as the title say i want to know if the gtx 750 need extra power connector cause i hear that it doesnt need too much power from the PSU and i have 350w with 12v=16A so can my PSU runt it ?
and for the version that i want to buy (i want to know what is the version that doesnt need extra power connector) :
GIGABYTE GTX 750 TI OC 2 GDDR5
asus GTX 750
GIGABYTE GTX 750 OC 2GB GDDR5 (the non ti verison)
so please what is the version that doesnt need extra power connector and can my psu run it ? if not then what do you advice me for a GPU to my PSU (i have a quad core 8300) and thank you

Ah, two 12 rails, that makes more sense. With a maximum 12V wattage of 264W, well, in theory you should be able to run a 750 that has no additional power requirements; reviews of the 750 show a total system wattage of under 200W. But taking into account capacitor aging, the quality of the PSU, and so on, you'll be cutting it very fine, so in all honesty I'd probably recommend a PSU upgrade. You don't necessarily have to upgrade, it could work as is, but it would be very bad form of me to just say "yes, you'll be fine" and not voice my concerns.

all the ones you mentioned will consume too much power for your PSU to be able to deal with. I would higly reccomened upgrading your PSU to a 750w 80+ gold then getting a graphics card because without a better PSU your computer will be really limited to things like Sapphire R5 230 1GB DDR3 VGA which are kinda low end cards get more power then get any card you like

no 750 doesn't require extra power connector and it will run on a good 400 watt psu but it will run on a good 350 watt psu also and is one of the most power efficient cards.......some OC editions need 6 pin power connectors so avoid that........but i dont know about the make and model of your psu so i will say get a good 400 - 500 watt psu and then use that card.....

I'd agree that upgrading the PSU is a good idea, 16A on the 12V rail is cutting it too close for one of those cards and your 95W CPU, but you certainly don't need one anywhere near 750W in capacity.

Without upgrading your CPU, you probably don't really want to go above a 750 or 750 ti (or the equivalent performing AMD card), as it would be held back too much, so really, a decent 400 - 450W would be more than sufficient.

the only reason I suggested such a high PSU is due to future upgrade possibilities, with getting a beefy PSU you have the option if you get a good one to leaving that in a computer for many years to come and still be able to swap in and out the newer GPU's and CPU's without worry of running out of power :)

True, a decent higher wattage PSU can be a very good long term investment if you plan to upgrade over time, or transfer it over to a new system. Just depends how tight things are on the money side, as to whether it's a good idea, or even feasible, to spend extra on the PSU now with the future in mind. I just wanted to let the OP know he didn't need to spend more on a 750W PSU.

Sorry, didn't mean to jump down your throat on the capacity issue; just seen too many people on here lately recommending PSUs vastly over capacity who, unlike you, genuinely think a 750W or above PSU is needed for a single GPU system.

its fine I don't take anything over the internet too seriously, when I give advice for people as much for myself I try to look to the future I myself have a 1000W 80 gold+ and have done for years, I now have 2x R9 280x so a higher power supply is needed, but I may take money for people into account and give them 2 options the cheapest one then the one I recommended so people can pick and choose

first thanks for the answers,
actually my PSU 350w have is too old its a aopen AO300-08CZ that's a picture: http://www.hostingpics.net/viewer.php?id=38485200220.jpg and i have a GT 630 so gtx 750 will be very good upgrade for me and i think to buy a new computer in the future but now i just need to play games like dayz and arma 3
the psu has two rails so i think that's enough , is it ?
and my config is too old so i think it will not draw too much power:
ram : 4GB ddr2 (2 stick of ram)
hdd : 2 hdd the first one 255GO and the other one 209 GO
motherboard: asrock G31M-S
GPU: gt 630 2gb ddr3
the man in the store said that my psu can runit it but i do not trust him so what do you think guys ?

I really wouldn't trust that PSU, I would say either go for a good 450W such as cool master 80 + gold power supply if you are short on money, if you I would highly suggest that you get a 650W 80+ gold for future upgrades, the 650W will allow you to run almost every single graphics card on the market at the moment, but if you want to in the future have dual Graphic you may want to look into a 750W +, hope this helps

I would have to agree with that, but in my opinion it is so unlikely even after a year that your PSU will be able to do it, PSU are kind of like cars in a way without good routine maintenance they will lose power over time, also with low end PSU they will usually operate anywhere from 5-25% under the power supply that they have on the box so with that you need to be so careful, an upgrade in PSU in my opinion would be the best course of action
