GTX 660 power supply requirements?

[nandakaskus]

Recently I bought a GTX 660 (non ti). I know the minimum spec for the psu are 24A + 450W. I wonder if it can be usable using a 450W PSU.
My PC specs is (currently) :

Dazumba DZ 450W (5V 36A, +12V 16A, +3.3V 18A)
Core 2 duo E8300
1 sata 320gb hdd + 1 ide 80gb hdd
4gb dual channel ddr3
geforce gt210 1gb

EDIT :
my PSU doesn't have any 6-pin cable

450W is a minimum requirement for 660. Your PSU can handle it. I would recommend 500W PSU though.

It is not the wattage that matters in this case; you need 24A on 12V rail, and your PSU provides only 16A. It is also a bad quality PSU, and I can only recommend you to replace it.

In fact, this graphica card *can* run on 450W PSU, but only a quality one which provides enough amperage on 12V rail. For example, XFX Core 450W, which provides 34A on 12V rail. Compare that to the 16A your PSU provides and you can immediately see the difference in quality.

Since the PSU is the most important component in your system, and directly responsible for the longevity and safety of your components (not to mention you can reuse a quality PSU in your next rig, even the one after it), do not, by any means, cheap out on the PSU. Get a quality one.

My recommendation: XFX Core 550W.

 

[EasyLover]

Agreed in terms of Amps with above.

 

[nandakaskus]

what will happen if my psu doesn't enough to power it up?

 

[nimits]

I would recommend
Corsair CX750M 80
with reasonable price and performance.

Depending upon the cause, you may not get display or system will shut itself down.

 

[herrwizo]

Worst case scenario (and most likely), it will blow up, potentially taking your other components with it. *Do not* attempt to power it on by any means. It is apparent that it lacks amperage *by a large margin*.

Will this PSU work?

http://www.corsair.com/en/vs-seriestm-vs450-450-watt-power-supply

probably it's 80 certified

 

[EasyLover]

Better get XFX series 450W pro if you are not going for 500W.

 

[CGurrell]

As above, XFX 450w unit is the best one to go for. Also, worst case scenario continued: PSU will go berserk and destroy anything connected to it (CPU, motherboard, drives etc).

 

[nandakaskus]

There are no XFX distributors currently here. Corsair VS Series 550W is the better choice then?

 

[CGurrell]

Which country are you located in?

What other make/models are available in 450-550W range in your area plz?

 

[herrwizo]

Take a look at this list:

Pick anything from Tier 1, Tier 2A or Tier 2B that is available in your country.

sorry for late reply.
I'm thinking about buying one of this :

FSP Hyper 500 500W 80+
Corsair VS Series 550W
Cooler Master ELITE V2 500

 

[Alan Caldwell]

None of them are as good as the Seasonic especially Corsair and Cooler Master. Get the model I suggested.

None of these actually. But if only these options are available then go for vs 550. Don't overclock system on this PSU

 

[CGurrell]

nandakaskus, the best unit for you BY FAR (It's not even close) is the one Alan Caldwell suggested, the Seasonic S12ii 620w unit. If you're not going to buy this then we can't recommend anything else. http://www.flipkart.com/seasonic-s12ii-620-watts-psu/p/itmd5xz46hjzzrax?pid=PSUD5XZ4GCGRASAY&srno=b_1&ref=1bdf5a30-8be5-4636-bdbe-589d76b07be4

Only if OP is from India!

And why the hell my gtx 660 run on a psu 350 w with 36A combined on 12 rail ? (and has 300w combined on 12v) i got this combination for about 3 and half years, and still working today. And i play games with 99% load for hours on GPU.Ha ? you got a answer for this? PSU model : FSP350-60APN . Haha.. not to mention that i use a old CRT DELL 21 inchi that consume 120 w ! Oo STOONED !

Can I use a GTX 660 graphic card with this PSU?: B-move 600W OEM.
My old NVIDIa Geforce 9600GT died and I need to replace it. 🙁
