Hey all. Most of you use PCP+C, and you all rate them highly...PCP+C prob get sales indirectly coz of all your positive words here BUT.... there has to be some alternatives to a PCP+C, hasnt there? So far, what i`ve found (definately not gospel, or the unquestionable truth) is that split rail PSUs are not really suitable, even if the total ampage for the 12V rail is high. I`ve only tried one PSU that has powered my phase rig stably every time I`ve powered up, and that was a Tagan with one large 12V rail. Even at that, I couldnt overclock further, suggesting that the PSU was at its stable limit, though i would be willing to admit the CPU might have maxxed.

Please can we have a list of all the PSUs that are powerful enough to keep phase rigs or Phase/SLI (even worse!) rigs running and overclocked. Discussion also welcome. I (or any mod, obviously) can add to the lists of suitable and not suitable PSUs, though I suspect most of you already know what`s suitable.

Sorry if I`m doing wrong by posting this without clearing this with the mods/ admin, and no comments are aimed at putting down any PSU, please remember we are not "normal" computer users, "normal" PSUs need not apply! Thankyou

Layout Edit: Has been split into sections for Vapochill and Mach PSU suggestions. Only Vapochills need a beefy 12V rail, so split rail will be acceptable for Machs.

VapoChill

Suitable

Tagan 480U-01, single +12V rail, 28A

PCP+C 850, quad +12V rails, 17A each

PCP+C 510w SLi/DLX, single +12v rail, 34A peak, 5v 40A and 3.3v 30A,adjustable rails

OCZ Powerstream 520w, single +12v rail, 33A, 5v 30A, 3.3v 28A,adjustable rails

Borderline (is capable of powering, but not consistently)

Enermax EG701 Rev. 1, split +12V rails, 18A, 17A (35A total)

Unsuitable (only PSUs that you would think could cope, but cant)

Mach

Suitable

Tagan 480U-01, single +12V rail, 28A

PCP+C 850, quad +12V rails, 17A each

PCP+C 510w SLi/DLX, single +12v rail, 38A peak, 5v 40A and 3.3v 30A,adjustable rails

OCZ Powerstream 520w, single +12v rail, 33A, 5v 30A, 3.3v 28A,adjustable rails

OCZ Powerstream 600w, split +12v rails 18A, 20A (38A total), 5v 46A, 3.3v 28A

Enermax EG701 Rev. 1, split +12V rails, 18A, 17A (35A total)

Borderline (is capable of powering, but not consistently)

Unsuitable (only PSUs that you would think could cope, but cant)
 
add the 850watter pp&c monster, the ocz powerstream has got to be worth a mention...

and do mach 2s not have external power? i was able to power my mach1 with a kettle lead which meant my psu wasnt bothered :)
 
The PCP+C has 4x17A 12V rails, yea? When someone adds a PSU, please can they add the 12V rail specs, seeing as those matter.

If Mach units take their own external power, that moves the goalposts a bit... put that one down to my lack of knowledge about the Mach...
 
i can only say that for the mach 1... not sure bout mach 2 we'll have to wait for some experts... id post more psu's but cant vouch for them personally running a phase rig and powering it...
 
PCP+C 510w SLi/Dlx - 12v 38A, 5v 40A and 3.3v 30A plus adjustable rails

OCZ Powerstream 520w - 12v 33A, 5v 30A, 3.3v 28A plus adjustable rails

OCZ Powerstream 600w - 12v (2 - 18A and 20A), 5v 46A, 3.3v 28A

Just some other recommendations :)

i expect the Tagan 530w would prob be up to the job as well
 
Thanks Firelord! Some of your additions are split rail with only a bit more power per rail than the Enermax. There could be a bit of a strange divide coming up. Dazboots does fine with his Enermax, whereas it just doesnt happen for me. Hmmm. :)
 
K404 you run a Vapo don't you that require a beefy single volt line as the Machs aren't powered from the PSU so the split rails isn't an issue on the Machs but rather the vapos thats use a 12v compressor
 
well it would be good to have a thread with PSU recommendations in but perhaps have some for vapo specific and then everything else! Least then it collates the info
 
See...I dont mind looking a bit stupid now coz I`ve learned something :) Will try to change the layout of the 1st post before I head off to hell...err....I mean work. :)

Cheers Firelord

My 600W enermax (the one that's available in an SLi version but not the SLi version) was really not up to the task of powering my computer. Just got my new PCP&C though. I'll see how much of a difference there is.
 
Kenny u opened up a can of worms here mate.

Originally with Vapo's that have 12v compressors and Antec550w would handle the pace - back in the days when AGP was king and 9700's and 5800's were released.

Now it's a lot more confusing - on split rail you need to understand how they are split and take note here guys:

Specifically on the 850w unit:

2x 17a rails are for the MOBO (dual core ready)

1x 17a rail is for PCI-Ex2

1x 17a rail is for everything else (drives, vapo, fans watercooling etc...)

Now this is all relative to other units that have split rails, you need to know how those rails are distributed - sometimes careful selceting what connects where will allow you to maximise the useage on each rail.

You can add OCZ Powerstream 600w to your list.

The Coach
 
If I`ve opened up a can of worms, that means it probably needs to be discussed ;) I understand there will be not many set rules, and it will depend on the graphics, the disk setup, the mobo/CPU etc etc but after the Enermax incident (and now I know why Mr Dazboots recommended it...he uses Mach cooling which doesnt reply so much on the PSU) I thought it would be an idea to have a vague list.

If a PSU is split rail, is there any way of telling which molex are taking power from which rail, or does it not work like that?

Kenny
 
Don't really know much about them. Come people rate them higher than PCP&C. I think they have 45A on the 12v line. I also think they're quite expensive.

People on XS use them
 
Hmmmm. Never heard of them. Please could you do some scouting and see what you can find? Is that a single +12V rail????
