Hello guys,

so I've recently decided to upgrade my prebuilt PC:

Operating System

Windows 10 Pro 64-bit
CPU
Intel Core i7 4790 @ 3.60GHz 42 °C
Haswell 22nm Technology
RAM
16,0GB Dual-Channel DDR3 @ 798MHz (11-11-11-28)
Motherboard
MEDION H81H3-EM2 (SOCKET 0) 28 °C
Graphics
2476WM (1920x1080@60Hz)
2047MB NVIDIA GeForce GTX 960 (MSI) 45 °C
Storage
119GB SAMSUNG MZ7LF128HCHP-00000 (SSD) 29 °C
1863GB Western Digital WDC WD20EZRX-00D8PB0 (SATA) 29 °C
Optical Drives
WinCDEmu drive
TSSTcorp CDDVDW SH-216DB
Audio
Realtek High Definition Audio
 
So basically, I wanted to upgrade my gtx 960 to a 1080ti, but then everything started to fall apart. I have a 450w PSU, and after thinking about buying the 1080ti, I instantly realised that I'd have to change the psu too. I decided to get a 600w psu and that would be it. But then I took a look at my motherboard and realised that all of the ports are messed up. So my motherboard has a 14pin port for power (what the f***?). And then I said: "I'll just buy a new motherboard too." But than I looked into everything even more and noticed that my HDD and SSD have been connected to my motherboard with a weird 4pin to 2pin power connector. I had made a video that I wanted to show to my friend because he himself has made his own PC recently, but he is very busy right now, but I guess that I'm just gonna put it here.
I'd greatly appreciate some help with this. Sorry if the video is too cringeworthy, I had originally intended to send it to a friend.

As for video card upgrade, AMD Vega is coming very soon and prices are already very high so you would want to see what happens when Vega gets out. If nothing else, cheaper prices.

As for SATA drives, those are probably no problem PSU wise as power connector seems to be normal SATA power connectors. I suggest you sell whole system and buy totally new one as you'll need new motherboard, PSU and most probably case too. Try to sell that and get something better.

Well to be honest I haven't seen any other motherboards that support these HDD/SSD power cables:

Because thats how my drives are connected to the motherboard right now.

Yeah, that is very weird cable. Anyway black connector seem to be normal SATA found on regular power supplies.

The problem is you have a Medion using their own proprietary design. I'm inclined to agree with the suggestion to sell it and upgrade to something using industry standard parts.

So that means that if I would want to change my motherboard, I'd just have to get new power cables?

Edit: Oh wow, that's really messed up. Well then, I guess I'll just build a new PC completely from scratch then.

Lenovo does the same thing. 14 pin power and 2 4 pin SATA power connectors on the MB.

It really seems the only option for a significant upgrade on that PC yes.

I may be wrong but couldn't you get a new PSU, connect the SATA power cables from the PSU directly to the drives, forgetting the 4 pin connections on the motherboard and purchase a 24pin to 14 pin adapter?

I generally do not trust that kind of adapters but yes, that is one possibility. Still, buying new LGA1150 motherboard does not sound good idea as old motherboard is almost as good as junk and probably case too. So if that whole machine could be sold, it's probably better deal. There may also be somewhat nasty surprises when upgrading OEM machine.

Well what scares me about these 24 to 14 pin adapters is their safety. Wouldn't that fry my motherboard?
Edit: Exactly what Drillingmachine said, but selling a whole system is a hassle, especially an older one.

I'm not sure it would fry your motherboard. 

 

This page shows how a person made an adapter to accomplish the same thing as purchased adapter.

Optimally, you are better off selling the computer as other posters mentioned.

The adaptor would be worth a shot better than selling the system.
