SilverStone today introduced the HELA 2050 fully modular ATX power supply. This absolute unit packs over 2 kW of juice in a box that's just 18 cm in length. Typically, PSUs over 1600 W are over 20 cm in length. The 18 cm length makes this PSU fit for even mid-towers, if you've figured out what to do with that much power—a record-chasing overclock on both your swanky new Core i9-12900K plus an equally maxed out RTX 3090 or RX 6900 XT. The PSU has been certified Cybenetics Platinum for its main function, and Cybenetics Standard+ for acoustics.

The SilverStone HELA 2050 W uses a 135 mm double ball-bearing fan, and can be made to run completely fanless up to 820 W load. Connectors include one 24-pin ATX, two 4+4 pin EPS, one 12-pin Molex microfit 3.0 connector that you can directly plug into NVIDIA RTX 30-series Founders Edition graphics cards, eighteen 6+2 pin PCIe power connectors, twelve SATA power, three 4-pin Molex, and a Berg. Under the hood, the HELA 2050 uses a single 170-Amp +12 V rail (enough juice to crank a truck). You also get active PFC, DC-to-DC switching (up to 120 W on the 5 V and 3.3 V rails), and most common electrical protections. Available toward late-December 2021, the SilverStone HELA 2050 is expected to be priced at USD $599.

I cant see one of these in a mid-tower case, just not enough room to cram everything this psu can handle. But its a good talking point.

Since when is 170A enough to crank a truck?
Not even an American truck which is really a pickup and requires at least 300A.

good on them using cybenetics instead of 80plus, wish more vendors did this.

Only 22 amps on the 5 volt line is very poor.
You do know that high-powered USB ports or USB-PD ports (20 W or 60 W), use 12 V rail and switching hardware on the motherboard, right?

i suggest you look at other PSUs, not matter what their rated wattage output; none have more than 25 amps of either 3.3 or 5v ei:

I wouldn't be surprised if it actually could do more on 5V, but they limited it so it gets better vreg/ripple numbers in reviews.

A 2050W power supply. Brilliant.

Are these even usable in the USA? This guy is trying to pull 2350 watts, and he has problems:

Does it still run fanless up to 820W in the US or is that reduced to 660W?

Might be interesting for a quiet gaming PSU assuming it doesnt have crazy coil whine like the NJ700 or Prime TX-700.

Coil whine is a lottery. Nothing to do with that. Just RMA the units till you get a good one, let them choke on their crap. Normally investigations are started basing on RMA numbers and then a ticket occurs and the engineer looks at it, but as these are very small companies with limited experience unlike seasoned titans like LG, Samsung, Sony etc who tend to spank their OEM partners if something happens. I am afraid they do not have such refined mechanism. The topic still doesn't get enough attention too, including with graphics cards whose VRM design is a joke working on the limits, thus people have started to accept coil whine a norm, yet it is totally not... good that Amazon game came out and burned few cards proving what kind of gimped designs we are being fed, despite the huge device cost. For the price of 3090 we should be sold Kingpin or HOF design class cards a norm in VRM design. Due to normally sized VRM nature they do not exhibit such loud VRM noise as the load on coils is much less and they are less stressed. The fun fact, the BOM cost between the reference and such custom isn't that large, it is all marketing.

The manual doesn't state differences in that fan mode department, another argument why the all certification stuff is pure bullshit. It states forced air cooling and semi FAN mode with MCU and that is it. Cybenetics that or this. It is not readable, it is not very professional, despite how one tried to look it like it should be, it looks like made by a student in the end of the day, of course during the last night before deadline. The manual should contain it all, like most products actually had during cold war era. Schematics, specs, part list and all curves in all modes, like you mentioned need. You sample any kind of stickers on it, what does it mean that units with the same sticker set vary a lot and you still have to search some obscure info to decide what to buy. Those standards are made to make the purchase easier, yes? But it is not. Cybenetics Standard+ for acoustics, like it does mean something.

You cannot blame Silverstone for that tho, Seasonic even doesn't provide also anything more, I would say even less, albeit their product page shows Fan operation graph as a PR picture.

That's 110w. Enough for ten hard drives.

What do you run on the 5v line that is so demanding?
ARGB runs off 5V, and while i think it's well within safe limits for the PSU it can certainly add up

It's only used once, as a meaningful word?

Does it run directly from the psu 5v or is it off of the motherboard 12v, lowered to 5v?
Directly from 5V, in most cases. Running ARGB off the motherboard is extremely uncommon and only done in very basic builds... to run more than one or two ARGB devices always requires an externally powered ARGB controller

what's that got to do with this PSU?

Silverstone is the manufacturer of this PSU, not this "Hella".


...unless, you mean that "Hella Powerful, Hella Compact" might be taken as an association with this company, then I agree.
Besides, that title isn't that good anyway.
