@Phaedrus2129

I totally agree. My time here on OCN has taught me a lot about PSU's (especially from you and Tater Tot) and now that I'm knowledgeable in that department it saddens me when people recommend 750-850w for single card solutions. Granted I have an 850w PSU and a single card atm. I'm actually planning on a grabbing another 580/and or 590 so It will actually be of use to me. Also, it was the only gold serious SeaSonic model in-stock at the time and I really wanted to try one out as I had always gone with corsair in the past. Thanks Phaedrus2129 and Tater Tot, keep up the good work thumb.gif.

after all... this is OCN and we do it big.

EDIT: I don't get why you don't mention quality???

"then recommending a 650W or more is wasting their money."

My 700 watt StealthxStream could not handle my 6950 + 1090t overclocked...

FYI
Your unit was faulty then.
My Superflower 600w can handle a 1090 @ 4.2ghz, watercooled. a gtx 570 + 8800gt as physx. problem? none!

Thats plain wrong. This is power consumption AT THE WALL with GTX480 SLI + Nehalem i7: Furmark + Superpi:

---

i7 920 @ 4.2ghz + 2 x GTX470 @ 750mhz core, running JC2.

i7 920 @ 4.2ghz + 2 x HD5870 @ 950mhz core, running Crysis.

All this power consumptions are recorded at the wall and power supplies are rated to give the power they announce to the computer. So, you can see how there is a lot of crap ongoing about psu discussions. 560W at the wall = power supply providing less than 500W to the computer. So, a power supply rated at 650W could suffice in all those situations (although for GTX480 sli it would be too much if you overclock).

Guys...Phaedrus has a point. It is better to be informed about how much power your computer is actually using. Being ignorant and buying a 850 W PSU just to run GTX 460 SLI is foolish.

Granted, my 750 W PSU is overkill for my current rig although I did run CF/SLI with 8 hard drives before.

Fair enough, I won't trust those sites no more biggrin.gif I was considering SLI for a bit and got discouraged by multiple reviews stating that it would be tricky with OC on my PSU, which is one of the top PSU atm, quality-wise.

P.S. I need to buy one of those things to check my power consumption, out of curiosity.

Just so you know I'm not just talking out my ass here, I'm going to downgrade from my HCP-1200 ES to a Kingwin Lazer Platinum 550W. I know for a 100% fact that it will run my current system (Athena - Q9550 @3.4GHz + 2xHD4870) and my planned system (Minerva - FX8130P @?.??GHz + 2xHD6950/HD6970) without any issues.

Assuming someone buys my HCP-1200. One of the best performing PSUs ever built. It's an engineering sample, collectable, only a dozen of this marque exist and most of them are in a closet at Antec's Taipei office. Capable of running quad SLI GTX580s, never run above 550W load. $250 shipped CONUS if you want it.

Burning books is like burning bras; after the adrenaline rush of the symbolic moment wears off all you're left with is a pile of ashes and unsupported boobs.

What about when the price difference is negligible?
