I am looking at the EVGA SuperNOVA 550 GS and it looks like good and not expensive too. What do you think of it and also on the 650 PS?

The 550 GS is a good PSU but for a few more bucks I'd get the 550 G2, which is awesome (like all EVGA Supernovae G2/P2/T2).

Thanks, I read the review. 😀
By the way I don't think I will recap an old one if I don't find actually one that is alread good in terms of quality. The 400W unbranded I wanted to recap, have so absurd soldering on the back that it scared the hell out of me.. 😁

Those are good PSUs but only 100w and 110w respectively on 3.3v+5V, so 90w-100w if you don't max 3.3v+5v out.
You keep looking at PSUs with squat on 3.3v+5v. If that's what you want then those will do.

But in the case the wattage requested is more on both rails, which kind of protection good psu have? Do they shutdown safely or what?

Decent PSUs have over-current protection (OCP) and should shut down (theoretically) whenever the rails' max amp rating is exceeded. However:

- Sometimes the trigger point is set too high, and when overloaded the PSU fries before the protection can save it (relatively rare but not unknown, even from reputed brands).

- Modern PSUs 'expect' large +12V loads and tiny +5V/+3.3V loads, so the supervisor chip may only monitor the +12V rail/s for OCP, and not the minor rails (+5v/+3.3V). Example video.

Moral of the story: Don't rely on OCP as an infallible safety net.

BTW with gutless wonders you don't need to worry at all about OCP being present and working, for they'll typically explode well before their advertised max wattage 🤣 :

Understood. Anyway I am going to buy as soon as possible the Seasonic or the EVGA told. 😀

Some tests update: I am using the Corsair VS650 on a A7N8X-X and Barton 3200+/400 and basically the system is up and running and definetely bios reading feels the weight of the 5V rail. But I thought more; on the molex the with 512MB PC3200 1 DIMM, Geforce2 MX 440 AGP benchmarking it goes down to 4,83 volts in 3D and 4,93 volts on desktop. Air from the supply is cold as usual but I think I would exagerate if I'd use an heavy GPU like a Dx9.

Not so good, 3.2% deviation. Still within ATX spec but the VS650 is struggling to cope with that system.

yeah i think that too. I need another psu for that cpu.🙁

Hello, do you know this exact model of PSU? It's a 'decent' one? I've found it in the PC rescued today from the street: Re: I recently found this hardware, AKA the Dumpster find thread.

Model number looks like it's hidden under the side of the mounting cage. You'll likely have to remove the mounting screws and pull it back to see. The color scheme on the labeling looks a lot like an Enlight PSU. Makes me wonder...

Many people don't like Chieftec PSUs from ~2002 or so, I do. In my experience they are bullet proof!
It's always a good idea to open it up and look for bulged caps but I don't think you will find any.

Thanks for your advice, tomorrow I'll check inside the PSU

You'll know quite a bit if you can identify the OEM. There's a fair chance of doing so from the model number.

Yep, now I'm not in garage/lab, but tomorrow I'll read this model number and do some research

Perhaps it's a Chieftec HPC-300-202 300W?

Made by made by High Power (also known as Sirtec). At least all specs looks the same.

High Power = SirTec
Could be. Enlight also uses that line which explains why the label looked familiar. It looks like SirTec even customizes the labeling when they're under contract.

It seems the right one! The cables match, also... good PSU? Anyway, I'm going to the lab
