Reply: (edit)New systems like yours usually need a good PSU with a higer wattage. I recommend 400 Watts +. Also, if your PSU fails on you it *could* take some components with you. You wouldn't want that, do you? I used the PSW @ http://www.jscustompcs.com/power_supply/ and came out with a recommendation of 271 Watts.

Reply: (edit)You need to check out the individual current spec for the PSU - you will often find that a 400w PSU handles less current on the 12v rail than a 350w. My advice is to go for a reputable branded PSU - my favoured is Antec - and expect to pay at least £50 for a fully protected PSU that will provide you with solid service over a long time. People don't realise that the PSU is equally as important, if not more so, than any other major component in a PC. "I know that I'm mad - I've always been mad..."

Reply: (edit)yeah, a 350W probably would cope I ran an Athlon 2800, 2 CD ROM drives, 2 hard drives, GeForce FX 5900 Ultra, soundcard, modem, etc etc on a 250W supply for over a year with no problems at all. But, to be on the safe side, you might as well get the 400. It also means you are future-proofing your system, at least in terms of power requirements.

Reply: (edit)no no no!!! you people are all wrong!!!
except for johnr in the 3rd post-you're on the right track look at the amps on the +12v rail you want at least 18amps, more is better! you people are all just looking at the wattage, this is bad
you must look at the amps on the +12v rail, then the name brand, then the wattage rating a word of advice
you cant trust ratings on powersupplies these days since they are not tested
so often times cheap psus will have generous ratings only to fail and miserably kill everything in your system long before their warranty says they will
this is why you buy trusted name brands-Antec, Enermax, PC Power and Cooling
and someone around this forum seems to really like a certain thermaltake psu at newegg.com for $40 ;)
it is pretty good too what is painfully obvious to one person might be just painful to the other

Reply: (edit)from pc power an cooling about choosing a supply For overall power supply wattage, add the requirement for each device in your system, then multiply by 1.8. (The multiplier takes into account that today’s systems draw disproportionally on the +12V output. Furthermore, power supplies are more efficient and reliable when loaded to 30% - 70% of maximum capacity.)

Reply: (edit)Thank you all guys... giggles you make a point...I 'll see the amps at 12v rail to chose my PSU cause many manufacturers (noname) sell 550W+ for 30 euros here in Greece and for example Antec sells that at 150 euros...It's obvious that something goes wrong...
