This review or rather presentation was very short. We couldn't possible imagine a serious test that could be done with an over-voltage protector, especially made for graphic card. The Spire PowerFuse SP162 is a new and possibly innovating product that has its potential market share among gamers and modders. We all know that there aren't many power supplies that can provide stable and sustain voltages to the whole system and especially in the graphics card. With the arrival of "energy sucking monsters" like Nvidia's 8800GTX, you need a really good power supply to keep them running. Adding an extra level or protection to your investment does really sound a good and clever idea. We have no problem recommending this product to anyone who needs it. We couldn't find a possible retail price but we imagine it should be really affordable, since Spire has a tradition in low priced (but qualitative) products.
