80 Plus Ruby Sets 96.5% Peak Efficiency Benchmark for Server Power Supplies

They're kinda late to the party tbh. Cybenetics has been hard at work with a more detailed certification process that gives buyers more up front information about efficiency and noise than whatever 80 plus has.

Is this going to be server only?

I got my titanium for a fairly good price. Now price is very high.

26 comments and no-one noticed the increased PFC requirements? This is quite important for the target market, since large companies are charged for the power factor (kW ÷ kVA) in addition to how many kWh they use. In addition to this, if there are bad harmonics going back out onto the grid, companies can be fined for disturbing the power harmonics, something PFC also helps prevent.

Why do they keep the "80 Plus" part? Instead of different suffixes like Ruby, why not 85 Plus or 90 Plus?

To obfuscate.

If they're actually running, you will never see the benefits. Even from cooling costs. At full tilt, gaining 1% on a 1kW PSU on efficiency saves you 10w per hour in heat. If it's only at 50% load, you're talking a 4-5w difference. Unless you're running entire server rooms, that amount of heat will be unnoticeable compared to HVAC running costs. It'd be the difference in heat inside a room from charging an iphone with one of those old 10w wall warts. The only way that is noticeable heating up a room is if you're in a vaccuum.

The real benefits of titanium are the low load efficiencies, which are significantly higher than Platinum, but if you're not idle most of the time, its not going to be as noticeable either, since the actual draw is so low. An LED lightbulb makes more heat in that scenario. Recouping the $100+ price difference over a platinum would take longer than any reasonable extended life expectancy of said hardware.

In DC's you pay for power - and the usage for power is usually measured at the socket where your rack starts. So if you have not one but hundreds of servers every watt you can shave off is gain in efficiency.

Like even running 8 GPU's at not stock but undervolted or lower clocks is a long term gain in efficiency and less heat and power.

So much can be saved already if we park the CPU's in servers being idle. Just saying.

Price is gonna be crazy for 1% more efficiency over Ti. Can't imagine it being worth it, diminishing return here.

Savings of $100’s of $1000’s to a $1 mill per year could be realized at this level.

Yeah, and I acknowledged that with the "unless you are running a whole server room" thing.

We're talking about desktops, where you dont have hundreds or thousands of them in a house. You have one, maybe 2, where the efficiency gain is unnoticeable.

How is this going to fit in your desktop?

A good name, since they are going to cost 1:1 to rubies

Where's Sapphire and Emerald? /s

Given how ballz expensive Titanium supplies are already, I cant imagine how much a Ruby must cost.

Expensive how? I can get a 1kW Titanium PSU for cheaper than i bought it for back in 2018. My Seasonic Ultra Prime cost 280€ ($318).
Today i see i can get FSR Hydro for 235€ or be quiet! Dark Power Pro 13 for 266€.
Yes, okay. Seasonic price has increased to 317€ (TX-1000 model).

However compared to most other PC components this is still reasonable for a high end build that crosses four figures and where RAM or mobo may cost the same, if not more. Not to mention CPU/GPU. But unlike those components, Titanium PSU's have 10-12 year warranties.
My warranty ends in 2030 and judging from my previous Corsair PSU it will likely work even past that date.

I do acknowledge that PSU prices in US seem to be bit higher. Both aforementioned models start at $290 according to PCPartPicker, and Seasonic 1kW Titanium starts at $420.

I'll wait for 80 Plus Sapphire or 80 Plus Emerald.

Everyone knows to wait for 80 Plus Diamond instead.

I read a comment somewhere ages ago that the whole 80 Plus certification is massively outdated, and I agree.

Cybenetics has been hard at work with a more detailed certification process that gives buyers more up front information about efficiency and noise than whatever 80 plus has.

Indeed. Certification without noise measurement for a product with a fan (well, most of them) is pointless.

Yeah the pricing has gotten out of hand. Superflow still has affordable Leadex Titanium PSUs though but I think they are the only one. $200 for 1,000w titanium as compared to $550 Seasonic Prime.

Not sure where you took the $550 price, but like i pointed out it's cheaper and even cheaper in EU. ($290 for FSP/be quiet! and $360 for Seasonic).

Since the article didn't quite spell it out. 80 PLUS Ruby is only for data centers atm.
