Could someone have a look and tell me how many watts my power supply is supposed to be?

If I understand it correctly it's 350 watts, right?

Okay, there’s so much info on there I wanted a second opinion. Thanks.

Isn't ISA obsolete? Just for clarity, my computer is seven years old. Not really new but recent enough to not support ISA.

I don't see a -5V signal, needed by some ISA cards.

It's also biased towards 12V output, so this is best used with a system that has an ATX12V connector.

With FSP model numbers the FSP350 means total watts is 350w.
The other ratings are limits for those rails but they don't add up to the total for the PSU.

Think like two trucks on a bridge.
Each truck can hold so much weight, and the bridge can hold so much weight.
The two truck limits add up to more than the bridge limit.
You can shift the weight between the trucks so long as neither truck is overloaded AND the bridge isn't overloaded.
Total watts is the bridge.

Okay, so I made a bit of an ass of myself. Anyone care to let me in on the joke? 😀

Only verry specific and old ISA stuff use -5.

I am aroused about any X86 motherboard that has full functional ISA slot. I think i have problem. Not really into that original (Turbo) XT,286,386 and CGA/EGA stuff. So just a DOS nut.

I looked it up btw. ISA has been obsolete for 27 years now. Why was this whole -5 volt/ISA thing relevant if my only question was a confirmation of my power supply's rating?

in case you wanted to use it in a PC with ISA cards, which a lot of people here do.

just like a lot of people play games that were made for an obsolete OS.

Aha, now I see what happened. Were you all under the assumption it was a loose power supply?

Uh, no, we were under the impression that you had come to a retro games forum, where people often play retro games on retro hardware. Within these forums, ISA is very much alive and well, so it's extremely relevant. If you don't think so, that kind of makes you the outlier around here. No snark intended with that remark, it's just the context in which your questions will be viewed. We can't assume you DON'T care about ISA because it's relevant to the interests of the people who frequent this place, so by default we assume you do. If you don't, that's fine, but don't be surprised when that's taken into account with the answers you get. You just have to be more specific.

It's obsolescent. ISA devices still work, barring malfunction. You can still buy new ISA gear in the PC/104 and industrial world. It's simple and, in a lot of situations, sufficient for the task.

How was my initial question not specific? I was under the impression that a simple confirmation about the info on a PSU's specs would not start a lengthy thread on a forum where people are obviously into computing hardware retro or not.

Just to avoid any confusion, perhaps I should have gone to another forum altogether. It's too late for that now and no longer necessary. My questions concerning a relatively modern PC supporting PCI-e only have been answered.
