!This should be of particular interest if you are purchasing the 8800gts, it's power hungry!
This is a 430w PSU, with 38amps on the 12v rail(you will need at least 25 for the GTS alone) and a lifespan of 400,000 hours(about 45 years, lol). It also has a around 85% efficiency making it one of the most efficient PSUs around which may well save you money.
It also has dual pci-e connectors if you want to go SLI and complies to the atx 2.2 standard. Sleeved cables too which can help the airflow in your computer and keep temps down!
At 33.60 delivered it's a cracking price which you won't be able to match anywhere else so if your current PSU needs an upgrade you should consider it.
