Graphic Cards Using RTX 2060 with a 400w PSU?

[redact7701]

I have been eyeing a refurbished HP z230 (price:14k) for quite some time now. I was planning to upgrade the quadro GPU with used RTX 2060, which would total to a 25k (~14k+10k) build. The system has a 400w PSU and a free 6 pin pcie power supply for the GPU. the x16 pcie provides 75w and the 6pin 75w, so the system can take in a GPU of 150w, but i know that 2060 has a 160w tdp. this is the first time i am looking into all this. so i have some questions.
1. Is this safe? will the 2060 work? if yes, what might happen when I am gaming and the 2060 demands more than 150watts?
2. Should i use a 6pin to 8 pin pcie adapter given the situation to power the 2060?
3. or should i just use the 25k and wait save some more to build a i3-12th gen build with the 2060 that would cost me around 35k(25k+10k) .
4. or maybe use a <150 tdp gpu like, 1660, 1660ti or 1070 instead and call it a day?

The 6 pin included with the stock psu
The 6 to 8 pin adapter
learned about the 75w+75w thing from here
Aussie guy upgraded z230 with 1070 with a 6 to 8 adapter at 5:35

Don't buy this old machine mate. It's money down the drain.
Save a bit more and buy new generation so you have an upgrade path later too.

If you're eyeing used hardware anyways buy something newer from used market, at least 10th gen or newer would make sense.

You really don't wanna go down the path with z230 because the components are proprietary and if anything goes wrong with mobo or PSU then you'll have to find the exact same component.
I have a cousin who has a z240 with dead PSU or a mobo. Can't figure which one because of proprietary hardware.

2060 in itself is not bad. It's a potent card and still good for 1080 with mid to high settings depending on the games. Better than 1660 super so you know what to expect. However, the rest of the system is gonna be a burden if not now, maybe 6 months from now (Note that it's not hardware age, that ship has sailed a long time ago, In six months you will start noticing all the shortcomings of your system may be even earlier). Again 400W PSU shouldn't be your big concern either. It's DDR3 man what more should I tell you?

Here is a similar machine, though it's old still better than the HP machine and has some upgradability

PSU: 450W - 1200-1500 Used - 2500-3000 New
Mobo: b450m - 4500 (New on MD computers), even less used let's say 3000
CPU: R5 3600 or better (5000-7000)
DDR4 RAM: 3000 for a used 2x8G (You can get a new DDR4 set for 3000 albeit at a lower freq of 2400 or 2933 MTs)
Cabinet: Get a cheap one that comes with preinstalled Fans that's all (1500-3000) New/Used

See around the same budget you have some respectable specs for gaming.
