[SOLVED] ASRock B450M-HDV PSU compatibility

[Jake Witherow]

This may seem a bit of an obscure question, but I need to know whether the 'CiT 600W PSU 12cm single 12v CE PFC '600UB' is compatible with the ASRock B450M-HDV motherboard.

My GPU is a RX 570 8GB, and my CPU will be a Ryzen 5 2600.

Thanks in advance.

Is that a PSU you already have?

Yes, the PSU I mentioned in the question I already have, but I don't have the motherboard yet but I was planning on getting it.

Compatibility-wise. No issue.
HOWEVER, it's not a good PSU.

Leave this here:

Basically everything runs off the 12V rail(s). Each rail is only good for 12V * 18A = 216W, but likely only 358W combined. You've got an [effectively] 350W PSU, not a 600W one.

Thanks for the answer, really appreciated.

So performance wise, will the poor PSU effect the computer negatively? I'm talking a mixture of general browsing, watching HD videos and gaming (which is the main thing).

Sorry, I'm no hardware expert.

May create instability over the long run. If the CPU and or GPU has a weak power signal it will lead to crashes.

Hmmmmm. "negatively" is a vague term.

• IF the PSU doesn't fail. Each component will perform as it should.
• If the PSU is borderline, you may get system crashes
• If the PSU dies peacefully, you have to buy a new PSU
• If the PSU dies violently, it could fry other components (mobo/CPU/GPU/storage/etc) in any quantity.

Are any of these more likely than the others or is it sort of just down to chance?

I listed everything in best to worst for this purpose. The lower quality your PSU, the more likely the lower listed events are to happen. Age also plays a role here.

*with the partial exception of #2 which can happen to high quality PSUs that just aren't high enough wattage for the system they're running.

I would say #3 is a very real possibility for your current PSU. Hopefully not #4 (nobody ever wants that) but certainly some possibility.
