Sold all my miners, thank you to everyone who purchased from me. Now I've got all these PSU's to sell. Also a couple PDU's.

Shipping through Canada Post, escrow welcome(you initiate it and pay fee). OgNasty pref.
Bitcoin only.

7x EVGA SuperNOVA 1300W G2 PSU's ( PSU/6 PCI-E cables/1 Power Cable/1 PSU Cable    Asking $150 CAD each plus shipping.

2x 208V 30A APC Rack Mount PDU   NEMA L6-30 plug end, 11 available C13 oulets on each (both PDU's have one spot that was damaged when I bought it)   Asking $60 CAD each plus shipping.

$500 Canadian dollars, correct? Also where in Canada are you located? (Reason I'm asking is maybe local pickup is possible)

Don't forget customs fees/ I just got hit with them for 2 I bought the other week.  :-X

Won't be any. I already paid them when the miners entered Canada and I am not willing to ship outside of Canada.

I am vouching for this seller as being legit and honest. Bought an S2 off him.

Transaction went very smoothly and was shipped very fast.

Would you sell me one or two for 420 + shipping to Toronto?

Won't be backing the price down. I believe this is a good deal for both buyer and seller, the amount of SP20E's I have left will be updated throughout the day once funds are escrowed and I begin shipping.
There is room for negotiating a price on the S4 and SP10 just to get them moved.

2 SP20s @ $1000 + shipping heading my way using OGNasty as escrow. Thanks, teeGUMES!

Got my tracking number earlier, looking forward to receiving them!

How about $500 with shipping to Toronto included ;)?

If so I could buy all of the remaining ones.

Also what are you asking for the PSUs?

Tried that, didn't work.  :P

Dang, ohwell. I'd be willing to pay for shipping if it was around $25 per unit. He can put them in one big or crate and save on shipping costs.

This is a good deal people. Get on it.  8)

I'm all over this. BTC in hand and ready  8)

I looked into a larger box with another member here and it was not much different. It seems the major factor is the weight.
The original packaging keeps these things steady through shipping, you'd be giving up a lot of stability and looking at possible damages to the units by combining them. I figure whatever you'd be saving on shipping if any, I'd be spending on bubble wrap and stuffing.

The PSU's I'm looking for $150 each. If you take all 7 I'd be willing to eat the shipping cost on them.

Hmm, let me think about it for a bit though. I normally use HP server power supplies that cost around $75 each for 1200 watts. I'd need two of those to power one SP20 or 1 and a 1/2. If you could sell them for $130 each that would be ideal.

Not trying to make teeGUMES lose a sale on the PSUs, but the HP 1200w would be fine. Running the SP20 full out pulls ~1240w at the wall, so 1091w from the PSU assuming gold efficiency. That being said, the EVGAs are beasts, you can't go wrong with them. 8)

100% correct.  The cubed weight is less than the actual weight on mostly everything we deal with in BTC hardware, don't sacrifice the original box even if it did save a couple bucks, they are built right.  I made that mistake with thedreamer (sorry buddy), won't do that again.

Also, Allinvain, even in the right environment with cheap power, running these over 1550 GH/s kept them hotter than I was comfortable with for longevity.  Running these at 1500-1550 GH/s draws around 1,000W DC, and the gains from going higher weren't worth it IMO.

Maybe you should try shipping it by Greyhound.

At my old work we used them and they are fairly cheap. The only issue is that you must drive to a Greyhound shipping depot to drop it off and pick it up. For heavy and large items as these miners, these might be the absolute cheapest way to ship across Canada.

Most of mine are running at stock, but I think it would be wise to underclock them slightly for the sake of efficiency. I think these are ok with running hot though, but I could be wrong. The exhaust temps are always high and I believe they were designed like that cause hotter slow moving air is easier to exhaust.

So far all of mine have a starting voltage of 0.69 and a max of 0.75. With that setting nearly none of them run at over 1600. Most run at 1550 to 1570.

I gotta get a 220v power meter or hook one up to a switched PDU and see what each one consumes currently at the wall.

What voltage do you run yours to get 1000 watts DC consumption? I think there is an efficiency chart SP-Tech published somewhere though.

Starting voltage between .685-.69, using wattage per loop to limit instead of max voltage.  I would keep the rear two loops a little lower wattage to keep them from getting too hot. I think I had the loops at 265W front and 245W rear, I can't remember exactly. I'll see if I have a screenshot from when I had them running.  I sold them all too soon with these last few cushy difficulty changes :( I kept all chips below 100C, and fans @ 100%.  I noticed a few percent decrease in power consumption @ given hashrate by dropping the temps by ~20C with fan at 100 instead of on auto setting. I do not trust the auto setting, keeps the chips too hot IMO.

That was quick teeGumes! Congrats, thanks for the easy transaction on the S4/Sp10.

Cool, thanks for the info. I will consider doing what you did once the temps start rising in our data center. I just hope it will be a mild summer.

Also some run better than others.

Out of the 8 I have now running, 3require about 0.1v more to get the same speed as the others, alas use more power and heat.

3 of them can under clock below 0.5 efficiency so they can hit higher speeds at lower wattages. I haven't tried full blast yet, but should hit 1650 with ease.

selling PSU's and PDU's now. All miners gone. Thanks guys.

How much would shipping be for the PDUs? Use the same address I sent you for the miners.

$25 Regular Parcel, easily shipped in 1 box.

Wow, that's a pretty good shipping price considering their weight and length. I'm 99% I'll take them. Let me double check with my business partner.
