Psu question

Hello,
I need to know if an xfx pro 550w core edition will be enough to power my system:

Intel core i5 3570k
Asrock z77 pro4-m motherboard
Corsair DD3 vengeance LP 1600MHz 8gb
Nvidia gtx560 zotac
Cooler Master tx3 evo
Sandisk extreme 120gb ssd
Xigmatek Midgard II case (2x120mm fans)

I don't plan any sli/crossfire or overclocking (not for now at least, maybe some mild oc in the far future).
However I'm keeping the GPU from my old build and I'm going to upgrade sooner or later so I need a PSU which can sustain a newer mid to high end GPU.

So, given these conditions, am I fine with the xfx 550?

Thanks in advance

  1. You should be just fine with the xfx pro550. It's a good 550w psu more than enough for most 1 gpu + i5 3570k oc'ed setups. Really only if you get a 7970 or maybe a gtx 680 then oc it the xfx probably wouldn't be enough.
  2. The PSU has one 6+2 pin connector http://www.newegg.com/Product/Product.aspx?Item=N82E16817207013 while the GTX 560 requires two six pin connectors http://www.geforce.com/hardware/desktop-gpus/geforce-gtx-560/specifications. You can buy SATA to PCIE pin adapter.
  3. you should be okay if you're staying in the 560 range of GPUs, but you're saying high end GPU, well, it will depend on how highend you wish get, at some point 550W might not cut it.

    A 6+2 connector gives you the option of connecting to a 6 pin or 8 pin so the op doesn't need an adapter.

    He could power a much better gpu than a 560. Almost any newer gpu would be fine. A gtx 660, gtx 660ti, gtx 670, hd 7850, hd 7870, hd 7950 would all be fine with the xfx pro550w. Even a hd 7970 and gtx 680 would be ok if he didn't oc them.

    Yeah I know, the PSU has ONE 6 pin connector. his GPU requires TWO 6 pin connectors.
  7. Thanks for the replies but... From the product's specs page it says the 550w has 1x6+2 pin and another six pin connector so it should be ok with the GTX560

    Am I missing something?

    The 650w version has 2 6+2 pin connectors and it should sustain almost every GPU I throw at it so I'd kill two birds with one stone. But it costs almost 20€ more and I'm on a budget.
    Anyway I don't think I'd push myself over a GTX660ti. The 550w can handle it? I'd really don't want to buy an overkill PSU with plenty of watts I'll never use.
  8. o ok

    it has a 6 and 6+2 so two 6 pins are available.

    edit: nevermind OP saw that . . nothing to see here move along . . .

    The xfx pro550 does have a 6+2 and 6 pin. It will be more than enough for a gtx 660ti.
  11. Ok then this settles it. 550w!
