Is My PSU Can Run Asus GTX 750ti OC Edition?

Ahmed Gamer · Jul 27, 2016

I'm looking to buy Asus gtx 750ti for my pc.

Pc spec,

PSU : 365w hp psu
Cup : Intel Core 2 duo e8500
Motherboard: hp 3032h
Ram type : DDR2

My psu :

Can my pc run gtx 750 ti?

Please help!

Ahmed Gamer :

no, it is too weak and does not have a 6-pin pcie cable

you need to make sure whatever 750 ti you buy does not need a 6-pin cable from the power supply

That model is not available in my country bro, I have calculated watts that my computer using it's near 250 watts with gtx 750 ti and my total watts is 365 but I don't think it's correct maybe because I have calculated watts for the first time. And about 6 pin, I can buy molex to 6 pin connector. And gtx 750 ti requires 5 amps .Thanks for replying!

adapters are 99% of the time very bad ideas
can you get a low profile version of the 750 ti or low profile 950?
or even better a new psu

never use adapters with crap power supplies

any model will work as long as it does not need an additional 6-pin power connector, that was just an example

nope no low profile gtx 750 ti available in my country and i have calculated my psu watts and usage, in case of watts= volts x amps and my watts are 511.48 using this method, about usage its 251w with gtx 750ti.

Do not assume that your power supply can provide the needed 365w total output. Especially if it's a few years old. A typical power supply can lose quite a bit of it's output as the capacitors inside age. The typical "heavy usage"/"old age" scenario assumes over 20-40% of output lost. I'd personally recommend upgrading the PSU before considering a GPU upgrade.

A simple Volts x Amps = Watts equation does not take in to account the internal limits of the power supply. On the label it states that the combined power of the 5V and 3.3V should never exceed 160w and the total output should never exceed 365w. Assuming a worst case scenario, you're left with ~205w. The "+12V" rail supplying power to the components (hard drives, cd drives, lights) and should be capable of <144w. The "CPU" +12v rail is capable of providing <174w. Given that this amount is used to power the CPU, motherboard, and motherboard-powered components (including GPU) you must determine if it is providing enough. The GTX 750 Ti will need <75w at full load on it's own. Factor in the motherboard requiring <=30w (Greatly depends on components and motherboard, could climb to as much as 200w) and the CPU using ~65w. This leaves you with ~79w overhead for the GPU. This should be just barely within the limits of the PSU.

The only issue is the age of the PSU. This system appears to be quite old (judging by the parts) and that age may become a problem. To be on the safe side I have to say: No, your PSU cannot run a GTX 750 Ti.

And about the age I will say old is gold!
For prove I have a 30 years used air cooler but it still works excellent just like new, prove 2 : I have a 20 years old tv too but it's graphics is better than Samsung led!

And thanks for replying.

oh ok it should run fine

compprob237 · Jul 30, 2016

Like I said, you're just barely within the output that the PSU is capable of if you include a GTX 750 Ti that has no extra power connections. I made some assumptions about your components and you've basically confirmed them with your recent post as well as the pictures. You can try it but don't be surprised if you have to replace the PSU eventually.

Also, the comparisons of old electronics still operating are irrelevant. The only way you can know if I'm right is if you hook up a volt-ohmmeter and oscilloscope to the output leads of the PSU and provide a load for it. Using this equipment you'd be able to determine if the PSU is operating properly. My guess is that, given it's age and the component quality, it is not operating quite as well as it did new. This slight variance in output could be enough to cause it to fail or kill the components attached to it.

I don't want to bore you with the details but suffice it to say that I don't feel comfortable stating that your PSU can handle the GTX 750 Ti. On paper it can, but in reality I'm uncertain. This is why I do not recommend you purchase it. Although, if you replace the PSU with a new 400w then I would happily recommend it!

Sorry I was goi to pick u best solution but accidentally clicked on epicness has solution.

i mean fine specs for the game not running the card
a asus 750 ti is still a bad idea on that psu
hit the unselect current solution button

Ahmed Gamer · Jul 30, 2016

sorry for the mistake but everybody knows who has the best solution.Bye, thanks for helping

I have found Asus gtx 750 ti oc edition tdp! It's max tdp is only only 60w,crazy right?

Epicness937 · Jul 31, 2016

Ahmed Gamer :

i guess just try it if you really need it i highly recomend against running that card
also why can you get a new psu?

Ahmed Gamer · Aug 1, 2016

Epicness937 :

First of all I think it can run on my psu and second of all didn't have so much money because I have to buy 2 sticks of 2gb ram and gtx 750 ti with molex to 6 pin connector. But I will still try to get a new psu. I'm looking at a 480watts psu have 18a on 12v but it is old psu too unfortunately thing in my country comes 5 to 9 months after the original release.
