Doublet power supplies

I welcome everyone.

Introductory:
1. There are two power supplies of 250W.
2. After the upgrade, the required power of the PSU is 500W.
3. We do not consider the problem of placement in one case.
4. All necessary connectors are available and compatible with consumers.

Question:
Can they be used together, distributing the load proportionally?
(one - for a video card, etc., the second - for a monitor, etc.)

You have nothing to do at your leisure, don't mind spare parts, have you enough knowledge in the field of electrical engineering? If the answer to all these questions is "yes" - there are a bunch of articles on the Internet with a detailed description of the options for implementing this task, as well as problems that may arise during and during operation. If "no" - save money for a new block. By the way, a similar topic has already been in the forums on this site, you can search, but it seems like they came to the same conclusions that I voiced a little higher.

Thank you, the question has been cleared.

in principle, you can use one for the video card and the other for everything else.
the only difficulty is either soldering a pair of wires to a 24-pin. Or, in search of a full-fledged 2 bp plug
, I myself, however, did not do this

I am reporting the results.
This was enough for me (I post it for the same, "overshadowed by thought"):

Perfect answer:
“Yes, you can. Just keep in mind "2 PSU" does not mean "2 sockets", and PC components are not 2 bulbs. Features are as follows: turning on the power supply is not just "On." on the back panel, and contact closure through the motherboard. It is necessary to connect the PSU together here and there. Consumers differ: 12, 5 and 3.3 V. With a disproportionate load (incorrect distribution of specific consumers by power supplies), "voltage imbalance" is possible (and now - "google for help"). Well, do not forget about the efficiency of BPshek (cheap ones from 0.3 to 0.7).
In short, yes, but - well, it's on ... "

1. Read carefully: "If" no "- save money for a new block." And don't take words out of context.
2. Why? At least try to follow the links I have indicated.
3. If you do not know from which side to approach the soldering iron, then I do not need to "save money for a new unit".

Thanks for the moralizing - I'll go cry with a soldering iron in an embrace ...: D
Only I have no problems with the power supply unit - except that I clean the cooler of dust and grease it so that it does not make noise.

It was not a preachy, it was a response in your style. And that you have problems with the power supply - I did not say)) I
just did not consider, asking the question that a primitive procedure - to connect certain wires in a certain sequence - requires special knowledge in electrical engineering.
And the fact that I cannot distinguish a diode from a triode is a fact.

It's good that you figured it out yourself.
And I, out of stupidity (^ _ ^), immediately took a power supply unit "with a margin" - too lazy to solder later, climb forums, etc.

You can. Connect the second power supply unit as an external one and put a jumper to start. And the power consumption of each device (or at least a model), please go to the studio.

On - Not Just "On" on the back panel, and closing the contacts through the motherboard The motherboard is
not required, a paper clip will do.

I thought the 2x250 option would not work for all consumers. If, ideally, 250 + 250 = max350, and the monitor is directly plugged into an outlet, nothing changes: video (150) plus mother / percent (100) plus diskS must be powered for one power supply ... well, that's it ... If one from a 350W PSU - it's worth a try.
Or sculpt a single power supply unit based on 2x, but that's another story ... (hello to SonyK - this is already too lazy for me).
Thank you for your answer.

You are engaged in theory. Try it in practice, everything you wrote should work.
1 bp on the motherboard with hard, 2 bp - on the video with the process. It is in this sequence that there is no timeout, if memory serves me - therefore it is not necessary to run everything synchronously. The only troubleshooter is an open case.

I 'll try. In the end, it just won't turn on, if that.
