Has anyone heard this PSU in front of them before? Are they significantly louder than Seasonic S12s?

Frim what I understand the Zoppy`s are as noisy as the PC Power & Cooling 510`s before PC Power & Cooling went to a thermostatically controlled fan!

Good Luck!!

You need to remember both Zippy and PC Power & Cooling are considered to be industrial PSU`s!!

hmm... i see.. =/

should I take silence or stability?

I'm not saying the S12s are unstable or anything, but I've heard zippys are rock solid...

What wattage are you seeking? Link to Zippy model, please.
Buy.com has the Corsair HX520 for $88 at Google check out. It's built by Seasonic
and is a well reviewed and semi-modular.

Well this is for a system in August 2007, just contemplating case and PSU at this point. I doubt they'll change.

CPU will be dual or quadcore probably. Whatever K8L comes with. I was thinking about doing a SFF case =P but I might just end up doing the tower.

Either way, the case can take ATX PSUs.

I was thinking about this Zippy, the HP2-6500PE

But if this is a screaming PSU... I might have to step back to the S12 or something.

Oh btw, are PCP&C PSUs any good? I know they have a painfully high price, but it's close to that of the Zippy.

Do you suggest the Corsair because of the price Galvanized? I'm in Canada, so i can't get it at that price anyways =P

The Corsair is a very good unit and that price is fair.
The Zippy you linked will be about as loud as a Fortron with an 80mm fan.
Not bad below 200W but noticable at 300W or higher.
Do some reading at http://www.jonnyguru.com/ > forums. There are several Canadian members.
Like all hardware there wil be some rapid changes in the next few months on the PSU front.
Many new units will be coming out and prices will be falling.

For quiet & good at 500W, consider the Silverstone 500W Element. It's not as good as Seasonic but is cheaper.

Ahh... hmm I'm loving the lack of ripple on the Zippy... Oh well... Loud won't do any good.

I think I'll be going with a low power, cool and quiet system. With the V300 =D always wanted to own a Lian-li.

Thanks for the advice Galvanized, I'll be sure to keep reading about the PSUs in the coming months.

If I'm not mistaken Zippy PSUs are Tier 1 and Seasonic S12s are Tier 2. Not that a Tier 2 wont do the job properly. Server grade PSUs are typically louder than mainstream PSUs from what I hear. However, you dont need a server grade PSU for a gaming system.

I've come across the terms Tier 1 and 2 and such before. However, I don't know what they mean. Can anyone enlighten me please?

Also, the system won't be for gaming. I just want it to last 4 or 5 years. Until my brother finishes university. Probably only for office/web browsing. I wouldn't be surprised if he put some CAD programs onto it though. He's going for architecture.

No way jose! :p Some of the tier1, server grade PSUs have very good thermal fan control.
Like the Silverstone Zeus units, provided by Etasis :)

The recent OCZ units go out of ripple spec at full load, that is NOT a good sign ;)

Many Zippys have a 24/7 full speed fan as standard equipment that can get irritating, but that wouldn't make a lot of diff in a computer room or closet. You can get a temp controlled fan as an option or just buy a fan w/ a built-in thermistor and put it in yourself. Or you could run a fan extension from the standard fan to a fan controller. No big whoop...

Or you can do what I did to one of my Zippys that came with the buzz saw - Outside the Box .

IIRC doesn't PCP&C get at least some of their PSU from Zippy. Irregardless, both are borderline industrial class power supplies. I would only recommend getting a Zippy if you plan on running a high end Peltier cooling setup. PCP&C and Seasonic will be fine for everything else (Obviously with PCP&C being a step above Seasonic)

OCZ's PSU's are nice, but they are all based on a heavily modified ToPower unit. A far cry from what Zippy and PCP&C have.

The closest you are going to get to that quality is Seasonic. Their PSU's have arguably the best fan controller out there, and to cap it all off they make some of the highest quality consumer grade power supplies. (I love my Seasonic 500 Watt S12).

Zippy builds for no one but Zippy.
PCP&C Turbo series are built by Win-tact, the Silencers by Seasonic.
Mushkin is built by Topower and are to be avoided.
OCZ is now OEMed by FSP, they are based on the Epsilon and go out of ATX ripple spec near full load.

Yes, the S12, M12, Corsair and Silencers are all good but the NeoHE(OEMed by Seasonic) units are not near as good as any of the former. :p

I have the Zippy PSL6701P (60A) in several dual opteron builds. It is loud all the time..

But you really can't hear it over the 10 - 15k Fuj scsi drives.. Imagine a hovercraft right next to you..

I'm now using PC Power & Cooling's 750w psu.. (60A) .. for $200

Regards,
Jose

Yes...OK... I have a HP2-6400P and a HG2-6460P in use, they are no louder than my old Fortron 400W with "Noise Killer Fan Control."
My HG was modded as pictured/linked by Zepper.
You can keep the bee hive of SCSI drives :p

hmm... I just realized that the case I'll be using doesn't work well with 120mm PSU fans =o.

I'm going to be using the silverstone SG01evo. Unfortunately, the CPU cooler is directly below the PSU. Both fans will be competing for air if I use a PSU /w a 120mm fan. I really like the corsair because it's modular (It's going to be cramped working in that =/) and it's relatively quiet.

Do you guys think this will be an issue? Or should I just go with it anyways? It's not going to overclock anything, and chances are it'll be a very low power system. I'm planning on using the AMD EE cpus if they come out for K8L.

=_=' Don't people make reliable, modular, quiet PSUs anymore? I found the SS zeus, but the wires are going to be a huge pain to work with.

What does tier 1,2,3 mean anyways?

Link of said case with decent pics.
I'll post in the AM.
Some of the Silverstone Zeus PSUs are quiet and use an 80mm fan.

Thanks for all your help Galvanized

Here's pics of the case.

pic1
pic2
pic3
pic4
pic5

As you can see in pic5, the PSU and the CPU fan will be competing for air if it's a 120mm PSU fan.

How hard is it to mod a CPU HSF to spin the other direction, and how much cooling performance would I lose if I did that?

Postage stamp sized pics :p Link to case's home page, please ;) I did take a quick look at Silverstone and Lian Li and didn't see a similare case. It is aluminum?

The stock CPU cooler will not starve for air with a 120 PSU fan facing it. Small fans will pull more mm of h2o because of thier higher fan rpm...Generally.
If you used a HS like a SI-120, you would want atleast 2" between the PSU and HS's fan.
Those side fans are vented through the side cover, are they not? So you'll have plenty of intake air.

If you decide to get a PSU with an 80mm fan there are two things which will quiet them down.
1-On the wall behind the case tac up some thick carpet or soft cardboard eggcrate, like 18 eggs are packaged in...Works.
2-On the intake grill, next to where the harness exits, bond a 80mm fan that puts out 30cfm. This will cool down the secondary HS where the units thermal control generally is.

I used a Zalman 80x15 on my Zippy and feed it 5V but if I were to do it again, I'd get a Arctic Cooling 80x38 from Provantage.com. It's damn near silent at 28cfm. Don't use a straight bladed fan, use one with cupped blades because they will drive air through fins/grill work better.

ahh... I thought the pics would come up normal size... oh well. here's the link

The pics are primarily on page 4 and 5 of the review.

Yes, the case is aluminum.

I was thinking of changing the stock cooler to the Zalman CNPS7700, or the CNPS 8000. Not sure yet. There was also the silverstone NG06 cooler. It's a heatpipe cooler that's placed directly beside the PSU fan and uses that to cool the CPU. I'm doubtful of its cooling capabilities though.

I'd like to use a better cooler, but I only have 7.8cm clearance to the PSU.

The idea of a zippy psu is great =D but would I have problems dealing with cable length? The entire case itself is only 393mm deep 0.o

The depth of the PSU is 140mm, and the PSU can't be over 170mm -_-" It might be hard to fit the zippy with the 80x38mm fan on it aftewards. I'm looking at the cable lengths and they're hitting 600mm 0.o That's almost double the case depth =/. I'm starting to doubt the possibility of putting in a zippy =/

That case is ventilated very well. Here is the PSU recommended on page 6. http://www.silverstonetek.com/products-50ef-Plus-sc.htm The SC stands for short cables. But this PSU will not retro-fit to a standard ATX case.
Long cables can be warmed up with a hair dryer, then bundled up neatly with zip-ties. ;)

EDIT: For unrestricted performance fans must clear anything on the suction side by the thickness of the fan. So 78mm=3 inches, that's plenty to play with.

hmm... i never considered using a blowdryer before... thanks =D

btw, 78mm is the thickness including the heatsink 0.o

in my limited experience (3 weeks) the Seasonic M12-500 is reliable, quiet and most definitely modular.
