300w powersupply on X850XT? imposible!

on the box of the x850xt it says requirement 350w psu. i pull out the x850xt from an old machine that has 350w and install on a new machine and i didnt even thought of how much watt is the psu on this machine. it works. after few months realized that i never knew about how much psu watt it has so i finally open it up and check the psu. it says 300w.

300w on x850xt???? that is unbelievable! but it works flawlessly... no blue screen no nothing. how can that be?

so is this mean i can install 8600GTS/8800GT/9600GSO as well?

how much really the x850xt draws power anyway?
 
thanks thats a good site i never been there but wow it ask many stuff and some of the stuff i left it blank since i dont know. as i hit the calculate it says recommend 351w

the 300w psu is stock in acer m5100 desktop. it doesnt says brand name.. just says fsp group something like that.
 
try and run something graphically intensive like crysis, on max, so that you get really bad framerates, that should put quite a load, that might cause it to shut down
 
At one point or another that PSU is going to give out, and it is not going to be pretty. Not only is it a 300W when you need AT LEAST a 350W but than you have to take into account the efficiency, which lets say is 80% (which is very good) which would take you down to 240W of true power. Get a new power supply.
 
the power supply calculator is not to be taken seriously. on my rig with my fans and such said i need a 1012watt PSU. im running everything off 600 watts no problem.

majority systems will run beautiful off 750w PSU with 80% eff rating or up.
 
that PSU is probably running at 100% all the time, maybe even tryna put out more than it can handle.

not a good idea.

and its bad for the rest of your components in your system...
 
These kind of anectodtes mean little and only serve to convince those who come to this forum looking for confirmation of their false belief that a low powered POS PSU will run gear fine outside recommended 12V rail specificaitons. Its bullshit. Yes it might 'run', even for a few months. A good analogy is engine oil. You can 'run' a car without engine oil in cold climates for a few months, yes, it will run (i have had this happen to me in the military), but without doubt eventually the engine would seize. If you are happy for your computer components to **** out, then by all means follow this anecdote.

What they don't say though is when it all goes pear shaped. That is, you only hear about the guys risking their gear 'claiming' everything is ok - not the guys who just destroyed $500 worth of motherboard, ram etc and a corrupt Windows install. Oh and then a new PSU anyway.

Its stupid and proves nothing. Electronic gear (particularly consumer gear) is pretty good at working, even outside of rail specs. Run 3DMark06 and Prime together for a day. Then come back and be honest.

My thoughts exactly.

Also, the PSU calculator I provided should not be the end all, be all when it comes to wattage use. It's simply a foundation from which to start from. For all of my components it says that I need around a 480w PSU. Yea like I'm going to run my 9800GTXs in SLI and 125w Windsor CPU on only 480 watts! I could probably get away with a 600w PSU, but instead I went for the 750w to give me some wriggle room.

Look, like bigfella said, can it run? Sure. Is it smart to run it like that all the time? Absolutely not! Eventually you're going to blow out the entire system and be left with a garbage bin full of parts, including that video card. The car oil analogy is perfect in this situation...
 
ok i might concider buying a new psu then. but it is tempting to leave it and see how long it will go wrong. its been over 5 months already.
 
I use this as my power draw ratings.
" It is supposivly the REAL power draws from video cards..."

So by this the max draw fro the 850, is 69watts.

So i figure you should be fine, not recommened as you can see by the other posts, but if it has run for 5 months, then keep it in, just be ready if it goes out, Hopefully if you are lucky, it won;t take your whole system with the psu:D
