Can a 430W PSU handle it?

I measure my system draw which has several drives, water cooled, overclocked i7 2700k and Gigabyte WF 670. I pull 330w from the mains with prime and Furmark running together.

So you are trying to say your system uses 264w?

And it doesnt matter if you run them both together, either they both use 50% performance, or one uses 100%.
 
He probably means 330w DC, which honestly sounds about right for a 2700k/GTX 670 overclocked. I'm running an OC'd i7 860/5870, both of which consume more power than his rig when you factor in overclocking, and I draw around 350w DC under Prime/Furmark and between 250-300w gaming.

Running Prime/Furmark together isn't going to use 50% performance, I don't know where you got that idea.

I know, but check my CPU, I have overclocked it and am subject to intense power draw..


I know it over estimates, but still.

By a HUGE amount. Most of time more than double.

you'll be fine with a decent brand 430w.

I recently got a 380w seasonic psu for a secondary system that happily powers a heavily overclocked old core-2-duo dual core cpu at >1.5vcore, hd4850 and water cooling system just fine.

What I mean is each program will use a portion of his PC's performance. The way he put it was as if by running both it stresses the system more.

Basically;
Prime95: 50% of resources
Furmark: 50% of resources

Total: 100% resources

Compared to:
Prime95: 100% of resources
or
Furmark: 100% of resources.

The way he made it sound was as if he would be drawing more power running both, which is untrue as both programs can max the system out alone, so by running both it doesn't push the system further, they both just run with half the resources.

Sorry for over complicating things

It would probably be like that if he were running Prime95 and LinX/IBT at the same time, as they're both stressing the CPU... but running Furmark (for example) alone is not going to be using 100% of resources.... the CPU is still idle (or very close to idle). You will be drawing more power running both.

You're not over-complicating things. You're wrong. The processor and graphics card are almost independent. It's very much possible to redline either while the other is idle.

430W will be fine for that computer. My power measurements are a little out of date, but at idle a 4ghz i7 920 + 2x overclocked 8800GT uses 160W. Under full load, both gpus and the cpu, it was 373W.

So the Corsair proposed would run my ridiculously power inefficient system quite happily. I'm certain it will handle the OP's spec with no issues.
 
When i had my i7 920 at 4ghz and sli gtx 470's, oc'd at 750mhz on core, power draw at the wall was.

Idle, 190w
Gaming, 630w
Prime95, 440w
Furmark, 740w
Furmark + prime simultaneously, 860w when i stopped the tests. Psu was a corsair HX850w.

If I remember correctly (I need to double check) I pull more running both rather both individually.
 
Okay so I appreciate all your replies and I think I'll just wack it in my system since it arrived a few hours ago.

I had 2 120mm fans, Arctic pro freezer 7 CPU heatsink, 1 500GB SATA HDD and a 64GB SSD

Does that change anything? D:

860w is perfectly fine and safe. As 860w from the wall transferred through a 80% efficient power supply equals 688w, well in the grounds for that PSU :)

Just so people know, the efficiency is how well it converts AC to DC, so 125w AC from the wall equals a total system draw of 100w DC on the PSU with a 80% efficient PSU. Meaning that system would be powered fine by a 125w PSU with a little headroom. PSU wattage is measured in DC, the draw from the wall in AC.
