Am I in Danger of Frying my PSU??

post #1 of 9
Thread Starter 
Hey there! smile.gif

I had a Corsair AX860 which died after a month, after a long wait I've finally gotten my replacement...

I have everything connected the same way as before but I've started wondering if I'm not putting too much load on the 24pin MB + 8pin CPU and a single molex modular cables.

I have 2x2000rpm PWM CPU fans, 4x2000rpm PWM fans and 1x1000rpm 3pin fans running off of MB fan headers putting load on the 24pin MB + 8pin CPU connectors.

On the single 4xMolex cable I have 2xSSDs + 1xHDD, 1x Bluray, 4x1000rpm 3pin fans and 2x30cm LED strips connected.


My system ran stable with no random shutdowns for a month before the PSU died, some of my fans sometimes didn't spin and some of their LEDs didn't light up at start-up but they started to act normal after the system was on for a short while, this is happening again after the replacement... One thing that I did notice with the second AX860 is that the steady ticking noise that was present in my system is now gone after the replacement...

Should I spread out the load over more modular cables or should the PSU be able to handle it in the present config meaning my 1st AX860 was just a bad individual unit?

My specs:
CPU: i5 2500K 3.3 Ghz (@stock/no OC)
CPU cooler: CoolerMaster V6GT (with 2x2000rpm PWM fans)
MBD: EVGA Z68 SLI
RAM: Corsair Vengeance 8GB (2x4GB) 1866 MHz DDR3
GPU: 2 x EVGA GeForce GTX 680 SC+ SLI (@stock/no OC)
PSU: Corsair AX860
SSD: Corsair Force 3 60GB & Kingston SSD NOW V+200 120GB
HDD: Samsung EcoGreen 5400 RPM 1.5TB
ODD: LITEON 12x Blu-ray

Yeah, you had a dud, the AX850 could handle that with no problems. RMA it.

I have already received and freshly installed the replacement from my RMA for the initial unit I purchased, just asking advice if connecting components in the configuration described above can put excessive stress on the some part or the whole PSU .

So I take it connecting many components to one modular cable doesn't really compromise some part of the PSU or the whole thing...??

You should be fine with that load. You just had a bad PSU previously, even the best models and brands have problems once in a while. Don't worry!

it's generally not a good idea to pull over 200watts from a single modular cable. HOWEVER, i doubt you are coming anywhere near that load unless you are doing something epically stupid biggrin.gif

Thanks for the replies, puts me more at ease... Especially now that I have others to lay some of the "blame" on if things go awry... biggrin.gif

I believe 4-pin Molex connectors are rated for a maixmum of 8-9 amps per pin, so you're fine there. OTOH sometimes the round sockets in those pins become loose after using them several times, and gently prying around them against the plastic body will tighten them up. BTW fans and motors typically draw just half their rated amps.

Properly manufactured MOLEX 4pin should be capable of around 10amps.

That said, I really think that you would be doing yourself a huge favor in purchasing a fan controller, or powering the fans off MOLEX while using a pair of splitters to get the motherboard control without pulling all the power from the board itself.

I am just far more comfortable having a lot of power going to the motherboard, but only to the components that actually require it. Fans, IMO, should not be powered from the board, they should just use the tach/PWM signals.
