Hiya, I have a server with lots of drives requiring 4-pin molex, I have several PSU's covering this ATM but I would like to combine into one, Using minimum 20xmolex I dont think there is a PSU with that many, So maybe one with 10 on that I can split? Best on one rail? (asking not telling)
Its pulling max about 600w around 40A on the 12v (Most good 750W cover this) So I need something bigger than that to handle poss additions.
I see lots of 1KW 100A PSU's with 14 SATA but only 6 molex, I dont feel safe using 3.3v converters to use these.
If you have any other options please give me a shout, I need fairly quickly too, Probably best in the E.U. as shipping from elsewhere would be too much and take too long.
BTC waiting, I will only send to approved escrow or send on receipt of goods
Regards
EDIT - thanks for comm's but I'm out of time on this. Gotta buy one.

MMmmmm, That's a mighty one, Also has 16 SATA But single rail is good!, Can I just sata-molex the rest? Is there a reason why sata carry's the 3.3v rail? Molex has 2 power pins (one 5V and on 12V pin), each can deliver 11Amps for a total of 22Amps. The other 2 pins are ground wires...
SATA power connectors has a total of 15 pins of which 9 are power pins (3 x 3.3V, 3 x 5V, 3 x 12V). Each pin can carry 1.5Amps for a total of 13.5Amps. BUT as there is as yet no use for the 3.3V pins the effective power available to drives is only 9Amps. From this quote, Am I right in saying I can use adapters, But say if one output has 3 SATA, I can only draw 9 amps Totally across the 3? On some PSU's you see a mix of SATA and molex on one output lead, Anyone know how this works? Also to cut a long story short, I wish to pay in BTC, I am not bothered about new, Someone must have one lying around after selling all the GPU's.

My brother has a 700 one he is looking to sell, he wants to sell his rig as a whole.. but with asics coming out theres no way anyone would want to buy a 600mhs rig for £600.. You can see his rig here with the psu https://bitcointalk.org/index.php?topic=220459.0

Hi, sorry for the OT, just interested in servers Can I ask what kind of setup is that? 20 harddrives in one case? With room to grow? Sweet I've only seen that many in dedicated SAN boxes. Cheers Pete

Cheers Pete Its just a 20x1TB RAID10 setup, I need the extra power as I need optical drive's added on at some point, The case is made by a friend who is a good metal worker, It has 40 5 1/4" drive bays in a 4 rows of ten config, Each on rails to slide out for easy mounting, With well placed air in/outs and Mobox2 on rear backing plate , He has incorporated space for 2 ATX PSU's, One either side. So in theory It can house two separate servers, My main problem is getting certain OS's to see them all, LOL hx 750 psu 100 gbp ebay 1 12v rail
I need a bitcoin transaction, The more I can not use flea-bay the better.

Impressive! I was thinking no off the shelf case can take that many drives Kudos to your metalworker friend. I don't suppose the OS you mentioned comes from a Redmond-based company?

Do modern hard drives still use the 5v delivered via the molex plug?

Not sure, I have confirmed in another thread that I can use SATA to molex adapters providing there is ample watts/amps. So I still need a 1KW+ PSU with a total of 20 connections, Bought with BTC, If I don't get one here soon I will have to exchange some BTC and buy one off the bay.

Thanks for the offer, But no point in a middle man for me. I will close this for now, I was hoping someone would ship me out one Monday morning.
