as the title says can my powersupply handle more?

at the moment this is my rig: AMD 1100t 3.3ghz 6cores ( non overclocked )
GIGABYTE ATI RADEON 7870
8gb RAM
x1 1TB HDD
FRONT BLUE LED 120mm fan
SIDE BLUE LED 120mm fan
REAR non LED 120mm fan
top non LED 140mm fan.
OCZ fatality 550w powersupply.


If im missing any information please ask for it...

All that is my current computers specs. Im thinking of adding NZXT sleeved BLUE LED KIT 2m and a Solid state drive, preferably the corsair 120gb one. Can my powersupply handle it?

HD7870 draws at peak 115W. At full load 1100T system with one HDD is around 210W. There's plenty of room left.

It's easy, that's why TPU reviews are:



My main PC draws 380-400W from the socket under heavy load, I have 6 HDDs and the 2500K is at 4.2, the GTX570 uses up to 180 -190W.

The SSD will draw around 6W peak. LEDs won't ask for much more either. And you have enough power headroom to add another HD7870 if you wish, provided you keep everything at stock or slight (up to 10%) OC.

Says who and based on what?

What do you think the efficiency rating is for? A 80% efficiency rated PSU, is most efficient at 80% load, which is why you don't want to max out it's power rating. Atleast that's the way I understand it from the knowledge I've gotten from the people on this site.


even a system as beastly as mine draws about 560w tops. I got a power monitor and played some BF3 while watching my power draw on the display

And by those numbers, a 750-800 watt PSU would be running at around a 80% load, hence why I said nothing less than a 750 watt PSU for crossfire or SLI. I'm not saying crossfire or SLI wouldn't run on a 550 watt PSU, but IMHO, you'd be stressing the PSU too much, and we all know what can happen when a PSU goes.

depends if the OP wants to crossfire. For single monitor use where the monitor is 20-24", dual GPUs seem like a waste of money... I know im one to talk as I have 6970s in crossfire and one 23" monitor but my thinking has matured since then :p

Unless the OP buys a 27" dell/catlap/newcrossover screen etc etc theres no real reason to go dual GPU unless for epeen

While I agree with your take on whether or not SLI or crossfire is needed, that's not what I'm advising against. McSteel suggested the OP was fine to add a second 7870 and that the OP's OCZ 550 watt PSU could handle it without issue. Personally, I feel that while the PSU may be able to handle it for some time, it would be over-stressing the PSU and would eventually cause the PSU to fail prematurely, possibly killing other components of the OP's computer. 550 watt PSU's are not strong enough to safely handle most crossfire or SLI configurations IMHO.

I'm not saying crossfire or SLI wouldn't run on a 550 watt PSU, but IMHO, you'd be stressing the PSU too much, and we all know what can happen when a PSU goes.

At what load it's the most effieciant is of no importance unless you're running it 24/7. And how much power you draw changes constantly, and remember no PSU is great at 10% load, which if you have a 750W PSU is what your avarage system will use when idling. By this logic you shouldn't have the computer idling becuase it is less effecient then.

And the PSU's are rated for what they are rated for. For normal use you can push it to 100% as much as you want, and the reputable PSU's will probably do more than 100%, but that is not something I would recommend as it is not guaranteed.

It should be said you should plan ahead when buying PSU's. Don't just look at what you'll use right now, where will you be in a year? But that "not pushing them above 80%" is bollock (unless you're folding or something like that).


BTW, about 7870 in crossfire: I'd say it depends on the model. Some cards go way way above others during Furmark (which isn't realistic but still), while others don't. Also depends on the OC of course, but if you're running a stock card with no plans to overclock you're fine with 550W.

:laugh::laugh::laugh::laugh::laugh::laugh:

No mate, it doesn't mean that at all, it means that a PSU needs to be more than 80% efficient during several different loads ranging from 20% load all the way to 100% load.
http://en.wikipedia.org/wiki/80_Plus

Admittedly maxing out your CPU might not be ideal, but 90-95% load is not a problem.

90-95% load is not always good on a PSU IMO. OP, You could pick up a watt o meter to check the draw. They are cheap.

I wouldn't be too sure about adding a second 7870 with only 550 watts. Remember, your suppose to try to not load your PSU much more than 80% load. 750 watts is the least I would use for a SLI or crossfire config, unless running something like dual 7750 cards.

my 3770K and dual 7950's at stock use 398W.

OC, that becomes 700W. DrDeathx even tried himself with his cards when I mentioned this some time ago, and get similar numbers.

My 3960x and dual 7950's pull 500W, 800W when OC'd.


At stock, 550W PSU should be OK, but yes, as soon as you OC, that PSU may say "NO WAY!!", and will definitely limit clocking ability of either the CPU or VGAs.

It's about one 7870 and 1100T, even if he attempts reasonable OC, which wasn't the question here, a 550W should do fine.

Sometimes its worth checking what the terms mean: http://en.wikipedia.org/wiki/80_Plus

Be careful, an overclocked 1100T can easily draw 200+w under stress. That said, the PSU will run all the listed components fine, and if it doesn't OCP/ other protection will kick in.
