High voltage input question?

Power supply question?

  • My pc Specs: DELL Optiplex 755 Win 7 (32- bit) Intel core 2 Duo 2.66ghz 3GB RAM DDR2 Please answer my question: 1.Well i am asking is all power supply different?... Because when i first heard of RAM i thought there were the same but it turns out they are 6 different RAMS(3 Desktops and 3 Laptops). 2.Will this power supply be compatible with my pc?

Are all power supply compatible with all PC's or there all for individual pc's? Please answer :D

  • Answer:

    Most ATX power supplies for PCs are compatible. 750w are just more powerful than the 500w I have, it will work the same. I copy the following checklist from lifetime warranty topmic charger website You might notice different ATX power supplies have different watts, but their voltage outputs are similar (watts=voltage x amp) 1) Output Voltage is within +/- 5% of your old power supply's output. For example, if your old power supply provides 19.5V, then you can use a power supply that provides 20.5V or 18.5V. 2) Output Current is the same or higher than that of your old power supply. For example, if your original power supply provides 3.42 Amps, then you can use a power supply that provides 3.42 Amps, 3.9 Amps or higher.

You can bet any modern power supply will work with any modern computer. However, some older computers (and perhaps newer computers; I'm not sure) make it so you can't replace the power supply. You'll definitely want to check that first (make sure you can disconnect all the wires coming from the power supply). Then there's the fact that if your PC is slim/Micro-ATX or smaller, the power supply probably won't even fit in the case. But if it's a normal, mid-tower computer, it'll work fine.

there is one main physical size of power supply [ATX form factor] and a couple of lesser used smaller ones for things like small footprint desktops, etc. All mid tower and full tower desktops use this ATX size. however, they come in a bewildering variety of power outputs, usually expressed as wattages. the one you're pointing at is a 750w unit ... and may well be much more, in size and cost, than you need. newegg.com [US site] has a psu sizer app on the lower left side of their power suppliers page. you just put in the details of the computer you want it to power and it figures out the minimum wattage required. i add 10% if I'm planning to overclock. if you're planning to add a second graphics card, you add for that, too.
