Right so i have just been down to my local computer shop and picked up a 550w psu for my new 7870 and he threw in another molex to 6 pin adaptor because i needed that specifically and when i got home plugged it in (I have done this many times before) and the pc just wouldnt power on... after a few tries of unplugging and replugging in the wires i gave up and plugged in my old 300w psu so cant use my new 7870 that i got yesterday
What can i do to check if its the psu? or what shall i do to fix i wanna play crysis 3
Yesss, so, basically, this was all explained to you in your previous thread.... it seemed that was pretty clear that you need a decent PSU. Also, some reviewers receive incentives to give positive reviews, doesn't mean the product is actually quality.
If you can't spend an extra ~10-20 on a decent PSU then don't use your 7870 till you can... You are trying to put a very low quality cheap PSU in your system that does not have the specs to run your hardware... By trying to save a few bucks you are risking your whole system being taken out.
