great power supplies?

from Stardock Forums

I'm still getting my computer together, the only part left is to buy the processor, but I've noticed something unnerving, my enermax 600v noise taker that I bought, has been removed from zip zoom and new egg  for reasons I don't know.  And there has been reports about how unreliable it is.


I need a power supply that is 600v or better, SLI, and isn't super loud. Does anyone have any suggestions?

No recommendations for a 600 Watt, but here is a good Antec 550 Watt (SLI Ready, and a single 120 mm fan for minimal noise) http://www.antec.com/us/productDetails.php?ProdID=22552

I swear by Antec power supplies, and the one here has user controllable outputs.

They also make two other 550 Watt models in the same TruePower 2.0 series, one with standard dual fans, and the other with the single 120 mm fan and no user controls for the individual dedicated outputs.

They're not on those sites anymore because they stopped making them. The 600w flavor now comes as V2.2. The only difference between it and yours is 22A on the dual 12v rails versus 18A on yours. The 600w V2.0 you have is fine.

Here's the one I bought recently:

http://www.newegg.com/product/product.asp?item=N82E16817194004

It has seperate power connectors for PCI/Ex video cards and all of the cabling is modular. Only use the cables you need for the devices in your computer. I've had the PWS for a few months now and have had no problems whatsoever.

I had a brand new Enermax 480w for a new system that I put together 2 months ago and it was nothing but problems. My computer kept rebooting randomly and it drove me nuts. I thought it was the motherboard at first, so I replaced it. After that, my computer wouldn't even boot up, it just turned off. I ran out and bought an Antec 550w and it runs like a charm! The computer doesn't reboot and runs quiet. I picked out a 550w because that was the highest watt available at that store and everything else was closed. 550w is plenty of power for my system, but I do know that Antec makes 600+w. After my experience, I would NEVER buy another Enermax! Antec all the way!!

Im not as "tech savvy" as Yrag and Corky about these things...
But I can say from personal experience that the *Aspire* PSU that I have been using has operated very smoothly without problems...
They do make a 600w model...

Heres the link just in case your interested in researching them...Link

If it works, use it.

Sounds like you got a bad unit. It happens, and problems like that aren't caused by bad design or a bad product but it was just bad luck. I've personally never had a single problem with and PSU I've ever bought, so I've been lucky.

I'm fond of my PC Power & Cooling 510 SLI unit.

About the antec 550 true power 2, does that work with amd 64 x2 processors? Also my case is also from antec says it uses the atx12v so would that limit my choice to the truepower 2 antec? Also I didn't see any 600+w antec power supplies.

I never had a PC Power unit go bad, good power supply, I understand that they have a 1Kw now.

Cooler Master 550W Real Power PSU

That's the critter I got once my no-name 400watt PSU turned up its toes.

Works just fine, too...

It's the CoolerMaster 550.

 PSU would NOT shutdown from an over-current situation and resulted in damage. 12V rails loaded each to ~18A, voltages were within 4% of tolerance. Verified peak load rating of 530W.

 Excellent efficiency, 85% under typical load! Also has active PFC! ould not get PSU to shutdown from current or temp overload. Voltage levels would just continue to drop and current would never go higher than about 720W (AC, so figure about 560W DC).
