DARK POWER PROp8 1000W

[servie]

Hello

My first post.

I want to build a pc with 20 HD, or more, and want to use this powersupply DARK POWER PROp8 1000W

It is a modulaire powersupply and you can plug 4 harddrives on one string. By string I mean the modulaire cable.
So now is my question can there be more harddrives on one string if I make my own ?
Or will I blow up my supply ?

How many harddrives can there be attached to that kind of powersupplies ?

Sorry for my bad Englisch but I'm just a Dutchboy.

Hope you can help me out here.

1000W just because you want to spin-up 20 HDDs; and after that you use only 200W? Don't you think that's a bit excessive money wasting?

Either invest in staggered spinup or pick a PSU with combined +12V rails, 850W should do. But that pretty much does mean you have a high power consuming NAS. With NAS it's usually advisable to build is low-power; which is possible by making some adjustments.

So perhaps you should explain to us:
- your exact setup
- what kind of HDDs
- exact function of this machine
- why 1000W?

You can connect about 10 HDDs to a 400W PSU; 800W should be able to handle 25. But not if you pick one of many PSUs with separate +12V rails. Then it will power off because of overload. You need a PSU with COMBINED +12V RAILS. I thought corsair had a nice PSU with that around 850W.

You are using power splitters, right?

Setup :

MB Gigabyte 890GPA-UD3H
CPU AMD Athlon II X4 640
MSI R5770 Hawk graphics
10 x Western Digital Caviar Green WD10EADS
Raid controller
DVD rom

I use this machine for everything.
I run win 7 and play games, watch movies and want it to use for central data storage.

Why 1000W, a HD has an high spinof, I thought they say about 30W.
And I want some extra room for more HD's

Do you meen this powersupply : http://www.corsair.com/products/hx850/default.aspx
To bad they use the same colors for sata cable so if I want to change anything I dont know wich wire is wich

Wouldn't it be better to setup a dedicated fileserver, instead of having an all-in-one monster machine? Just a thought.

What kind of RAID controller do you have?

Some HDs have indeed 30W spinup during a few seconds on boot. But you can solve that either by:
- Staggered Spinup: don't let all disks spinup at the same time. (requires support in your controller)
- use lower rpm disks with less spinup current required

Instead of a 1000W with multiple rails you might want to trade that in to a nice 60A +12V like Corsair has i believe. That likely will be better for providing spin-up current to HDDs than multiple rails would.
