How long have you had your Antec TP3-550? It was introduced in 2006, and sold apparently until 2009. So minimally about seven years old.
Let's look at the specs on this PSU itself and see what we find:
![]()
While it shows 18A maximum for each of the three +12V rails, we can see below the main specs that the total of the three +12V rails at the same time has a maximum load of 42A.
That is not quite the simple total of 18A x 3 = 54A.
If we assume an equal load distributed on each of the three +12V rails, 42A / 3 = 14A or 168W per rail.
If the PCIe power cables are wired with one on each of the three +12V rails, or two on two of the +12V rails, then it might be possible to power the video cards fine with this PSU. That wiring would make sense, but is an unknown.
Next, note that a total power output of 42A from the three +12V rails, is 42A x 12V = 504W. That leaves 46W for the load on the +5V and +3.3V rails combined.
Finally, we have not yet taken into account the +12V power needs of everything besides the video card. That is the CPU, HDDs, fans, mother board, etc.
Regardless, with the correct connections, you can (and have) get by with using the GTX 560 with that PSU. That is because you aren't constantly using the card at full power.
BUT, you are stressing that PSU to near or at its maximum capacity while gaming. The 7870 can use even more power.
Your GTX 560 may be artifacting because it is not getting enough power. That card may not be failing, but the PSU is instead.
Checking the 7870 for missing parts is not a bad idea. Look for damaged or burnt parts too. Also, memory chips, the GPU chip itself, and others, may be bad and show no signs of damage.
I just looked up 7870 cards for sale, Used, on Amazon. None were less than ~$150. Given what you paid, I hope it works.

I had the 7870 tested and it wasn't giving a signal to the monitor on their test bed anyways I'm about to go over it with a magnifier glass and see if anything is missing. I am determined I to use this 7870 |
