Can my Dell Optiplex 780 run a Radeon R7 250?

[tobin48]

I have a Dell Optiplex 780 SFF (Small Form Factor) and I wanted to install an XFX Radeon R7 250 Low Profile. I was wondering if my computer would be able to run it. From looking at power consumption calculating websites such as extreme and msi, both websites state that with my computers settings they would recommend a minimum of around 200w and recommend around 250w on both calculators. All the calculation sites I used never exceeded over 300w. Would this card be safe to use on my pc to play games like WOW on high settings?

My Settings:

Duo Core2 3.3ghz
300w SeaSonic Power Supply
4GB DDR3
1TB Memory
Windows 7

it should be safe i was actually just looking at the R7 240 for my optiplex 760 desktop. which would require the low profile card. I have 5 optiplex's 3 760s, 2 330s. i think it will work but remember these dells were designed weird. the btx case, unusual power suply unit. make sure the graphics card doesn't require direct power from the PSU. these dells (desktop form factor) don't have a 6 pin cable or other plugs made for graphics cards.
