So here's my build:
Motherboard: MSI-Z87 G45 Gaming
Processor: Intel I5 4650K Haswell
CPU Cooler: Cooler Master 212X
Ram: 2x4GB Cosair Vengence Pro
VGA Card: Asus Matrix Platinum R9 280x 3Gb
HDD: WD Blue 1TB
SSD: Plextor M5 Pro 128GB
PSU: Cosair CX750M 80+ Bronze
Case: Cooler Master N400 Case

Does it have enough power to run it? Thanks in advance :D

Hi there, monitors don't run off the computer's power supply, they run off their own built in power supplies, so there's nothing to worry about.

but the video card does and it has to process the graphics to the monitors, I am trying to hook up 3 monitors myself but to no avail. I have installed the HFX 7850 and antic 550 w ps, my card supposedly can run 4 monitors but I cant seem to get 3 running, do I need to upgrade my Power Supply? thank you

Once again, monitors run off their own internal power supplies, that sounds like something else is wrong, pjtoves. It has absolutely nothing to do with your power supply wattage, there's a reason why monitors have a power supply, after all, and not plugged into your computer's power supply.

How are you connected up to 3 monitors? I believe that one of the DVI ports uses the HDMI wiring as well, so to have triple monitors you'd essentially need to have one connected to DVI, one connected to HDMI and the other connected to DisplayPort. If you are using adapters/converters, you will need an active adapter, not a passive one, and these generally tend to be a bit more expensive to buy.

That's correct. I assume it was also indirectly a question about Graphics cards though as he thought extra monitors may increase the power consumption of them.
