Is this psu enough for a gtx 470?

It's a coolermaster 650 watt with dual +12v rails rated at 18A each

 

You have 36 amps total while the GTX 470 requires 38. It may work, but I would not trust it.

 

Yeah,I was afraid of that.No room in the budget for a gpu and psu.

 

You can't just add up the rails anyway.

 

I'm not bothering to put you to sleep with the stupid equation used to determine the the exact output of multi-rail PSU (another reason I got the PSU I did), but it does give out more then the 18A on the single rail (another example would be using more then one GPU and having the amperage requirements decrease with every additive). It's not 20A under versus 2A, but it is still under.
Something like this anyway;
(Power=Voltage by Current) -> (Current=Power divided by voltage)
So, 1: I hate math. 2: I just barely passed that test on PSUs (well that part anyway in my defense ) 3: I avoided it altogether

 

u should be good if your psu is 80plus

 

That makes sense.I guess.

 

On my friend's rig, a 650W Corsair PSU can run a Phenom X6 BE (OC 3.8), 8GB RAM and a 480 GTX (never OC'd) so I think you get a yes opinion from me... Depends also on how many peripherals you have on it also.

 

The 650w corsair has much more amps. And I'm glad that math stuff makes sense to you, because it mostly goes over my head. You can definitely look it up to get a more exact equation. There may be even a sort of online automated deal to figure it for you. No idea.

Like I said, It may work, but I would not trust it.

 

It will be fine, nvidia allways over etstimate what a card needs so you stay on the safe side.

 

a 550W OCZ does the job for my brothe with a X4 965BE, a 4850 + 8800GT (physx card)

 

Using the Thermaltake Power Supply Calculator it says I need 700w. Doesn't say anything about amps. Says I need 600 with my 4870. http://www.thermaltake.outervision.com/

 

I have no problem with my PSU and my GTX 470s. It provides 70a across two rails, with 1 card attached to each rail.

 

What does that have to do with anything,

It will still deliver 650W independet of its efficiency, be it good or bad.
He is safe to run 470 with his PSU, unless he got 20+ HDD hooked up to it.

 

I'm with 650W from Chieftec to the configuration from the profile and i don't have any problems except that when i game the PSU gets so hot that i cant hold my hand for more then 5 seconds on top of the case(where is the PSU) is that normal?
P.S. My case is with very low airflow 2x80mm 1 at front and 1 at the back.

 

Get the enermax galaxy, put thoses sob's in sli and you will have no problems whatsoever.

or wait until the gtx 485 comes out then put thoses suckers in sli.

 

Ok I guess I can add from my experience.

I recently bought my system but it keeps freezing and artifacting when stressed, and now the Gigabyte support guy says my 650W PSU isn't powerful enough for my system, even though it's supposed to have 52 amps.

I don't have any other stuff connecterd except for a dvd burner which i never use. So now I have to try a bigger PSU, which won't be cheap

I guess what I'm saying is that it's better to buy a powerful PSU in the first place.

 

It'll work fine with a single GTX470. People seem to forget that the GTX470 has the same level of powerconsumption as a GTX280.

 

Never underestimate the importance of PSU. It's what hardware needs to feed with.

Well if you decide to invest your money into an 'error-potential' solution, I should advice you to choose a well-branded / trusted PSU like Corsair, as to invest into a more 'error-proof' solution.

 

You could just use a pci current connector and the other one from two different molex rails using an adapter. Then maybe you get in specs with the AMP's too. But I still don't think you will run into problems with that PSU
