Gtx 750 ti, psu problem

[Pizza Dude]

Hi, I just bought a gtx 750 ti, and while I am waiting for it to arrive I did some research about the power consumption, and with all the AMPS stuff I am second guessing, I have a 250 Watt PSU that comes with my old Dell PC.I needed the Graphics card for a couple of games I bought and this one looked good because of its low power consumption.
Would there be any problem? If not would underclocking help?
The label says some thing like this:
AC Input
100-120V~,50-60Hz 8.0A
200-240V~,50-60Hz 4.0A
DC Input
+5.0V --- 18.0A
+3.3V --- 11.0A (arrow to this and the one above, 120W MAX)
+12.0V --- 17.0A
-12.0V --- 0.3A
+5.0VS --- 2.0A
TOTAL 250 WATT MAX

Thanks

Sorry if I am not asking in the correct way, it's my first post.

this is a no go the evga 500b has been the value leader recently

amps * volts = watts

so 17 amps * 12v rail = 204 watts for the graphics card,

you are going to want at least 25 amps or 300 watts for that card and the overall power needed for the system is 500 watts according to nvidia

A good quality 450W is a safer bet.

The GTX 750ti PSU requirement is 300w. Not sure where you got 500. I do agree that the Evga 500b and 600b are good budget PSU's.

i think the nvidia site says total system requirements are 500 watts

The problem is I have a 545s Dell PC, with a slim psu (probably a tfx) and I live in México so I wouldn't know what or where to buy

The "official" power requirements for GPUs are always overestimated by manufactuers and for this card it is way way way overestimated.

The gtx750ti is stated as a 60w card by nvidia but crypto currency miners found that the bios on these cards locked the power limit at 38.5 watts. This means that even at max overclock 38.5w is the most that this card will draw and at stock speeds this card uses ~27w .

Convert this to amps and you get:

38.5w (max overclock) = 3.2 +12v amps

27w (stock speed) = 2.25 +12v amps

So unless your current system is maxing out your PSU you should be fine. No need to underclock and you could most likely get the typical 12% overclock on the gtx750ti.

toms hardware review on this card showed it a little over 60 watts average with spikes up to 150

I used this site and it says I need 214Watts recommended 264 http://www.extreme.outervision.com/PSUEngine
Does that mean anything?
My specs are a Core 2 duo e7400, 6 Gb ddr2, 500 Gb HDD

best of luck with that. you will have issues and when that GPU asks for more power it will ask for more amperage and since i doubt your power supply has OCP then you will probably fry your mother board and CPU while your PS smokes and goes up in flames.

every trusted reviewer puts the average power use while gaming at 75 watts or higher (bitcoin mining or hashing has nothing to do with gaming power usage)

this is guru 3d's recomendation without any overclocking
GeForce GTX 750 Ti - On your average system the card requires you to have a 450 Watt power supply unit.

here are links for proof:

http://www.guru3d.com/articles_pages/nvidia_geforce_gtx_750_and_750_ti_review,5.html

http://www.techpowerup.com/reviews/ASUS/GTX_750_Ti_OC/23.html

the guy you picked for best answer has never answered a question on this site before and also does not have any links to prove anything

you also have to subtract roughly 5% of new peak power supply for every year it is old.

so if it is 3 years old then you need to subtract 20-30 watts from your 2-3 year old power supply

Your CPU is only 65w so you should be good to go on power with room to spare.

Your biggest problem may be that your slim line case only accepts low profile video cards.

[/quotemsg
so his cpu came out in 2008 making his power supply at least 4 years old, after this time period and considering the cheap capacitors that are being used i would think a 30 watt drop from original output (if it ever actually put out that much wattage)

i would think this puts you at a best case scenario of a 230 watt power supply. do you really want to risk you whole rig for $40-50

 

[Dark Lord of Tech]

There is a good chance that the card may not run due to lack of power , and also a lot of the prebuilts are having trouble with these cards.

I searched all over the Internet and didn't find any place to buy a tfx power suply in México

 

[fkr]

maybe you mean xfx or seasonic . send me the link to where you would like to buy from and a price range to stay within.

I mean tfx form factor, not brand. It's a slim case.

maybe a best buy

here is a list of etailers in mexico and around the world

use at your own risk i do not know any of these places

Ok thanks for all your help, I'll check it out later now I am going to sleep
