Idle 175 Watts...Load 550 Watt... 750 Watt PSU?

post #1 of 17
Thread Starter 
I have a Corsair TX750 V2 PSU (750Watt).

I have the Zalman ZM-MFC3 Fan Controller which has Power Consumption Monitor.

It shows me that at idle the system runs at 175Watt and at Load it runs at 550Watt.

Is this a little too close for comfort with the 750Watt PSU?

I was hoping to upgrade GPU's later as well. Will I have to upgrade PSU with them?

Any suggestions are appreciated

200w isnt close at all.... your psu is fine. Also i would bet the farm that rig doesnt come close to using 550w. probably closer to 300w at load IF THAT.

When playing BF3 and MW3 it definitely goes over 500Watt.

Keep in mind that I have CPU overclocked to 4.6GHz and GPu's overclocked as well. I also have several high end fans in the case too.

Nah I doubt so tbh, if you are using a 560ti/6950, it'll use over 500W, but a overclocked 8120 and a 6790? It is nothing for a 750W. Get a 550W.

I ran a power hungry i7960 and a GTX 580 overclocked to 960Mhz on a 650W No way your rig needs 750W. PCs use less power than you think.

Unless you are using Delta High RPM fans, the fans probably wun affect anything. My HAF-X has 4 200mm NZXT fans, 3 120mm fans, 1 140m fans.

Ok, I was about to say there is no way you are drawing that much power.. Then I saw you have a BD x8. You have to factor in efficiency too though, 550w divided by ~83% = ~457w

You have ALOT of headroom, Still.

I'm considering getting that controller but I too wonder and hope it's accurate on wattage draw.

200w isn't enough extra room for you?

is this before or after AC->DC conversion?

You're fine, keep at her the way she is.

200w is plenty and I bet your system isn't really using that much either. thumb.gif

Unless I'm missing something, a 600w would be fine at full load..
