Ok for some home projects I decided to get one of these: http://rosewill.com/products/1763/ProductDetail_Overview.htm[1] It's a small device used to test if your power supply is good or bad. Why? Well if you have a PC that is dead ( you power it on and nothing happens ) you have a problem. The next logical test is do disconnect everything from the power supply except for the mother board. Next power it up again, if your monitor shows the Bios started then you most likely have a good power supply. Other then that test one usually has a spare power supply to swap to see if the mother board is bad. With that said, I and other have found that test is really no longer valid. Power supplies for all makers are failing, in different ways. Thus I bought a tester to verify my collection of PC and spare power supplies. I regularly read the Anandtech Power-Supplies forum. I've seen it mentioned there many times that to adequately test a switch-mode PSU, the PSU must be under load. From looking at the overview and specs of the Rosewill PSU tester, it is unclear if this unit presents an adequate load, or if it is just a multimeter with PSU connectors. -- Phenom II X2 555 | Biostar TA890FXE | 2 x 4G DDR3 1333 | Maxtor 80G PATA | GeForce 210 -------- [1] http://rosewill.com/products/1763/ProductDetail_Overview.htm
