Shocking Kill-A-Watt results - Thoughts?

post #1 of 40
Thread Starter 
Hey guys, I just bought a kill-a-watt off newegg when they were on sale, and I was shocked when I saw how little power I was using. When fully loaded, my rig is only consuming around 350-380w, and that is with it overclocked.

I just thought I would ask, does this mean that my rig could possibly handle another gtx 580 in the future? Or would that be too much for my psu?

Thanks!

With the PSU you have, absolutely.

People overrate how much power they pull all the time. You need to be realistic with yourself


Also, try LinX + EVGA OC Scanner, it will pull more power as that is 100% load. I noticed my rig pulls only 600-800W while gaming but if I load up LinX+some GPU burn test, I get 1,050 W drawn from the wall

the wattage you draw from the wall is not really connected to how much you can safely pull from your psu. I would recommend 850w for 580 sli, with a bare minimum of 750 quality watts.

It's hardly shocking, everyone seems to buy up a much more powerful PSU than they actually need.

As for whether you could go 580 SLI on that PSU? I'd personally be a bit wary, my VX-550 could theoretically have taken two HD4890s in CFX, but it blew up after a month or so of having that, it's mostly about the +12v rail and how many amps you use on it.

how do you mean fully loaded? Playing a game? or running prime95 and furmark extreme at the same time?

But yes, power requirements are usually overstated by a ton due to all the crappy psu's with bogus wattage claims

This is while folding both my cpu + gpu, which is the most intensive thing I will ever do on my rig. Prime 95 + furmark is unrealistic power draw.

Talk about overkill. Absolutely unnecessary.

I just bought my Kill-A-Watt today too. I'm surprised. Both GPU's folding get it to around 360w. Gaming is around 360w as well for me and right now I'm at 170w. My mom is getting mad though as she thinks its costing about 40$ a month. Idk how that can be right.

Kill-a-Watt can read up to 15% low on PSUs with active PFC. Has to do with how it reads current.

However, even so, your system draws far less than most people think. You *could* run another GTX580 on your PSU, though I usually recommend a 750W for SLI GTX580s.
post #10 of 40
It's a Seasonic X650, so I wouldn't be afraid of treating it rough. Another GTX 580 would be too much for a true (synthetic benchmarks stress tests) full load, but it's probably okay for folding. 750W or perhaps even up to 850W (for total overkill even for really high overclocks--750W is more like it with a i5-2500k) would be a better idea if you were starting from scratch, but the X650 should work.
