Can my PSU run a GTX 750Ti?

Can this offbrand PSU handle a GTX 750 Ti?
I heard something about the voltages and amps, but I don't understand all that. I was looking to get an mSi GTX 750 Ti Twin Frozr 2GBDDR5, or the 1GB one. Can it handle those aswell? And if no, what GPU would be good and not bottleneck the CPU.

PSU: http://prntscr.com/apexam
Processor: i3-3240 3400 MHz
RAM: 2x4GB

Sorry nope, the 750 Ti needs 20A on the +12V rail. You only have 16A

Refer to this list: http://www.tomshardware.com/forum/id-2547993/psu-tier-list.html

Do you mind giving me some ideas of which PSU to buy?

junkeymonkey · Apr 7, 2016

you could maybe look at 750ti cards that just run off slot power ?? some don't require a pci-e led from the psu or that extra power as do the 750ti's that do ..

300w is the recommended min on a 750 ti your still cutting it close

example no psu leds required just runs off the slot

I already did, anything in tier 1 of this list will be best: http://www.tomshardware.com/forum/id-2547993/psu-tier-list.html

The 750 Ti needs 300W and 20A on the +12V Rail...MINIMUM

junkeymonkey · Apr 7, 2016

and that goes for the cards that just run off the slot as well ??? seeing the slot is set at 75w max..

I think you talking cards that require extra power from the psu

see that 750 ti I linked is just a 60w card

now its big brother that need psu power is a 85w card so now you get that extra amp's requires

Amps = Watts/Volts so 60w card /12v psu = 5 amps ??

now your total system power 300w psu / 12v = 25amp

so why only 16 from his 350w psu ?? hmmmm........

my 850 states 70 amps so 850w psu / 12 = 70 as correct

In the past I have had, lets just say disagreements with other members, over what PSU can run a 750Ti. Everyone overestimates the power requirements. There are people out there with HP computers with a 220W PSU who are running a 750Ti just fine....none of them have ever complained that I caused them to blow up their computer.

I believe your 350w psu is overrated and not a true 350 w at 16a a 350 should be 27-29 amp

and why I say that 60w card or one like it I linked above that just needs slot power should be fine

A GTX 750Ti at stock clocks without a PCIe power connector draws about 66W max. Whether or not you can run it on your power supply depends on the rest of your system. The recommended watts from Nvidia take into account total system draw and are conservative.

FWIW, I've been running a GTX 750Ti with a 150W power supply with 10A on the +12V rail for over a year with no problems. I don't recommend going that low unless you know what you're doing, though.

kinda like it says in the cards footnotes

''****Minimum system power requirement based on a PC configured with an Intel Core i7 3.2GHz processor.
most time its full system power load not what the card uses

Amps = Watts/Volts so 60w card /12v psu = 5 amps cards draw
