[SOLVED] What wattage would be enough for I5-2400+gtx960 combo?

[CyrilP96]

Hi, Ive managed to get an old Fujitsu prebuilt PC from our office, Its Fujitsu ESPRIMO P900. Featuring pretty <Mod Edit> motherboard, I5-2400, 4 DDR3 slots and proprietary PSU with 2 12V line each by 15amp. I have an old reference gtx 960 and im thinking about pluging it into this pc, problem is it doesnt have 6pin connector nor molex connectors. I found that there is an option to use 2x sata to 6pin adapter. I dont know If I should try to do so, Ive seen some scary psu failures videos, on the other hand this psu should be rated at 90% efficiency.

If it doesn't have a 6-pin connector, you 'd better just buy another one.
As for the wattage: https://outervision.com/power-supply-calculator (load wattage there). It (almost) doesn't matter what is the efficiency, adapters can serve other purposes normally, but this one is really risky. The risk here is lower than what would happen if u try such stuff with a gtx 780, but still the PSU may get fried pretty easily. The capacitors are not manifactured in a proper way to support the gpu safely.

Problem is that I have other PSU but this motherboard takes proprietary PSU from fujitsu with 16pin motherboard connector. I just want to built cheap 1080p capable low cost pc (basically no cost since I have all the components as spares).

Do not use an adapter. Get a 450-550 watt PSU with the correct cables for your GPUs requirements. The Corsair CX 450 or 550 are a good start.

Man, do whatever u want. Many of us PC builders know how going this way can end.

On one side is the fact that this GPU is among the ones with lesser risk to destroy things.
But on the other side it still wants its (up to) 120 Watts properly delivered, so don't be amazed if after 1-2 months an interesting smell comes out of the pc and the PSU gets dead. Srsly, you'd better search for a regular or modular 16-pinning one, that has a 6-pin connector. Don't hurry to just make a mistake.

I was just wondering if its really that bad idea to try run it on that PSU. I have this older hardware just sitting here, PC was destined to go to recycling center so I took it home since its working flawlessly, there is no need to kill its PSU, Ill probably pair it with some second hand 1050ti and give it to my younger cousin so he can play some games online.

Problem is that I have other PSU but this motherboard takes proprietary PSU from fujitsu with 16pin motherboard connector.

I didn't see this comment when I posted mine.

Unless you can find an adapter to upgrade the PSU, you will have to make your own adapter. Your only other option for a PSU upgrade is to run a second PSU outside the case just for the GPU. I think you might be better off getting a different motherboard for maybe double the price of an adapter, assuming you find one.

If the PCIE x16 slot is a full spec 75watt, you could run a GTX 1650 (not super) as the fastest GPU possible without requiring a PCIE cable and without changing the PSU, but the PSU is very old by now, so it may not be a good idea to strain it that much.

Well, this sounds like a better idea.

Really? Aren't there any full-modular or similar PSU options for a system with 16-pin?
As for the 1650 yes, it's the best possible option in similar cases. However, the price is big, and the type of bottlenecks both GPUs would run into would probably kinda' equalize the two GPUs, not to mention the higher risk of 1650 to get rejected by the older motherboard. As for the 75 watts, most likely this wouldn't make trouble with GPUs, bearing in mind an old dq45cb of mine works pretty well with a gtx 1050, but ofc there is a 24-pin PSU connection...

You know what, you can put an adapter and the gpu in the PCIe slot, and run 2-3 benchmarks in short time. If it shows good results while using it in the short period, and if there is a cheap 1050 ti, that doesn't require a connector, then this may be the way to go.

Or maybe not...damn, this makes me think about it much, cuz there still is some risk, even in low periods. This may require changing and adding more than one component of the overall system, and you have to also keep in mind you need a proper overall wattage. Your system seems like it would want more than 350 watts. I left a link to the calc in the beginning.

The system itself will be drawing somewhere around 70-75watts idle and 110-115 watts under gaming load. So with a 75watt GPU (1050 TI/1650), the systems 280watt PSU should be enough. The issue that CyrilP96 has is it's an old system, which means it's an old original PSU and it could be a major point of failure when running a higher end GPU than say a 35watt GT 1030.

I honestly wouldn't even invest anymore money into the system as it is. The CyrilP96 is better off buying a used motherboard to replace the current board, so they can use a new standard ATX PSU and an even faster GPU. The i5-2400 is actually slightly faster than a Ryzen 3 1200 and about as fast as a R3 2200G, so it's not completely obsolete for games that only need 4 CPU threads. A GTX 1650 Super would be a decent match with an i5-2400. Even though it will be bottlenecked, I would personally get something even faster if I knew I was going to be reusing it in a new system.

Thank you for your advices, Ill put there some second hand GPU that doesnt require 6pin connector. Im too lazy to make and adapter for this old PC, it would be pain in the ass since it has 2 connectors one 16pin looks like 12v only and another is for lower voltages, assuming by the colour of cables. I just hope PCIe will be able to supply 75w.
