Power related question

I have a OCZ ZX 1000w PSU. I have recently started folding again on my computer with a ASUS GTX780 DCU2 OC and a i7 970 at stock. Before I was running 2 GTX 460 Hawk Talon Attack GPUs and folding on those with a i7 970 at stock.
Do I have enough power to handle the 3 gpus and processor folding?
I do not have enough pcie 6+2 connectors for the motherboard supplemental power connector and the cards so where should I use a dual molex to six pin adapter, or do I not need one?
Should I use the dual molex to six pin adapter at all, or just stick to 2 cards?

Thank you in advance, hopefully I don't sound too newbie =)

NEVER NEVER NEVER use a molex to a 6pin adapter. If you don't have enough connectors just get a new psu. Besides thats a OCZ psu, they are not a very reputable brand. If anything just use your 780 to fold. I'm no expert but i'm pretty sure a single 780 can fold better than 2 460's.

Do I even need to use the motherboard six pin power connector? That seems to be the real mystery for me at the moment.

It doesn't do much. Not worth it since it looks ugly. If the GPU needs more power it takes it from the PSU. On the board it can only give 75watts of power through to slot. Pushing more power through it is pointless since it can only transfer so much at one time anyways.

How does the power work then if 2 cards both need 75 watts of power from the slot? Why is the connector there at all? Why are there 24 pin connectors melting from power draw? Sorry I am really confused.

 

[NeverBackDown]

Each slot can give power, its there because they can really. It makes no difference to OC'ing the cards when pushing volts. So its there for some odd reason. Never heard of a 24pin connector melting..

Do you know of anywhere where I might try looking for a answer? I have been searching for 2 hours. Either I am terrible or no one has said anything.

I'd fold with the single 780, the 460s won't be worth it. That PSU, as long as it stays reliable, is way more than enough volts for your CPU and graphics card. I don't bother folding on CPUs any longer as the PPD isn't worth it IMO. You'll have to see how yours does as you have 12 threads to play with.

What 6 pin power cable are you referring to? The one that connects to the graphics cards? You say motherboard, but that would be a 4 pin or 8 pin (2x 4 pin connectors). What motherboard do you have?

Do not use a molex adapter

Mobo shouldnt need the extra cable adding but then you do have a terrible PSU anyways.

Far too much wrong in the thread Im off for a shower I feel dirty!

How do I have a terrible PSU? Jonnyguru gave it a 9.5

There are far to many members on OC3D who have had bad experiences of failed OCZ PSUs, I'm the most recent, 2 weeks ago my 500w OCZ ModXstream went pop and decimated my rig, killed my GPU and SSD, I thought it was a good PSU to start with, it had lasted me 3 years and suddenly bang!

 

[bluethunder]

So then I should probably replace it then?

 

[NeverBackDown]

Well on this forum we will advise you to get a new one. No one here trusts OCZ. Largely because they had a product failure rate so high at one point for quite a while.

Okay I will look into replacing it with a Corsair AX 1200i. How at risk am I right now running it? I bought the PSU in 2011.

A lot of their products failed constantly and replacing them did not solve the problem.. It was mainly with their SSDs and PSUs. If you want it then keep it but don't replace it with a 1200i.. thats way overkill. Just stick with a 650watt unit if you only plan on running with one 780.

 

[bluethunder]

I don't want it if it could kill my rig and cost me a bunch of money. I would rather just replace it before that happens. In the future I will probably be running 4 cards and water cooling the whole computer. Feels like I have a time bomb in my computer now. Where are the posts on the forum of the bad PSUs? I have searched and can't find anything.

Well here's the story. http://www.extremetech.com/computin...o-acquire-assets-but-warranties-could-be-lost

Also why 4 cards? Benchmarking? If its gaming then ya don't even think about going above 2.. after that they don't scale well and performance can actually drop. Liquid cooling a 4 card system will be very expensive and you will need a massive case and motherboard to fit all that.

I know OCZ is dead but I was looking for stories of bad OCZ power supplies. I do believe they are crap I am just trying to figure out which ones were the biggest piece of crap and how much crap is mine. lol
I haven't totally figured everything out yet, but I imagine I will get whatever new rampage board comes out maybe the black edition one, and probably a 760T case with as many rads as I can fit in it. I plan to use 4 cards for folding and don't expect more than 2 to work for gaming if 4 work great but I will just scale back till it works. I'm not really worried about the pricing of anything.

On a scale of Explosive to Crap, yours is "pretty crap" from what I can find. I'd personally look at Superflower or Seasonic for PSUs as well.

What are some places you looked at?
