Hello I am going to buy a Sapphire Radeon RX40 4 gig GPU today.

Years ago I bought a questionable psu the ocz modxstream pro 700w

It has been running fine for me but I really have never put any sort of load on it like

a fast gpu l;ike the Radeon RX 480 would.

This psu on newegg caught my eye. http://www.newegg.com/Product/Product.aspx?Item=N82E16817151118&ignorebbr=1

Would this be a decent psu. 64.99 plus 15.00 rebate

Or would I need more power like this one.

A few dollars less with a 20.00 dollars rebate.. It is not modular though.

The modxstream was a mediocre PSU back in its day. Wasn't good, but wasn't bad either. It would handle its full rated output, but given its age, it probably cannot handle full output anymore.

What is your system components? If it is an Intel mainstream CPU with the RX480, you're looking at a maximum load in the neighborhood of 400-500 watts. The CX PSU is a significant step down in terms of quality from the Seasonic G-series.

Other current good options are the EVGA 650 G2, 650 GS, Corsair RM550, RM650x, and RM550x. Based on today's pricing, I would say the best value is the EVGA 650 G2.
 
Well my system is a Phenom II X4 940 6 gigs ram Gigabyte GA-MA790GP-UD4H motherboard. DVD drive 2 hard drives. The seassonic yesterday had an additional 5 dollar promotion code which brought price down to 59.00 plus the 15.00 rebate.

I pulled the trigger and bought the psu with the RX480 gpu.

Thanks
 
Tsumi is correct about the actual power needs of your system. If you don't overclock, then a quality-550watt PSU will suffice.
Also, all these units mentioned above, along with Seasonic G650, are all of them solid midrange/mainstream-category PSUs. Which one you'll choose depends on which one you will find cheaper, and it's a matter of personal taste as well.
My personal ranking would be: RMx > Seasonic G-series > EVGA G2-series > EVGA GS-series. (* i have used G-650 in the past, along with G2-750 & G2-850, and personally , i was more satisfied with the Seasonic unit, but this is just my subjective opinion as a customer ;))
 
Funny that these are now considered mid-range/mainstream. 2 to 3 years ago they would be considered high end.

I think it's more like 7-8 years ago but yeah, now the "high end" are the kilowatt+ monsters that virtually no one has a real need for. So much e-peen.

Wattage rating is not an indication of quality or high end/low end. Ripple suppression, transient spikes, voltage regulation, and choice of components are what determine quality.
