Alright, so a couple of years ago I bought a pre-build pc. So far it's done the job, but always slacked a little behind on graphics performance. Then I saw an article about the 750 ti and how to would only require a 300w power supply to run. Which is perfect for me as that's what's currently in the pc. So I started doing some research and saw some posts like it won't work on a 12v rail blah blah blah. This made me doubt if it would run on my pc. After some more research I learned the the PCI-E can only deliver 75w, I then proceeded and tried a few PSU calculators with my system specs minus my current GPU and for the most part I got around 220-226. I know these can't be exactly accurate but it made me wonder. The 750 won't take more that 75w and these calculators estimate that I'll have roughly that amount of wattage left. Which once again made me curious if my system could run it.

Anyway my current system specs are
Processor: Intel Core i3 2120 @ 3300 MHz
Mainboard: MSI H61M-E23 (MS-7680)
Video Card: NVIDIA GeForce GT 430
Hard Disk: Hitachi HDS5C3020ALA632 ATA Device (2000GB)
DVD-Rom Drive: ATAPI iHAS122
Physical Memory: 8192 MB (2 x 4096 DDR3-SDRAM )
Power supply: LPA-300C
Here is a picture of the sticker on my PSU.

That just leaves my question, can my pc run a Geforce GTX 750 TI?


Thanks,

Solution
Amperage is what matters, not wattage, Dell tends to underrate their PSUs while others like these have overrated wattages

12 amps on the +12v rail means an output of 144W, I wouldn't exactly trust it
Im having almost the same problem. I was looking for a new graphics card and wonderd how much power does it use i find its 300W and im like cool aight. I order the Graphics card and itll arrive tomorrow. Later that day i started reading the texts on my power supply and i find out that my power supply is 350W boost and normally 286W. My question is that can my power supply keep the gtx 750TI going and whats the worst thing that could happen when im missing 14Watts.


Some advices wouldnt hurt me :)
Merry Christmas to every one :)

2 years i run my pc with a gigabyte GV-5670 (R567ZL-1GI) I was very good graphics card and good performance by seeing (not fps) but had to give back the gpu... and I never had a problem with the card....

Its not about watts look its only 12amps one 12v awful
 
So not true, I have an Acer Aspire MC605 that originally had a Radeon 7470 (9W TDP) and also had a 300W Delta Electronics PSU and 12A on +12v Rail, 13A on +12v1 rail and 15A on the +12v2 Rail and currently running a GTX 750 Ti without any problems except the PSU running a bit hot during heavy load(like a benchmark or something)
