( http://www.coolermaster.outervision.com/) to save you the hassle, that is the link for it. But I assume it should be fine.

You shouldn't, but it depends on what else is on your machine. I have 3 hard drives and added this card, which only uses 110 watts, and it's working fine with a 500w PS. That's one reason I selected this card because of it's low power consumption.

The TDP for a GTX 780 is 250W. Unless you're running a LOT of hard drives or some cpu with a huge power draw, you should be able to use this power supply with power to spare. I think it's unlikely that the rest of your pc is using 250W. I am running a crypto mining system with 4 video cards (each with a TDP of 150W) with this supply and it's only pulling 700W from the wall. Let's assume about 15% efficiency lost to heat so.....that implies that the system itself is actually only drawing about 600W from the PSU.

The power supply that I'm using is 400W on a Gateway system. Seems to perform pretty well and I've had no problems so far.

It should be well more than enough to cover it. That combination, even overclocked, should use around 500W of power, taking into account everything you'll have in your system.

Major energy user in modern comps is a video card...Without video card, 300W more then enough.If you will use powerful modern video card you have to change PSU if not 300W would be OK

Really depends on what else your running. But if your not very USB heavy and your not using much else only standard stuff like a single hard drive. Should be ok on 460. I use a litigation stuff though so I'm on 750watt
254691
Yes more than enough. I run LSI 15,s and monitor 70,s as side surrounds plenty of power.

Almost definitely. I was running it on a 500w PSU but I also have a lower power consumption from my CPU to help with that. Unless you are running it with a AMD 9590 or something like that, 650w PSU should work great.

Hi robert,Sorry for the delay, I used a watt meter to see how much my system was using. I have a big CPU cooler and this graphic card and I was reading 300 or so watts at the wall receptacle. I lean the way of others. While you could probably get by for a while with your power supply, solid voltage = stability in the computer world. If your PS is always near its limit, you may run in a lot of issues. A PS is fairly cheap and easy to install. I have a seatronic 750 S series to give me room for expansion in the future but it may be an overkill. A good 650 would be just fine for sure.Regards Hi robert,Sorry for the delay, I used a watt meter to see how much my system was using.
