Is this psu gonna work with gtx 750 ti ?

theunknownonex25 · Dec 25, 2017

Hey,so... i want to know if this psu : spacer 450W Sps-atx-450 is going to work with a gtx 750 ti with 2 fans.
I know ,i know its a poor psu and thats why i want your answers...
And my pc specs are: i3 4130 3.4ghz,8.00GB Dual-Channel DDR3 Ram,motherboard : ASRock H81M-DG4 (CPUSocket) with pci-express,storage: 465GB TOSHIBA DT01ACA050 SCSI Disk Device.

care to tell the GPU model?
most GPU with 2 fans requires up to 150W, meaning You need additional 6pin power connector to GPU

check if the PSU have the 6pin power connector (tho most new PSU have one)

other than that, i suppose 450W is enough, or 500W

bignastyid · Dec 25, 2017

I wouldn't use the PSU in any system, it's garbage. With a 16a 12v rail it's closer to a 200w unit than a 450w unit. A decent 450w would easily be enough, even a good 350w psu would be ok, but unfortunately what you have is a very poor quality 200w psu.

The specs for that PSU indicate a PSU design from 17 years ago (i.e. ATX12V v1.0).

theunknownonex25 · Dec 25, 2017

I just wanna know if the gpu works with this psu please someone answer

theunknownonex25 :

You still haven't posted the specific brand and model of the graphics card.

theunknownonex25 · Dec 25, 2017

MSI GeForce GTX 750 Ti GAMING Twin Frozr IV OC 2GB DDR5 12 or the asus gtx 750 ti ... an answer would be great

Yes 450W is more than enough for a 750ti. btw 750tis can easily run on 300W PSUs too.

theunknownonex25 :

That graphics card draws a maximum of 74 Watts during FurMark GPU Stress Testing. That card also doesn't have or require a 75 Watt 6-pin PCI Express supplementary power connector.

Based on the CPU that you are using you need a power supply unit that has a maximum combined +12 Volt continuous current rating of 15 Amps or greater. Your spacer 450W SPS-ATX-450's +12V current rating is 16 Amps so you're pretty close to the edge. This is assuming that the spacer 450W SPS-ATX-450 is actually able to deliver 16 Amps continuous.

Don't overclock anything. It is up to you whether or not you want to risk your system with that power supply unit.

By using your current PSU you'd be gambling with the life of your system. Your current unit has the potential to fry the entire system. I advise replacing the PSU first. But ultimately the choice to gamble is up to you.

If the spacer 450W SPS-ATX-450 is actually able to deliver at least 15 Amps or more continuous on its +12V rail then it should work. Most of the power consumed by your system will be from the +12V rail.

Thanks for all your help

And 1 more thing,do i need a 6 pin connector for a 2 fan gtx 750 ti ?

bignastyid :

And what psu would you recommend me to buy for a MSI GeForce GTX 750 Ti GAMING Twin Frozr IV OC 2GB DDR5 12 ?
A not so expensive one.

ko888 · Dec 25, 2017

theunknownonex25 :

Where (i.e. country) are you purchasing the PSU from?

bignastyid · Dec 25, 2017

theunknownonex25 :

Depends on where you are for the US I'd recommend one of these budget units.

Would this be a good one? Inter-Tech Energon 650W ?

bignastyid · Dec 26, 2017

Never seen a good inter-tech PSU and that one is no exception.

bignastyid :

But what about this one : nJoy Ayrus 450, 450W ?

gigantusmagnus · Dec 27, 2017

bignastyid · Dec 27, 2017

theunknownonex25 :

Almost as bad as your current unit.
