Outsource a Graphics Card Power!!!!

[abubakarsehraai]

I have a pre-built system with a 320-watt PSU. I want to put a 175-watt TDP graphics card in it, but changing the PSU is not an option because of the OEM's 6-pin plug design. If I power that up with an external power source like another PSU or a custom 12v PSU, will it work or not?

you can make it work, but it's not easy and can end in disaster.

It is hard to imagine an OEM PC that would have a reasonable enough spec for a particularly powerful graphics card. What CPU are you equipped with in this system?

Its HP, equipped with 6th-generation Intel support. Actually, pre-built systems are very power-efficient (320 watts is enough). Maybe I can buy a custom board with a 24-pin connector rather than buy a new PSU with enough power to run that GPU.

What hp?

 

A lot of em have adapter cables that can just make it work fine.

Same as this one!

that would imply that you have, at most, a 6700K in that system. If that's the case, the system would be well-served with a graphics card like a GTX 1650, which does not require a power connector.

Yes you're right. I can go for GTX1650 or modify 24-Pin to 6-Pin. Both will work.

This modification needs a +5VDC to 12VDC converter. I can wire it up myself. Thanks for your expert opinion.

Be aware these might need 12v standby not 5v standby to boot. I think that stepup conv is for that. However these adapters are like 10$ premade just gotta know your model for that and google it.

 

Saves you work and ruining 2 good psu's

yes, I'm just suggesting that the 1650 should be significantly more cost effective. No need for an adapter, new power supply, and whichever beefy graphics card you are interested in.

 

That said, if you are dead set on the more power hungry graphics card, the 24 pin to 6 pin adapter would be fine, I have used a couple myself because they are fairly widely commercially available. Usually the product name is sorted by whatever model of prebuilt you have.
