But why would I need multiple +12V rails for?

just 350....this is not enough for your computer......you must have above 500watt....I doubt that PSU comes with case that doesn't gave actual power for the system.350 watt
You don't need to worry about whether it's single or multiple +12V rails. Single is better actually.

I was always told that multiple rails were better.Could you please enlighten me?
Here are the facts: A large, single 12-volt rail (without a 240VA limit) can transfer 100% of the 12-volt output from the PSU to the computer, while a multi-rail 12-volt design has distribution losses of up to 30% of the power supply’s rating. Those losses occur because power literally gets “trapped” on under-utilized rails. For example, if the 12-volt rail that powers the CPU is rated for 17 amps and the CPU only uses 7A, the remaining 10A is unusable, since it is isolated from the rest of the system.
Since the maximum current from any one 12-volt rail of a multiple-rail PSU is limited to 20 amps (240VA / 12 volts = 20 amps), PCs with high-performance components that draw over 20 amps from the same rail are subject to over-current shutdowns. With power requirements for multiple processors and graphics cards continuing to grow, the multiple-rail design, with its 240VA limit per rail, is basically obsolete.

Are you going to actually answer any questions asked of you, or are you just trying to get the secret magic answer?Have you replaced the PSU yet?
