I've got 3 hard drives in my computer and 4 assorted optical drives. I have a powersupply which can power 6 of these and a splitter so I can split one of the outputs of the PSU. I'm wondering if this will overload it; if so, what would be the adverse affects on my machine?

Specs:

Pentium 4 1.80ghz
512mb DDR
ATI Radeon 9200 128mb ddr
100gb HD
2x 160gb HD
2x CD Burners
2x DVD Burners

Additionally, does anyone know of a good website that may tell me how many watts I'll need if I choose to buy a new PSU?

Thanks in advance.

A DVD Burner will burn a and read a CD, so why does he need 4 devices with the same purpose. The 2 DVD burners will fit most peoples needs.

that is part of my point, if he is going to be doing something like burn 4 disks at once, it is going to put more strain on the power supply.

Yeah - I play in bands (bass guitar) and end up having to burn lots of demo discs, etc. Also, I can copy DVDs very efficiently with 2 DVD +/- RW drives.

Anyway, the one I was going to replace it with is only 250w. Don't know why it can power 6 devices; I was expecting about 350.

By the way - I took that test and it said I need 370 watts (I factored in another 50 watts for my other 2 optical drives; it only supports 2). This should be a major overload for my current 250w power supply. Why isn't anything failing? Am I missing something here?

Additionally, should I make sure I buy a PSU with a higher wattage then my recommended wattage from that test thing? Probably around 400-450?

Thanks in advance.

The values in that calculator are peak values. To hit that, every part of your computer would have to be maxed out. If you were burning 2 dvds, ripping 2 CDs, playing a high graphics game, recording some audio, defraging your hard drives, doing a memory test, and doing a CPU burn in... all at the same time, you might hit that max. For normal day to day use, I doubt it. If you really want to know, get an ammeter and measure how much current draw your computer is really pulling. I bet it is way under 250w when used day to day.
