is a 700 Watt Power supply good or okay for a RTX 4070 Super and an AMD R7 8700f

[Tazkari]

I bought a PC, and I changed from 600 Watt to 700 Watt, but I don't know if 700 Watt is good for the PC. My other specs are
MSI-B650M-P
32 GB DDR5-RAM, Dual Channel (2x 16 GB), 5600 MHz*, Kingston Fury Beast
1000 GB M.2 PCIe 4.0 SSD Kingston NV3
700 Watt BoostBoxx Power Boost, ATX2.53, 92% Efficience, 80 Plus Gold zertified (I don't know much about the Power supply but it was cheap)
I don't know if its necessary but i got a Deepcool Gammaxx C40 Processor fan

Yes if it was a known quality brand like Corsair or Seasonic

If it was cheap. Its probably terrible.

I can find it for 70 Euro which tells me its probably a mid-range 700W unit which seems OK. Not heard of the brand before so I personally wouldnt trust it but thats just me.

Should really get a better PSU. Should have an atx 3.0 or 3.1 for rtx 4000 series, and from a reputable brand. BoostBox is questionable at best.

DONT BY ANY TERRIBLE PSU OR YOU WILL BE BLOWN UP FOR THIS BOMB

Why the PSU change? (curious)
This PC can be powered easily with a 550~600W PSU.
If the budget is limited its better to go with lower watt but a known quality one instead of a bigger but unknown, potentially inferior PSU.
PSUs are the heart of PCs

looks like they are made for CSL, but not sure about the OEM

you can look at what my specs are which are bit more higher on power draw then what you have and under load with a 4070 super is only around 400-450watts of load. granted i have a little bit under volting on my 4070 super but you would still be under that.

Shell looks the same as an MSI MAG A-GL box (picture below), probably skimmed down to non-modular to save on price. Internals are probably similar if it's the same factory. Should get the job done.

Brand doesn't matter. Check the rail ratings. This is yet another stupid minutiae.
We rate power supplies by wattage output which is the entire point.
Nobody changes out power supplies very often. Myself included. Last one was 15 years ago.
We use these flat ratings of 600/750/850/etc to quickly compare this and that and there's a LOT of junk getting sold today.
How? Critically important designs change over time, like that ATX 3.0/3.1 cert and completely insane 12VHPWR connector.
Will it burn the house down? We don't know but so far ANY search of 12VHPWR nets this instant image result:

So...Yeah. My semi-modular 2009 era Antec EA-750 has a split rail design that tops out at a grand total of 25A.
The other day I chose this thing. 1KW rating, fully modular, tons of PCI-E cables and a pair of high current 12V rails that top out at 83A.
I'm good for the next few generations of accelerators or until my completely insane overclocking demonstrations get the better of it.
Other than that, pick a supply that has good length and strength cables, a pleasant no/low noise and you're solid.
Your 58A rail might be a valid contender for now with whatever you decide to run next but we will all eventually come back to this issue.
