I just want to see if this card works and I only have my older eMachines desktop PC to test it on. I will keep the case open on the old emachines when I test it (it's a slimline.) It says it supports Low-profile cards due to the PSU (which I will address later on in this.) Long story short, I just recently built a new computer and computer beeps, but I'm getting no display on my monitor. I just recently had to Upgrade the Bios on the motherboard so that it would work together with my CPU and now the new PC beeps which is a good sign that the motherboard and CPU are working as they should, but no display. Keep in mind that I just got this GPU and I have no idea if it works to begin with. One of the fans on this GPU doesn't work. The card is a refurbished card and I assume that the previous owner may have overclocked and messed it up somehow and now it won't work any longer. I have an EVGA 500W 80+ Bronze Certified ATX Power Supply from the new computer and I was going to use the plug in cables from that to plug into the card just to test it on eMachines older PC. Is it ok if I just use those two power cables from that PSU to test the GPU on my older pc? Keep in mind that all the other parts on my older eMachines will still be connected to my 220 watt power supply. So can I test this card out by doing that on my older eMachines?Thank you for any help.
