Building a high-end AI workstation with several powerful GPUs can create a serious power problem. SilverStone now has an answer with its new SilverStone HELA 3000Rz, a huge 3000W power supply designed for demanding AI inferencing systems.

The new PSU follows the standard ATX PS/2 form factor, so it can fit into systems designed around the common ATX PSU layout. Its main goal is to provide enough power for workstations running up to four high-end graphics cards.

3000W of Continuous Power

The biggest feature of the HELA 3000Rz is its 3000W continuous power output. That gives it enough headroom for systems where multiple GPUs are working at the same time.

SilverStone rates the unit at 80 Plus Platinum efficiency when operating from 230V AC. The PSU also uses a single +12V rail capable of delivering up to 250A, making it suitable for hardware that can place a very heavy load on the power supply.

For AI workstation users, this kind of capacity is important because modern high-end GPUs can demand a lot of power, especially during sustained workloads.

Four 600W GPU Power Connectors

SilverStone has equipped the HELA 3000Rz with a large selection of power connectors. The PSU includes four 12V-2×6 connectors, with each capable of delivering up to 600W.

The full connector setup includes:

• 1 x 24-pin ATX
• 4 x 12V-2×6, up to 600W each
• 4 x 4+4-pin EPS
• 8 x 6+2-pin PCIe
• 8 x SATA
• 4 x Molex

This gives builders plenty of options when putting together a workstation with multiple GPUs, CPUs, storage drives and other hardware.

Built With Protection Features

A 3000W PSU needs to deal with very high electrical loads, so SilverStone has included several standard protection features.

The HELA 3000Rz supports protection against over-voltage, under-voltage, overload, overheating and short circuits. It also features active PFC for improved power handling.

Cooling is handled by a 140mm dual ball-bearing fan, which is designed to keep the PSU operating under heavy loads.

HELA 3000Rz Price and Availability

SilverStone has priced the HELA 3000Rz at $819.99 in the US. The North American version also comes with a C19 to NEMA 6-20 power cord, allowing the PSU to draw up to 3.75 kVA from the wall.

With its 3000W output and four high-power 12V-2×6 connections, the HELA 3000Rz is clearly aimed at users building serious AI workstations rather than regular desktop PCs.

For a four-GPU system, having this much power available can make the PSU one less limitation to worry about.

Seasonic has become the first manufacturer to achieve 80 Plus Ruby certification for an ATX power supply tested at 115V. The milestone was awarded to the company’s Prime Enterprise RX‑1600, a PSU designed for desktops, workstations and AI systems.

Seasonic CEO Walter Sun noted that the brand has a long history with 80 Plus benchmarks, having certified the first 80 Plus PSU in 2005 with the SS‑400HT and later securing the first 80 Plus Gold rating in 2008. The company doesn’t seem to be resting on its laurels either, with Ruby certification at 115V marking another step forward for its engineering team.

Administered by CLEAResult, Ruby is the newest and most demanding tier in the 80 Plus programme. To pass at 115V, a unit must achieve 85% efficiency at 5% load, 91% at 10% load, 93% at 20% load, 95% at 50% load and 91% at 100% load, alongside a power factor of at least 0.95 at 20% load. The inclusion of 5% and 10% low‑load requirements targets idle system behaviour, where most setups spend the majority of their time.

Efficiency gains at this level may appear small on paper, but they require significant development work. For a global brand like Seasonic, even minor improvements can translate into meaningful savings at scale.

KitGuru says: Seasonic continues to lead the pack when it comes to power supplies. What efficiency rating do you typically go for when picking a new PSU for a build?

As you would expect from a flagship power supply, this unit is fully modular and it does have a Zero-RPM mode to keep noise levels to a minimum at low to moderate workloads.

With 1650W of capacity, the new MaxTytan II is well suited towards ultra high-end gaming builds, as well as powerful workstations. It is all backed by a lengthy 13-year warranty too.

KitGuru says: Typically in the tech world, we see painfully short warranty windows. That is not the case with Enermax and this new power supply.

A good power supply is the heart of any PC. Typically for a budget build, you will want one with at least an 80Plus Bronze efficiency rating. GameMax is introducing its latest line of affordable bronze-rated PSUs this week, which are fully compliant with the ATX 3.1 specification.

While cheap with prices starting at just $49.99, these PSUs are not modular, so you will have to deal with hiding away some extra or unnecessary cables. If you are running a current-gen RTX graphics card, then you'll also want to opt for a 750W or 850W model, as these are the only ones featuring native 12V‑2×6 connectors. Internally, all of the new MAX PB PSUs use 100% Japanese capacitors from Rubycon, Nippon‑Chemicon and Nichicon, alongside pure copper output cables to improve conductivity and reduce power loss under sustained load.

Cooling is handled by a hydraulic‑bearing fan rated for 40,000 hours at 40°C, with smart temperature control to keep noise levels low. The MAX PB PSUs also include eight hardware protection features, including over‑power protection, under‑voltage protection, over‑temperature protection, over‑current protection, short‑circuit protection, no‑load protection, surge and inrush protection, and over‑voltage protection.

The GAMEMAX MAX PB‑Series will be available soon, with prices starting at $46.99 for the 550W model, rising to $49.99 for the 650W, $59.99 for the 750W, and $64.99 for the 850W. All models are backed by a 3-year warranty.

Thermaltake is launching a new programme here in the UK – TT PowerCare. Through this new initiative, ThermalTake power supply buyers in the UK will be well looked after should something ever go wrong, thanks to a swift PSU replacement service to get your system back up and running.

Starting from the 1st of March 2026, TT PowerCare will be introduced across Thermaltake’s PSU range, on top of the existing extended warranty. Under this new service, if a power supply unit is verified as faulty, Thermaltake UK will arrange a replacement within 48 working hours. On top of that, end users will no longer be required to return the faulty PSU, eliminating unnecessary downtime and logistical delays.

Speaking on the TT PowerCare programme, Thermaltake UK said: “At Thermaltake, we believe warranty support should be fast, simple, and customer-centric. With TT PowerCare, we are significantly reducing resolution time and removing friction from the RMA process, delivering peace of mind that truly matches the quality of our power supplies.”

In order to be eligible for the TT PowerCare programme, you will have to buy your TT PSU from a participating retailer. At launch, participating retailers include SCAN, AWD-IT and Falcon Computers. Additional partners may be added to the list in the future.

KitGuru Says: We don't see many initiatives like this across the UK so it is nice to see Thermaltake stepping up here. Do you think more brands should offer replacement services like this?
