Will my 750 Ti need a 6-pin Power Connection

[deltainsanity]

I'll be getting my hands on a used Asus GTX 750 Ti (this card http://www.newegg.com/Product/Product.aspx?Item=N82E16814121855&cm_re=asus_gtx_750_ti-_-14-121-855-_-Product) and I want to put it in a desktop at my dad's place so he'll be able to do a bit of gaming with it. The thing is I don't think his power supply has an extra 6-pin connector, will I need to upgrade the power supply or is there a way to get it to run without it? I know some other 750 Ti's don't have a 6-pin connector at all, so is there a way to run this card without one?

Thanks!

yes it has a plug for a 6-pin.

and no if the power supply does not have such a cable then it means it most likely does not have the juice to run it.



full specs of the computer you want to upgrade?

USUALLY it's a good idea to not run a card that has a PEG plug off a PSU that doesn't have a PEG cord. This is one of those cards that may be an exception, but a LOT depends on the PSU in the computer and what it has in it.

The 750ti is a Maxwell based chip, and it's an extremely efficient chip for what it does. Usually a 6pin will carry 75w, and here's the kicker, the PCIe slot is capable of supplying 75w according to spec. Does that mean this card magically needs 150w? No, it's still only a 75w card.

I would say, if you have a decent 350w PSU, a nominal CPU (ie: no 6 core overclocked thuban!), then get a 6pin -> molex adapter to provide the nominal amount of power needed. A 75w CPU, 75w GPU, and 100w in MOBO/RAM/HDD and you're only at 250 of 350w.

If you have a 300w or smaller, or the PSU is of 'nominal' quality, then skip the adapter. Find a different solution.

That means it is an overclocked card that needs more than 75w to function, and as such does indeed magically need the additional power the pcie cable provides.

First up, the 750ti as a reference is a 60w rated TDP card. That does NOT require a PEG connector for additional power. Now, in the interests of making sure someone doesn't overclock the card more and burn out a motherboard overclocking it, putting a PEG on it would ensure that it doesn't wreck someones day by allowing UP TO a potential 150w - not that someone would really achieve stability at that type of OC. Somehow, I think our OP is not looking to do that anyhow, so it's a moot point. The PEG is for safety reasons, since it might be close to that 75w limit that the PCIe slot can supply.

Secondly, evidence of power usage:

Please go to the middle/bottom where they cover:

1) build (4770k, SSD, Asus 750ti Strix 2GB) - not the exact card, but close enough and which is actually clocked a little higher than the straight 750ti-oc that's being considered.
2) power consumption which never broke 200w at the wall. Even after they overclocked it. 185w to be exact.

So - he should be fine as I mentioned as long as he has a decent 350w PSU, that would give him more than enough headroom for a normal build, even if he has to go with a molex->6pin adapter for the PEG connector.
