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 :( 

Cheers

What make/model is the new PSU? Also, why not just exchange it?

I would be surprised if the Xenta actually put out as much power as your 300w PSU. I would return it or replace it. Get a quality Seasonic or Corsair PSU.

Good luck!

With PSUs, you get what you pay for. While some folks may have reviewed it well, that doesn't indicate a quality product.

Good luck!

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.

I lost a whole system to a cheap PSU.
Lost:
7900gx2 gpu
16gb gskill ddr3
2x 6 core amd fx 6100's (1'st one taken out by PSU, second by ruined Mobo)
2x ASRock 970 pro3 mobo's.

So, from someone who learned the hard way, spend the extra cash on a quality PSU that won't take the entire system out when it fails.

:lol:  :lol:  :lol: 
" had it a month it's great "
" has enough connectors, including a pcie "
Yeah, real good reviews

27a on the 12v, 2 x sata , 1 x 6 pin, it's a 380 watt psu, maybe

Less expensive than a CIT pos, now that's saying something, and it ain't good

Ouch 27a on the 12v is only 324w ... love how some companies rate their PSUs based off peak and not continuous great way to rip off uninformed customers!

I'd a closed my shop too, if I managed to unload a pos unit
like that.

A lot of folks listed quality brands in your earlier thread,
and you went n got this, looks like we are wasting our
time trying to help you.
