psu for dual xeon..

[DizzySHK]

i have narrowed it down to enlight or enermax.
enlight is rated at 480w
enemax is at 400w(it says p2u, psu for 2u rack case?)

i have read good things about both companies but never owned them.
i would appreciate any advice. thanks in advance.

 

[OPUS1]

Sorry to be redundent but
One word PC Power & cooling 510
It can handle anything you throw at it. And a 5 year warranty to boot
I had an enermax and it is good, but this puppy will let you sleep at knight!

 

[Ice Czar]

so EPS12V?
those with dual or quad +12V rails?

why dont you link them

and post what other components it will be powering

 

[DizzySHK]

ok, these are the parts that i picked out for 2u server

that's all the component
thanks for the input

Recommended Tyan Supplies that are 2U complinat
(all these supplies are SSI compliant EPS12V)

Etasis EFAP-462
A+GPB ATP-U2ATX50L
Enermax EG651P-VD
(actual recommendation is EG651P-VE FM(24P) - 550W, EG465AX-VE(W) - 431W
EG465P-VE FM(24P) - 430W but arent 2U compliant)


Other Supplies Id consider (actually Id highly recommend over those above)
Zippy Emacs P2M-6550P
Zippy Emacs P2M-6600P
(Tyan does list a Zippy 1U the P1A-6300P,
but these are the latest rendition of the new pumped up EPS12V spec in 2U,
and would likely be my choice)


and if its a critical server environment the redundants
Zippy Emacs R2W series
but Id do a bit more research first on those

as a note, considering the number of drives, Id stay up in the 500 > 600 watt range
since they arent SCSI and dont have any delayed spinup options,
you could likely get buy with less, but Id definately stick with the later EPS12V spec
which has dual or even quad +12V rails, as the CPU, and the drives are all on that rail now

Another Mobo to look at:

It's pretty sweet-

And If you are interested, I have a PC Power and Cooling 510 XE/ EPS12V that I was intending for a dual Xeon machine but aborted in favor of a prescott machine. It's never been plugged into anything.

I am planning on a dual Xeon in the future so I was planning on keeping it on the shelf- but if you want to be a buyer we can talk.

great supply and would be my 1st choice (see sig )
and is a Tyan approved PSU, but it wouldnt fit that case

as a matter of fact the first thing I did was blow the 5 year warranty by
sliting the sticker, popping the top, drilling 2 holes and tapping them to secure it in my 4U rackmount
then I made a hole in the bottom of the case for one of the vents,
so I could maintain the proper air draw throght the PSU enclosure

another note the PCP&C is rated at 510 watts, but that is as measured at 40C
if it was measured at 25C like most everything else youll see,
it would be a 600Watt with a peak output of 650Watt

yea- still made the offer tho-

I just ordered a custom one for my P4- switched because I decided it would be more fun building a ~1.6TB array than waiting for the 800mHz FSB Xeons to come out.. Of course 3 days after I got my 3.2 Prescott in the mail, the Xeons came out.. argh

http://www.hardforum.com/showthread.php?t=775056

Oh well- the P4 will work great for a while, I found this mobo:

Big Version of Gigabyte Ultra-64

which satisfied my workstation hunger (U320, 64bit slots etc)

Here's where I'm at right now; waiting for parts..

Big Version

C: - Seagate 73GB U320 15000rpm (program files) on the mobo controller

D: - 2 x Seagate 18GB U320 15000rpm RAID0-36GB
(swap/scratch/temp drive) on an Adaptec 3410S; had an
external enclosure at one time, might expand this to a
RAID10 array seem as though I have the drives.

E: - 4 x Seagate 200GB SATA drives RAID10-400GB
(documents) on the motherboard

A couple months down the road: -->
F: Future mass storage with 5 or more x 400GB Seagate drives and a
3ware controller in RAID5. ~1.6TB; well, >1.0TB at a minimum. Need to work out the power before I work on this array.

Directly from the horses mouth:

...
In 8-10 weeks we should have the TC800-EX that
would provide up to 66 Amps on the +12 Volt rail.

...

However, even with the TC800-EX we can provide
only 15 drive connectors maximum which would
normally be configured as follows:

6 SATA drive connectors.
8 standard 4 pin drive connectors.
1 standard mini drive connector.
1 24 or 20-pin motherboard power connector.
1 PCI Express Video 6-pin power connector.
1 ATX12V 4-pin CPU power connector.

...

Preliminary pricing for the TC800-EX is $490.00
and requires the PC case to be at least 20 inches
deep. The power supply will be 9 inches deep
instead of 5.5 inches deep for a standard ATX
power supply.

If you have any further questions please feel free
to contact us at 800-722-6555.

Sounds like a beast! This guy really helped me out and got my custom job rolling.

I've been really impressed thus far with this company, a real class act.

1 ATX12V 4-pin CPU power connector

however an EPS12V would require the 8 pin not the ATX12V 4 pin
Id custom order both in the harness if you can
the AG designation on my 510 denotes that 6 pin for AGP Pro

 

[jen4950]

however an EPS12V would require the 8 pin not the ATX12V 4 pin

Well- you'll notice he said 20 or 24 pin connector, which implies the 8 pin connector would be included with the 24pin PSU

The PSU we were trying to arrange was for a P4 and he mentioned that this TC800 model would be available in a couple months

 

[Ice Czar]

no ATX12V depending on the version is either 20 or 24 with a 4 pin connector

while EPS12V is 24 with 8

details-

 

[Ice Czar]

EPS12V is the Server System Infratstructure spec put out by Intel
and such boards have the 8 pin connector not the ATX12V spec 4 pin connector
in addition there are 2 kinds of +12V rail options depending on the total watage\option of the manufacturer

in Both the latest ATX12V (v2.0>2.2) and EPS12V spec there is a minimum of dual +12V rails
there is however an option for Quad +12V rails in EPS12V
and with such a monster Id likely consult on that with PCP&C
Isolating all those drives and the CPUs from each other being a good Idea

let me grab the spec differences (and retype them from the PDF )
something Ive been needing to do for the FAQ Im writing, but that isnt going to be immediate, so in a couple of hours

 

[Ice Czar]

of course that board you linked has Gigabytes proprietary take on this whole issue
the 6 phase Dual Power System, which is a unique VRM solution
and it has the 4 pin connector, but if you migrate to say my board youd also need an 8 pin

one of the hottest components on my board is the Voltage Regulation Moduals for the CPUs
they have better heatsinks than the chipset (Hypertransport AMD 5000 series)
everyone is dealing with the new spec a little differently (the switch from +5V to +12V to power the CPUs)

I'm intimately aware there's a difference between the two, hence having 2 $200+ PSU's on hand for one machine (1 EPS12V and the Custom 510 ATX).

But if you'll notice the EPS12V 24 pin plug, the only difference between it and the ATX 20pin plug is a set of 4 pins- (+12,+5,+3.3,Ground) at the end. And the 8 pin plug is the same as two 4 pins (4x+12, 4xGnd) in one plug.

So yea- there's probably a different rail configuration between the two, but as a practical matter it's a wiring issue more than anything.

Note to self: don't switch platforms after buying parts..

 

[Ice Czar]

are there 2 x 4 pin connectors? In your ATX12V wiring harness?
(I dont have an ATX12V v2)
<note to self> download PDFs drawings for all ATX12V supplies </ >

the dual \ quad rail breakout is an interesting option
here is an enermax spec for a quad

DC OUT....Rip&Noise...Tolerence...Rng1..Max/Min..Range 2.......Range 3........Range 4
+12V 1 ......120mV ......+5%,-4%..... 1.5A / 14A..... 0.5A / 5A.....1.5A / 14A... 0.5A / 9A
+12V 2 ......120mV ......+5%,-4%..... 1.5A / 16A..... 0.5A / 4A ....1.5A / 18A... 0.5A / 6A
+12V 3 ......120mV ......+5%,-4%..... 1.5A / 16A .....0.5A / 6A ....1.5A / 16A... 0.5A / 9A
+12V 4 ......120mV ......+5%,-4%..... 1.5A / 14A .....2A / 5A .......1.5A / 14A... 2A / 9A

[jen4950]

I was typing in shorthand-

The 8 pin is like 2 4 pins molded together- the 4 pins have 2x+12v and 2xGnd, while the 8 pin has 4 of each. White wire versus yellow- otherwise identical.

4 pin - ATX12V
8 pin - EPS12V

Anyway Mr. Matlab program of my own creation is not spitting out the right answer and I'm getting tired.. This sucks.

 

[Ice Czar]

I knew that the volatges where the same
Im trying to determine exactly what kind of clearance would be required to use an 8 pin on a 4 pin connector in another thread

and Im also trying to sort out how the different quad rails pin out for the FAQ
so if there was actually 2 x 4 pin connectors on all or a few stock PSU wiring harnesses
making them both ATX12V v2 & EPS12V dual rail compatible
Id really like to know

most of these supplies are dual spec, and say so, but few actually supply a connector list or drawing of the harness

If you'll look at that pic of my new mobo, you'll notice the IDE connetor gets in the way of the 24pin connector; and the power circuitry fan connector gets in the way of the 8 pin connector. Otherwise I'd use the EPS12V PS, or at least I tried. (been down that road.. )

[Ice Czar]

get the 24 pin and use a converter, those are readily avialable and will future proof you
the 8 pin to 4 pin converters however, is what Im trying to locate and or determine the actual clearences to use directly, or see if 2 x 4 pins are used or common

 

[jen4950]

eh- I'm ordering one with the SATA connectors I want.. save it for a future project
