ASUS GTX 750Ti installation HELP needed

PreeceUK · Oct 2, 2014

Okay, I've recently bought a brand new ssd & a new asus GTX 750ti. The issue I have is that the new graphics card requires a 6 pin connector to be plugged into it, my PSU doesn't have a separate slot to add one of these cables. Now I realise you can buy 2x 4 pin molex to 6 pin adapters, but I have no free connections left in my PC as my ssd used the last one.

I'm incredibly new to replacing components and I need some help with what I can do here, the problem with buying a brand new PSU is that I don't know how to wire everything back up once I replaced the old one.

Thanks, Alex

If I am correct and you have no more power cords available free (which is not understandable as you must have 6 pin or 6+2 pin power cables free) I would get a Molex Y cable -

You don't need dedicated 6 pin power connector for 750Ti. Just install it on PCIe slot. This slot will provide 75W which is sufficient for 750Ti.

That is also true, however, that Asus model does require the 6 pin power connector as it is over the motherboard power limit under max load. Similar threads have had the same scenario for the Asus.

Point taken. Thanks.

That's if he is referring to this card -

go buy yourself a cheap true rated psu with 6 pin power connector, it cost about 20 dollars if you can find 1.

unknownofprob :

Yes, true. For this model 6 pin power connector is required as this card takes near around 150W.

RobCrezz · Oct 2, 2014

EasyLover :

There is no way in hell that 750 ti would take anywhere near 150w. Its going to be taking 60-70w max.

Sig2525 · Oct 2, 2014

you sure thats a gtx 750 ti? all the 750 ti i know does not need 6 pins

that is like a gtx 760/770 twin frozer whatever or something.

RobCrezz :

Go ahead and read for yourself what Asus has mentioned:

RobCrezz · Oct 2, 2014

EasyLover :

You are misunderstanding. It has the connections available to draw up to 150w (75w 6pin and 75w from pci-e slot) - There is no way a 750 ti will pull that much. The bios for the 750 ti has a power target of around 38w!

Sig2525 · Oct 2, 2014

i bet the 6 pin connector is to power those 2 fans haha just kidding.

return your 750 ti and get another w/o a 6 pin

like this one

if same performance the 750 ti w/o a 6 pin will be more energy efficient.

Sig2525 :

Asus does not make Twin Frozr Cards, That is MSI. As far as that card goes it is the Asus GTX 750Ti DCUII

http://www.newegg.com/Product/Product.aspx?Item=N82E16814121855

That Asus is one of the best GTX 750Ti's your going to get, keep it.

unknownofprob · Oct 2, 2014

Robcrezz, A far as what needs to be connected - EasyLover you are correct.

"The card requires a single 6-pin PCI-Express power connector. This power configuration can provide up to 150W of power. You can not use the card without the power connector (I tried)."

http://www.techpowerup.com/reviews/ASUS/GTX_750_Ti_OC/5.html

The power consumption is 74W max 'NOT OVERCLOCKED'. This means that the power consumption will exceed 75W overclocked and also above the slots maximum output (75W)

RobCrezz · Oct 2, 2014

unknownofprob :

Not disputing the need of the 6 pin on this card. But 750 ti's can work just fine and overclock without it. despite popular belief the card can draw more than 75w from the pci-e slot.

If you check your own link, the 74w max is under load test, it only peaks at 65w in games.

Look up some other 750 Tis and see for your self. As I said, there is no way you need 150w of PSU power for this card.

unknownofprob · Oct 2, 2014

That is not the entire point, it will not run without the 6 pin power connector. Overclocking the card exceeds it's power of 74W quite easily, if not the case Asus would not bother with the 6 pin power connector at all. I am not saying it reaches 150W, it doesn't but what other power connector can be used for that little extra power it needs? - No other.

"Look up some other 750 Tis and see for your self. As I said, there is no way you need 150w of PSU power for this card."

When did i say it reaches 150W? - never.

"If you check your own link, the 74w max is under load test, it only peaks at 65w in games." - I said this, It was "NOT OVERCLOCKED" to reach 74W. Above the point it still has the ability to draw more power then the slot can deliver.

You didnt say that, the post I originally replied to said that. You just jumped in making incorrect statements.

"You didnt say that, the post I originally replied to said that."

Actually you said that when quoting me. "Look up some other 750 Tis and see for your self. As I said, there is no way you need 150w of PSU power for this card." <- That was said when quoting me.

"You just jumped in making incorrect statements."

I don't even see how this is relevant at all. if you look up higher in the thread I was the one stating requirements and offering solutions before you were going on about power usage. The only thing I can see as incorrect is your judgement to power usage for that card.

EasyLover · Oct 2, 2014

Wowwww! Looks like I missed the debate. Just got back from office. Gave that reply in office during the spare time. I believe we all have put this thread on a wrong track. Please stop debating about power and help out the OP. Shall We!

Sig2525 · Oct 2, 2014

if that 750 i needs a 6 pin then go grab a psu with 6 pin or just get a 6 pin connector. 450 watts should be fine for a gtx 750 ti.

i run my 650 ti boost with 450 watts and 1 6 pin connector.

ti boost > 750 ti
