Hi all, I'm building a new PC for the first time and after several weeks of searching to see which components best suit me I have finally decided what to get. The first item I went to buy was the power supply, because it wasn't in stock - I asked a local shop if they had the XFX Pro Series Black Edition 750W (80 Plus Gold, full modular) and told me that they could get it within a week or two against a small deposit.
All's well so far...however, when I went to pick it up I noticed there was no 'Pro' labelling, although it did say it was 80 Plus Gold rated and it was also full modular. Moreover, the product code (P1-750B-BEFX) matched the one of the Pro Black, so I thought it may have been named differently for the EU market (I live in Europe). Nevertheless, when I got it home I did some searching around and found that in fact my PSU is from the new XTR series - tbh I didn't know the XTR range existed alongside the Pro series, or I probably would have said something in the shop.
Now, my question is this - the shop also has an XFX XXX 850W Silver edition for only a few euros more than the XTR, which seems to have a proven track record with several positive reviews - the XTR is as yet pretty much an unknown entity. I believe the XXX is also based on the Seasonic X-Series, while the XTR is based on the slightly inferior G-Series - is it worth going back to the shop, trying to complain that what I bought isn't exactly what I ordered and try to exchange the XTR for the XXX? The main reasons for doing so would be the higher wattage (although I don't really need it) and, mainly, the fact that I think it is slightly more high quality that the XTR. That said, the XXX has a lower efficiency rating, is quite older than the XTR, is not fully modular and I have heard that the Pro Series sometimes have a habit of making some pretty audible noises...so, what do you all think?
Thanks in advance for your replies.

If I'm honest, I'll probably only ever install one card, but someday I'd like to dabble with having a multi-GPU setup.
I guess the big question is this: will the fact that the XTR may be slightly inferior to the XXX make much of a difference in the real world? As I said, although an extra 100W would be nice, I don't really need them, but obviously as mentioned it's got a more proven track record than the XTR...
