430W enuff?

[pinky867]

Is a 430w PSU able to power a R9 270oc or a GTX 760oc?
I know that its stated, minimum requirement is 500w.
I went thru 2 power supply calculator and both gave me a result of less then 400w. My system------------------------------------>
There is also a youtube video:

Can I say that 430w is enuff to power the above GPU for short period of usage(2-4hrs)? It will be taxing if its usage go beyond that?
Will it damage the GPU if power is not enuff? or just under perform?

Please advise,Thank you.

Use the efficiency % of the psu multiply 430w and deduct off from 430w, how much left over see enough to power up the rest of the pc components.

You mean like
80 x 430 - 430?
or
80% of 430 x 430 - 430?

It is possible to run your system with a R9 270 or a GTX 760 with the 430W PSU, but there is too little wattage headroom for comfort as the systems will need approx 400W and you may need to change the PSU in the second year of your upgrade as CX series PSUs do not exactly have the best internal build quality.

If you go to the power consumption section in any review, you will find that reviewers in most cases measure power consumption for the entire system using systems significantly more power hungry than a typical system. Here is an example from Anandtech’s review of the GTX 760:

Notice how it says total system power and not video card power. It is also worth noting these total system power measurements are done at the wall so these are AC values. When you convert to the DC power that is used by your computer, it becomes lower because a power supply is not 100% efficient in converting the power. If you go to Guru3D’s review, they calculate the load of the GTX 760 to be 169w. If you visit Nvidia’s own website, they specifically mention graphics card power is 170w.

let said for GTX 760 whole system 336w from wall outlet and your PSU efficiency 85% means your pc only use 285.6w...

better efficiency u draw less power from wall outlet....

Will be able to run it with little head room left ~

Limpeh buy a 560W PSU that can overload until 850W

Wow! That is very enlightening.
Thank you, very much.

430w means it CAN supply 430w of power, so it will draw more from the socket for the drop in efficiency. Some psu can even overdrive to 20% more than rated power without problem.

So yes 430 w is more than enough for this setup. I have 2x gtx670oc Sli on a 620w psu, measure the max power only 550w required.

u have to see the build of the psu..
some 430 only 200+ w
some 430 is 300w
u have to see how

CX430M by Corsair is one of the respectable manufacturer brands...

That type of PSU is a liar-labelled junk PSU and should avoided at all costs. More respectable brands of PSU are usually designed to take more than the designed wattage on the label.

Based on CWT's budget DSAII platform with CapXon caps. Not risking it with a GTX 760...

In simple English, YES, can run, but expect your PSU to uplorry in about 2+ years.
