Worst damage a PSU can do to your hardware?

post #1 of 33
Thread Starter 
I have a Xion Powerreal 700W and I hear it isn't a very good GPU. Well I play on Crossfiring my 6870 soon and I need a new PSU. But in the meantime, what is the worst thing that can happen while using this PSU (to my hardware)?

Also, if I buy a new PSU, would it be necessary to remove the MB and everything while removing the old one and installing the new one? I don'r feel like it is necessary because of my case, but it is always nice to ask.

Everything goes ?

Worst thing I had happen to me was a blown motherboard and HD from an HX850 going. Plus when I was using a raidmax psu when I was a noob 3 cd-roms went.

Fry all your components. It happened to my old PIII system. Only things I was able to salvage were the HDD and the optical drive I think. Never ever skimp on the PSU, it's the most important part of your system.

And no, you don't have to remove all the components when switching PSUs.

Absolute worst? Motherboard, CPU, RAM, graphics card, hard drives, and optical drives all fried.


Don't Crossfire on your Xion.

Don't do anything you don't have to do in order to get the old power supply out. Typically, it means you don't have to remove anything but the PSU in order to get the PSU out. So you'll know what has to be done when you do it.

Now as far as what can happen when using crappy PSUs (I do not know if the Xion PowerReal is a crappy unit or not - that JonnyGuru review confuses me), the worst that can happen is if the PSU fails or dies during operation, then it can kill at least one component that is depending on it for power. There's also the chances of your entire system being taken out by the death of a low quality PSU. Although again, I do not know how good or bad this particular PSU is.

The risk of failure is dramatically increased with overclocking because it puts more stress on the PSU, although not due to the increased average load.

Psu is very important but not necessarily the brand but more the features. You want a short circuit protection and some sort of voltage protection so it doesnt fry your components. Most newer psus have this that are decent such as corsair or powercolor, xfx and the obvious top ends one made by seasonic. The lower end ones probably do not have any voltage current protector or uninterruptable supply so when it goes every one of your components are at risk. You dont need top end but avoid those 40 dollar 650 watt psu's, especially for crossfire.

What everyone else has said plus if you're really unlucky the PSU catches fire and ignites anything nearby.
