dual opteron 12 drive good PSU wanted?

just putting together a new workstation with dual 280's, Tyan k8WE, 12x SATA2 drives (10 in raid 5) 1 x Radeon x1800 card and 1 x Raid controller card, all in a Lian Li v2100B case (which has 12 internal hard drive bays) BUT... it seems this case can't take the PC P&C 850 watt supply which would have been my first choice - despite being an eATX case, that PSU is just too long.

sooo - I need another top quality PSU - got any recommendations?
-something like 600W pretty quiet and a lot of good cables

it must be able to run 12 hard drives (or up to 14) and 2 PCI-express slots (1 video card, 1 Raid card)
 
I'm not even close to what you are doing but tasburrfoot7836 has a monster Enermax with two PSUs to meet his needs, with quiet stability. He will post later i'm sure. Zepper may have something to offer and his advice will be sound. There maybe others that will post,IDK.

It's only .44" shorter but take a look at the SSL-9850P at www.zippy.com. click on more details for the full spec and go down the page because at the bottom are the real deal Amperage ratings that matter. Like overload at cold boot. On the right of the units page will be a red box, there you will find for all the world to see the independent testing certs. I have not seen one other PSU company openly post their certs. Zippy is one of the last to make PSUs in Taiwan, they are top tier.

You might have a look at what I-Star has to offer.

That's about as good as i got.

thanks, that Zippy looks suspiciously like the PC P&C 850 anyways. I wonder if thats where they get it made, with a few mods?

Is there any chance of modding the case to accept two PSUs? Just wondering, as it might be cheaper than getting one massive PSU. And haing two will let you dedicate one to the hard drive and video card, without sacrificing power to the mobo & duallies...
 
Honestly, I can't hear them over the other fans, so they aren't especially loud. So I couldn't tell you how they would be on a normal machine. But I've listened right up next to them, and I can't tell any discernable noise from them.

Sorry Zippy and Emacs are not associated with PCP&C in anyway!!

BTW--just my opinion but Emacs are junk!!
Just take a look inside one....your paying for empty space!!

 
JEDI....You crossed the line.. 😀

Who supplies PCP&C with most of their high quality componets?
PCP&C just installs huge heatsinks, load fans, paints'em black, adds sleeving
then doubles the price :laugh:

The SSL-9850P maintains it's full rated out-put at 50C.

Please! Some of us have done a little research, just as you have.

I just got off the phone with George at BTOS, one of the main Zippy/Emacs Reps. here in the SW. His primary language is Chinese and he is reluctant to talk about what goes on in Taiwan at the Zippy factory but he did conferm what has been said, that Zippy is the ODM for PCP&C.

Example: Is an AMG any less a M.Benz. No! It just cost more for all the bells and whistles 😀

ok thanks for your help, it looks like I will cancel my PC P& C order for an 850 and go for another PSU.
what's the word on Silverstone Zeus 650W ST65ZF?
or, ? - I need a dual opteron ready PSU (EPS in other words) with LOTS of 12v rails/leads... and two PCI-express connetors

the raid controller has staggered spin up, so that should help things a lot, and my video card wont be doing a lot of intensive work, so I might be ok with a well designed 550W one.

its either that or keep the 850w PSU and buy a case to fit it - which seems to be the wrong way around...
 
For this sort of use I'd reccomend one of these and two of these

I don't reccomending using a K8WE in a Lian-li anyway. You want a steel chassis for server/workstation usage. I have a K8WE and the associated peripherals and had it in the very case you're considering but I couldn't tolerate the noise. Aluminum doesn't do a damn thing to dampen sound. And who cares if your server is lightweight or not. Its not like you're going to be moving it all the time and they're on casters anyway.

I have my workstation in a Enlight EN-8950B00 (like this) and I'm using a Seasonic S12-600 for the system and a modified Meanwell for the RAID subsystem and GPU dedicated power.
 
hmm, thanks for the tips, was aware and going to order a supermicro 5 into 3 hot swap bay anyways, but feel I should point out that the Lian-Li has built in sound deadening, so it is (apparently) reasonably quiet, though you obviously disagree.
which PSU were you using with that combo then?

if I do another PSU:
Seasonic S12 600W?
Enermax liberty 620W?
Silverstone Zeus 650W?

can't find good Zippy's easily for sale and suspect they are the same as PC p&c 850 anyways,

 
ok, after reading through Toms stress test, I realised there's very few PSU's that can handle this amount of drives, (and allow spare capacity for future) either in power rails or connectors, so I'm going to try and stick with that 850PSU in the end.
- I talked to the FrozenCPU guys (helpful) and they are doing a special case mod for me that should allow the 850 to fit and retain 11 or 12 bays, in their correct position. costing me $120 more than the case would otherwise cost from a cheapo store, but I"ll be all set.

hopefully end of story unless something untowards occurs.
thanks all for help.


 
Zippy is easily obtainable (Just go by manufacturer at newegg) and are VERY high quality. PC Power & Cooling modifies Zippy components for thier own use quite a bit. I know because my Uncle worked at the FedEx center in Carlsbad and happened to bitch about one particularly massive (17 pallets) order from Zippy to PCP&C. Thier forklift was broke down so they took damn near three hours to unload with a manual forklift. Though I should point out the 700W Zippy is no different than the 500W when it comes to the 12v rail. I'd actually take a look at this

What RAID card are you getting? I'm holding out for LSIs new PCI-e SAS offering. I can't wait to see how well it will perform with a RAID0 of two SATA SSDs, one 15KRPM SAS, and a RAID5/6 of Western Digital WD4000YRs.

 
Decent Zippy prices...BTOS, talk to George

For work station/server PSUs look under power management...axiontech.com/...Stumbled on to these folks while Zippy shopping. Great price on the PSM-6550P @ $210. The other pricing may not be good but this Zippy sure is. Too light weight for your needs peegee and the fan has no thermal control.

okay I stand corrected.....
I just talked again with my friend at PCP&C and told him what Galvanized said as well as others about the PCP&C product....

He said the information that I required was proprietary information and as such he could not directly affirm what galvanized said....

But now heres is the interesting part...

He pointed out that what galvanized said is true industry wide...notice the choice of
words....

Also he pointed out that there is NOT one company in the industry to his knowledge that does not deal with other PSU manufacturers for parts or vice a versa...

He also stated its common knowledge thats some companies will actually buy the whole PSU from another company and then add the bling...such as a new housing that is anodized or highly shined or a new LED fan...etc......

Then there are companies that basically take a solid well built product and make it better a lot better to the point where you truly have no idea who made the PSU...

But as such my friend only spoke in generalities........

So I stand corrected!!!

But my friends last point was very right on the money......get it money=PCP&C..lol

Anyways he said.....in the end what counts is that you have a quality product that meets all of your powerdemands!!

I have always said Zippy was in my top 3 PSU`s......
Enermax on the other hand..well.....

With that said.....whats has been said on this thread still does not change the fact that PCP&C still comnes out on top of the pack!!

With Zippy and Seasonic very close 2nd!!
