You misinterpreted that. What I was saying is that quality is not important in this instance as we know he has a quality PSU...I'm not dumb. Quality is everything with PSUs.

Again, I'm not stupid. I know that it's simple math, but it's not just the 12v rails that factor into the wattage of a PSU. That's why I said the bit about the amps on the 12v rail instead of making a completely pointless comment on the wattage.

In addition, is this it's peak load (i.e. limited in time to how long it can supply that ammount of current/wattage) or is it it's contiuous rating? Very important.
This is why I talked about amps on the 12v rail. It's not questionably branded because a company simply gives the summation of the wattage across all rails. If, as a consumer, one happens to be stupid enough not to be able to calculate the amperage/wattage of a particular rail before purchase, they shouldn't have their hands on a computer.

And if it is only it's peak load as opposed to continous rating (on the PSU that is), then your in seriously dangerous territory indeed.

Go and get that decent gear box! although, I'd prefer the analogy that the PSU is the engine - it's that important.
Affirmative. Was the PSU that you ordered single 12v rail? Those are the kinds I like to buy. No load balancing on the installer's part like in the olden days!
