The amount of power plugs (or barrels) which you can connect is directly determined by the amount of watt you have available. (Amount of watt you have) divided by (the amount of devices you want to power * the watt each requires). If the result is less than 1.00 then Bad. If over 1.00 then Good

Thanks, Ok so lets just say I have 1200watt available .. What I was asking is will 1 single 6PIN Pcie connector going into 10 Barrels -be sufficient for 10 v3modded grids? Since they are like 20-25watt each thats like 250watt max On a single 6PIN, .... I have a few here that came with my grids, 1 PCIE (6pin) going into 10 barrels, but this was created for unmodded pods which is why i am not sure if we can still plug 10 in if they are modded.

Single 6-pin PCI-E Connector is rated @ 75W ...12V power delivery...about 6.5 Amp = 3 OC gridseed...

Single 8-pin PCI-E Connector is rated @ 150W ...12V power delivery...about 13 Amp = 6 OC gridseed...

Hope it helps, buddy...

I keep hearing this and I need to once and for all get pure clarification about this - I have heard exactly what Zig has said any times so
Thanks zig ,

But this is where I am totally confused, I am a GPU miner recently moving to mostly asic with some GPUs left for N-Scrypt, My Peak GPU rig was 2 x Motherboard with 7 x 290x on each 14 x 290x Cards and most of them OC = LOT OF POWER DRAW lol , now this theory of 75 & 150w I cant help but think this cannot be correct.

heres why, I have tested 1x 290x on 1 Single PCIE which branchs off into a 6PIN + 6+2Pin and I am talking these are on day and night non-stop and this is just over 300w with a some minor OC - 1 single 290x overclocked can suck more than 300w On its own.... Infact I have heard of OC 290x sucking as much as 360w On there own. And this is all coming from 1x 6pin and 1 x 8pin

Power[edit]
All sizes of ×4 and ×8 PCI Express cards are allowed a maximum power consumption of 25 W. All ×1 cards are initially 10 W; full-height cards may configure themselves as 'high-power' to reach 25 W, while half-height ×1 cards are fixed at 10 W. All sizes of ×16 cards are initially 25 W; like ×1 cards, half-height cards are limited to this number while full-height cards may increase their power after configuration. They can use up to 75 W (3.3 V/3 A + 12 V/5.5 A), though the specification demands that the higher-power configuration be used for graphics cards only, while cards of other purposes are to remain at 25 W.[9][10] Optional connectors add 75 W (6-pin) or 150 W (8-pin) power for up to 300 W total (2×75 W + 1×150 W). Some cards are using two 8-pin connectors, but this has not been standardized yet, therefore such cards must not carry the official PCI-Express logo. This configuration would allow 375 W total (1×75 W + 2×150 W) and will likely be standardized by PCI-SIG with the PCI-Express 4.0 standard. The 8-pin PCI-Express connector could be mistaken with the EPS12V connector, which is mainly used for powering SMP and multi-core systems.

there is the Power spec's per Wikipedia. so the Slot itself offers up half of the power. and then the connectors offer the additional power needed by the card.
