No, for the slim tower Dell Vostro 200, you will need a specified PATX psu. Only the mini tower can accommodate mATX-ATX psu's.
All ATX-standard computer cases are compatible with all ATX-standard power supply units. Another issue is the selection of a PSU suitable for your computer components - what is the current consumption of your computer?
Yes any normal psu will work in your compaq 5330. By normal, i mean a standard ATX psu. Rather than the elongated one's.Hope this helpsbe safe
The older format, AT, will power up without a motherboard. ATX form factor needs motherboard connection to power up. However, for about $15 you can purchase a PSU tester that plugs onto the psu to allow it to power up without the motherboard. Try: dalco.com, or FRY's etc. Actually, ATX will start without a motherboard, or a 'PSU tester'. The ATX motherboard power connector will have 1 green wire, and several wires of other colours. Find a bit of lose wire, it doesnt need to be very long. Make sure both ends of the wire are stripped. Push one end of the lose wire into the 'hole' that the green wire connects to, then push the other end into any 'hole' that has a black wire leading to it . The PSU should start, and stop when you remove the lose wire. == ==
Pretty much any power supply (aka PSU) will be fine. As long as it has between 500 and 1000 watts and is ATX compatible.
Micro-ATX
You need a power supply the M2-ATX 160W Intelligent DC-DC PSU is designed for this purpose.Once you lick that you're doing the same stuff you do at home.
The ATX power supply uses 3.3, +5, -5, +12 and -12 volts, plus a common or ground. The +12 and -12 are used by one pin each, so I would guess that would be what you mean by the seldom used. The 3.3 volt is what distinguishes the ATX from earlier power supplies, which only had +5, -5, +12 and -12, plus a common or ground.
There are not really any advantages with a ATX over a Micro ATX just Micro ATX is smaller and ATX is larger
An ATX power supply unit delivers power in three voltages: 3.3 volts, 5 volts, and 12 volts. The 3.3 volt pins are used only in the motherboard connector. Older, AT power supplies and motherboards used only 5 volt and 12 volt pins in the motherboard connection.
