Think I need a new power supply with 3 8 pin connectors, need advice please.

Chriski420 · Apr 4, 2016

Hi I'm new here, I'm having a bit of trouble.

I recently purchased a new Asus motherboard and a Sapphire Radeon GHz Edition 3gb and the motherboard requires 1 8 pin connector and the graphics card requires 2 8 pin connectors.

My 750w power supply has 1 8 pin connector, 1 6+2 connector and I have a converter to make another 8 pin so I managed to plug everything in okay.

It boots up fine, installed drivers no problem but when I open a game as soon as you enter gameplay the pc just turns off instantly, like on Witcher 3 I see Geralt on the horse for half a second and it shuts down.

After doing research I think it's down to the power supply, I was just wondering if anyone can recommend the cheapest power supply available that will be able run the graphics card.

What make/model is your PSU? Not all are created equally and yours may not be able to provide sufficient power to your total system.

Updated original post with psu picture.

Yes that is probably BECAUSE YOUR PSU is not sufficient.

Adapters are a bad idea with a poor quality PSU.

SR-71 BB is spot on. Your PSU is not up to the task. Time for a new one.

What is your budget and where do you purchase PC parts from?

I've already spent my budget as I didn't expect to need a new psu so I was just looking for the cheapest one possible that will run my graphics card and amd fx 8350, any recommendations?

I usually buy my stuff online in UK (where I live)

Dark Lord of Tech · Apr 4, 2016

I listed a Super Flower made 650w above on a UK site.

Chriski420 · Apr 4, 2016

SR-71 it looks good but do I need to spend that much to run it all?

Dark Lord of Tech · Apr 4, 2016

It's only a few £ more for the 650 , so it's the better deal.

Great warranty , solid upgrade , to run your system.

Chriski420 · Apr 4, 2016

Would a XFX 650w work with me needing 3 8-pin connectors? I can get one for £45 if so.

turkey3_scratch · Apr 4, 2016

You mean the XFX XT 650W or what one? I wouldn't get an XT. Anything else by them is solid.

Chriski420 · Apr 4, 2016

Xfx 650w 80+ bronze as Im low on money at the moment so any saving is good to me

I found this EVGA Supernova PSU for £62, it's got enough 8-pin connectors for your purposes. You should be fine with a 550W PSU.

Edit: I should add that it's a Tier 1 Gold PSU, so it's pretty good value compared to everything else in that price range.

Chriski420 · Apr 4, 2016

So I think I've narrowed it down but I just want to double check with people that they would be powerful enough

Corsair CS650M or Cooler Master G650M hybrid modular

Would either of these work with an 8 pin mobo and the 7970 HD?

Edit: Thanks Hyboria, if neither of these are compatible I think I'll settle for that one.

Dark Lord of Tech · Apr 4, 2016

Both can get the job done , but not great quality.

turkey3_scratch · Apr 4, 2016

Hyboria :

It should be Tier 2 IMO. Voltage regulation is not too good on it, and ripple isn't quite Tier 1-worthy,
