When i installed the dvd drive my computer would hard restart every so often and cause my bios to reset my overclock settings that were stable without the drive. I am no expert but i assume this is signs that my current PSU is either dying or can't handle the power. I uninstalled the dvd drive before testing the 5770.
After uninstalling my old 4670 and installing the 5770 vapor-x that also caused my computer to hard restart and reset my bios settings. I can't get the 5770 to boot. The lights and fans work but i get a black screen (yes the 6 pin was connected and the card is properly seated). Sometimes i can see the bios load but once i get to the windows 7 splash screen it just hangs. When i install the old 4670 again everything works just fine. I have done a bunch of research and possible issues are older mb's having compatibility issues with pci-e 2.1 video cards or the PSU is not good enough.
I have started the RMA process on the 5770 just in case that is faulty but i would first like to upgrade my PSU to see if that helps. I would basically just like to know if the following PSU and MB are compatible with each other, and if the PSU will power the 5770 vapor-x. This PSU is within my price range.
ur old PSU seems to be the prob coz i don think it can run a 5770 .
if ur freind has a decent pC try running your card there.the gigabyte G31 mobo is a small board i wud spend a bit more for a g41 mobo anyway ur choice i had this mobo earlier worked gr8 with 9400gt.Dont expect too much OCing out of it. the PSU u linked to is of brand i havnt herd much of so i wont comment on it but i wud recommend something like corsair VX450 minimum for 5770 .i m running GTX460 with it and its an awesome PSU u can read review abt it.
"Where’s the 4-pin EPS/ATX 12v connector that I need for my motherboard?
Our power supplies ship with an 8-pin connector that splits in half. Use half of this connector for the 4-pin EPS/ATX 12v connector on your motherboard."
Do youself a favor and DO NOT buy Raidmax. The most important thing in your PC is the PSU because if it blows up it will take out all your other components with it. Buy a quality PSU from companies such as Seasonic, Antec, XFX, PC power & Cooling.
