I'm thinking about buying a Nvidia GeForce GTX 750 ti for some light gaming and altcoin mining (specifically dogecoin), however I'm not sure if my PSU can handle it. Nvidia have said that it can run on a 300w PSU but the EVGA model that I want to buy is said to require a 400w PSU with 20 amps on the 12v rail. Here are my PSU specs.

The rest of my pc

CPU: i5 2320
GPU: integrated
RAM: 4gb
Hard drive: 500gb (5400rpm)

The PC was premade so I expect the PSU is of cheap quality, also because the new GPU will be used for altcoin mining my pc will be on almost 24/7

Thanks

i bought a zotac GTX 750ti 2gb
i installed in my pc and it run stress test without any problem

My psu is Liteon PS-6301-08A 300watt PSu and on the sticker it write

DC OUTPUT :+5v --/20A MAX
:+5v(SB) --/2A MAX
:-12v--/0.5A MAX
:+3.3v--20A MAX
:+12V1--10A MAX
:+12v2--13A MAX

1)Combined Power on +3.3v and +5v rails Not exceed 130w.
2)Combined Power on +12v1 and +12v2 SHALL not exceed 20A
3)At Ambient 25 Celsius total output power shall not exceed 300w
4)At Ambient 50 Celsius total output power shall not exceed 270w



My PC has the standard setup below :
WINDOWS 8
Intel Core i7 processor 3770
nVidia GeForce GTX 750 ti
1TB Hard Drive
8GB DDR3 memory
DVD-Super Multi drive
Card Reader
1 fan for the case

i assume that my i7 3370 have a MAx of 90 Watt TDP and GTX 750 TI 70 watt TDP
(90+70)÷12=13A

i have 2 rail 10A +12V and 13A +12v

by the way 300Watt -(90+70+50)watt = 90 watt left
the 50 is the max voltage i think will draw from other components

*BUT THE ABOVE IS ONLY MY OPINION
i am not responsible on your action/decision !

Sorry for this very late question, but how is it now? I happen to have the same PSU as you and I bought the GTX 750 and I'm not sure whether it'll blow up or not. My CPU has a max of 65W TDP as well.
