1250w Seasonic Psu worth it?

I'm sure it would.

As long as it isn't a junk unit. I don't think Seasonic makes junk.


From what i've heard, Seasonics are some of the better/best PSU out there.

I was left in the same position. I got the evga 1000 gold. It's very nice and has a longer warranty. Issue I have with it is the fan DOES NOT TURN OFF. Honestly I should have just dropped the extra $50 for that alone.

So if you dont mind a little fan noise I say get the EVGA but if you want silence...do yourself a favor and drop the extra $50....in the long run that's just gas to go to town and back a few days anyways.

An 850 Watt can power triple 770. (not sure on amd side though.

Oh damn, Maybe ill grab the X850 instead for $160 instead if i cant run it with this PSU.
Gotta wait a bit anyway, XFX is sending me a replacement cooler because the fans on this one are dead.

1250 is ridiculous overkill

Side note, I've seen 580 sli on a 750 Watt, so you might be able to get away with what you have

Nah, something like a 750w - 850w Seasonic will do just fine.


For the what $50 difference, i would rather leave room for later should i want to grab something like a pair of 290x/780/880's


You're greatly overestimating the power draws of dual cards. ^_^


So, say a 850W PSU could power a pair of 290x/780s?


It can, but it'll not be efficient cause it'll draw more power from the wall due to conversion. If I recall correctly, PSU's are the most efficient if the load is 60-70% of the rated.

So an 850 watt psu would be ideal for around 595 watts, gives the PSU ample room to convert to pull the power from the wall, the power delivery is cleaner and the PSU will last longer. Granted, you can run a psu @ 100% but it'll shorten it's life

I'd go with at least a thousand or more. You'll save the money on your electric bill after a year

or you can push the PSU and if it goes pop, the rest of your system could go = bye bye

So long story short, Dont bother with 1250W unless i do something like Quadfire 290x?

For a gold or platinum power supply optimal power draw is 80-90 percent, that's when 90+% of out the wall is converted to what the computer can use.

Yes.

But never do quad GPU anyways. The performance scaling is terrible.

Two graphics cards will scale roughly 90 - 100% depending on game engine and drivers. (Roughly double FPS)

The percentage goes down as you add more cards, but you're always paying full price for the cards. Diminishing returns.
