Hi I have the following system HP Compaq 8200 Elite Small form factor Core i7 PC. Can I install the following graphic card in my system and my Power supply is not upgradeable.

Graphic card- Gigabyte NVIDIA GTX 750 Ti Low Profile Graphics Card - 2GB

My Power Supply is 240 w
+12v cpu - 16A
+12v main - 16A

my system spec is CPU - Core i7 2600 CPU @ 3.4 Ghz
RAM - 4 GB
optical drive - DVD drive
hard drive - ATA 500Gb
power supply - as stated above


My question is can I install and run this small form factor graphics card in my system. I read somewhere that this card requires 75 watts ( ie approx 7A on 12v rail) if this is true it will leave approx 9A for the rest of the system to run (ie CPU , optical drive etc) . Can I run this graphics card with my power supply. All answer would be greatly appreciated

Hi
That PSU will not work with 750Ti.
GPU power consumption 64W average but 140 W peak,you need to design the system for peak loads.
CPU power consumption 95W
Motherboard, hard drive, ram,optical and fans about 60W.
Which gives a grand total of 295W.
This is the absolute minimum size of PSU you could get away with ,but so you would not be driving the PSU flat out all the time and so reducing its lifespan and also to give some overhead then you would need something like a 450W or 500W PSU.
