Powerstream 600W or Power & Cooling 510W?

RedDragonXXX · Jul 26, 2005

I'm in a market for a new PSU for my w/c setup and I got my chooice narowed down to these two, either Powerstream 600W or Power & Cooling 510W SLI.

Which one would you guys recommend?

Vulcan · Jul 26, 2005

Out of those two? The PCP&C. Main reason being that the OCZ has that stupid green led fan.

However... I'd also consider the Seasonic S12-600, Is noise a concern? The OCZ or the PCP&C are not anywhere near quiet while the Seasonic is near silent.

I have the OCZ, and I cannot hear it (wedged in my Sonata for now) over even the ATI Silencer. I guess YMMV on the OCZ, but I'd say the bang-for-the-buck going now is the mentioned Seasonic or the BlueStorm.

I like P&C because it has most punch in the 12V Rail and that's what I need, also Powerstream is good because it has adjustable rails.

They are both great PSU, but I can't make up my mind :shrug:

You shouldn't really need to adjust the rails in the first place.

I Choose PCP&C since it is a better PSU and is SLI Ready. (Meaning you won't need to buy any connectors to make it work)

You do when you have 8 12V fans running in your case and other components that draw power from it

In a power supply with good regulation the voltages should not drop even if you are heavily loading it.

That's why I want a new PSU and also keep in mind that I'm running an OC'ed system, so it takes a hit form that department as well.

how are you measuring thses rails?

MVC · Jul 26, 2005

Sorry, but... what exactly do you intend to run on it? The OCZ is an excellent PSU but the dual rails have been a problem for some who are really pushing their systems. Without more info I'd play it safe and say the PC P&C, but depending on your system the dual rails may actually be beneficial, so....

Hmmm...that is a pretty tough decision. Two great psu choices. My vote goes to PC&C.

Through BIOS, ITE Smart Guardian... soon with the multimeter. After I added four 12V Delta VHE's my 12V rail droped form 11.71 to 11.64.

Join us... come to the dark side of the for-- err power supply units.

I just switched, not a damn complaint except for a little extra noise. My motherboard 12v sensor is horribly off, but it doesn't falter, and that's what counts.

You know you want it.

Also, I have five 12v fans, three 120mm and two 92mm, as well as the fan in the psu. Take a look at my rig. I plan to move to 2x1GB sticks real soon as well as an X2, and I'm not worried at all about the load. I'm certain this beast can take on anything.

I love how they sleeved all the cable.

Before you go off and buy another PSU give me a chance to whip out my DMM and Digicam

This is all missing the point entirely. Vulcan was 100% correct when he said you should not have to adjust the rails. The dropping voltage with load is the symptom, not the problem. The problem is the supply is nearing its maximum output, and just cranking up the pots doesn't make the supply more powerful.

If you have a supply of adequate output with competent regulation, the only reason you would ever have to set the pots would be if they were set incorrectly to start with. If you have to crank the pots up to get the voltages reasonable with the load you are driving, you are overloading the supply.

wrong

lots of people like to run 3.3v rails high for vdimm mods

Just got a killer deal on a PCP&C 510 SLI and i must say it's awsome. I had used their non SLI version before this (on Pentiums) and the build quality is fantastic. It's easily the best PSU i've ever owned. If money is no object PCP&C. If you want a rock solid extremly capable PSU, don't even hesitate for a OCZ unit. Even the 520w should be more than sufficient to run any system today.

ShadowClock59 · Jul 27, 2005

Man, that PC&C is beautiful. I dont know what it is about that black paint, its just so.....black.....wow....i didnt know it could bee this seductive....NOO....stay down credit card!!!!!!!

edit

Anyone tried out PC&C's 800w monster yet?

Powerstream 600W or Power & Cooling 510W?
