Windows 7: Can I use a HP 400z PSU for testing purposes

Can I use a HP 400z PSU for testing purposes

I have a PSU from an HP 400z MN/DPS-475CB-1A and I would like to know if I can use it to test computers that might have bad PSU's in them. I don't want to burn anything up. I know that the dimension of it is a little bigger than a regular size PSU, but i would just hook the wires up without installing the PSU. Any help would be appreciated. Thanks

Hi that really depends on how many watts the power supply is. what hardware other computer have mainly if it has a stand alone graphic card. some cards will require lot of watts.

would be fine in my opinion to test machine with integrated graphics. but on added graphic card might not be big enough depending on what card is in it.

If the wattage is too low you can take out the GPU and just use the built-in, remove the optical drive and only use one RAM stick for testing purposes.

Creating a standard user account for security purposes?
Hey forum, I never thought about it until recently when a friend mentioned it. He said even though I am the only one that uses my computer, that I should still create a standard user account and use that to greatly increase the security of my system. This seems to be sound logic and I have heard...

Is 32bit Win7 better than 64bit for most purposes?
This is just a personal opinion and others may very well disagree. But I think Windows 7 64-bit is better than 32-bit simply because of the ability to make better use of installed memory. A 32-bit machine is limited to 4GB minus whatever memory might be set aside for graphics, etc. Most folks see...
