ePower PumaII

[Firestrider]

Is this any good? I'm looking for a good power supply at around 450W. The rails on this is: +3.3V@26A, +5V@45A, +12V@28A, [email protected], -12V@1A, [email protected]. My current is 420W with these rails: +3.3V@26A, +5V@32A, +12V@13A, [email protected], [email protected], +5VSB@2A.

I wouldn't trust a power supply that is that cheap. my MINIUMUM is ~$80. Look for something by Fortron or FSP or Sparkle. THey tend to be on the more inexspensive end of the high quality PSUs

What are you looking to use it in, this may cut it http://www.newegg.com/Product/Product.asp?Item=N82E16817104935

well, everything in my signature minus the 9600xt and plus a 6800gs and a 120mm led fan. I plan on overclocking all of this once I get ample cooling

 

[Firestrider]

I don't get the reasoning behind the dual rails; is the 12v1 for the processor and the 12v2 for the video card or something? How much current should be running through each? My motherboard has a 20-pin power connection, but that PSU says it has a 24-pin connector, is that okay?

12v2 is processor. 12v1 is for everything else.

Most PSU's will be a 20+4, where the extra 4 pins are detachable. The Epower is a 20+4.

The EPower is a Topower rebadge. That looks like the Topower P4 design. Not bad but not the best in terms of cross loading. About the same as OCZ Modstream quality.

It shouldn't have any issues with your current system.

Thanks for the reply. What about the FSP Group (Fortron Source) FSP400-60THN-R 400W, would that be a better choice, even though it has 50 less watts and is $20 more?

 

[Know Nuttin]

The Fortron has better build quality. I owned that exact same unit before, and was very satisfied with it. It powered my Prescott pretty well and would work with your current config. I wouldn't use to power much more though, especially a Prescott overclocked, it won't handle it. In that case, I'd recommend the EPower instead.

 

[Firestrider]

Well I have a northwood, would it handle it overclocked, or should I get the 500W version?

 

[Know Nuttin]

It should handle your Northwood no problem but it will be limiting if you decide to upgrade to a newer P4. If you're waiting for the next gen Intel that should be lower on power consumption, it may work just fine for that.

What is your budget for a PSU?

 

[Firestrider]

I don't plan on upgrading my cpu anytime soon, I want to try to the get the most out of my northwood first. The top of my budget for a psu is probably this:

[Know Nuttin]

You could settle for the AX450-PN if you want to save a bit of money. It will power your rig fine.

It's not so much about wattage all the time but how the output is distributed. For example, if you had a system that was +12v heavy on the requirement but only 140w available on +12v, even if the unit was a 1000w, it would be insufficient.
