Links didn't work for me. Here's our PSU thinking: http://www.tomshardware.com/forum/id-2547993/psu-tier-list.html

You GPU has 250W TDP, and your system will not use over 125Wv even overclocked to the max. 600 - 620W is plenty, provided you have about 500W on the 12 volt rail (which most modern PSUs in this range will have)

Would never buy either one for what you want.

Both of these are far better and cheaper.

This one too http://www.newegg.com/Product/Product.aspx?Item=N82E16817207034&cm_re=xfx_psu-_-17-207-034-_-Product

I accidently chose a answer lol sorry

 

[DonkeyOatie]

I unselected it for you.

How can we help you further?

 

[dash123]

I own both already I just want to know what would benefit me more

Well, between the HX and XStream, the HX is clearly the better of the two since the HX is a gold-certified unit which is guaranteed to work up to 50C from tier one on the PSU list while the XStream is only a bronze-certified unit that barely meets its specifications at 40C.

The HX is by far the better (Seasonic OEM, I think) Gold rating is good, decent capacitors is much better. I'd certainly use this PSU if someone gave it to me, it's just that I would not pay over $100 for it.

The PSU has only two PCI-e cables, so some GPU configurations may not work, and the fan can be loud.
