Gaming PC power supply question (hexbear.net)

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...

  1. New from dell.com. Both PSU options are available.

  2. 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.

  3. 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?

No. Both the cpu and videocard each have a power draw of about 220 w. Plus the cooler, motherboard, other hardrives, fans, etc. 500w is cutting It way too close.

Even then, as other users pointed out a bad psu will fry your other componentes.

There was recently a controversy where high end Intel processors of the 13 and 14 gens have a manufacture defect that causes them to go bad in a year or so. That includes the one you like. Also the econ cores in Intel processors have been known to break shit. So i personally would avoid those.

The ryzen 7800x is about as good, and cheaper, the ryzen 7800x3d Is better but costlier.

Personally i think both of those processors are overkill for a 4070, if your intended use Is gaming.
