+12V is 8.245V in HWiNFO

[Seek54]

I was reading a thread about CPU temperature and it mentioned voltages, and since I've heard that my Inter-Tech Energon 650w PSU is not very good, I decided to check. This what I see is this: https://prnt.sc/gq2psu
Is this bad?
Thanks.

Variance is usually +/- 10%
Both your +12V and +5V are showing more in the -30-35% range.

Although the PSU is likely junk, those reports are likely to be due to a faulty/non-calibrated sensor, opposed to accurate readings.
I wouldn't expect any resemblance of stability if those numbers were true.

So I should just leave it as it is? I will check later if it's the same in the BIOS.

Your PC most likely wouldn't turn on if 12V was truly under 10V and HWInfo is known to have sensor value mapping issues causing it to incorrectly interpret data from monitoring chips found on many boards. I had the same problem on my Asus P4P and P5Q motherboards with 12V being reported as 8V. I think there was another voltage rail with clearly mismapped values, don't remember which.

The only true way to know is a multimeter, although BIOS/other programs reporting the same thing would be a quick/easy check.

1. The OEM appears to be "Huizhou Xin Hui Yuan Tech" who I've never heard of.... likely some junk
2. The PSU has no 80+ rating (although just because a unit HAS an 80+ rating does not make it "good")
3. The unit has a single 8pin PCIe connector, is a low-end 4x 18A 12V rail design (with a combined 550W 12V max, so 45-46A)

That PSU is more akin to a doorstop than it is to a PSU. I'd highly suggest replacing it before it causes any damage.... or worse.

In bios the numbers look better: https://prnt.sc/gq3cmt
I should still consider a new PSU right?

 

[Barty1884]

The numbers look a lot better there, so it's most probably an issue with HWMonitor/INFO as InvalidError mentioned.

That being said, yes, I'd still suggest you look to replace that PSU.

What PSU would you recommend?
Current specs:
I5-3350p
GTX 650Ti 2gb
1tb sata 7.2k hdd
12gb (8+4) ddr3 1600mhz ram
Gigabyte h61m-s1 rev 2.2

I may be upgrading almost everything pretty soon though.

Depends on your location, budget & components.

Given you're running an H61 board, I would expect you don't want to invest too much into this setup?

If you're ok with mail-in rebares, the CX450M (2017) can be had for $24!!

Unless you're running a very power hungry GPU, that should be more than capable.

That PSU should see you through any single GPU upgrade.

I was thinking of i7 7700k gtx 1080 16gb ddr4 same hdd+samsung 850 evo 250gb? But since 8th gen should come pretty soon I'm gonna wait until then. But I don't think 450w is going to be enough for that?

 

[Barty1884]

91W TDP CPU (7700K) + 180W GPU (1080) + say 30-50W balance of the components.
Puts your right around 300W or so, before OCing.

A good quality 450W unit (which the CX450M 2017 is), would handle it just fine.

You might want a little more as a comfort level, but the efficiency level (of a bronze unit) doesn't change much between 50% and 100% load (85% and 82% respectively).

Those efficiency differences would equate to <$20 annually, with 24/7 100% usage.
