Why does WinVery.com still not have an untrustworthy or scammer tag? 
In offline world he would be dead by now... Yes.

That escalated quickly.

Nice, have they all been shipped already then? *bounce*

I've had no call.

I'm currently in Shanghai, but will be leaving tomorrow evening. I asked if it was possible to deliver it by that time.

Gotcha Good service for you then

[lan787]

This is fantastic service. Honestly I did not expect it was possible.

any one looking for power supply. There is very nice PSU used in CCTV cameras, exactly 12v 10A. I think it will be easy to find CCTV guys almost anywhere.

750W Corsair won my vote, 62A on a single rail, should happily supply four of them.

Does it have 8 molex? If not I'd be careful, I don't think we can power a blade with a single model worth of cables and deliver 10A.

I tried those.  I wasn't happy at all.  Very noisy, poor efficiency, and power factor.

I plan to use my home server PSU. it is 350W The server itself drains <100W. Will the PSU handle this?
 Is two molex connectors enough for one blade?

I'm planning on using the PCI-e connectors (it has 4) - chop the plugs off and use the wires straight into the blade connector blocks. For some safety factor I could use a molex cable as well into each blade but I don't think that'd be necessary?

I'll just monitor the wire temperature like a hawk for the first few hours

blah can't edit posts..

Corsair CP-9020015-UK CX 750W Power Supply (PSU):
Four PCI-E (6-pin / 8-pin)
Eight SATA
Six peripheral cables (4-pin)

I think there'll be enough to make it work

I'm thinking about something like this:  http://www.newegg.com/Product/Product.aspx?Item=9SIA1KT0H17983   Would that be any good?

or http://www.brainydeal.com/DC-12V-30A-360W-Switch-Power/M/B006IO72K8.htm#wbaCustomersReviewsWidget  if you need more watts

Those look sexy.  And it allows you to buy big, proper wires so they dont heat up.  Remember, if your wires start to heat up while in use, you need some bigger ones.

Looks alright in theory but not much mention of power efficiency I could see from a quick glance.
With PSUs you generally get what you pay for in terms of quality of the components inside.

I trust Corsair and having the 80PLUS rating (even if it is only a bronze, thats good enough for me) is just further reassurance.

I don't know how sensitive these blades are to voltage fluctuations but cheap PSUs can sometimes be be pretty susceptible to voltage drops under high load - and you'd be running pretty close to the line on that 10A one. But then, the 30A one isn't much more expensive, so the 10A one could be better quality in the first place.

[simtel12]

According to Toms Hardware, the pins on the PCIe auxiliary power cables are generally rated for 8 amps.  With that in mind, if I were to use a a decent PC PSU like that Corsair, would I have to buy separate connectors to handle to the load, or would it just be easier to cut off the connectors and use the bare wire?

Back on the switching PSUs:  The SE-200-12 looks pretty solid for powering a single blade:   http://www.meanwell.com/search/se-200/default.htm

For PSU you probably want the NXZT Hale 90. Its really a Superflower OEM enterprise-grade PSU that has a beefed up fan. Its the only PSU on the market thats any good anymore, now that OCZ bought PC Power and fucked up all their products (I miss the original Silencer).

BTW, as for amperage per pin on various connectors, you want to read this: http://www.playtool.com/pages/psuconnectors/connectors.html
