Would this GPU and power supply work in my current rig?

[ScoopSlam94]

Hi there, everyone. I have a Gateway DX4870 that I bought used at my local game shop sometime last year. I have a bunch of games on Steam that I can run, albeit with some lag and usually never at the biggest resolutions with my integrated Intel HD 2500 graphics. I was planning on upgrading with a decent graphics card at a budget price, so I chose the EVGA GeForce 750 Ti. My current power supply is only 300W with very little support on the +12V rails. The GPU requires at least 400W and also 20A on the +12V rails. I took a look at some power supplies on Newegg and found an "EVGA 100-W1-500-KR 500W ATX12V / EPS12V 80 PLUS" one. Now, first of all, I'm not sure this thing will fit. The PSU that's inside of my computer right now is an FSP300-60THA(1). I did some research on the measurements, and from what I understand, I should be able to fit the new supply in my computer. Can anyone please confirm this for me? Also, with the supply and the model of my computer, would the new graphics card work? Any help would surely be appreciated. Thanks in advance.

P.S. Here are the links on Newegg to the PSU and GPU I'm looking at:

What's the rest of the components in the PC?

That FSP power supply is thoroughly adequate, as they are one of the only PSU OEMs that actually make crazy inexpensive PSUs that don't blow up your computer.

A 750 Ti only takes ~70w of draw at absolute max.

Thanks for the reply! I ran a Dxdiag test for you:

Your PSU is +12V1@8A, +12V2@14A.

Your "Intel(R) Core(TM) i5-3330 CPU @ 3.00GHz (4 CPUs), ~3.0GHz" is not going to ever draw more than 77w, which is 77 / 11 = 7A (Calculated with high quantity of VDROOP just in case)

The 750 TI does not use more than 70w ever, so 70 / 11 = 6.36A (Calculating with high quantity of VDROOP.

Your PSU looks adequate as long as these are the only components with major power draw in your system.

Thanks again for staying with me. Now what would you consider a major draw from a PSU? I have a wired Afterglow Xbox controller and an Aula BeFire backlit keyboard hooked up via USB. Also a webcam that I never use, so if that takes too much, I can just throw that out. But would any of those things take a lot? I don't really know much about the guts of my computer other than the things I told you, but if there's any specific parts you want me to find out about (CD/DVD drives, etc), I can check them out really quick and let you know.

Forgot to mention that I also have a generic 1TB hard drive in my computer, as well.

Max total watts pulled by whole system was ~180. This is with an i7-4960X @ 4.2GHz, 32GB DDR3, basically a much more power-hungry setup than yours.

As said above, you got lucky with an FSP power supply in your box, those are surprisingly solid for OEM power supplies.

You'll be fine just dropping in the new 750 Ti. If the PSU doesn't have the 6-pin PCIe connector you need, an adapter should be included with card.

Well, that's pretty much all the information I need. Thanks a bunch to the both of you. I don't think the 750 Ti requires a 6-pin, does it? Also, I'm thinking of picking up a superclocked version of the card. I know it's no different than just buying the regular one and overclocking it myself, but do you think my system could handle that version of the card?
