If you are assembling a gaming PC for yourself not for all the money in the world)) but you need a powerful unit so that there is still a reserve, then this one is just right. So far this 700 has been enough for me for both 1070 and 2070
+ long cables for video cards
+ black color - it can easily be placed in cases with windows, it won't spoil the look
- you can now install a fan with a larger diameter..

If you're really short on money and literally have no more than 2k in your pocket, then you can get it.

PSU arrived without a power cable... Moreover, there wasn't even a spot in the box for it... Had to run to the flea market in the nearest basement. There aren't enough characters in the "conclusion" field, so I'll write here. If you're completely out of money or need a PSU for office installation, it's a decent option. If you're buying for home use, spend an extra thousand rubles or so. For 3100-3200 at the time of writing this review, there's an Asus TUF 450W available, which is a million times better.
The price is decent. Among the no-names, it's the cheapest. Quiet enough.
Seems not, except for the aforementioned power cable.
If you don't mind these drawbacks, feel free to make the purchase.

Bought this PSU, bought a case with a bottom PSU slot, and also had to buy a 4-pin extender.
Price, build quality,
Only 4 pins for the processor, smells like plastic, short cables (especially 6-pin ones), thin cables.
