Currently have a 420 Watts Power Supply

was wondering if i need to upgrade to a better one, since it feels like my GPU it's not being used at it's full potential? (sometimes lags playing 1080p youtube videos..)

I have a GeForce GTX 750Ti , and i honestly don't feel like it should be doing that, i also researched a little and look up that it takes 200 watts to run if i am correct?


    300 watt or greater power supply required


Really feel like i should't be lagging while playing 1080p videos on youtube sometimes.
i also don't think that playing a video in the background while playing league in window mode should make me drop FPS, because my integrated GPU (Intel 4000HD) could of done it easily, without dropping frames,

yea i would suggest you upgrade the psu to this one as it is relatively cheap http://www.bestbuy.com/site/evga-bronze-power-supply/13... power supply&cp=1&lp=1#tab=buyingOptions

I think your problem is elsewhere.
Your card is powered entirely by the motherboard pcie x16 slot. That is 75w max.
Other parts will not add up to much hence the 300w requirement.

What is the rest of your system.

a underpowered card could cause the card to perform poorly . get a the psu recommended then it will have sufficient power

I think the link to the case is dead, other than that that's my build.

Yeah i was gonna buy the one you just recommended me, question do i ahve to uninstall my motherboard to uninstall the PSU? or not?

you dont have to remove the whole motherboard for the psu but if you want to be really safe then i suggest you remove the board first as you might accidentally drop the psu onto the board

A psu change is relatively painless, but in my opinion not necessary.

I see two issues with your build.
1. You have a H77 based motherboard You need a Z87 based motherboard to be able to raise the 3570K multiplier and reach it's full potential of perhaps 20% faster.

2. 4gb of ram is too small. You should be at 8gb for most usages.

I guess that build is kind of outdated, i do have 8 GB of RAM.

and this is the motherboard i use,

Thank you , i think i might install it without uninstalling the motherboard i feel like i might be break it in the process of uninstalling it.

If you want a new psu, it is easy to change one out without removing the motherboard as a rule.
In some cases, the 24 pin and 4/8 pin motherboard leads are tight fitting and restricted space may make it hard to remove them.
Still, I see no need.

A Z77 motherboard leaves 20% cpu power on the table. I would change that to z87 and oc your 3570K first.

dont mean to sound disrespectful or anything but did you even bother to ask the guy if he wants to change the motherboard in the first place ? your suggesting he buys a new motherboard for x amount of dollars and then he is still going to buy a new psu in the process .. dont you think thats more spending than what he is asking about ?

mr juniiflow do you have enough money for both upgrades ?

Nope.

Also what do you mean by it leaves 20% CPU on the table? and no, i don't really want to Overclock my CPU.

it means the motherboard enables the cpu to perform at its full potential .. through overclocking by the way which you just now ruled out of the question.. go for the psu upgrade thats my suggestion

My point is that even a 300w psu should be able to run a GTX750ti.
I see no point in upgrading a psu to a stronger unit that will not impact performance at all.
Better quality... yes. Future graphics upgradeability... yes. But to improve the current graphics performance, I don't see how a stronger psu will help.

A stock 3570K runs at a multiplier of 34.
If you have a overclocking capable motherboard, namely a Z77 based motherboard, you can raise that multiplier significantly into the range of 40-45. That is a improvement of 15% to 30% in cpu capability.
You do need a adequate cpu cooler, and the upper limit is determined by your luck in getting a good chip.
Intel sells the "K" suffix cpu's with the intention that the user will raise the multiplier(AKA overclock).
So long as you leave voltage settings on auto you are safe. The cpu will downclock or even shut off to protect itself if it gets too hot.

My bad on saying Z77 restricts your options. I was thinking Z87 which is for haswell. For ivy bridge, Z77 is fine and does allow overclocking.
If the op wants better performance, and if cpu is the limiting factor, then he should try a mild oc to perhaps the 40 level. That will work even with the stock intel cooler.
I would test with OCCT and gradually raise the multiplier one step at a time until the temperatures stabilize at around 75c.

I can understand being nervous about this, but overclocking is exactly why there is a "K" chip.
