Best PSU for ASICMiner Blades

[goastler]

Hi,

I've getting given a couple of Blades and they aren't coming with PSUs, so I'm in the market for some. I was wondering what the best PSU I can buy for Blades is? Obviously they have certain current requirements from the PSU, so that limits what PSUs can be used, but I was also wondering whether it would be cheaper to buy a high spec PSU and power multiple Blades off of that rather than singular PSUs for each Blade.

Thoughts?

Also some links would be appreciated

I would say the 1000W PSU with backplane is your best bet - not expensive and will do the job cleaner (i.e. less cable management)

The backplane has 10 slots I think but you are probably better off stopping at 8 or 9. I ran 9 for a while with no problems. Maybe go to 9-10 if you are running on 240 V (the PSU spec has higher max output at 240 V, and it will certainly run cooler in any case).

Okay, I'm not ready to buy a backplane right now since they are expensive to buy in to the UK. I'm waiting on a used one to crop up on ebay soon, then I'll grab it then. What I was getting at is the best setup of standard PC PSUs for the Blade?

I have one I could sell you. I don't know a reasonable price, but I'm open to suggestions. I'd have to ship it from the USA though.

If you only have a couple of blades you can use any reasonable PC PSU, although you probably want 80 PLUS Gold, 80 PLUS something at a minimum. If you want to get a whole bunch of blades on one you will need a 1000 W or 1200 W server PSU. Corsair AX1200 is good, but there are other good ones too.

Yeah, unfortunately customs charges with VAT in the UK make it so expensive to import stuff, and I've been bitten by that already so I'm not going to do it again.

Thanks for the other advice though, that's what I was after Cheers!

What is the power requirement for each blade?

When choosing a PSU, look at the spec. on the manufacturer's website to make sure it provides more than enough power at the voltage needed (usually 12 volts).  Bear in mind that the total overall wattage for the PSU isn't always available on the 12 volt rail.

Don't buy a dirt cheap PSU, even if the specs. look right.
