If you missed my other thread - I haven't been a gamer since the late 1970s so I don't know anything about this stuff.
I'm going to buy an Alienware Aurora R16 next week. The only PSU options seem to be 500W or 1000W. The PSU is proprietary. I'm going to buy my PC from one of the following...
-
New from dell.com. Both PSU options are available.
-
Refurbished from Amazon Renewed. There are no power supply details. That's even true if I use plain old amazon.com and look at new models.
-
Refurbished from outlet.us.dell.com. Both PSU options are available.
Amazon Renewed might be cheaper but it annoys me they won't give the info. Even if 500W is fine for me - I'll like to have that "in writing" before I buy anything.
I'm going a PC at least this powerful...
-
Processor: Intel Core i7 14700F (61 MB cache, 20 cores, up to 5.4 GHz Turbo)
-
Videocard: NVIDIA GeForce RTX 4070 SUPER 12GB GDDR6X
-
Memory: 32 GB: 2 x 16 GB, DDR5, 5600 MT/s
-
Harddrive: 2 TB, M.2, PCIe NVMe, SSD
I don't know if I'll ever upgrade. Is 500W good enough?
PC Part Picker can give you an estimate of power usage. I just plugged in what you gave us + a random mobo and AIO and it seems to think 500W is probably too low, but if you're buying anything pre-assembled it's most likely calibrated correctly. Maybe they're undervolting the GPU or the CPU, or they just have a less thirsty GPU than the random 12GB 4070 Super I picked but idk.
My instinct is that if it's being sold as a complete system you don't need to worry about it.
