Operating a 832W device with an 850W power supply?
Operating a 832W device with an 850W power supply?
How severe is it to operate a PC near its power supply limits?
I've replaced all my old components with a new case and added some upgrades. The total system load appears around 830W, thanks to online power supply calculators and some aggressive overclocking on everything.
Is it really an issue to run so close to its maximum wattage?
Here’s the full system setup:
EVGA 152-HR-E979-KR - EATX
4790k @4.9ghz (water-cooled)
2x GTX 780 overclocked slightly (water-cooled)
GSkill Ram 32GB @ 2400mhz DDR3 (water-cooled)
DDC 3.2 Pump 18v
PCI raid controller (not yet purchased)
8x 3GB 3.5" WD red raid 10
4x 500gb SSD raid 0
1 x 2tb 2.5" sed backup
I’m considering these choices:
- Stick with the PSU and see if it holds. (Is this safe?)
- Upgrade to a PSU and purchase a Molex unit for all the drives and the pump. (Definitely if I could afford it.)
Appreciate any advice!
you should be ok with that psu. it is pretty good quality. here is johny's review of it if you wish to read it

knowing you'll stay below 700w even at high loads, i'd have no concerns using the psu for the system.
you're not at 800+ watts. those calculators usually give wrong numbers. add up the values—780 is around 250w each, so about 500w. a 4790k is 88w, maybe 110 or more overclocked, so roughly 125w just to be safe.
you're at 625w, which is a rough estimate. the rest could add another 100w. that makes a high guess of around 725w, about 85% of the psu's capacity. this falls within the safe operating range for a good unit. the missing part is the psu model. if it's a low-quality one, upgrading would help. if it's already solid, you're fine as is.
what psu do you currently have?
Haha yeah would have been helpful to link my PSU

No idea if its decent or not.
Math Geek:
you're not quite hitting 800+ watts. those calculators usually give a big mistake. just add up the numbers—each 780 is around 250w, so about 500w total. The 4790k is roughly 88w, maybe a bit overclocked at 110w or more, or just about 125w for extra safety.
You're at 625w, which is a rough estimate. The rest of the components might add another 100w. That brings the total to around 725w, which is close to 85% of the PSU's capacity. This falls within the safe operating range for a good unit. The missing piece here is the PSU model.
If your PSU is low quality, upgrading would make sense. If it's solid, you're good to stay where you are.

your power rating isn't quite there. those calculators usually give a big error. just add some figures—each 780 is around 250w, so 500w total. The 4790k is about 88w, maybe 110 or more if it's overclocked, so roughly 125w just to be safe.

This one here. And it's unlikely all components will load at once, especially over time. as before, let's know the PSU you're using.
it's always wise to have a PSU ready for tough situations. it's not very reassuring to think your PSU might struggle under heavy demand.
also, that's why all the figures seem like overestimates.
I'm sure a tough test might push it higher, but I still question if it would reach those high values. Are you recommending more power?
I've never used this GPU before, so if you have any numbers to share, please adjust me. I think a small overclock could really boost the usage. I didn't check specific benchmarks just the OEM TDP info.
The review highlights that the system's performance is adequate despite its components, as the total power draw remains within acceptable limits even with added loads. There are no clear signs of power-related issues.
