I am about to replace my computers basic chassis with a new gaming case. It is a Emachine t6414, and uses a 300w power supply. The case I have bought comes with a 450w power supply, but there are rumors that it dies a lot. If I install the new power supply can it potentially destroy the computer and make it unusable? Should I use the old 300w supply, use the free 450w or buy a new 400w that is garenteed to work? Thanks.

yeah there is always that potential but the reason you need a bigger power supply is if you are running higher end video/sound cards or if you run a lot of peripheral devices like printers, scanners, external hd's, usb devices. i run a 450w. in my desktop cuz i run alot of peripherals. it runs it fine, just make sure you wire it properly. it isnt going to put a surge of power into your pc shorting things out if thats what your wondering. its just made to supply more power to more devices, thats all.

Look at the label on the new PSU and see what amps it has on its +12V rails. Probably wont be enough to run a big video card. Some 430watt PSUs have 18 amp rails other 430watters have 30amp rails. One can run an 8800 video card the other cant but they both have 430 watts. "Gaming" cases usually come with a window, an LED fan and the cheapest PSUs made. The PSU usually fries when doing serious gaming and your rig starts to reboot over and over. Youre not going to be gaming with a 300watt PSU thou. I suggest investing in a quality PSU with not only a lot of watts but a lot of +12V amps as well. If you're running a video card that doesn't require more amps than what your PSU has you may be ok but someday you may be replacing your PSU when it decides to retire. Anyone who says buying a high power PSU will fry components need to take a class in Electricity. A PSU only puts out what the system needs. At idle it puts out less--when hardcore gaming --more. Its underpowering a system with inept amps that damages it. Dont expect the $10 450watt PSU that came with your case to perform like a $70 450 watt Corsair.

PS craps out, usually just stops working. A ps function is to convert 120vac to 12vdc, 5vdc and 3.3vdc. It would be extremely rare for anything to go that horribly wrong to destroy your pc. Whether its a >$50 supply or not, they all work relatively the same.

In most cases purchasing and using a higher rated Power source will cause you more problems including frying your computer.
Replace with the same size, to be safe, otherwise you run the risk of trashing everything.

Shouldnt be problem at all. the components using the power suply onle take what they need. If anything; its better to have xtra, instead of components struggling to get enough juice. They can even fail then.
