Oh damn, that's a completely different PSU. On the daughter board I can see the Metalfish logo and all other components also don't look like 700W Platinum. Seems the seller cheated you.
The seller has good reputation ( 2 silver crown), I dont think he will send fake products.

Hello, I bought this power supply on Aliexpress.
Dianjipa MF-700F. What can you say about it?

It has a different cable connection configuration. For 2х 6+2pin (on one cable) a 6pin connection is provided.


It has this factory fan and I replaced it with this Noctua because the factory one was so noisy.
I noticed that after a long load, Noctua also starts to make noise, the reason turned out to be that hot air from the video card passed through the power supply. I will buy a GPU with a turbo fan here.
Installed Noctua Noise Adapter NA-RC10 (with RC12 it didn't even start), now the noise is acceptable.

Now I have a processor with a real TDP of 90W and RTX 3070 (undervolt to 200W), I will probably install a 2080ti Turbo (undervolt to 220W) here so as not to heat the case from the inside.

But I'm wondering if this PSU can handle 3090 with undervolt to 280-300 watts? Just one 6pin connector for video card...
Perhaps I'll change the power connector on the Gigabyte 3090 Turbo so that it fits into this case.

as you can see from my initial teardown, the PSU you got has not much in common with the "original" 7760B / MF-700F (ENP-7660B clone) ...

the whole design and choice of components is totally different and since I haven't tested the PSU you got there, I can't give you much advice ...

however, I did some digging... it seems that the PSU you got sells in China for just 400,- RMB (USD 60,-) and based on my experience I doubt that you can buy a legit 600/700W PLATINUM FLEX PSU for this price... just for reference, the "original" 7760B / MF-700F sells for 800,- ~ 900,- RMB


anyways, I'd be happy if you share some experience with this unit. I'm really curious how much you can pull from that PSU...

As an avid follower of PSU reviews and threads over the years, this doesn't look like its build anything like a 600-700W PSU either. Seems like its using mostly low quality off the shelf parts....

I wouldn't plug anything valuable into that thing.

It seems sellers on Aliexpress / Taobao have started to sell fake even of their own Chinese domestic products so I'm not really sure what I would recommend to you.

If you want to risk it, you can try to buy the M700F from the shop I got mine via a shopping agent like superbuy.com but I'm not sure if they still sell the "original" one.

At this point, I'd just get the ENHANCE or SILVERSTONE 600W PSU to be on the safe side. IIRC, Overtek also offers custom cables if you order from them.

Yesterday I did a stress test for an hour. The processor was loaded at 90 watts, the video card at 240 watts (110% power limit). The power supply was outside the case and was not heated by the video card. As a result of the test, it became noticeably warm, perhaps 40 degrees, it felt much more colder than a hot video card.

But I will replace it, perhaps for this one, on the review from the buyer it looks like a real 7760B

If it's as per the images that is a genuine unit. fan is correct, transformer position right, case right and label position is the default location Enhance usually place it.

REVOCCASES, sanctions etc make it difficult for Russians to buy from us, but thanks for the mention.
