[SOLVED] I am using a power supply on which 15V has 11A and 5V has 15 A, is it safe to use it?

[Loky_4]

I am using a power supply on which 12V has 11A and 5V has 15 A, is it safe to use it? Its running good so far..... The CPU is i3 8th gen processor, Gigabyte H310m mobo, 16 GB ram, and 120 GB SSD that's it. The PSU is Zebronics Black gold 450W

The previous PSU I was using was zebronics ML 450W on which 12V has 15A and 5V has 38A.

Because of the lock down I had no other options, any advice is appreciated.

No. That is a very unsafe idea.

Heres why:

First of all, I judge power supplies on a "guilty until proven innocent" basis, since the damage that a poor quality PSU can cause is devastating. Since I have never heard of Zebronics, I would assume its bad and never use it.

Poor quality PSUs would be at a high risk to fail, and can easily damage hardware (high ripple, overvoltage, etc), even if they don't fail.

After I looked up the specs page, it seems I was right, it's downright bad.

Heres a comparison between a proper 450w PSU and the Zebronic "450w"

Corsair CX450M
+5V@20A, +12V@37.4A
Zebronics Black Gold "450w"
+5v@15A, +12v@11A

Notice how the good 450w PSU has 448w or almost the full 450w on the 12v rail. Your PSU has 1/4 of that, indicating that your PSU is likely both very old and lying about its 450w output rating.

The pathetic 132w amount on the 12v rail is so low that it may not be enough for your setup, even just running an i3 without dedicated graphics.

Your PSU only says it only has over-voltage and short circuit protection and lacks any mention of the protections like under-voltage protection, over power protection, and over-temperature protection. I would consider your unit downright unsafe without these protections.

Honestly, I would throw that power supply away, or maybe recycle it for the metal. It doesn't belong in any computer.

Sorry for the ping, but i am curious to see what @jonnyguru thinks about this!

that psu is pretty much junk. quality psu's tend to measure total power from just the 12v rail. the other voltages are used little so the extra few watts they take is not important really.

that psu has 12v x 11 amp = 132w !! for a psu to claim to be 450w, it is actually not even close as you can see.

this alone tells me this is not a good unit. throw in the lack of any built in protections and it is an accident waiting to happen. this does not even consider what might be inside the object. i'd wager big money that the cheapest possible internal parts were used making this as well.

do yourself a favor and get a quality unit that delivers what it claims

No. That's a really old and poor quality PSU.

No. That's a really old and poor quality PSU.

that's my guess looks like one from many years ago when you actually needed big 5v and 3v rails. but i did not look to deeply into it. since you're the expert will take your word for it

Thank you for the info, this lock down has forced me to live with this, I could not source any new PSUs at the moment...🙁
