Will the new GTX 750 Ti work on my system?

Blade Mastr · Mar 4, 2014

Okay so here's the deal, the new GTX 750 Ti came out a few days ago and the price right now is 149.99 for the EVGA one. I saw the performance and it does a hell of a lot better than my GTX 660 1.5 GDDR5 OEM GPU. What my actual question is do I have to change my PSU? On Nvidia's website it said the minimum reccomended PSU is 300w and my PSU is at 430w. The reason I am asking this question is because I do not know if it will still work or need a replacement PSU.

Link to the product I want to buy:
http://www.evga.com/products/Product.aspx?pn=02G-P4-375...

Here are my PC specs:

CPU: i7-3770
R.A.M: 16Gb 1600 MHz
GPU: GTX 660 GDDR5 1.5 Gb
PSU: 430w
HDD: 2TB
ODD: Dvd Burner RW
O.S: Windows 8.1 64-Bit

Will I have enough headroom when I switch my GPU out for the new GTX 750 Ti?
Man if it doesn't. DAMNIT!

But, yeah there you go. All answers appreciated.

No a 750ti will not bottleneck your system, it will work fine with your PSU, you have plenty more wattage.

Hope I helped

What's the exact model of your PSU? It's not exactly what it needs, but I recommend at least 30 amps on the 12V rail on your Power supply to make sure it can run all graphics cards.

Okay can you please keep this tab open for like 10 mins, imma check my PSU.

Blade Mastr :

Your Wattage is completely fine, obviously a half decent PSU would be better maybe a Corsair series PSU, Seasonic or Antec as it's likely that a generic PSU will fail eventually.

750TI runs from the PCIE

pcgaming98 · Mar 4, 2014

Wattage alone isn't what determines what allows him to run a component. One of the most important things to a PSU is Amperage, and Max continuous wattage output during load. That's why I want to know what model his PSU is. It's like getting a 500 watt PSU from an unknown maker that can only deal 25 volts on two 12V rails, that's not enough to run some graphics cards, but the graphics cards will say 500watt power supply minimum.

If you currently are running a GTX 660, you will be fine with a GTX 750 ti..But I would not say that would be an upgrade performance wise. I doubt you will see any positive difference other than power usage. I just got the 750 ti to play around with and I dont see any difference from my GTX 660.

pcgaming98 :

He already runs a 660 so he will be fine to run a 770...

IRyannHD :

Not all of them run on just the pci, the ASUS 750 ti requires a 6 pin PCIe cable.

Except he's listed the one he want which runs off the PCIE.

How can you tell, that link just took me to the evga site..some evga 750 ti's do some dont.

Well that fact it takes you to Evga tells me that it runs from the PCIE as the Evga 750TI runs from the PCIE although I'm not sure about their double fan models.

larrym · Mar 4, 2014

yea, either way, since he is already running a gtx 660, he will be fine.

Is this an XPS 8500? Last time I checked Dell was the only OEM that offered such a combo (3770 non-K, GTX 660 OEM).

No one has brought up the most important issue; Dell's motherboard (or maybe HP or whatever OEM you have) may not be compatible with the 750 Ti. Don't ridicule me like others before have done, http://en.community.dell.com/support-forums/desktop/f/3515/t/19474677.aspx clearly documents the trials and tribulations that 8500 owners like myself have experienced. However, I have already replaced the Dell motherboard with a retail one and reinstalled Windows, so it's not a problem for me.

As for power, you should be fine given the BIOs and motherboard aren't giving you issues. OEM psus are complete garbage; the XPS 8500 has one of the better OEM psus on the market and it can still only deliver 385W out of a claimed 460w on 12V, which is spread out across 3 different 12V rails. However, with the exception of the Asus 750 Ti, all other 750 Tis draw their power solely from the PCI slot and don't require any power connectors; if Dell felt that the GTX 660/HD 7870 can run on a 460w PSU, you bet that a 750 Ti will without any difficulty.

EDIT: if you are really paranoid, you can just swap out the OEM psu for a new one (I would say a TX-M/HX from Corsair or a G series/S12G/S12II from Seasonic would be your best bet for a reliable PSU).

I think he will be fine, power wise he is fine, he don't need a 6 pin power connecter and it will work most likely as he runs a 660.

Okay guys I got my PSU specs.
Here they are:

DC OUTPUT: MAX OUTPUT POWER 460W

+12VA -- 18A, +12VB --- 16A,
+12VC --- 8A, +3.3V --- 17A,
+5V --- 25A, -12V --- 0.3A,
+5V AUX ---3.0 A
+5V AND +3.3V Shall not exceed 142 W
+12VA, +12VB and +12VC Shall not exceed 385w

There, now what is your guys' opinions?

IRyannHD · Mar 4, 2014

Blade Mastr :

We've established that you're fine, you run a 660 so power wise you're fine, you don't need a 6 pin power connector and because you run a 660 your motherboard can support the 750ti.

Since they said it doesn't pull any power from the connectors, I guess you're in the clear.

Oh man if you guys are right. YES! Just to tell you guys, if I actually buy the 750 Ti, that will be my first graphics card buy. I'm getting so excited!

Ok, so we all say it will work..Im just not sure you will be happy with the result over a gtx 660.

IRyannHD · Mar 4, 2014

I personally would save up or chip out for a 770.

Will the new GTX 750 Ti work on my system?
