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

Normally, I do not recommend using adapters, but a 6-pin cable is not needed for many of the GTX650s out there, so if Zotac needs one, it must be just barely, so it should be safe. What brand and model is that "400W" PSU?
If you have the money, you could get a GTX750Ti, GTX750, or HD7750, all of which are stronger that the GTX650 and do not need auxiliary power. Make SURE you get a GDDR5 version, not one of the abominations sold with the much slower DDR3.

it says there 400w but I would suggest you use a bronze type single rail power supply if you can.
I would go for at least one of these two if you can
http://www.amazon.co.uk/Corsair-Builder-Series-Bronze-S...
http://www.amazon.co.uk/XFX-ATX-550-Power-Supply/dp/B00...
this way it'll allow power for any additional upgrades in the future aswell better to go higher on the power than not have enough in the future!

An 80+ rating means that the PSU was able to provide its claimed wattage, but at the unrealistically low temperature of 23C. In the absence of a competent technical review, it gives some small hope that the unit is not junk, but is no sure thing.
The number of rails will not matter. In a multi-rail PSU, the rails have OCP trip points set to protect vs. overloads. Note that some companies may claim OCP protection when in fact competent technical reviews have shown that the required components are not present (e.g. some CoolerMaster "Extreme" units). The rails are not strictly additive, and power is never "trapped" on an under-utilized rail (contrary to an old Corsair marketing myth).

yes whats the 12volt rail amps.It is written below +12v = 12a
And -12v = 0.5 a
And max 22a
Is this what do u need ?
Can you post a picture of your power supply sticker? Which company is your power supply made of? Seems to be an aftermarket PSU. The Chinese PSU's they supply have more amps than these, even though they also are never sufficient.
12A is too low. Please post a picture for more clarity(upload on sites such as imgur and post link of image here).

Best solution
You'll not be able to run any graphics card(and I mean any) on that power supply; it has only 12A on the +12V rail. Your CPU, hard drives, usb devices, fans, all that stuff will easily eat up all those watts. You install a graphics card, it'll not simply boot; or damage the psu; or damage the graphics card.
Get a new PSU first. And you're right. You're left with no choice.

to know if a power supply has a single rail the only way is to open it up most power supplies that come with a standard PC are either two or 3 smaller supplies used in conjunction with each other, hence a power supply thats 500W with two rails will have 250W per rail which means you can overload it easier by having a load excedding 250W on either one of the two rails

if you go for that XFX power supply above you should be fine, aslong as your not crossfiring to graphics cards, if you need a bit more power then maybe go for something like this.
http://www.amazon.co.uk/Seasonic-S12II-620-ATX12V-Stand...
basically your graphics will be around 75W max, then make an allowances of 150W for the standard components, then 25W for each additional fan

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?

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.

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

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

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.

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.

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:
http://www.flipkart.com/zotac-nvidia-gt-640-1-gb-ddr5-g...
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.
