Is my power supply enough for a gpu upgrade?

I was wondering if my PSU is enough for a GPU upgrade i have a fx-9370 with a Gigabyte 990fxa-ud3 rev.4 and my current GPU is a his iceqx2 R9 280x and was looking in to upgrading to a sapphire vapor x R9 290x with the 8gb buffer and my PSU is the coolermaster V750 is that enough to upgrade to the sapphire?? 

I'd say you'll be fine unless you're running tons of HDs or watercooling. Yea your hitting the 650w+ load of the 750 watts on the PSU. Considering your CPU is near 300 watts and the GPU also at 300 watts. I would just watch it, if your PSU is restarting or turning off in a few months, I would get a new one.

Coolermaster V750 is way enough for any single gpu.

a setup like that, wont be even close to 750W ussage.

 

yeah i mean i looked it up and it said it could almost use 500 watts out of the psu and ik my processor takes alot that's why i was wondering cause i just redid my computer and at the time i wasn't planning on upgrading the gpu and now im thinking about it lol.

The test system they have used in the graph is a 4960X with 290X vapor X OC´d, total system power is 480W measured from the wall, so this is including the efficiency rate of the psu.

4960X can be compaired to a FX9370 in terms of power consumption.

You will be totaly fine with that 750W psu.

Allot of people look at Thermal design power numbers (TDP) of a cpu or GPU, but these numbers have nothing to do with power consumption.

I just finished reading Intel's white paper on AMD's ACP vs TDP, and have made a habit of reading Intel CPU datasheets.  TDP numbers from both companies have everything to do with power consumption, an they are useful as a guide to size both power supplies and CPU coolers.

There must be a language barrier or something you don't understand, MisteryAngel, because the primary sources on things like TDP, namely Intel and AMD, are very clear about what these numbers are, what they mean, and how they're used.

You aren't exactly right, TDP does not directly mean how much power the components are gonna draw, I have done tests of this my self, You can see MisteryAngel's graphs, and just for good measurements, here's a video from Linus, saying the same thing. TDP stands for THERMAL design power, and if you didn't know, thermal is basicly a synonym for heat or temperature, TDP refers to how much heat and heat waste the component is gonna have. Not how many watts it's gonna take up.

Thermal design power  TDP only means the amount of heat, that your cooling solution should be capable to dissipace from the cpu or GPU. thats it, nothing more, nothing less.

Or in short terms. Heat output.

it doesnt tell anything about power consumption! The thing is that 8 out of 10 reviewers have no clue what they are talking about wenn it comes to power consumption, But they just read whats on the box lol. ☺

MisteryAngel are you consideiring 100% cpu load consumption? or 100% gpu load consumption? I remember reading somewhere an OC'ed 8350 can take as much as 370 watts. Your total power consumption chart doesn't differienate if they are Intel or AMD systems. Sure Intel system will never hit 200 watts OC'ed but AMD system it's different.

Here's a video. 600 watts with just OC'ed 8350 & 7970. www.youtube.com/watch?v=cap1fr1bwws

750W will be more then enough for a 290X and FX9370. even 650W will be totaly fine.

Here's just another video that shows it. www.youtube.com/watch?v=LiWThqgFfI4

Guys.  For a CPU, Watts dissipated is Watts consumed.  Don't get hung up on the word "thermal".  Go read the Intel and AMD primary sources.

It's not cool to stay ignorant just for reasons of ego.

Over the years AMD and Intel have provided TDP numbers but have used the term to mean different things.  At this point Intel's TDP numbers are a little more useful but they both mean something very specific and are useful for sizing power supplies.

For example, if you go read an online magazine and design your cooling based on their consumption numbers, and their numbers are lower than Intel's TDP number for that CPU, then you have designed what would be considered an inadequate cooling system for that CPU.  And the power supply needs to supply every DC Watt that is dissipated, so it needs to be sized with Intel's TDP number in mind as well.

If the TDP number is lower than the most brutal synthetic program can consume, then it's a judgement call whether you want to design for the higher number.  Intel's chips throttle and many designs rely on that.  A power virus can come along any time.

As DIY builders, as a practical matter, we rarely run exactly the apps on exactly the hardware that we're building, before we build it.  TDP numbers are a good starting point and an excellent data point for designing the cooling capacity and power supply capacity.  With that said, getting an idea of system consumption from a magazine, and multiplying by 1.5 is likely to work.  Using the TDP number will likely lead to a slightly smaller PSU being chosen but DIY builders usually oversize anyway for a variety of good reasons.

In the future, if anyone would like more info on how exactly to use these TDP numbers I'm happy to explain it.  I don't think TDP is some perfect number, I'm saying it's useful to size PSUs.  For DIY I believe it's near indispensable.

 

Enough to put 2 290s

im not ignorent, because i do read your message very closely. Since i respect everyone. i definitely not ignoring your post.

TDP is thermal design power, stands for heat output, as also explained in the Linus video.

It does not say anything about how much power a cpu consumes, its just a measurement to determine how much thermal power that needs to be dissipated from the die.

^t+1to that. Also, reservation station, don't call people ignorent when you don't know them? that's just a douchbag move.

Thank you everyone for your feedback.
