Can anything support this extreme a setup?

[MillMaster]

I am building a new system this winter, and am having alot of trouble finding a powersupply that even comes close to being able to support it....

I am going to wait for an nForce4-Sli mobo, and throw a 53 or 55 into it, with a gig of ram. For now I will be running only a single 6800 ultra, but will want to put in another in the future. The OS will be running on 2 raptors in raid 0, the main storage will be off a promise sata-raid card with 4 300 gb drives running raid 5. Throw a dvd-rw, a dvd-rom, a fan controler, cold cathod, floppy, card reader, etc... and there is nothing that even comes close to being able to support the ammount of connections or power....

I was looking into the pc power and cooling 500 watt PS...

Also, what problems am I going to run into If I start to use molex splitters to add more and more stuff on? Any other power supplys that I may have missed?

Thanx in advance for any help...

i don't kno but czar will surely help u to the best of his ability. wait for his reply. he's a great guy.

Meh, i have a cheap antec 250w PSU powering 2 IDE hard drives, 2 optical drives, fan controller, 3x 120mm fans, cold cathodes, Radeon 9800 pro, 1GB ram, XP3200+...though I'm sure i'm pushing it...

though I plan on upgrading to a Fortron 530w PSU soon, I've heard a lot of good things about it, check it out.

i got a fortron blue storm 500 watt psu and am lovin it. it blows pretty cool air onto my comp.

start running numbers based on this

if the Turbo Cool 510s wont do it (and you dont need to deduct 1\3 of thier rated amps)
there will be a EATX 700 watt PCP&C released soon that will

as your component selection firms up we can get more specific

and there are plenty of supplies out there that will currently power alot more that
however they arent ATX12V PS\2 form factors, they are one of the various rackmount form factors

 

[Specialist[X]]

if you want to add on another ultra to your setup, what will you do with your old agp ultra? sell? and invest in 2 pcix ultras? wow... thats quite an investment.

question: czar, what were you saying about the atx 12v ps2 form factor? something about not being able to support that kind of output? do you mean atx 12v v2.0? please elaborate more on this as i have a neopower, and am concerned about the ability for it to support 2 6800GTs, along with a similar setup as millmaster.

 

[Ice Czar]

its not that the form factor cant support the likely load
its just that as of right now, most monster watt supplies are N+1 (Hotswap Redundants) fitting in 4U rackmounts
powering a dozen or so HDDs, and dually boards (NAS Network Attached Storage \ SAN Storage Attached Network)
like this 810W yours for slightly more than $1 per watt

your neopower will likely power a lean SLi setup, but if you start loading up on cards and drives youll go right past its ability
the new PCP&C 700 and 850 watts are EATX (Extended ATX}, with a deeper dimension
which most would have room for

MillMaster, I'll run some numbers tonight
in the meantime if you check in, look up if the Promise has a delayed spinup option for the RAID array

if i were to load up on say a couple of hdds, say like 3-5 or with a raid config, and sli setup with 2 6800gts, would i be able to get by without overloading the psu?

edit: when you say lean, are the GTs a bit too much? how many hdds and optical drives and whatever else i havent mentioned would be a bit too much?

Ive had a hard time tracking down any exact wattage requirements for the specific parts I want to put in but tell me if this sounds remotely close...

mobo - 25
cpu - 88
memory -14
hard drives 15 x 6
burner - 29
rom - 10
6800 - 76 x 2

pluss I figure about 40 extra watts for stuff like floppy, cold cathod, fan controler....

500 watts seems likes its cutting it to close... but im not really shure...

 

[shade]

is it me or does that 810 watt psu look extremely huge?

watts mean next to nothing its the amps per rail
specifically the +12V rail
and with an ATX12V v2.0 supplies each of the +12V rails

----------------------------------------------------------------------------------------------------------------------------

Do the math here: http://www.jscustompcs.com/power_supply/
There's a good chance you will need a bigger PSU than the 470..

And once again. Let's not forget that these calculators are absolute worst case.

well as far as calculators goes, that one sucks (sorry)
its very important to actually determine the amps per rail
and not all calculators are automatically the worse case senerio
I use > takaman's Power Supply Calaculator v2
which does have the option to set a utilization percentage, and to manually enter amp values for a given component
which is very handy if you have real world test values like
Power Consumption of Contemporary Graphics Accelerators: ATi
Power Consumption of Contemporary Graphics Accelerators: Nvidia
(all the better because they break out the draw between the AGP and the auxillary connector, which on an ATX12V v2.0 is on different +12V rails)
and various databases like Processor Electrical Specifications
(if the board has a +12V auxillary you add to the +12V otherwise it goes on the +5V rail,
and you convert the watts to amps for the appropriate rail, AMPS = Watts / Voltage)
or the actual spec sheets on the components (like say from Seagate)

that way Im able to run multiple calculations
first I do a "full" calculation, of all the additive maximums of the components
then for an ATX12V v2.0 supply or an EPS12V supply I repeat that for the +12V1, +12V2 and additionaly for EPS12V +12V3\+12V4 rails

then I run a "realworld" worse case senerio,
Its just as likely Im helping someone calculate a NAS as a lean gaming rig
so a "spinup" calculation is the first criteria
all the fans and HDDs\RAID arrays at 100% value and a 25% value for the CPU\GPU, often that will tell me if a more powerful supply is needed simply to boot or if the NAS\SAN need to employ a controller with a delayed spinup option
(common on SCSI controllers, and found on quite a few ATA)
once the fans and HDDs are spinning they will drop to 1\4 of their full rating, so I recalculate with that value as a static load, and throw in a 100% CPU\GPU and single optical (full spinup draw) for a worse case senerio realworld


Interpreting the veracity of a manufacturer is the tricky part
since we dont get to actually see the engineering test specs
which will typically say sometghing like
rated for full power at 25C decreasing linearly to no power at 70C
and your operating temperature being around 40C

generally I start with deducting a third off the rated amps for temperature
and then start to match to the baselines, factor in thermal considerations (PSU placement, type of thermal solution for the rig,) and special factors like overclocking or usage patterns (NAS\Server\Workstation\word processor ),

when I actually make recommendations however I typical build in a healthier safety value than the "real world" worse case senerio unless someone has specifically stated they are running a UPS
--------------------------------------------------------------------------------------------------------------------------
ffor ATX12V v2.0
+12V1 will be CPU, mobo, PCI Cards, fans attached to the mobo and the AGP slot the 24 pin main power connector and Aux +12V mobo connector

+12V2 will be all other connectors including the Aux to the Video Card, drives, fans, lights, pumps ect
----------------------------------------------------------------------------------------------------------------------------
EPS12V supplies are generally for Dual CPU Servers and Workstations, and break out like this

EPS12V 6.1.1 12V Power Rail Configuration

There are two types of 12V rail configurations for systems: 'Common plane' and "Split plane' processor power delivery. The 'commob plane' system has both processors powered from a single 12V rail (+12V1) from the power supply. The 'split plane' system has both processors powered by seperate 12V rails (+12V1 and +12V2) one dedicated to each processor. The system in both cases, has an additional 12V rail to power the rest of the baseboard +12V loads and dc/dc converters. +12V1, +12V2 and +12V3 should not be connected together on the baseboard to ensure that 240VA protection circuits in the power supply operate properly

Table 6: 12V Rail Summary
........................................................................................................................................................................................
Common Plane System........................................................Split Plane System
+12V1........Processors.........................................................+12V1........Processor 1
+12V2........Baseboard components other than processors.......+12V2........Processor 2
+12V3........Drives and peripherals..........................................+12V3........Baseboards and components other than processors
...........................................................................................+12V4........Drives and peripherals

and will have an 8 pin Auxillary +12V mobo connector (2x4)

I saw a forum member that hooked up a hard drive to every single connector of his pcp&C 425 deluxe (something like 10) and ran a hard drive stress test and prime95 and the same time and the voltages still didn't vary more than 1%. Imagine what a 510 deluxe can do!

Actually, according to pp&c's warranty:

The pcp&c 510 deluxe is guaranteed to run a dual cpu system with up to 12 hard drives.

So I guess that's what it can do

I'd say it'd be enough for your rig. Keep in mind its really a 650w psu (pcp&c rates differently from the other manufacturers)
