Can I use 2 power supplies on one board?

post #1 of 9
Thread Starter 
I am trying to attain high clocks on my old celeron d 326 with air cooling. i currently have it clocked at 4.75Ghz on my abit ix38 motherboard with air cooling. I want to go for 5Ghz, but BIOS says my cpu is drawing 91amps on my 70 amp PSU. i want to use the current PSU in ths rig to power the 24pin and periperals and use the 850w PSU in my main rig to power the 8pin cpu. my 850w psu has a second 8pin connector. can i just plug this extra connector into the ix38 and run both of the rigs at the same time? or are there any other ways i could get more power to my motherboard.

I am pretty sure that means it is drawing 91A x CPu voltage = cpu watts. Not 12v amps or watts. if it was 91A x 12v that would be 1091W !! But say your cpu is at 1.5V that would mean 91A x 1.5V = 136.5W. So you don't need to.

Unnecessary. Don't bother.

my vccore is at around 1.76 and would probably go to around 1.8 if i reached 5Ghz. would my mobo be able to supply this much power?

In pretty sure the CPU will have something to say about those volts, before you even run into power issues.

yeah, you need to go colder, under air I think your at the limit, or close to it. Power is not an issue.

You're not going to get higher without water, DICE, or LN2.

Celerons and Celeron Ds overclock like bosses under LN2. Suicide runs with voltage up to 1.8V. I think the highest clockspeed records are all held by Pentium 4 Celerons, up to 8GHz+. Netburst was always made to run at high clockspeeds, and the Celeron versions were always chopped down to the bare minimum, so can attain higher clockspeeds with less heat and voltage.

at 5ghz a 2600K at 1.5v will consume about 150watts not considering the efficiency of a 24 phase power supply on the motherboard (~85-90% at something like 300khz switching frequency) Mine did at least and I have a meter that is hooked up to the 8 pin connector on the motherboard, it tells me the current and wattage pull from motherboard to the CPu power plane. its a nifty little thing. I just bought it for my reviews, zalman makes em they are 50 bucks. The CPus at stock especially pull much lower wattage than you would expect.
