I went to the asus website and they have a psu calculator and it said min psu recommendations is 700w.

I have a 620w Corsair (hx620).

I have 4 int hdds and 1 ext sata, 1 burner, 7 fans (8 with the heatsink fan), q9650 cpu, 4870 vid.

I think the 620 is good enough myself.

Opinions?
 
Does it work? then yes its fine. For how long, I dont know, but for now it works.
 
I would consider upgrading. Corsair makes great PSUs, but I would rather not take the chance.
 
the psu calculator calculates for everything in your system at a certain load.. so if you set it to the recommended 85%.. then your cpu is at 85% load your hdd's are at 85% memory 85%, gfx card at 85% all your fans running at 85%.. so yeah if that was true it probably would be under powered.. but the odds of actually putting that much load on a system is slim to none.. its just giving a recommendation if you were to actually run that type of load..

edit* i just checked your system on http://extreme.outervision.com/psucalculatorlite.jsp
and your wattage is:

Recommended PSU Wattage: *

obviously corsairs tweaked their stuff to use it as a sales ploy.. and of course all of them are based off the extreme power supply calculator i just linked..

btw i checked it with your entire system at 100% load including your cpu at 100% TDP..
 
I thought about getting a 850, But I think thats alittle overkill. Also I'd want a modular and aside from the 620, The only other modular corsair makes is the hx1000.
 
Your Corsair 620W is plenty of power for your system. Do not even consider upgrading unless you're just want to miss money away.

I dont see how you got 483 w,

I put in q9650, 100% tdp, 5 sata drives, 1 dvd-rw, 4 sticks of ram, single video, 7 standard 120mm fans and 1 led fan (cpu), fan controller, 1 usb device and 100 % system load and I get 776 w.

the fan controller has to be whats throwing the numbers off.. does the fan controller actually use a power source or is it just one of those manual nob ones for each fan?

btw you dont have to count the cpu fan.. thats counted in the 35w on the motherboard..

Actually Corsair's PSU Finder is not based on the extreme outervision calc at all. Are you talking about the Asus PSU calculator?

BTW fantomau, if you hit up the Corsair PSU finder, Corsair actually recommended the 450VX for your setup (Intel Quad Core OC'd less than 30%, 5 hard drives, and HD4870). So you're a-ok with that Corsair 620HX.
 
Sounds like you have enough power to me just check you amps draw from your video card which I am sure you are fine. I ran my gtx260 on an older 520w ocz powerstream adn I was underpowered and low on amps but it still worked just fine.

QFT. I don't see you needing more than 620W for your current system.

I agree, those power supply calculators are useless anyways.:rolleyes:

Keep what you have there it is a decent unit and spend your money elsewhere if your wallet is too full.
 
Yeah, I thought it was kinda f'ed up that I'd need a more powerful psu for what I got. Now if I had like 8-9 hdds and sli vids, I'm sure I'd need more.

I think the fan controller isnt as good as some of the others and I may get another one. Would the Scythe Kaze Master 2 be better than the zalman?


Thanx everyone.
 
Is there a better fan controller than the zalman I have? I was looking at the lamptron fan-atic, Says it'll do 60 watts per channel.
