using two molex cables to power up my gpu?

Markuss · Oct 20, 2015

lately I have ran into a problem, I have bought a computer which didn't come with a GPU. this computer has a CiT Active 85 500W Power Supply 80 Plus Bronze PSU but it only has a a single 6 pin pcie and two molex outputs. The GPU i want to get is a XFX AMD Radeon R9 280X but im not sure how to connect it as i only have a 6 pin pcie and 2 molex outputs. i have seen those 2 molex ->8 pin but im not sure if it would work.. please help me

I don't think I would run that GPU on that PSU. It has a single 6-pin for a reason, and considering I have never even heard of the PSU brand it is probably very poor quality. 280X uses a lot of power.

Nope , that won't work , you need a reliable power supply with the correct PCIE power connections to run that card.

No adapters , bad idea.

what could i do, maybe could i get a different graphics card, any recommendations?

Get a proper Power Supply.

Markuss · Oct 20, 2015

how much are they? and i dont know how to fit in a power supply( im not a pc guru)

Dark Lord of Tech · Oct 20, 2015

Power supplies are fairly easy to change out.

Markuss · Oct 20, 2015

as i said i am not a pc guru, so what you find easy, i would probably find too risky/tricky. and is there a gpu i could run without replacing my PSU

Dark Lord of Tech · Oct 20, 2015

That PSU should be replaced anyways.

Markuss · Oct 20, 2015

i could give you my pc stats and you could tell me what psu i should have.

what watt power supply do you recommend?

Dark Lord of Tech · Oct 20, 2015

XFX or EVGA 550w

Markuss · Oct 20, 2015

550w? i was looking at 800w?

Markuss · Oct 20, 2015

would that be enough to power the gpu?

Dark Lord of Tech · Oct 20, 2015

Yes , but if you want a little room , get a 650w.

Thanks, that was very helpful

Dark Lord of Tech · Oct 20, 2015

Your welcome.

Markuss · Oct 20, 2015

okay just to get this straight, i am only 14 and i cant get £70 out of the blue. i have looked at some cheaper versions like Corsair TX650W TX 650W Power Supply, would this be okay ? or does it have to be XFX or EVGA?

Dark Lord of Tech · Oct 20, 2015

The TX650 IS ON OLDER MODEL Corsair but it is decent quality.

Markuss · Oct 20, 2015

thanks but i have decided i am going to go for XFXForce 550w as its cheap on some websites

Dark Lord of Tech · Oct 20, 2015

A great PSU made by SEASONIC , good choice.

Markuss · Oct 20, 2015

Thanks, you have been very helpful
