Dell Precision 3660 + PSU 1000W

Did this solution work with out getting additional cables or adaptors? I have the Dell Precision 3660 (300W) and I need to upgrade the power supply.

@Biofoundry​ I bought a L1000EPS-00 power supply, but I haven't replaced it yet. However, I compared the power supply cables with the description in the manual and everything indicates that no additional adapters or cables are needed. I checked the load with a wattmeter while playing GTA V and Mafia Definitive Edition - the measurement result is about 290 W maximum. During normal use (internet, VoD, Visual Studio + running virtual machine) it is about 90 W maximum. Computer configuration: i7-13700, RTX 4060, 3x nVME, 2x HDD, 500 W power supply.

@mariusz.g82 Thank you. I have this spec. It is not used for gaming, but for a robotic automation system with a huge number of USB peripherals. Where did you get the PSU from?

13th Gen Intel® Core™ 1913900 (36 MB cache, 24 cores, 32 threads, 2.00 GHz to 5.60 GHz Turbo, 65 W) Windows 10 Pro

@Biofoundry​ I bought it on one of the sales platforms in Poland (I live here). I don't know where you are from, but I found a lot of offers for the power supply on ebay.

Compatible power supply models: D1000EPS-00, L1000EPS-00 and AC1000EPS-00.

@mariusz.g82 I am in South Africa. I will have a look to see what I can get here. Thank you for the PSU model numbers.
