can GTX 650 RUN ON 400w psu

[Karan Luniyal]

i am thinking of buying a zotac gtx 650 for gamiing purposes and nvidia has announced that it will support directx12 by future driver updates. so my psu is of 400w.my psu doesnt have 6pin so i will use dual molex to 6pin.can i run in??

MY SPECS (in case u need them)
cd/dvd player (lg)
intel pentium duo core e5400 2.7
currently 210 nvidia(using pcie slot only , no 6pin)
2gb ram
any information u need u can ask me. for ex amps and 12+ volts etc etc
THANK U VERY MUCH

Never open a power supply yourself. If you're not careful, it may even result in death.

This... Not worth the risks brah.

Can i run run ati r7 240 DDR5 1gb with boost

Or any gpu without upgrading psu..

This is not a point of debate. 12A on the +12V rail will not run ANY card, not even a Geforce 210, which is one of the lowest TDP cards in the world. Get a new PSU.

 

[cst1992]

I opened mine and soldered a new fan into it, aslong as you dont touch any capacitors you'll be fine but the components in there could shock you but wouldnt kill you its only a small glorified dc transformer rectifier circuit, the only voltage that could kill you is the voltage entering it, after the transformer its all running on 12v how can that kill you?

Really? You must be having an inverter at home, to use when the power goes off. Its battery is quite big, but is still 12V of DC. Try touching that with your bare hands. If you survive, post back here.

 

[matt20020]

Yes really, and I dont have an inverter in the house.

But thats not the point to die from a shock you need voltage aswell as current plus when your working on something like that common sense tells you to unplug it from the mains before hand. The only component that will hold a charge is the power factor correction capacitor and even thats on the secondary side of the circuit, and the charge from that may shock you but would not kill you, chances are once you switch it off this will be dicharged within the circuit anyway

 

[matt20020]

The only thing that holds a voltage of 240V is the primary windings of the transformer whilst it is turned on, to get a shock that will kills you, you need voltage aswell as current.

You could get current burns from a low volatage and high current but you would not die from it, but this is unlikly unless you have it turned on whilst working on it!, and to get dicharge current off the capacitor you would have to touch the legs on it, and this would probably only be a mild shock as power supplies use mF capacitors

 

[matt20020]

so who looks stupid now lol

 

[matt20020]

you just mentioned that the voltage rail is 12V, do you even know what this is?, I don't think you do myself!

 

[cst1992]

You don't need 240V to get electrocuted, and we're not talking about the AC current here either. Even if the power supply is not plugged in, there is still charge left in the capacitors, and they take a lot of time to discharge(ideally infinity, but practically 5-6 time periods; 1 TP = the time required to go from 0 to 0.707*full voltage).
Actually speaking, voltages don't matter, current does. A current of even 1A is enough to kill a person, did you know that? I'm pretty sure the PFC capacitor will have enough charge in it for a long time to produce a current of that order.

And about the stupid part, you're looking stupid, as you're quad posting.

 

[matt20020]

will the current be able to flow through your body if the voltage is not enough to drive it?

 

[matt20020]

here you go bit of basic reading for you lol

[cst1992]

This is getting too much now. Power supplies are not meant to be user serviceable, and I'm not going to recommend anyone to do it, end of story.

 

[matt20020]

ok i agree with you on that one, and appoligies for going on. And I didnt recommend any1 to do it, things like that should only be done if you fully understand whats inside and how it works, sorry just got a bit carried away at getting my point across but for the general person no it shouldn't be messed with, its for easier to just buy a replacement.

Ok guys, thank u
And my budget is now 8000 rs
So ican i get a nice psu with nice gpu in this range
I live in india so please tell me.
And i m getting ati r7 240 1 gb gddr5 1gb with boost at 5770 rs
Any suggestions?

 

[Karan Luniyal]

Plus i forgot i m getting crosair vs 450 at 2200 rs

[cst1992]

usually the sweet-spot for price/performance is seen, but since you only have a dual core e5400 processor, those cards won't use their full power on your system.
You'd be well off getting a GT640:

Get only the GDDR5 version. There are many cheaper DDR3 2GB versions, but they perform worse than this card, and you don't need the extra RAM.
Total 6900+2200 = 9100.

what about msi r7 260x 2gd5 oc
and crosair vs 450(uk)

 

[Karan Luniyal]

i m getting msi r7 260x 2gd5 oc at 9866
and crosair vs 450 at 2141
please see does this psu will be enough for my system

ihave asus p5kmpl amps motherboard pci2.0
will there be a bottleneck?

 

[cst1992]

Unless you plan to upgrade soon, the 260x is WAY too powerful for your CPU.
Get the 250 or GTX650 instead.
