Here are the graphics cards:

MSI Gaming N780 TF 3GD5/OC GeForce GTX 780 3GB 384-bit:

Here is my PSU:
PSU:
http://www.amazon.com/gp/product/B008BUST0O/ref=oh_details_o04_s00_i00?ie=UTF8&psc=1

Rest of My System:
- SSD: (Samsung 840 Pro) You know, you know.
- HDD: (Seagate 2TB)
-Case: HAF 922m Stock Fans
-Motherboard: MSI H87 - G43
-CPU: Intel Core i7 4770
-CPU Cooler: Artic Freezer 7 Pro Rev. 2
-RAM: 2 x (Corsar Vengeance 1 x 8GB memory)
-OS: Windows 8.1

I did originally purchase a GTX 770 and that ran well with my power supply. The cards mentioned above have a higher TDP though so I was wondering if someone could tell me if I would be able to use them with my power supply. Btw my PSU has 45.5A on the +12v rail.

This is only my second post here on tom's Hardware. I have visited posts on this website before but it wasn't until now that I had actually decided to join the community.

So Hello Everyone!

I meant very old like more than 5 years.

ur system only consumes like about 500W with 780 or Titan for normal gaming or rendering apps(PSU benchmark softwares will put ur psu under extreme load so don't run those)
They list higher wattages because they consider u will only run at 50% load. Because normally u get highest efficiency at 50% load(that would be around 280W for ur psu). But ur psu can deliver upto 625W without major problems. After that it will shutdown itself to prevent damages.

No I didn't make this thread to brag. I really need to know if these GPUs will run on my PSU. Please take this seriously. You may be used to being around trolls but I am not one of them.

Thanks but what do you mean by "it might age out then?" I have only had my psu for about 2 months now so it's not very old yet. So how long do you think I would be able to run a Titan or a GTX 780 on my psu before it gets to old then?

Thanks for the link but I was looking at the recommended wattage for a single 780 and it is listed as 575w. Do you know anywhere else I could reference to find out how many amps on the +12v rail the 780 or the Titan require?

Thanks So Much! I won't be running any benchmarks on the card I choose but what about running the Windows Experience Index? Does that put too much of a load on the card?
