Good evening, I'm a bit confusing for a videocard that can run well on my PC. I want to buy a videocard to increase performance on HD videos, cinema, etc and maybe a bit for old video games.
I understand the main things to have in mind is board compatibility and needed PSU. My PC is 4 years old and it has and ACER 946GZT-AM V.1.0 motherboard, comes with PCI-e 1.1 which I believe PCI-e 2.0 cards are compatible.
The rest are:
-Core 2 Duo E4400 @ 2,00 Ghz
-1x2 GB Markvision RAM
-Delta Electronics DPS-250AB 250W
I put an eye for the ati HD5450 or nvidia gt210, which I like for the cheap price and well performance for cinema, any other upper than these require more than 350W I think.
I research on forums and some says that HD5450 can perform well on a 250W PSU, others says at least 300W is needed.
Please I beg for help here, any suggestions is appreciated, if I should change the Power supply I will do it, but I want to know if I won't have problems with this HD5450 on this board.
Well as @ct1615 said your psu should be fine, and I noticed you decided to get a bigger one, and that does indeed open up some doors to what you can get. What is your budget for getting a graphics card?
Our test system is a power hungry Core i7 965 / X58 based and overclocked to 3.75 GHz. Next to that we have energy saving functions disabled for this motherboard and processor (to ensure consistent benchmark results).
Our motherboard also allows adding power phases for stability, which we enabled as well. I'd say on average we are using roughly 50 to 100 Watts more than a standard PC due to these settings and then add the CPU overclock, water-cooling, additional cold cathode lights etc.
Keep that in mind. Our normal system power consumption is much higher than your average system.
Single GPU 5450:
System in IDLE = 154 Watts
System with GPU in FULL Stress =177 Watts
Difference (GPU load) =23 Watt
and finally techppower up states you will use 9w for video playback and a mind blowing 13w during gaming. i can't imagine they make PSU powerful enough to run two of these bad boys in CF...
