need urgent help to identify 4 pin to 6 pin molex adapter

[Anamitra das]

i bought a gtx650 and sadly my psu doesn't have a 6pin connector.. i went online and find this http://www.ebay.in/itm/271906553057?aff_source=Sok-Goog but its showing 6 pin to 2 4pin... is it the same thing? ?

What PSU?

Hey MarkW, good to see you.

Anamitra, yes that will work, but we should check your PSU first. The concern is that it can handle sending that much power to the GPU. It may not be able to, and if you try to, it could cause damage or other issues.

its a generic model... it has 25a rating on12v... and i guess all psu has many 4pin connectors

OK, that 450 watt unit has 20 amps output on the +12 volt rail.
A good 450 watt unit has 37 amps output in the +12 volt rail.

My guess is, that the power supply you are using is not fit to power a video card, and that is why they did not put video card connectors on it.

Here is the label from a Seasonic 450 watt unit...

Hi,

25A means it supports about 300Watts which includes the CPU as well.

A GTX650 uses about 126W under load.

That leaves up to about 174W for the CPU. I don't think there's much else that uses 12V.

So...
To be fairly safe I'd suggest maybe only considering this for a CPU that uses 125W maximum (including draw if overclocked). Lots of CPU's use less than this so you might be fairly safe.

Some cheaper power supplies can die when you add a load even if you are within spec so be warned.

SUMMARY:
Probably will work depending on CPU. I'm always wary to recommend power adapters usually though.

i have an intel i3 2100 not overclocked..

I think you will be okay cause you aren't really using a lot of high power parts, but it would be best if you can find the label on the side, like was shown above. If we can determine the exact max wattage the PSU is rated for, we can take a better estimate if it will work. I think if you have something over 400 W, you will probably okay, since the 650 isn't exceptionally powerful. If it is less, I really wouldn't feel comfortable trying it personally.

i calculated and its closed to 400 watt.. im gonna try.. thnx guys. . u all r best
