Ok, apparently I put in some wrong settings.
I'm getting 363w recommended now.

179% overkill.

650/712 = 0.91

I'm still wondering if i can safely run my system like that.

I got the 2nd 470 sitting in its box on my desk mocking me

It did although manage several vantage runs just fine. I just dont know about leaving it there

You sure wish it would. The difference between lets say, 75% and 90% efficiency will save maybe 10 dollars a year. Give or take a few dollars.
Apparently you've never paid an electric bill.

Let's take a 300w average load.
Antec 550w Truepower 2.0 is ~73.5% efficient
Seasonic x750 is ~91% efficient

Therefore, a DC load of 300w would end up pulling from the wall:
Antec : ~409w
Seasonic : ~330w

About 79 watts of difference.
Electricity in virginia is about 10.5 cents per kWh.

Leaving the rig 24/7,
79w/hour / 1000 = 0.079 kWh * 24 = 1.896 kWh for a day.
*365 = 692.02 kWh * $0.105 = ~$72.66/year in savings.

Where the **** did you see 73% effiency? The Truepower New series is 85% at a 300w load and an average of 84% across all loads.

At a 300w load, which is the Seasonic X series prime load you get 91% and an average of 88% across all loads.

Assuming 100% load = 300w then of course the Seasonic is going to be more efficient but not nearly the difference your making it out to be.

So either your lying and skewing the numbers or are getting your numbers form a non-reputable source.

I dare you to question my sources.

@WTH: He's talking about the TruePower II series.

TruePower
TruePower II
TruePower Trio
TruePower Quatro
TruePower New

It's an extended brand. The TruePower I/II units were decent performers for the time but inefficient and had extremely high failure rates due to CWT using Fuhjyyu capacitors on the secondary.
