Corsair Rm1000x (2024) is very solid and has plenty cables. I got it over the 850w because my 9070xt needs 3 PCIe cables.. and my corsair link also uses one so id need 4 cables and it was pretty much the same price of getting the upgrade then to buy the extra cable. Corsair also uses the new efficiency rating which is more accurate then 80plus, It has platinum and an “A” for noise. Lastly if ur into nice cables.. there great, comes with cablecombs and are not messy like some other powersupplies most of the time have. Did not regret buying it! Answer from Q-timehd on reddit.com

Looking for a good 1000w PSU - PCPartPicker
Hello, I've decided to use a 1000w PSU for an upcoming build but have had trouble choosing from a few. I've also been using the Cultist network while researching these and heard mixed opinions on it, I'd appreciate any help and other PSUs that you think would be better than these, thank you · https://pcpartpicker.com/product/RqYmP6/seasonic-vertex-gx-1000-1000-w-80-gold-certified-fully-modular-atx-power-supply...

Since these are very much personal-preference influenced items, we do not include peripherals like keyboards, mice, headsets, etc in parts lists. We strongly recommend posting a build request only if you're ready to buy now or within a week or two at most. Part sales regularly rotate, and a part list today can quickly become out of date.

The best white PSU for 2025-2026
Hi there Thank you for using our list From here i would choose gigabyte aorus elite or lian li gold Edge. The aorus elite didnt have a quite proper review until now so we couldnt really confirm the tiering on it. Lian Li EDGE 1000 Gold comes with a USB/FAN hub btw. RMe is B+ due fan type.

People also ask

Can a 1000W power supply be too much power?

A 1000W PSU isn't too much power if you have high-end components. Modern PSUs are efficient across various loads, with most maintaining 80%+ efficiency even at 20% load. The only downside is higher initial cost, but the headroom provides stability and supports future upgrades without needing a new PSU.

Does a 1000W PSU always draw 1000W power?

No, a 1000W PSU only draws as much power as your components need. During typical gaming, it might draw 400-600W, and for desktop use, often just 100-200W. The 1000W rating is the maximum it can safely deliver when needed, not constant consumption.

What GPU needs a 1000W power supply?

The RTX 5090 officially recommends 1000W minimum, while the RTX 4090 suggests 850-1000W for optimal performance. Professional GPUs like the RTX 6000 Ada also benefit from 1000W PSUs. Multi-GPU configurations and systems with extensive overclocking typically need 1000W+ to ensure stable operation.

r/buildapc on Reddit: Chosing a 1000W PSU in 2026 - Hesitation between a few models
May 26, 2026 -

Hi guys, gonna try to keep it short :

I am in the market for a new PSU because I decided 11 years old Corsair was to be retired soon. In anticipation for my next "big upgrade" going on AM5 and a 9070XT / 5070Ti.
Anyway, I'd like to get a 1000W psu, but I'm torn between a few choices :

AsRock Steel Legend SL-1000P looks so promising and is a fair bit cheaper than the other choices.

The PSU tier list rates it A+ but the guys at Hardware busters are scaring me about the OCP features with their "dealbreaker" judgement on it.
It's annoying cause it's such a good Price compared to the other choices I have.
Is this paranoia ? Or is it really something to be concerned about ? I mean, the OCP are there, just set "high". Is this just something to care about in "test lab" condition ?

Otherwise, I gotta go with a C1000 Gold 3.1 from NZXT, but the platform is a bit more dated since it's a 2023 design.

Or a RM1000X but then again, price is a bit higher than the Steel Legend.

Any input on the subject ?

EDIT :
I dont' really wanna discuss the wattage choice. I'd rather have "more" than needed, and run the PSU at a lower load.

Also I'm in for 10 years+ of usage, like the last two PSU I had so yeah, I'm oversizing it just in case my "next next" build asks for more.

Instead of buying a new PSU every build I do.

Best Power Supply for Gaming PC 2026: 5 Quiet ATX 3.1 Picks | isitBOTTLENECKED Blog
January 8, 2026 - These five picks cover the range most gaming builds actually need: 850W for current mid-to-high-end setups, 1000W if you're running a flagship GPU or planning upgrades, and a budget option that doesn't cut corners on the spec. All ATX 3.x, all properly sized for GPU spike behavior. If you want a specific recommendation, drop your CPU, GPU, and case below. Is 850W enough for a gaming PC in 2026? For most single-GPU builds, yes. The edge case is a high-TDP GPU paired with a power-hungry CPU, both running hard at the same time — that's where 850W starts cutting it close on spikes.

An 850W PSU is usually enough for most high-end gaming PCs, giving you enough power for strong GPUs (like the RTX 4080/4090) and CPUs. However, if you're using the very best components (like an RTX 4090 with an Intel i9 or AMD Ryzen 9) and want extra future-proofing, a 1000W PSU is a safer choice.

3 weeks ago - Select a PSU that is appropriate to your CPU and GPU, with a little room for overclocking or upgrades as requirements increase, including power spikes. Current high-end gaming rigs will work fine on a 650W to 850W power supply. With a flagship GPU and a high-count-core CPU with lots of extras, 1000W-1200W can be rationalized.

here's my build. It's strickly for gaming. I've purchased everything but the cpu and psu. Any suggestions on a decent power suppy? ive been using that SPL list and finally switched to the phantom (A rated) but some bad reviews on newegg. But it seems every PSU I find for like sub $200 that is 1000w seem to have several bad reviews on them. started with montech century then the lian li edge but read several "stop working after x months" posts and that just scares me off after spending so much on parts.

r/buildapc on Reddit: The best white PSU for 2025-2026
January 1, 2026 -

Greetings all,

I have to say that finding a good white PSU is so insanely hard compared to a black one. Thats why i need help to pick one.

Corsair RM750x Shift 750W (White) -> 172 euros

Probably the absolute best out of there, but ffs 172 euros??? For a 750W? come on that is outrageous.

Corsair RM850e ATX3.1 850W (White) -> 143 euros

This is the Rme not Rmx. A lot of people have reported coil whine and its a B+ only in the SPL's tier list. A choice to avoid i think.

Gigabyte Aorus Elite P850W (White) -> 135 euros.

When you try to search this, people keep shitting on gigabyte for that one series of psu that caught on fire/exploded and i agree that gigabyte is a shit company and their psus suck EXCEPT for the Aorus Elite series.

Its literally an A- on SPL's tier list. There is 0 coil whine, the fan sound is quiet. I'm guessing all the protection it has in place are decent since they put it in A-. Honestly dumbfounded why people arent picking this.

Seasonic Focus GX ATX3.1 2024 750W (White) -> 140 euros.

People say Seasonic is the best of the best and stuff. Sure this might be for the old GX, but i have read a lot of stuff and found many bad reviews for this new GX of seasonic.

Coil whine, some dead on arrival, some broken after 2 months. Even after all of that its a A- on SPL list. Insane.

Lian Li Edge Gold 1000W (White) -> 140 euros

Holy 140 euros for 1000W? Honestly this looks good all around and its an A on SPL's list. Most reviews i have seen (not a lot though) say that its perfectly fine. The only bad thing i could find is from one youtube comment that it said it came dead on arrival.

The only thing i dont like its the L shape honestly, seems like a pain.

You have some other options like the MSI Mag (White) but all of them are not at A tier and i found a lot of negative stuff for them.

Out of the options above what should i choose? What White PSU do you have? for how long and has it shown any problems?
