PSU Calculator

[aidanjt]

Its a lot more accurate than most peoples misconceptions of computer power requirements.

However power usage is rated in Watts, thats why your meter counts in kWh.. Maximum amperate is important for powering devices from your rails, but again thats PSU efficency playing into effect again.. But generally speaking 12v rails on all quality PSUs would be very difficult to max out without being a total numpty.

Quality is all that's important. Often a quality PSU will be a branded one with x00 Watts, but you are paying for the quality, not the extra wattage.

My Macron 300w with a knackered fan was stable on my machine where my 450w Qtec wasnt, not quite sure what your getting at

Exactly that. 300W is enough for anyone, but buy a crappy PSU and it won't be.

at 80% mine is 368W
at Peak mine is....404W...

my PSU- Hiper Triple Fan 525W [Peak power at 570W]
hmmm i wonder how much i can push me 754 A64 3000+ ?

I bought my s12-500w mainly for it's quietness and efficiency. I know it's more power than I need but the 430w model had no pci-e power connectors and I knew I would be using most of the molex connectors. Therefore I didn't fancy an adapter to power my x800xt.

Also if i do any upgrades that need more power the psu will be able to take the strain without problems and not generate excessive electricity bills through inefficiency. Wish I'd waited a bit before buying it though, at the time of my purchase there was only one place in the uk that sold them because they were brand new and seasonic had no real presence in the uk market.

I hope that wrong

Says my current system is 473w (current PSU 400W and everything is rock stable) and when I place my 2nd 7800GT in tomorrow it will jump to 563W!!!

Nvidia recommends a 500W PSU as a minimum for SLI for a reason you know.

Not quite as up to date as the one posted sadly.

The only thing is, I used to move a lot less stuff with a 370W PSU (Not no-name brand but I wouldn't say it is too high up the list) and I lost one HDD every month until I realize the PSU was crap. Even if it say it only require 267W and my old 370W couldn't push it properly!!

mabee it wasnt the lack of power, i could be in a bad powersupply that it had huge fluctuations that the hard drive couldnt handle, whatever just seems good to get a good psu, a mate of mine had a generic one of his explode a few weeks ago, sparks and smoke everywhere apparantly, although the rest of the pc lived

Well, my 'supposedly' 563W (at 80% load) system is now running perfectly fine on a 480W Tagan......

The numbers on that calculator are quite inflated IMO......they have added around 20% or more to the requirements......guess they wanted to quote on the 'safe side'....

Useful but it isn't accurate and its a bit misleading because they dont explain that it isn't total PSU wattage isn't whats important - its amps per rail, particularly the +12v rail that likely to be critical factor.

Still, anything to sell you a overpriced PSU that you don't need.

It's not misleading. Please have a closer look again

"ATTENTION:
The total Watts is important but the Total Amperage Available on the +12V Rail(s) is the most important, followed by the +5V amperage and then the +3.3V amperage. Because of the increased power consumption of the new high-power video cards the recommended minimum for +12V is 24A."

Oh my God, this is so crazy ! 389w.
