PSU for GTX 750 Ti

[Raminlich]

Hi,
i have this PSU:
http://pasteboard.co/5nlpC4NO7.jpg

and this is my specs:
CPU : Intel Corei3 4170
MotherBoard : Asus H81M-V3
Storage : SeaGate HDD 500 GB
RAM : DDR3 2GB + 2GB

I wanted to buy MSI GTX 750 Ti OC V1 2GB GDDR5

but im not sure if my psu is enough.
i have checked in msi power calculator website it says enough.
i have also asked another guy told me that my psu is enough.
but i still not sure.
Here is result i get on msi power calculator:

So what do you guys think?
Thanks

Buy a well known brand PSU.

Where do you live if your looking for deals?

 

[Raminlich]

Buy a well known brand PSU.

but i thought memonex was fine brand!
so will be 300W with well known brand enough?(because im so tight on budget)
and what brand do you recommend?
Thanks

So all of this power calculator sites are useless?

 

[Jetster]

Is it a OEM PC? And where do you live?

Its not a matter of the total power its the 12v rails

Its not OEM i think , i live in iran

Its not a matter of the total power its the 12v rails

and what you exactly mean with this can you explain it more clearly im little new in psu things.
Thanks

Its not a total of 280 watts. Its 195 Watts split on two 12 volt systems. Now it would probably power it up but as soon as you start to game it may have problems or fail.

No. They all are better than guessing, or just pulling arbitrary numbers out of thin air. But they all tend to be a bit generous in their recommendations, but that is a good thing. It is MUCH better to buy a little too big than too small. Note the card makers always pad the results too because they don't know the other components you will be using with their cards. Your i3 and 2 x 2GB of DDR3 are not very power hungry so 400W technically more than you need.

I only recommend the eXtreme Power Supply Calculator to determine your minimum and recommended power supply unit (PSU) requirements. They are the only calculator people that factor in specific CPUs, RAM, fan speeds, drives, etc. and break down all the specs per rail, and more. But like any calculator, you need to know what to put in it to get the right information out of it.

Plan ahead and plug in all the hardware you think you might have in 2 or 3 years. This might include extra hard drives, a bigger or 2nd video card, more RAM, etc. I recommend setting Computer Utilization to 16 hours per day and CPU Utilization to 100%. These steps adjust for capacitor aging and ensure the supply has adequate head room for stress free (and perhaps quieter) operation. These steps also add a little buffer for unplanned future upgrades or added hardware demands.

Technically, a good 300W supply will support your needs. The problem is, most PSU makers reserve their better quality components and design for their higher power PSUs. So I would look at 400W minimum - and one that is 80 PLUS certified Bronze or better.

As far as the 12V rail, that is often considered the most important because that is where the main power is to drive graphics card and other major components. That said, a good clean 3.3V and 5V are just as important.

As Jetster noted, your supply is a multi-rail design. This means it is splitting up the 12V on 2 rails. If it were a single rail design, it would be large enough.

Hi,
i have this PSU:
http://pasteboard.co/5nlpC4NO7.jpg

thow it away ...

and this is my specs:
CPU : Intel Corei3 4170
MotherBoard : Asus H81M-V3
Storage : SeaGate HDD 500 GB
RAM : DDR3 2GB + 2GB

fill this! will all complete specs!

also as many others have said, a decent 350W or 400W could fit your needs,
so we higly recomend you something like Seasonic, Thermaltake, antec and also Enermax, those brandes have pretty great PSU's,

Regards,

Get cx430 or something of that level.

(We get more questions about GTX 750's and PSU's. Ironic, no?)
If that is a decent PSU, it should work. Of the (advertised) 195 watts on the 12 volt rails, the CPU uses (up to) 54 watts. With all of the other items in the computer, I'd think that more than half of that 195 watts is available for a GPU. And GTX 750's only use about 60 watts.
OP, are you using a GPU now, or just the iGPU?

 

[Kanan]

Try the pc with that psu if it works it works if not replace the psu. I don't see a sense in replacing the psu that is probably enough for powering that low power system, if you're low on money.

because its a wonky PSU lad, take a wathc do you at least see the 80+ badge?

its a time bomb using generic PSU's

 

[Kanan]

I'm not sure it's wonky just because it lacks 80+. 80+ isn't really relevant on low power psus. Question is if the psu is of good quality or not. Because it's low power I tend to believe it's okay. The psu bombs are usually the "500+" watt units.

not always, i have seen 300w wonky psu failing, also some of then ends like popcorn... because of overloads and sh*t....

i have the MSI Low profile 750Ti running on a SFF dell optiplex 7010, and has been for about a year just fine...iirc its 240Watts.. it is also running a i5, and its never had an issue.i installed it to beef up the workstation, and it kicks ass for what it is.

just to be clear. i dont recommend this configuration if You have the choice for more Wattage, it was just me adding HP to a decent PC that has ZERO room for expansion, without going into a new MB, Case, and PSU etc....if your going from ground up, go higher wattage.but iirc this thing run like 80watts, to 125 during normal use..dont quote me tho

this is the 750Ti i have

Minimun 400W Power Supply from MSI website Like what @Jetser said

Those "minimums" are pure BS, manufacturers just say that in case someone puts a graphics card with a cheapest no-name crap PSU.

Years ago I ran a HD3870X2 with a heavily overclocked C2D E6400 on a HEC 300W PSU without problems, later upgraded to 1GHz+ overclocked/overvolted HD4890, and it also ran without any problems. I also had this G3258 @ 4.5GHz with an overclocked Radeon R9 290 running on a XFX TS 430W PSU, and again, no problems at all.

GTX750Ti's TDP is 60W and by default it doesn't need any external power, though some models have 6-pin PCI-e connector, mostly for overclocking. Of course OP's PSU is crap, but saying things like "minimum 400 Watts" may lead to someone think that a high quality Seasonic G-360 isn't enough..

I answered before reading i concur totally.

Manufacturer recommendation are overboard, PSU calc are not useless, but a good "approximate" and more often closer to reality than manufacturers recommendations.

160W was enough for a i3-4130T a gtx 860m (mobile 750Ti that can be clocked back to the same level.) 2x4gb 1600 and a sshd 1tb+8gb

Another example: Asus recommended 700W for a single 580, i ran 2 in SLI on a quite heavy configuration with a good 700W 80+ gold

 

[Kanan]

Asus recommended 700W for a single 580Ti,

New GPU? I think you meant the 580 haha.

On topic: as I said, make sure the PSU is crap, before buying something new, not much sense into rushing things.

I had to check about my old HD5870 Vapor-X..

600 Watt Power Supply (Suggestion)
900 Watt Power Supply is recommended for CrossFireX™ System

I ran two of these overclocked, CPU was i5-2500K @ 4.8GHz with heavy overvoltage, PSU was XFX 650W and no signs of unstability.

 

[Jetster]

And what so you think he has? Besides the difference in cost from a 300w to a 430 is nothing

 

[GreiverBlade]

Woops nope I meant Asus GTX 580 Matrix Platinum which is almost like a 580Ti compared to the standard 580 peasant edition joke (I had 4 580 2x Matrix platinum 1x zotac ref and 1x EVGA ref )

 

[Kanan]

Edition: extra power hungry. "Thermi" was really funny, I can't get that 590 out of my head that smoked under light OC.
