Peaking out my PSU??? Help

post #1 of 12
Thread Starter 
So I know the TR2 RX 850W (single rail@69amp) isn't the greatest PSU, but Thermaltake does rate it 80 PLUS BRONZE Certified.

Well my system was stable for the past week at 4.23Ghz1.5v NB 3.0Ghz 1.45v, but recently my system has be restarting once in a while.

I need help figuring out if I'm maxing out my PSU.

I have an 8800GTX oc'ed to 600/1600 (core/shader) (320W)
GTS450 oc'ed 937/1870(core/shader) (230W)
And the CPU oc'ed sig rig(190W)

From just those 3 components I'm calculating ~750w of power draw, now I also have my water loop(XSPC 750 RASA360 kit) 2 WD Greens, SSD, and DVD-RW.

And my case is at ~48C which would most likely make the PSU run less efficient.

Am I calculating this right? Do I need a better PSU?

You should only draw that much power if you are running something like prime95 and furmark at the same time. It might be a PSU problem but I doubt you are actually drawing 750w of power.

I fold 24/7.. I was under the impression that while folding the GPU and CPU is under 100% load which would draw much more power than idle.

Folding pulls about 3/4ths the power of LinX+Furmark.

The TR2 RX 850W is overrated and cannot do 850W continuous.

You need a better PSU, but not a higher wattage one. A quality 650W would do the job with ample room to spare.

Any recommendations for a system that runs nearly 50C 24/7?

My budget is lowest as you can get for a quality PSU that will support what I have.

If 650W will really be plenty, then I'd go with that.

I know lowest and quality really don't go together but if I can get a 650W quality PSU for under $100, that would be the winner.

Without actually doing ALOT of research, that's my first suggestion, if you don't mind the MIR

Couldn't find a review on that specific model, at least not from a reputable source, but did find that JonnyGuru.com rated the XFX model listed below a 9/10

http://www.newegg.com/Product/Produc...-009-_-Product

Personally, I don't care for the looks of the XFX, but I don't know if the value can be beat!

The Silverstone OP800 apparently is as good as the XFX model, but a tad bit more...

I think I'd rather have the Silverstone, merely personal preference

The XFX seems to be the best choice for me (62AMP at 50C). Thanks rsfkevski
