Hello Everyone,
I recently bought a new ATI 5870 Radeon Card to replace my old 9400GT. However, after installation, I noticed that my computer was constantly rebooting (the whole computer was crashing) and I was also recieving lower framerates that I expected in some of my games. At first, I was stumped on what was causing this...but I think I have an idea of why my new graphics card is not preforming well.
First of all...here are my specs:
4GB DDR3 1333MHZ
1GB GDDR5 ATI Radeon HD5870
AMD Phenom II X4 2.8ghz
600W Extreme Cooling Power Supply
1TB SATA 3.0 HDD
I double checked the power I needed for my 5870 and it said 500W minimum....so that was fine as it is under 600W. I then checked the total minimum ampage required on the 12V lines...which was 40. Well, after searching my house for my retail power box, I found out that under the +12V1 and +12V2 DC outputs it says that it has a maximum output of 18A each. (Assuming A stands for Amps?) This would only bring out a maximum output of 36A, which is obviously less than the minimum required for the 5870.
Is this the problem to why my computer is constantly rebooting/crashing? I thought that it might of been a problem with the power supply if the entire computer was being affected...if it is the problem, does anyone know a decent graphics card under 36A that can run games pretty well? I was looking in to the 5770 which I believe needs only 450W and a total of 34A on the 12V lines...however I am not sure if this is the best card I can get for my PSU... and I do not want to really dish out any more money on another Power supply
Thank you!!
