but the new one is a 300watt, will that cause any damage or malfunctions, or over heating. Or will it be ok to use??

If the old one was 350 then a 300 will probably be ok. The size of power supply you need depends on how much power your system will use. A Pentium 4 uses more power than a Pentium III. Also if you use just 1 hard drive and 1 cd drive, that uses less power than if you use 2 hard drives and 2 cd drives. Also if you have any add on cards (like a modem, high end sound or graphics cards) they will also use more power.
But if you were using a 350 and haven't added anything else then a 300 will probably be ok. HOWEVER, I never put anything less than a 450W in systems just to be on the safe side.

Hard to say if this will cause him problems or not. It depends on what components are in the computer and how power hungry they are. As a general rule though its a much better idea to go bigger when replacing a power supply. If it is being over-taxed it might not fail outright but start some weird behaviour such as random reboots. Shouldn't cause any overheating or damage to the computer though.

Ive blown up a 350w PSU through fitting a new graphics card. Ive just had to upgrade to a 650w because of my new graphics card!
There are websites which can calculate your power requirements, you select CPU etc from drop down lists - do a search (ive forgotten the address)
And all PSU's are NOT the same. A cheapo 400w is nowhere near as good as a make like ANTEC, the voltage on each of the PSU rails can vary.

When replacing power supply should always fit at least the same wattage, or best to play safe and go higher. As you don't say what computer make/modle is, what has been installed, any extra parts/upgrades, it is difficult to say for sure, but would not recommend installing lower powered supply

The power supply that came in the tower is based on the amount of components you can add on (hard drives, pci cards, fans...etc.) If the majority of available slots are unused, you (he)should be fine.

It shouldn't so long as the power draw on the unit isn't very high. 300W is not very much for modern computers but would be sufficient for a PC with older components and fewer drives.

no longer likely. given which you had further aspects to it, might have decreased the existence expectancy of a inventory power grant. I truly have diverse old desktops, which consists of a homestead windows 3.a million, by no skill had issues. in simple terms as quickly as I flicked the curious finding purple activate the lower back did i by hazard blow one up.

You do not want to replace a power supply with one with less power. It may be that you will not be able to power your devices adequately and you may end up harming your system.
Always opt for the same wattage or more.

It should be fine if he doesn't have a super high-end video card or multiple hard drives. Also helps if he uses either an older AMD processor or a newer intel one (core 2 duo).

it will be fine, no problems at all. they go up to 450 watt and beyond. as long as the board needs it everything will be cool. and all boards benefit from more power anyway.
