PSU died on me... What to buy?? - Page 2

If in doubt you can add your specs into the PSU Calculator here to get a very reasonable estimate of real world power draw.

If you do get the XFX PSU, stay away from the Core series, my friend bought 2 of them and both of them have insane fan rattle. There's a warranty voiding fix for this, but you can avoid this altogether by picking up a different model.
Calculators are extremely poor.
And having an "Overkill" PSU lowers the efficiency drastically.

Not necessarily. If a power supply has the 80+ rating, it's output will be most efficient at the 50% power level so taking my rig as an example, I draw 380 (AC watts) at load on an OC'd i7 (3.4ghz) plus an SLI of GTX260'S so my rig draws approx. 304w from my Antec TP New 750..... about 40% of it's rated capacity, so it's running cooler and more efficiently

Besides, I would rather have a PSU running at 40% of it's rated capacity than one that is running fully loaded, hotter and not as efficient as the 50% level, but that's just me....

The whole efficiency thing is blown completely out of proportion and highly misunderstood.
Firstly, a difference of 1-2% in efficiency between 50% and 80% load amounts to nothing on your power bill at the end of the month.
But if you're concerned about efficiency, here's a question for you -- if you're at 40% of your PSU's maximum rated load when your computer is under load, then what's the load percentage when your computer is "idle", i.e. when you're just using regular Windows, browsing the web, and all that? Probably <20%. Efficiency typically plummets under 20% loads, often dipping under 80%.
That's why it's best to get a PSU in line with your component's needs, so that you're in the efficiency sweet spot when idle.

Haven't created a for sale thread yet. Selling it as soon as I clean it up - just removed it from rig last night, this is a brand new unit that was received from an RMA of an older psu that had a bad fan they upgraded me and sent me back a brand new one (so this particular PSU has only been running since September 2010) and only getting rid of it since I am going fully modular with all of my rigs little by little.

yep $105 shipped but with it going across border there are some minor caveats I would mention to you privately.

PM me if interested.
