PSU and Mobo Questions

I'd get this: http://www.newegg.com/Product/Product.aspx?Item=N82E16817182133

I've got it. Absolutely no problems! The 12v connectors are red but I've replaced most of them. Wires are a bit stiff but awesome power delivery. I've got a MAX oc'ed 580 with a 4.5Ghz 2500k and it handles it without any problems. 12v is around 12.20V idle and around 11.9V load.
Can't beat it, modular and a great price!

I would say just go with the G45, unless you're planning to try for an aggressive overclock (over 4.5ghz), which is hard to do on Ivy Bridge anyway.

Also, assuming your primary purpose is gaming, you might as well get an i5-3570k instead of an i7. The threads are really only used for workstation purposes, or for producing a stream. & the money could also be shifted right into getting, say, a 7870 instead of a 7850. But if you know what you need the extra threads for, no problems.

As for PSU advice, the Antec would be fine. There might be a better choice, but I can't really help more unless you let us know where you're buying your parts. Hardwareversand.de? a danish site? Generally you should be able to at least link a price list or something.

But you look pretty set.

Corsair makes good power supplies. I have a 650 watt one from that line and it works perfectly.

I am running a GTX 480 off my TX 650 V2, so I doubt that you would need more than a 650 watt for a single card. You should know that the the power supply has only two PCIe connectors, which will be a problem if you try to do crossfire.

Here's a chart of the 7850's power consumption:

Well for these sorts of questions I tend to turn to Phaedrus' handy dandy PSUCalc program found in the stickies of this website's power supply forum. An ivy bridge CPU & a single gpu aren't going to ever need more than 450w of power (from a quality, not crap, supply). But I assume you're budgeting for potential Crossfire/SLI. It brings up a total recommended 640w for an ivy bridge i5 & 2 7850s... and that's with the i5 heavily overclocked & the 7850s both overclocked and significantly overvolted... plus some extra safety room. That's higher than 620... but the Antec is a quality unit and is actually on the recommended list for the configuration you described in Phaedrus' PSUCalc... so the Antec is fine.

The PSU I'd probably go with as being a touch better than the lower-priced corsairs AND cheaper than them is the XFX core 650w at 602 kroner - not a bad price at all figuring taxes in:

But the above XFX is not modular. The XFX xxx 650w is modular -but it's 90ish kroner more and not currently in stock. (or 150 kroner more at komplett). The Antec high current gamer 620 looks to be the cheapest acceptable modular PSU at 650 kroner, and it is in stock:

If you want flashy LED-ness, you could also spring for the Super Flower Atlas 680w, a modular PSU of good quality that I believe has an led fan and glowing modular plugs (755 kroner):

Edit: looking at above, you already see my recommendations on PSU. On graphics cards, I'd stick with the sapphire - they're supposed to have some of the quietest coolers for the 7000 series despite their low price. Nice combination.
