Hey guys, as the title says,
Will the Sapphire Nitro R9 380 (4GB; GDDR5) be okay with a measley Cougar CM700?

I did some research, the 380's minimum power requirement is a good 500w PSU with 30a.

With that said, the CM700 has 700 watts with two 12v rails running at 30a each.

I know many will say "That's a bad PSU, get another one" -- sadly, im on a budget. And as long as this PSU won't harm any other components in my PC, i'm fine with it.

Video card's PSU "requirements" are pure BS.

Like in this case. R9 380 power consimption is 150 watts max. 30A@12V means 360W. That's 210W difference.

So that PSU should run card just fine.

I think that's a different one, mate. Here's the picture of the said PSU: 1274859844.jpeg

I'm worried about the quality, tho. You think nothing bad will happen? :)

Probably not. Quality is medium grade but not "bomb" category.

  Very true there is a theory that has been rampant in techsupport type forums where they think you need a "750w PSU" or better at all times regardless of the GPU specifications -- claiming "overhead" and a lot of other BS, 95% of the time they aren't builders or testers they are just internet techs parroting the same BS over and over. Ever wonder why we see Dell 480w PSU's running GTX 970-GTX 1060-1070-GTX 770-R9 270x-280-380-390 just fine? It's because that Dell PSU is fairly high quality and has a strong +12v rail. If you know your PSU's you can easily get by with a quality 550W-620W-650W with a high end GPU just fine.
