Enermax Galaxy 1000 Watt PSU
Fascinating read, I will get this one, good brand and resonable price.
Wow, very mad indeed. Apart from multiple server PSU's - thats the highest wattage single PSU i've seen for a desktop computer. Computers are just getting thirstier and thirstier for power... cleaner cars, dirtier computers 🙄
I bet it will be small in 5 years.
The new video cards are power hungry, they are up to a gig each now, what will the future be.
My first card 11 years ago was 2½mb in a P-166. That machine still works, with 98X over 95X.
that's f***ng mad! I have 500W now with 256mb gfx and I need it in 60-70% only. Imagine the elec.bills. Honestly, your water heater has 2000W and eats elect. like crazy. Imagine this for 12-14h daily with 1000W. this is sick, really.
Surely a 1000Wts at 12Vts output, does not use the same Wattage input, at mains voltage!
Uhhh, folks....Just because a power supply is rated to handle higher wattage, doesn't mean it uses more power if the computer isn't drawing it.
One big advantage I can think of is that if you only use 1/3 of its rated power, it will run very cool.
I will be getting it, as well.

Actually, because a PSU is not 100% efficient, it requires slightly more power than it produces.
This is a little simplistic but 120 volts at 1 amp is 120 watts. 12 volts at 10 amps is 120 watts. Google "Ohm's law", for a more detailed explanation.
But, because of its inefficiency some of the power the PSU uses is converted to heat, etc. Therefore to produce 12 volts at 10 amps requires 120 volts at more than 1 amp.
Yes I know that PSUs are not 100% efficient, but I have been under the impression that say 1000Wts at 12VT, was only something like 50Wts on our 250Vt mains. Wish you hadn't told me now CG, cause I now know why our Electric Bill seems to get higher each month. Shall have to cut down on my 12 hours computer time a day. 😂 😂
I realize that I goofed by referring to Ohm's law which is deals with resistance in a circuit, not computing watts from volts and amps.

That's OK CG, I won't tell anyone.....
More info on PSU input/output. Found one of my friends is an electrician, he said if the voltage output is lower than input, then input amps are less than output. Said the mathematics are complex, over the top of my head. But to prove his point he brought a consumption meter, fixed it between our mains supply and my 580 Wt PSU and I fired up my computer. Left it connected, so it would show maximum wattage reached during period of use, and after 30 minutes the max Wts were = 190 (One Hundred and Ninety Watts.) Bear in mind, this is 190Wts of mains supply power. He then said my PSU was not very efficient as it should have been less, around 120Wts. But that is the one criticism of the Hiper PSU range, poor efficiency, output is OK, but higher loss than many other PSUs.
I asked about having a 1000Wt output, he said without knowing many details, a rough calculation should be around 400Wt consumption, apparently the efficiency lowers as the output goes up.
The only proof I have, was visual, the readout on his digital power meter thingy!
Hopefully, I may be able to borrow this meter over the next weekend, while he has no need for it. I'm interested in connecting all my peripherals also, to get the over all consumption of the complete set up.
Just before removing the meter, he changed the reading to Amps, which were = .56 (decimal point five six), and mains Vts were = 229 @ 50/c
There you are CG, I can't explain how or why, just that these are the readings from some pro electronic meter.
Just remembered, when off-line, make sure your mains supply to computer is switched off, else there is still a current drain of around .1 amp. And I was guilty of this, I'd let my computer switch off via software, and then leave it. So my power consumption has been increased by leaving the mains on. Seems if the PSU is receiving a supply, even without any loading, it is still eating electricity.
Are there any APUs for computers out there? 🙄

How about a 30kw auxilary power supply for your computer
