I was planning to connect an ancient HP Compaq dc5800 SFF workstation to the TV.
It currently has a Pentium E5400 with awful integrated graphics.
I was thinking about upgrading the CPU to Core 2 Quad Q9400 and add a 50$ GT 710 2gb GDDR5: https://www.amazon.com/GeForce-GDDR5-Graphics-Graphic-GT710-SL-2GD5-CSM/dp/B073GF2CL6/ref=psdc_284822_t2_B074Q4QF4J
This is the build: https://pcpartpicker.com/list/XT3h9N
As you can see it is 133 watts. My PSU is 240w, but, this is how it is distributed:
5.08V: 17A
3.33V: 15A
12V: 7.5A
And I think that CPU and GPU both take from the 12v rail, which in my case only has 7.5 amps.
And the Core 2 Quad Q9400 is 95w, meaning it uses (95/12=)7.9 amps , and the GT 710 is 19w so it draws extra (19/12)=1.58 amps for a total of 9.48 amps ,
that's much higher than the 7.5A on the 12v of this PSU
But maybe my calculation is wrong and the do not necessarily use the 12v rail only?
*And if my upgrade is not compatible with that PSU, is there a different upgrade you suggest?
Thanks
