Dell puts a 460W power supply in their G5 Gaming PC with an RTX 2080 and i9-9900k

Ive been browsing through a review of the Dell G5 while window shopping, and when I was reading through one review site, they said that their highest config G5 system only has a 460W power supply

I went to dells website to really see if this was true, and it was 

How is Dell insuring that these things wont blow up under load with such a small power supply

Technically the combined tdp of the 2080 and 9900k is 320 watts. That is super weird and possibly unsafe? Also to be honest is decently overpriced too. I mean 64GB is unnecessary and all, but what the hell is Dell thinking. On a machine this price, from just this screenshot it seems they’ve cut a number of corners while keeping the computer overpriced for its specs. Considering that’s the price when it’s 600$ on sale, it’s kind of ridiculous.

See my signature below. Overclocked i7, titan xp, only pulls 400 watts in a synthetic load maxed out (and that's measured at the wall, not component side). Not unusual that a 460 watt PSU can handle these components. If it's decently efficient, the fan won't even have to work too hard to keep things under control.

Good 460 > shit higher wattage

 

 

Not saying it's good or adequate, just that it may not be necessary to have a bigger PSU.

That would only be for those two components, after adding a motherboard, the 64gb of ram, hard drives, etc It would come very close to the 460w listed

I know delta is a good PSU maker, but im not sure if they are using Delta in the PC

I guess if Dell is really using a high quality power supply they could get away with it

until someone decides to OC their 2080

Please don't tell me that you are gullible enough to believe in any "PSU calculator". For actual power draw measurements, you can check reviews.

Here is the wall power draw with a 7820X. The system will draw about 10% on the DC side from the PSU, so the power draw should be about 350W.

Also, if the user manages to overload the PSU, it will shut down safely. This happens with all somewhat decent PSUs, and many crappy ones as well.

It's 460w gold or platinum efficiency... I think it has proprietary connector and most likely it's 12v only power supply so all 460w are available for cpu and video card.

 

I suspect the motherboard's bios is configured with the power limits for cpu lower than what you'd have on standard motherboards (considering there doesn't seem to be heatsinks on the vrm) so you won't be able to overclock the 9900k to extremes or sustain high power consumption for long periods.

Also, as a high quality oem psu, most likely there's something like 10-15% reserves or can sustain some extra 50w for a few seconds at a time if needed without damage.

Theres no mention of any 80+ certification but I guess the fact that the 9900k is bios limited that will ensure it wont blow up

If they're going to sell it in California, it has to be at least Gold.

 

It's a Dell proprietary, ATX12V only PSU.  It's also a proprietary form factor.
