New system, new power supply?

[megabytehl]

I'm planning on purchasing components for a new system. I've got a time tested Antec TruePower II 480w PSU in my old computer.

My new setup looks something like this:

Q6600
8800 GTS 320mg
Gigabyte DS3R
2x1gb OCZ DDR2 800
1 SATAII HDD
1 DVD+-RW

Will I need to purchase a new PSU along with my system?

What is the max current on the 12V rail.

 

[MarcVenice]

has to be 30a or so. With less things could get tricky .

The 480W TP 2 offers a max of 31A on the combined +12v rails. You should be fine.

My similar rig didnt have enough 12v on the PSU in sig, its 27A.

Corsair 520HX is on the way.

Would the signs of a 12v rail inefficiency be the same as a power supply that doesn't supply enough watts? What were the signs of 12v lack of amps?
I only ask because I'm building a rig almost similar to yours (Q6600 GO stepping, and the 640mb EVGA 8800 GTS) and have a power supply (520w) that supplies 33a on the 12v (single rail).

I was getting very large vdroop and stability issues, random reboots, and artifacing in games at load.

The exact same rig with a E4300 ran fantastic, swapped the Q6600 back in, all of the same symptoms.

Parts are in the mail, I'll let you guys know how bioshock runs on Wednesday

It might not be due to the "A" on your +12v. 27A seems quite sufficient.
You might better off getting PSU with 8-pin CPU power.

Most people buy power supplys bas on totaL amps ...watts really does not figure into the equation!
