cherritaker Posted January 1, 2011 Share Posted January 1, 2011 I'm planning on building a new server for the first time i want to use a couple of spare parts i have laying around for starters i would like some input on this PSU i have in my current case its a Raidmax 630Z with these specs. This is a direct link to it http://www.frys.com/product/6030458?site=sr:SEARCH:MAIN_RSLT_PG * 630 watts total input * A huge 135mm blue LED fan * durable black satin finish * 20/24 ATX Main power connector * Smart Modular Cooling system * 6 x ATX 4-pin Molex connectors * 4 x SATA connectors * 2 x 4-pin floppy connectors * 2 x PCI-Express connectors * Hexflo honey comb cutouts for maximum airflow * High grade black mesh wrapped cabling Quote Link to comment
BRiT Posted January 1, 2011 Share Posted January 1, 2011 It's a bit of a mixed-bag because it has Split 12Volt rails. Typically one rail is dedicated to connections which are unused in an unRAID server such as the PCI-Express Graphics connectors. You only have 22 Amps on the 12 Volt rail to supply all that's needed for the motherboard, cpu, memory, fans, and hard-drives. In essence this PSU provides less power than some quality single-rail 330 Watt PSUs. To give you an idea of power usage, some green HDDs like the Seagate 2TB 5900RPM uses 2 Amps on spin-up while the 7200RPM drive uses 2.8 Amps. The Hitachi 7200 RPM drive uses 2 Amps on spin-up as well. This means even without needing to run the motherboard/cpu/memory/fans, you can barely power 10 hard drives even if you use lower power requirement models. Quote Link to comment
cherritaker Posted January 1, 2011 Author Share Posted January 1, 2011 Will this work for the meantime since i am on a budget currently using the dns321 too. Just need it to work with the free unraid until i can buy the license for the pro version and more HDD's. Also how would this psu from newegg do? http://www.newegg.com/Product/Product.aspx?Item=N82E16817139018 Quote Link to comment
Joe L. Posted January 1, 2011 Share Posted January 1, 2011 Your old power supply will do fine with 3 disks. Quote Link to comment

As mentioned do not go over 10 drives on that supply though, and preferably not over 8-9. The PSU you linked to on newegg is a very good choice, and you should be able to run 15ish green drives off of it. Quote Link to comment
