Hi all,

Quick question here.

I want to ask whether this PSU would be okay to run a nvidia GTX 750ti (this one),

Here is my current PSU

My current Nvidia GTZ 745 (OEM) has a TDP of 55w, this 60TDP would be a 5w increase. This is an 80+ Bronze certified PSU (maximum 20a on combined 12v rail), would it be safe/sufficient to run the 750ti on this psu?

Currently I am running these desktop specs;

Windows 10 Home 64-bit
Intel Core i7 6700 @ 3.40GHz Skylake 14nm
RAM 16GB Dual-Channel DDR3
4GB NVIDIA GeForce GTX 745
3TB HDD 5400 rpm
PSU 300w

Thanks for any help with this!

You have written in your Title that its a 300W Power supply but in description its written that its a 220W power supply. Bro please be clear about you PSU's wattage. If its 300W then yes it can handle GTX 750ti. If its 220W then go for a better PSU.
Get this one it costs only 27$

Its not a overclockable i7 bro. Also its a 6th gen CPU and consumes only 54W. So i dont think 300W would be a problem as long as he is not overclocking the GPU

u r basing ur arguments with theoretical parameters...in real world scenarios it doesnt work that way...
i have sen many systems get fried due to confirming with specific hardware wattage...

Apologies about the conflicting information, the PSU label itself pictured above clearly states it a 300w PSU, however on the website where I bought the store it states this pc has a 220w PSU, so I went with the 300w label. I wouldn't be overclocking the GPU, and this one I want to get isn't a SC, OC, FTW etc. edition and would only be 5 TDP higher than the current GPU. I wanted to avoid upgrading the PSU if possible.

Even a system with overcloked GTX 750ti cosumes 196W, also his PSU is not a bad quality one, its a OEM PSU from HP. So he should be fine with it.

Thanks for the reply! I have read a lot more reports of people using the GTX 750ti on a 300w PSU (my PSU states it is 300W on the label) with no problems as long as it isn't overclocked etc. as you say, I do want to upgrade the PSU but for the meantime a small jump up to the 750ti would be better for me.

Sorry my basic Dropbox account isn't letting me change permissions so you can view the image even though it says anyone can view this link... Here it this specs of my PSU;

LITEON

Model No. PS-6301-09AB (can only find information on the PS-6301-08a on the internet). Although is it 80+ Bronze certified.

300W

DC OUTPUT

+12v1 - 10a max
+12v2 - 16a max
+5SB - 2.5a max
-12V - 0.3a max

Combined +12v O/P not excess 20a and surge 25a (I think a limit of 20a on the 12v rail would be sufficient?)

See, first of all Hellfire13 your PC fried because your Processor is a Haswell processor which has most of VRM on inside of the CPU and thus if proper ATX Power is not supplied then even little overvoltages can damage the CPU. This is not the case with 6th gen processors. And his 6th gen is not overclockable. Also iBall is a bad company, your PSU might not even provide the full power as mentioned on it. Whereas Lite-On is a brand of Compaq which further is a brand of HP. Lite-On makes OEM PSUs for many companies like Dell, Asus, MSI, Acer etc. Their PSUs are quite good and wont fail easily.

And neewru that link is not working because the provided link is not for public veiwing rather it will only be visible when we log into your account. You better upload the image on Imgur.com

i understand that Krishan...
point being...u dont only consider gpu wattage while buying a psu...u need to consider also the other hardware wattages which are collaterals...
and the psu has to add up with all the wattages and needs to give a little leverage to that total amount as well...
now...what i mean is...more often than not i have seen a lot of hardwares crash due to lack of power even being on par than not...its always convenient to keep a little headroom than to be at exact power requirement...
when u r at par, it is like 50-50...but if u exceed a little, it might give that extra bit of leverage...
and that G series V2 Seasonic 550w fried a 6700k...
hence my observations...
we are both right at our places...but its better to be practical than theoritical...atleast thts wat i thought...

Dont know about that i7 6700k frying case, it might be due to GPU or he may have some other problems.
And i checked Wattages of all the components in his Build which when put at full load wont exceed 192W of power. It will mostly hover around 160 watts while gaming sessions and around 20-30 watts when Idle. And his PSU is 300 Watts so we are getting 100 extra watts. Theres no way he will ever exceed the 220W mark.
