Toms hardware psu tier list
What I mean is that, even a power supply that has a noise above the ATX spec, it will most likely still work without issues on most PCs. (btw 120 mV peak to peak of noise is already a very good value in general switch mode power supply design, and this is the noise of the power supply alone tested in special conditions (PSU alone connected to a resistive load, a few capacitors IIRC), turns out that graphics cards and motherboards add a lot of capacitance to the system, greatly reducing the noise after all.
TOMS HARDWARE PSU TIER LIST PC
(In fact it would be a problem of the rest of the PC if it needed a power supply with ''better'' specs than that).įor example, noise at 12V rail at 120 mV peak to peak max. There are several problems with these requirements:įor one, ATX specifications set the requirements perfectly, any PSU that meets them is complaint and safe and can be used in any PC. Tier A and above - required to have ZVS (LLC or phase shift resonant topology), have ripple below 50mV under all load situations including 110% overload, 30k hours MTBF fan (generally non-plain-sleeve bearing) or be fanless. I've seen several times the PSU tier list being put here, and they just a gross oversimplification of how things work with several misunderstandings at best, or complete marketing BS at worst, So I'll go into detail.įirst, lets dive into the methodology of the tier list at LTT.
