Ok everyone, I broke down and got an EVGA Supernova 750 G2. It was a little pricier than I would have liked... Ok, a *lot* pricier than I would have liked! But, she works great so far and has a 10-year warranty Also has a dual ball-bearing fan, which is nice, because I hate busting open power supplies just to change the blinkin' fan after it seizes.

On Eco mode, the fan doesn't run at all until I put a whopping load on the card and CPU

Turns out the CPU cache will actually overclock slightly better with this one than the cheap old Rocketfish. So, I can run 4.5 GHz on both cores & cache without bumping up the voltage. Nice!

Finally, I hooked up an AC ammeter to the input, and it uses about 4.2A of current from the wall outlet with the card and CPU under AIDA and Furmark stress tests... about 480W. Looks to me like the 750W was overkill, and I spent more dough than I had to.

Oh well, it's a nice PSU, and I can flog my graphics card as hard as possible now

Thanks everyone,
Peace and happy warfare

I would rather spend more than I had to than regret not spending enough. It is only money and you can always eat ramen noodles for the next month.

Sage advice indeed.

@ AD sounds about perfect plenty of overhead available and about 60% utilisation.

EVGA Supernova G2 750w max output.
It's 504w (4.2A X120v) at the input of the PSU, 452w at the output (90% efficiency). The PSU dissipates/burns 52w. Your at 60% of the max load of the PSU
Maybe, forget the useless ECO mode (notably on summer time) to keep your PSU components always fresh/cool.

Looks okay in pixels

I have had no issue with my 850W version.

I wouldn't call the Eco mode useless. That fan is barely needed
It only kicks in when both CPU and GPU are having the living boogers flogged out of them. All other times, including most gaming, it doesn't run at all.


As far as I'm concerned it's just another case fan

I yet have to hear my PSU fan spinning.

Other than extreme OC beyond 600w it never even bothers spinning up, AS LONG as the temps stay below 45°C, which they usually do even during hot summer days ( I sit in a rather cold cellar room )
