CamelCamelCamel.
Anyone know if a 1000w will be near this price?
Google knows
I have this. Highly recommended.
So quiet and reliable my entire household uses RMx. Oldest one at 7 years iirc.
Yep. I'll only ever buy this psu rmx family probably for ever.
Worth noting that there is a new PSU standard, ATX 3.0. Should consider if doing a new build.
I grabbed this, however, I won't be doing a top tier build. Hoping to get a 6800xt or whatever equivalent is with the 7xxx series. But that's a long shot.
For 99% it won't make a big difference. From memory the big changes were power spike handling, efficiency and faster wake times.
are the cables/pin count different now?
IMO right now is not a good time to switch to ATX 3.0 and I just ordered RM850x for my next build.
Current ATX 3.0 PSUs are not 100% ready.
A lot of them are claiming "ATX 3.0 ready", "ATX 3.0 compatible" .etc and it's very confusing. For example, this TT 750W PSU claims it's compatible but it can only output 300W via its 12vhpwr port. Similarly, not all "ATX 3.0 " can guarantee outputting 600w via 12vhpwr AND meet the power excursion requirement. So I suspect lots of the current products just provide an extra 12vhpwr port and claim they are "ATX 3.0 compatible".
Too expensive.
Current ATX 3.0 PSUs are all over $300. Based on the standard, PSU > 450w & 12vhpwr connector needs to reach 200% of rated size for 100us. So a 1000w ATX 3.0 PSU needs to be able to output 2000w for 100us/1800w for 1ms/1600w for 100ms. Basically they need similar grade components as a 1600w ATX 2.0 PSU.
Fewer choices.
Not many reputable brands have released their products (e.g. Corsair, Super Flower). Seasonic has released Vertex line but they haven't put it to Focus line.
Current gen CPU and GPUs are not that power hungry. Maybe 5090 will need 600w but that would be two years later and by that time ATX 3.0 PSUs should become mainstream and more affordable.
Therefore I think right now is not ideal to spend over $300 on a high wattage PSU and wish it could be future proof. Instead, spending $200 on a good 850w or 1000w PSU with a 12vhpwr cable for the new build, and upgrade to a "real" ATX 3.0 PSU when the time comes might be a better choice.
Yikes, thanks for doing the research and writing that out.
I thought that too but why drop $270 on ATX 2.0 now only to have to buy ATX3.0 in 2 or 3 more years. Just pay the premium and be happy.
I do agree better models may come out though
PSU price has really gone up since last year
Cuz some hungry new GPUs?
Corsair's quality control is good.
MLFans are more noisy under medium to high loads?
Just bought a white one of these last week after my Gigabyte 750W unit died on me. Very happy with build quality, cabling and quietness under load.
How did you know?
I’ve only had one die, in 30 years. And wow, it let me know. Flash-pop-smoke. Never trusted cheap PSUs since
I wasn't really sure to be honest as the power supply passed the paper clip test and all the voltages measured OK with my multimeter, it just didn't come to life when I plugged it in to my motherboard and hit the power button. As such, I actually thought it was the motherboard, but that was strange too because the motherboard was only 1 month old.
When researching my existing PSU I found out it was one of the serial number batch that is infamous for exploding, so I decided to just change the PSU regardless and hopefully that would fix it, which it thankfully did!
Have one and it's simply excellent. I spent the extra bucks due to, as far as I can remember, high quality Japanese capacitors and the fan stops below a certain temp to make it super silent.
Paid retail AUD215 a year ago as needed urgently, so 189 I reckon is not bad.
PSA: Always use the supplied cables, the cables between different PSUs are not compatible even though it fits and may damage components.
PSA2: Most Corsair PSU series use the same compatible, interchangable cables.
I would still triple check if using cables from a different series though, and definitely don't swap cables between brands.
My brother learnt that cruel mistake with a “desktop” external HDD, back in the 3-4 pin power-plug days. Fried. Expensive delidding from PAYAM to get a decade of kids/family photos back.
was much cheaper before
So were houses.
Can someone please tell me why I should buy a fully modular PSU over a semi modular PSU?
either way you still need to use the motherboard and cpu cables
Can use custom cables. Looks neater.
Just use PSU sleeved Cable Extension cables
Not the same at all.
I've said this before, and I guess I'll say it again here: If you ever feel the need to justify a purchase, you most likely don't need it or at the very least won't put it to good use.
I'm pretty sure this only has 2 PCIE cables so it won't work for cards that require 3.
I believe you can request more from Corsair.
Thank you!
The RM650x 650W is now $199.
Was going buy a RX1000 for $269 but ended up going for a Seasonic Vertex GX-1000 ATX3.0 for $379 to future proof system
At 40% more money?!

Nice
