Unexpected bonus raising PSU concerns

I put together my first build recently, planning to buy a GPU after the main box was up and running. I was aiming for a AMD 6950 (MSI Twin Frozr3 OC specifically) but was having no luck finding them in stock for reasonable money. After being frustrated a few too many times, I decided to take the plunge on a 7850 instead and preordered a MSI Twin Frozr3 edition.

It came yesterday, I was reading the box and wondering why the back was covered with info for the 7870 instead of info for the card I bought. It was at this point I made the massively pleasant discovery that I seem to have been sent a 7870 by mistake.

Putting aside the moral question as to whether I contact the retailer to tell them about their mistake, now I come down to my slight dilemma. I understand that 7870 is supposed to need a 500w psu minimum (according to AMD and MSI) but a few specs I've read within various reviews and benchmark tests say the actual minimum should be a 550 watt psu which is exactly what I've got (corsair TX550 Modular) and I'm a little uncomfortable about having a PSU that's the bare minimum required.

Current system:
i5 2500k at stock speeds,
500gb HD,
optical drive
8gb Corsair vengeance ram
4 12volt case fans (with plans to add a 5th 140mm fan for my intake once I get an extension cable)
Near future upgrades may include a SSD and maybe a slightly quieter aftermarket CPU cooler.
I'm not contemplating overclocking just yet and when I do, I would obviously upgrade the psu. The question is whether I do so now.

Am I being daft worrying about my 550w PSU being inadequate or should I consider getting a higher wattage psu now rather than later?

Hello,

First off, nice! Second off, what Power supply do you have? If it's a good one - you should be fine. If it's a cheap brand like rocketfish you might have issues.

Edit: My bad. I missed your PSU part. I looked it up - and you should be good to go! Don't try and overclock yet though ,as it may push your PSU to it's limits.

It was very nice. I opened the box to check (as the 7850 is kinda short and stubby compared to the 7870) and I'm not ashamed to admit I did a little dance.

The PSU is a corsair. It's a TX550 Modular.

I would keep the "free" upgrade if I were you. Yea it's not nice to keep something that really shouldn't be yours, however on the flip side your dealing with (probably) a large company.

You should be able to rock out with that GPU and PSU no problem!

A person that compromises their values have no values. Saying this, are you a moral person? If so, call the company and they'll probably tell you to keep it and you'll feel better.

Another thing to note, if something happens you won't have a warranty because I'm sure the invoice is for a 7850.

Flip a coin. You could end up getting some minimum wage employee fired for shipping a $100 extra card.

If for some reason you do return it, make sure to hide a note in the manual saying to post here. :)

He should be fired, he can't read. :lol:
