Does this 12v Speedfan chart (screenshot) look stable? (new power supply)

Hi,

Does this chart look stable, I got a new power supply and am testing it out to check if it's up to scratch:

Seems to run between 11.93 and 11.99 (11.88v under heavy load), my old power supply ran at around 12.3 and the system ran a couple degrees cooler?

Wondering if that line should be straight and not all zig zaggy?

System is:

AMD A8-6600K APU @ 4.2Ghz/4.4Ghz Turbo
AsRock FM2A85X Extreme6
GSkill 1866 memory
COOLER MASTER GX 450W ATX12V v2.31 80 PLUS BRONZE Power Supply

what's the make and model of the PSU?

That's a pretty minor variance and well within ATX specifications.

Updated post. a COOLER MASTER GX 450W RS450-ACAAD3-US 450W ATX12V v2.31 80 PLUS BRONZE Power Supply

I checked this system and it pulls ~175 watts max at the wall using an accurate KillaWatt type power gauge (Ensupra)
That was while running Prime95 64bit and 'HeavyLoad' simultaneously.
Runs as little as 72 watts idle.
