Hey all, i have been having problems with my psu not powering my rig and the power keeps cutting out.

Suppose it was too much to ask for a 600 watt psu to power 2 260 gtx's supprised it lasted as long as it did.

So i need a new one. Price range is between 80-110 pounds.

A few requirements, if possilbe i would like it to be able to power my 2 260 gtx without the need for spliters. So it would need 4, 6 pin pci-e conectors. Also the cables will need to be long, i have a antec 1200 gaming case the psu sits at the bottom and would like the cables to go behind my mobo for cable managmeant.

It will need to power my sli 260's a e8600 @ 4ghz p5n32 sli mobo 2 hard drives and various case fans.

So i am guessing 800watt+ to be safe. I know very little about psu's and what all the rails and stuff mean so i'm in yours hands treat me good :)

I'm not botherd about noise or anything.

You mean 4 6 pin PCI-E connectors, right?

The PC P&C 750W Silencer comes with 2 6 pins and 2 6/8 pin. At least the SLi edition does, probably the Crossfire too.

Edit : I have no idea on cable length

Go for a Kilowatt PSU, so you wont have this issue again in 1 years time. Tagan do some nice ones.
 
hmmm on my psu it says i have the 700 watt one, shouldn't that be enough? I'm pretty sure its my psu cause as soon as i took the other graphcis card out the power stoped cutting out.

Do psu's lose there power over time ?
 
I like the price of the corsiar tx750, however is it gonna be enough, my current psu is 700 watts. I've had it well over a year though and its almost constantly on, so i dont know if the power output has gone down over time, can this happen?

I have notice the pc power cuts out at certain points, i've been using crysis warhead as like a test and theres a part in the snow level, where a big alien/monster thing comes from over the mountin and you and your sqaud have to take it down.

It seems to do it when the alien thing pulls you towards it the power seems to cut out around that point. I tried this same section again with just one graphics card and it was fine.

So am i right to assume its psu at full load? If one of my cards was faulty wouldnt i get a crash or bsod instead of the power just cutting out?
 
What make is current PSU!

Just done quick recky on extreme PSU calculator to give a ruff estimate, this comes out at 496w, a 750w will more than powerfull to run your system, even a Corsair 620w will be fine, but only comes with 2 pci-e leads.

OCZ GameXStream 700w Silent SLI Ready ATX2 Power Supply is my current supply, so that should easily be enough also.

it might not have enough amps on the 12v rails to power the GTX260's..

Like i said i know very little about psu's so thats kinda double dutch to me, i went sli in the summer is there any reason it would start playing up now after all this time?

I'll try both cards seprately tommorow to rule out it been a faulty card.
 
I think i have found the problem.
I tested both cards seprate and they both worked fine.
I was using the nivdia beta drivers, so i tried the current nivdia drivers and it didnt crash durring the crysis section. So hopefully its sorted now, time will tell after further testing.
 
Arrrh spoke too soon, after a few hours i did a crysis benchmark and it turned it self off again :( Is there anything else it could be oher then the psu. My overclock and cpu are stable prime tested, so it cant be that, i have tried differant drivers, and tested the cards on there own so it cant be that.
 
your overclock may well be prime stable ...but try everything at stock just to rule it out.
