TEST RESULT

RAIL STABILITY

As you can see rail stability is not as good as we were hoping it would be but still quite good for a 550W PSU.

POWER CONSUMPTION

Had we used up to 500W of power then the above results would not be what i call good but using up to 584W changes things.

NOISE LEVELS (SPL)

Noise levels are perhaps the only thing we had a tiny "problem" with the VPF550 since 48.3dBA at load is somewhat high.
