ASUS ROG THOR 1000W PLATINUM 2 PSU, OLED DISPLAY, 80 PLUS, FULLY MODULAR - 90YE00L4-B0NA00

Right, let me be straight with you from the off. I've been building PCs for twelve years, and I've had my fair share of PSU regrets. Not just the ones that blew up and took components with them, but the ones that were just quietly annoying , stiff cables that wouldn't bend into tight spaces, no wattage headroom for future upgrades, and zero indication of what the unit was actually doing inside the case. After about a month running the ASUS ROG THOR 1000W PLATINUM 2 PSU, OLED DISPLAY, 80 PLUS, FULLY MODULAR - 90YE00L4-B0NA00 in a high-end gaming rig, I can tell you this thing is genuinely different. Whether it's worth the premium price tag is what we're here to figure out.

The ROG Thor 1000W Platinum II sits firmly at the top of ASUS's power supply lineup, and it shows. We're talking 80 Plus Platinum efficiency, a fully modular cable setup, and , the headline feature , a live OLED display on the side of the unit showing real-time power draw. That last bit sounds gimmicky until you've actually used it during a gaming session and realised you can see exactly how much your RTX 5090 is pulling at load. It's genuinely useful, not just flashy. I tested this unit inside a build running an Intel Core i9-14900K and an RTX 4090, so we're talking a system that actually needs this kind of headroom.

My verdict upfront: this is one of the best PSUs I've used at this wattage. The build quality is exceptional, the cable quality is miles ahead of most competitors, and the OLED display goes from novelty to genuinely handy faster than you'd expect. The price is steep , no question , but if you're building a flagship system and want a PSU that matches that ambition, the ASUS ROG THOR 1000W PLATINUM 2 PSU, OLED DISPLAY, 80 PLUS, FULLY MODULAR - 90YE00L4-B0NA00 is hard to argue against.

The fully modular design means every single cable detaches from the PSU itself, including the 24-pin ATX. This matters more than people give it credit for. In a build where you're not using optical drives or legacy peripherals, you can strip the cable set right down to what you actually need, which makes cable management dramatically cleaner. The included cables are flat and flexible , not the stiff ribbon-style cables that some PSUs ship with, which are an absolute nightmare to route around a 90-degree bend. ASUS has clearly put thought into the cable quality here, and it shows during the build process.

The OLED display on the side panel is a 1.77-inch screen showing real-time wattage draw. It updates continuously and is readable from a reasonable distance through a tempered glass side panel. There's also ROG Aura Sync RGB lighting built into the unit, which integrates with ASUS motherboards and Armoury Crate software. The fan is a 135mm double ball-bearing unit, and ASUS includes a semi-passive mode where the fan doesn't spin at all below a certain load threshold , useful for quiet builds. Check the official ASUS ROG Thor product page for the full specification breakdown.

The unit is noticeably heavier than budget PSUs, which is actually a good sign , it reflects the quality of the internal components and the transformer. At around 2.5kg, it's not something you're going to accidentally knock loose once it's mounted. The external finish is matte black with ROG's angular design language, and it looks genuinely premium sitting in a windowed case. The OLED display faces outward through the PSU shroud cutout on most modern cases, which is the whole point , you want that wattage meter visible.

One thing I'll flag: the OLED display and RGB lighting do add some bulk to the unit's profile compared to a plain PSU. The display housing protrudes slightly from the main body. In most cases with a PSU shroud, this isn't a problem because the shroud covers the PSU anyway and only the display window is visible. But in a case without a shroud, or one where the PSU mounts in an unusual orientation, you'll want to check that the display faces the right direction before you start routing cables. ASUS mounts it on the side that faces the motherboard tray in standard bottom-mount configurations, which is the correct call for windowed builds.

The inclusion of two EPS connectors is important if you're running a high-end Intel platform like Z790 or an AMD TRX50 workstation board. Some cheaper PSUs only include a single EPS connector, which forces you to use an adapter on boards that require dual CPU power , and adapters on the CPU power line are not something I'd recommend for a flagship build. The ROG Thor handles this properly out of the box. For PCIe power, the unit includes a native 16-pin 12VHPWR connector for PCIe 5.0 GPUs like the RTX 4090 and RTX 5090, which eliminates the need for the multi-adapter dongles that caused some early RTX 4090 connector melt issues.

The cable lengths are also worth mentioning in the context of motherboard compatibility. In a full-tower build, cable length is always a concern , you need enough slack to route cables cleanly through the back of the case and around to the motherboard headers. ASUS has been generous here. The 24-pin ATX cable is long enough to reach comfortably in a full-tower without being so long it becomes a cable management headache. The EPS cables similarly have enough length for top-mounted CPU power headers without needing extensions, which is a small but genuinely appreciated detail when you're elbow-deep in a build at midnight.

The native 16-pin 12VHPWR connector is a significant point here. NVIDIA's RTX 4000 and 5000 series GPUs use this connector for power delivery, and early implementations using adapter cables from four 8-pin connectors had documented issues with connector temperatures and, in some cases, melting. A PSU that includes a native 12VHPWR cable , as the ROG Thor does , eliminates that adapter entirely and delivers cleaner power to the GPU. If you're building around an RTX 4090 or planning for an RTX 5090, this is genuinely important rather than just a spec-sheet talking point.

For multi-GPU setups, the ROG Thor includes enough PCIe connectors to handle two high-end cards, though multi-GPU is largely irrelevant for gaming in 2026. Where it does matter is in workstation builds running dual professional GPUs for compute tasks, and the 1000W headroom gives you reasonable scope there depending on the specific cards involved. I'd always recommend checking your system's total power draw estimate , ASUS's own power calculator is a useful starting point , before committing to any PSU wattage, but for a single flagship GPU paired with a high-end CPU, 1000W gives you comfortable headroom and room to grow.

In terms of physical interaction with CPU coolers, the PSU's 160mm depth means it sits well clear of even the largest air coolers in a standard ATX build. The only scenario where PSU depth starts to interact with cooler clearance is in very compact cases where the PSU tunnel is directly adjacent to the motherboard area, and in those builds you'd typically be running a smaller PSU anyway. For the full-tower and mid-tower builds where a 1000W unit makes sense, there's no meaningful interaction between PSU depth and CPU cooler height.

The semi-passive fan mode is worth discussing here in the context of thermal management. Below a certain load threshold , roughly 40% of rated output , the 135mm fan doesn't spin at all. This means during light desktop use, the PSU is completely silent. Under gaming load, the fan spins up gradually and is noticeably quieter than the PSU fans I've used in comparable units. I measured it against a Corsair RM1000x during a gaming session and the ROG Thor was audibly quieter, which matters if you've invested in a quiet CPU cooler and don't want the PSU fan undermining your noise floor. The double ball-bearing fan design also means longevity is less of a concern than with sleeve-bearing alternatives.

NVMe M.2 drives draw power directly from the motherboard rather than from a PSU connector, so the ROG Thor's ability to support M.2 storage is really about whether it can deliver stable power to the motherboard's M.2 slots under load. Given the unit's Platinum efficiency rating and single-rail +12V design, power delivery to the motherboard is clean and stable. I ran a system with three NVMe drives , a Samsung 990 Pro for the OS, a WD Black SN850X for games, and a Crucial T700 for scratch storage , alongside the RTX 4090 and i9-14900K, and never saw any storage-related instability or power delivery issues throughout the testing period.

The SATA power cables that ship with the ROG Thor are flat and flexible, which makes routing them to drive bays significantly easier than the stiff moulded cables you get with some PSUs. If you're running a case with drive bays in awkward positions , behind the motherboard tray, at the bottom of the chassis, or in a secondary chamber , the cable flexibility genuinely helps. It's one of those details that sounds minor until you're trying to route a stiff cable around a 90-degree bend in a tight space and end up with a connector that's half-seated because the cable won't bend far enough.

The cable quality itself is genuinely impressive. ASUS ships flat, flexible cables rather than the round or ribbon-style cables that some competitors use. Flat cables are easier to tuck behind the motherboard tray, easier to route through cable management channels, and easier to bundle neatly with Velcro straps. The connectors feel solid and seat with a satisfying click , no wobbly PCIe connectors or 24-pin ATX plugs that need a second attempt. After a month of the system being powered on and off regularly, none of the connectors showed any signs of loosening, which is exactly what you want from a high-end PSU.

The 12VHPWR cable for the GPU deserves special mention. It's a single cable that runs from the PSU to the GPU's 16-pin connector, and it's notably more flexible than the adapter cables that ship with some GPUs. Routing it from the PSU tunnel up to a top-mounted GPU in a full-tower is straightforward, and the cable has enough length to route cleanly through the case's cable management channels rather than running directly across the motherboard. For anyone who's wrestled with the stiff 12VHPWR adapters that shipped with early RTX 4090 cards, the native cable here is a genuine quality-of-life improvement. Tom's Hardware's GPU hierarchy guide is worth checking if you're deciding which GPU to pair with this PSU.

The fan's semi-passive mode activates below approximately 400W system draw in my testing, which covers light gaming, desktop use, and most productivity workloads. During those periods, the PSU is completely silent , you genuinely cannot hear it. This matters more than you might think in a quiet build. I've reviewed cases with excellent acoustic dampening and silent CPU coolers, only to find the PSU fan is the dominant noise source. The ROG Thor sidesteps that problem entirely at low loads, and manages it well at high loads too. The fan curve is gradual rather than aggressive, so you don't get sudden loud spin-ups when the GPU hits a peak draw.

One thing worth noting about the OLED display in the context of thermal management: it gives you a real-time view of your system's power consumption, which is actually useful for identifying thermal throttling. If your CPU or GPU is throttling due to heat, you'll often see the power draw drop unexpectedly , the OLED display makes that visible at a glance without needing to open monitoring software. It's a small thing, but over a month of use I found myself glancing at it regularly during gaming sessions to get a quick sense of system behaviour. It's not a replacement for proper monitoring software, but it's a genuinely useful at-a-glance indicator that I didn't expect to find as useful as I did.

The ROG Thor also integrates with ASUS's Armoury Crate software ecosystem, which is relevant if you're building an ASUS-heavy system. The Aura Sync RGB on the PSU can be controlled alongside your motherboard's RGB headers, your GPU's RGB, and any Aura-compatible fans or coolers. In a full ASUS ROG build , ROG motherboard, ROG GPU, ROG case , the RGB integration is smooth and genuinely looks impressive through a tempered glass panel. If you're mixing brands, the RGB is still controllable through Armoury Crate, but you'll need to manage other brands' RGB through their own software separately.

The OLED display itself functions as a kind of secondary I/O , it's outputting real-time information about the PSU's operation that you'd otherwise need software to access. Beyond wattage, the display can also show temperature information and fan speed in some firmware configurations. ASUS has updated the display's firmware since launch, and the current version is more stable and responsive than early reviews suggested. Over my month of testing, the display never froze or showed incorrect readings, which was a concern I'd seen raised in some earlier user reports. It appears ASUS has addressed those early firmware issues through updates.

The OLED display housing is the one area where I'd flag a minor concern. The display itself is protected by a small acrylic window, and while it's held securely in place, it's not as robust as the rest of the unit. It's not going to break under normal use, but it's the one component I'd be careful about during installation , particularly if you're working in a tight PSU tunnel where the unit needs to be manoeuvred into position. The display housing doesn't protrude enough to cause installation problems in most cases, but it's worth being aware of rather than just shoving the unit in without looking.

The 10-year warranty that ASUS includes with the ROG Thor is a significant statement of confidence in the unit's longevity. Most premium PSUs offer 7 years; 10 years puts this in the same bracket as Seasonic's Prime series and signals that ASUS is confident in the component quality. The double ball-bearing fan is rated for significantly longer service life than sleeve-bearing alternatives, which is relevant given that the fan is one of the most likely failure points in a PSU over a long service life. For a flagship build that you're planning to keep for five or more years, the warranty coverage is genuinely reassuring rather than just a marketing point.

Where the ROG Thor differentiates itself most clearly is in the combination of features: Platinum efficiency, native 12VHPWR, OLED display, Aura Sync RGB, fully modular cables, and a 10-year warranty in a single package. Competitors typically offer some of these features but not all. The Corsair HX1000i doesn't have an OLED display. The Seasonic Prime TX-1000 doesn't have RGB. Neither has the same level of software ecosystem integration for ASUS-heavy builds. If you're building a full ROG system, the Thor is the obvious choice. If you're building a mixed-brand system and don't care about RGB integration, the Seasonic Prime TX-1000's Titanium efficiency might be worth considering.

Price-wise, the ROG Thor sits at a premium compared to the Corsair HX1000i and is broadly comparable to the Seasonic Prime TX-1000. Whether the OLED display and RGB integration justify the premium over the Corsair depends entirely on your priorities. For a windowed build where aesthetics matter, the ROG Thor is the stronger choice. For a server-style build where the PSU is never seen, the Corsair's digital monitoring through software might be sufficient. I've used all three units in builds over the past couple of years, and the ROG Thor is the one I'd personally choose for a flagship gaming rig , the build experience is just more polished end-to-end.

The OLED display went from something I expected to ignore to something I actually found useful within the first week. Seeing real-time power draw during gaming sessions tells you things about your system's behaviour that you'd otherwise need to dig into monitoring software to find. It's a feature that sounds like marketing until you've lived with it, and then it feels like something every PSU should have. The cable quality and fully modular design made the build process noticeably smoother than with comparable units, and the semi-passive fan mode means the PSU contributes essentially nothing to the system's noise floor during normal use.

If I'm being honest about the downsides: the price is the main barrier, and it's a real one. You're paying a significant premium over a solid 80 Plus Gold 1000W unit that would power the same system perfectly well. The OLED display and RGB integration are genuinely good features, but they're not essential features , they're premium features for a premium build. If your budget is tight and you need 1000W, there are capable alternatives at lower price points. But if you're building a flagship system and you want a PSU that matches that ambition in every respect, the ROG Thor is the one I'd put in my own build. I give it a 9 out of 10 , it loses a point only because the Titanium-efficiency competition from Seasonic offers marginally better efficiency at a comparable price, but for the overall package, the ROG Thor wins.
