Hey there :-)

My main issue with psu's, is the huge varience in what people say you need. I just viewed a thread on another site, where the experts were saying a guys 550watt psu wasnt enough, and he needed to step it up to 750 watts!

I find this interesting as i have a corsair hx650w running a readeon 6870. Tell me, is the radeon 4850 way more power hungry or something?...Cos this thread scares me as i thought i was MEGA safe. (the guys cpu was a wee 2.8ghz..idk how many cores but nothing huge?

Thanks heaps everyone :)
 
I don't know what expert said that but it's completely false. A quality 550 Watt power supply would easily handle a 4850.
 
Depends on the unit. If it's some shoddy el cheapo that's rated at its peak output rather than what it can sustain, yes, you may need to go that high, but you don't need that many watts if you get a proper PSU.
 
I this particular instance, the "experts" weren't, a decent 650W is plenty enough for a 6870 or a 4850, which your HX650 is, heck 500W would be, even if you were sat there with a high end CPU and a couple of hard drives on top of the card
 
Thanks. I mean the guy was at 550 watts coz of the cost. to say he needs a 750 is not very nice for him to hear. The thread was closed as solved with the conclusion being he needs a 750 watt. Poor guy
 
Nah he just had to pay for a higher quality power supply. I have a 700W OCZ in my old computer and it handled an Athlon X2, three hard drives, and a 4870 no problem.
 
A lot of people over estimate as well and rate psu's on what the sticker says. I'm fairly certain my Thermaltake Litepower 600w is not better than my current psu...
