So I've had this system a while (Gliese 581 d) I know they say you're not supposed to cheap out on your power supply and if you have 2 high end cards with a high end cpu then you should have a high end power supply and motherboard and so on and such and what not... well my pc performance isnt really what I think it should be, GPU usage is low, CPU usage is low, I get stuttering and stuff in games... do you think perhaps my power supply is to cheap or perhaps not enough wattage? I know it was enough wattage before but I've added some stuff and I know I must be cutting it close...

The PSU is not the problem, but rather, it must have something to do with the settings. Have you benched the cards with either Heaven 3.0/4.0. What were the results ?

For CPU, bech it with CineBench11.5 and post your results

The NZXT HALE82s are good PSUs, so you're ok. In fact, it's quite overkill for your system.

Do you have your 3770K's HyperThreading enabled? Having this enabled can sometimes cause gaming problems. Either that, or the NVIDIA driver is no good.

the GPU Usage is crazy, this was with CPU overclocked x40 and GPU's overclocked +111MHz/+209MHz

eeehhh not bad, while you have a ridonculous 25 amps on the 3 and 5 v rails you still have a respectable 53 amps on the 12v rail which is what you computer actually uses.

This explains what each rail powers (that is, the +3.3V, +5V, +12V, etc.):

Also, to figure out the wattage capacity of each, multiply the voltage by the wattage. So, +3.3V x 23A is 75.9W, +5V x 25A is 125W, and +12V x 53A is 636W. That means the 750W HALE82 is closer to being a 650W power supply, but it's still not a bad PSU.

636W on +12V sounds really wrong for a 750W power supply based on the new Seasonic M12II, which uses DC-DC for minor rails. Something's fishy...

Okay, I just checked, and it's actually 62A (744W) on +12V. newegg product page is the source of misinformation.

 

[cdoublejj]

yeah newegg has been having a [problem with that for a while now.

That a really low 3d mark11 graphics score. I get about 18,000 with 2 680's and about 15,000 cpu score with 3930k.

you should break 10,000 with one 680

keep in mind that was extreme, not performance but still get low scores on both settings

I used to get scores 10k+ on performance but recently this crap..... I have been talking to galaxy and I think i am getting them RMA'd!
