Is 500Watts enough for this pre-assembled computer?

[jippa_lippa]

I know...purchasing a pre-made computer is not ideal in normal circumstances, but we're not in normal circumstances these days and I recently eyed a decent HP pre-made computer in a store near me.

The computer has only a 20% increase in price compared to the components added ne by one, and for the tragic situation we're in, it's not bad.

 

This machine has such features:

• Intel Core i7-11700 (not the K version)
• 32 GB DDR4-2933 MHz RAM (2 x 16 GB)
• 1 TB PCIe® NVMe™ M.2 SSD
• NVIDIA® GeForce RTX™ 3060 Ti (8 GB GDDR6 dedicated)
• DVD Reader
• 500W Power Supply

I'm a bit concerned about the power supply situation though...
I'd use the thread opened on this forum to calculate the wattage, but it seems to be stuck at the 10th generation.
 

If I had to make a computer on my own I'd use a 600watt supply (as recommended also for the 3060TI), but I don't see why they'd put an inadequate power supply inside the computer.
In the absolute worst case scenario I can replace the power supply, but do you think 500 watt is enough for the configuration?

 

With regards to buying a pre-made computer, the situation in my country seems to be even more tragic than in North America.
I preordered my GPU (3060TI) a minute after launch and after 8 months I still can't get it and I'll have to wait at least 3 more months, meanwhile I'm afraid the rest of the components would become much more expensive and hard to find.

Thanks for the help.

You mean besides to make more money?

Well...yes.
But I'd at least put in the bare minimum.

Isn't 650W the bare minimum for my configuration?

500w supply if it is actually 500w should be fine.

The 3060ti is a 200w card, and the 11700 won't pull more than 200w at full load (probably), less if it follows intel power limit spec. That leaves 100w presuming it's rated appropriately for everything else.

 

The 11700K pulls 273 total system power (no GPU) and that's with higher TDP (spec).

But it's all presuming it's a decent 500w unit. I'd get a decent 750w unit myself and then not worry about it at all.

I think the 500W would be well out of its efficiency sweet spot though.

 

What I would do is buy the system, swap out the 500W PSU for a 600W or higher unit you know is reputable, and unless you really need the 32GB of RAM, sell it also and replace with 2x8GB sticks to help offset the cost of the new PSU.

I think 2x16 is worth it if they are dual rank. There's a small bump there in performance. Go into BIOS and make sure it's set to Gear 1 also.

Honestly I'd just get a better PSU for insurance and then go in there and possibly upgrade the CPU cooler, and then do a better job of cable management that I'm sure is nonexistent. Maybe add a 120mm fan or two in the right spots.

I honestly thought of that, but I'm afraid I'd void the warranty.
 

I also think I could get the original power supply in in the case (god forbid) that I'd need to send it back.

500w is enough. In prebuilds the cpu works within the Intel specs and will not succeed 105w.

GPUs in prebuilds have lower tdp and consumes less than branded GPUs

 

What prebuild is it exactly? Most prebuilds use a 12v only PSU with 12vSB. You can't replace it for a regular ATX specificated PSU.
