Doesn't hurt to have more wattage. But like earthdog said unless you plan on SLI there is no need for 850. If its the cheapest deal you can get, then by all means get it.

Yeah no need for a super high psu unless you want to run multiple cards and drives. But pretty good deal for 850 corsair.

Mhm, to sum it up, more wattage is good, but if you never use it, it's just a waste of money.
You forget a third option. Just get the 850 and give it to me. I'm just saying... it's an option.
I would go with the 850 only if it's a screaming price. You don't need it, but a good price is a good price. I build the system I am posting this on that way. I sort of got it piece by piece when prices on a specific component was great. Right now I have an Antec 650W in it, and only really can use a 350W or maybe even a 400W. But the 650 Was around 50% off so I couldn't pass. It was like 5 bucks more than a 400W. If I make a rig with a high end GPU I can now throw that in there instead.

Nothing wrong with overkill PSUs if they're good quality.
Although often they're not as efficient when really underloaded, all have an efficiency curve... some have a wiggly line when comparing load to efficiency.

I agree i rather have a quality 400watt PSU then a 1000watt generic bestec dynex whatever you call it.

Overkill PSUs can be useful when you have dirty unstable power, the extra capacitance keeps power flowing even when interrupted for an instant.
The money saved on a proper sized PSU vs. an overkill PSU could be applied to a quality UPS which would help more with "dirt power" IMO. I can't believe anyone uses a PC these days without a UPS.

Dirty power lol have not heard that one before.
I havent either.. I dont know too much about this particular subject, but what I do know is dirty power, to me, is high ripple and noise in the line.
Im also not sure why a larger PSU would protect against line sags, seeing as how its not 'charged' and hold say 700W capacity when its only using 300W. BUt that could be my lack of knowledge. I dont know...

Soo true, UPSs are extremely useful, especially for those who work on their computer... also useful since sometimes they'll get cooked instead of your PC if there's a surge.
I've observed that overkill PSUs with active PFC don't cut out as easily when the lights flicker.
I don't know PSUs really well(I've made some crude ones), but the main caps appear to be pretty much a straight path to the mains with all I've seen so they'd always be fully charged, although their charge would be lower with greater load in between the mains' wave.
