lmao blitzen my computer psu on the edge your kidding right an sli 8800gtx system has a minimum power requirement of 420W............... the maximum any computer would ever need is 550W and large number of amps on the rails. I have built 13 computers for friends and family my psu is enough I have tested the power intake and it is 312W on start up (everything full power) so mine is comfortable.
Blitzen no offence but your system isnt anything special and you have 620W that is just stupid why pay more for what your not going to use atleast you chose an ok brand.
I wasn't spiking for business I meant my comment only as I will suggest what computer parts he would want. For the pcs that I have built for people I only charge them £20 service charge for full setup and configuration and software installation.
I run a multimedia server on my LAN network at boarding school from that I get a monthly income of £3,000 in subscription fees that subsidises the cost of my time to build a pc.
