Finding the right PSU is one of those decisions that most builders underestimate. Get it wrong and you are looking at instability, coil whine, or worse. Get it right and you will never think about it again. The good news is that the Best ASUS Power Supplies: Top Picks for 2023 cover a genuinely wide range of budgets and use cases, from sub-£100 no-frills units to premium Platinum-rated showpieces with OLED displays. ASUS has three distinct lines: ROG for enthusiasts, TUF Gaming for builders who want quality without the premium price tag, and Prime for those who just want a reliable, efficient PSU and nothing more. We have ranked all nine models honestly, including where they fall short.
The ROG Strix 750W Gold Aura Edition is the one to beat in this roundup. It sits at the top of the Best ASUS Power Supplies: Top Picks for 2023 list for good reason. You get 80 Plus Gold efficiency, full ATX 3.0 compatibility for modern GPU transient loads, and PCIe Gen 5.0 readiness, so it is properly future-proofed for current and upcoming graphics cards.
The Axial-tech fan is the same design ASUS uses in its GPU coolers. It is noticeably quieter than generic PSU fans, and the dual ball bearing means it will last the distance. Aura Sync RGB is a nice touch if your build has a windowed side panel, though it is not going to make or break a purchasing decision. What will is the 10-year warranty. That is a serious commitment from ASUS and reflects genuine confidence in the unit's longevity.
At 750W, this suits the vast majority of gaming builds. An RTX 4070 Ti paired with a Ryzen 7 or Core i7 sits comfortably within its limits. If you are running an RTX 4090, step up. But for everyone else, this is the sweet spot. Cable management is clean thanks to full modularity, and the build quality feels premium without being overengineered.
The price is higher than the TUF and Prime alternatives, but the combination of features, warranty, and brand-tier justifies it for anyone building a proper gaming rig.
Pros
10-year warranty is class-leading
Axial-tech fan runs very quietly under load
Aura Sync RGB integrates well with ASUS ecosystems
Here is the thing: most PSU roundups ignore small form factor builders entirely. The ROG Loki SFX L 850W fixes that. It is the standout pick for anyone building in an SFX or SFX-L compatible case, and it brings specs that embarrass a lot of full-size ATX units.
Platinum efficiency means it wastes less power as heat, which matters enormously in compact cases where thermal management is already tight. Lambda A certification from Cybenetics confirms low noise output, a real bonus when your PSU is sitting closer to your ears in a small chassis. The 120mm ARGB fan is larger than most SFX units manage, which helps keep temperatures in check without spinning up aggressively.
ATX 3.0 compatibility and PCIe 5.0 readiness mean it handles the power delivery demands of current-gen GPUs without complaint. At 850W in an SFX-L form factor, it has enough headroom for a high-end GPU and a power-hungry CPU in a compact build. Aura Sync works here too, though in a small case you may not see much of the fan anyway.
The price is reasonable given what you are getting. SFX Platinum units from other brands often cost more for less. The only honest caveat: if you are building a standard ATX case, there is no reason to choose this over the ROG Strix or TUF Gaming options.
Pros
80 Plus Platinum efficiency, better than Gold alternatives
Lambda A certified for low acoustic noise
SFX-L form factor opens up compact build options
850W gives solid headroom for high-end components
ATX 3.0 compatible
Cons
No benefit for standard ATX case builders
SFX cables can be harder to source if replacements are needed
Premium price for the wattage compared to ATX alternatives
The TUF Gaming 1000W Gold is the sensible choice for anyone running a high-end GPU like an RTX 4080 or 4090 who does not want to pay ROG THOR prices. It hits ATX 3.1 compatibility, which is the latest standard and handles transient power spikes better than ATX 3.0. That matters for cards like the RTX 4090 that can spike well above their rated TDP momentarily.
Military-grade components and PCB coating give it genuine durability credentials. The coating protects against humidity and dust ingress, useful if your setup is not in a climate-controlled environment. The Axial-tech fan keeps noise down, and the dual ball bearing design means it will not develop a rattle after a few years of use.
At 1000W, this is proper territory for demanding gaming rigs. Pair it with an RTX 4090 and a Core i9 or Ryzen 9 and you still have headroom to spare. The 10-year warranty is the same as the ROG Strix, which is impressive at this price point. Fully modular means you are not wrestling with unused cables stuffed behind the motherboard tray.
The TUF aesthetic is understated. No RGB, no OLED display. Just a well-built, efficient PSU that gets on with the job. For builders who prioritise performance over presentation, that is exactly right.
Pros
ATX 3.1 is the latest standard, future-proofed
Military-grade components and PCB coating
1000W suits the most demanding single-GPU builds
10-year warranty matches the premium ROG tier
Quieter than many 1000W competitors
Cons
No RGB for those who want a lit-up build
Slightly more expensive than the Prime 850W for less wattage-per-pound
If you are building your first proper gaming PC and want something that gives you plenty of headroom without overcomplicating things, the Prime 850W Gold is a smart pick. It is part of the Best ASUS Power Supplies: Top Picks for 2023 selection specifically because it strips away everything non-essential and delivers a clean, reliable foundation.
850W is a comfortable amount of power for a mid-range to high-end build. You are not going to be caught short by an RTX 4070 or 4080, and there is room to upgrade later without replacing the PSU. ATX 3.0 compatibility and PCIe 5.0 support mean it handles current GPU power delivery requirements properly.
The double ball bearing fan is quiet and long-lasting. The fully modular design makes first-time cable management much less stressful. You only plug in what you need, which keeps the inside of your case tidy and improves airflow. For a beginner, that is a genuine quality-of-life improvement.
There is no RGB, no OLED, no fancy extras. And honestly, for a first build, that is fine. You want the PSU to work reliably and stay out of the way. This one does exactly that. The price sits just above £100, which is fair for 850W of Gold-certified, fully modular power.
The TUF Gaming 750W Gold sits right at the £100 mark and offers something the Prime range cannot: military-grade components and PCB coating at a price that is still accessible. It is the pick for builders who want a step up from entry-level without breaking the budget.
ATX 3.1 compatibility is a genuine advantage here. It is a newer standard than ATX 3.0 and handles the kind of instantaneous power spikes that modern GPUs produce more effectively. For a 750W unit, that is reassuring if you are pairing it with something like an RTX 4070 Ti. The Axial-tech fan keeps things quiet, and the dual ball bearing design adds longevity.
PCB coating protects the internals from moisture and dust, which is a detail you would not expect at this price. The 10-year warranty is the same as the premium ROG Strix, which says a lot about ASUS's confidence in the TUF platform. Fully modular means cable management is straightforward.
The honest limitation is wattage. At 750W, it is fine for most builds, but if you are eyeing an RTX 4080 or 4090, look at the 1000W TUF instead. For RTX 4070 and below, this is a proper bargain.
Pros
ATX 3.1 is more current than ATX 3.0
Military-grade components and PCB coating
10-year warranty at a competitive price
Axial-tech fan is noticeably quiet
Fully modular for easy cable management
Cons
750W limits options for the most power-hungry GPUs
No RGB for those who want a lit build
Sits right at £100, so not a budget pick in the traditional sense
The ROG THOR 1000W Platinum 2 is the most feature-packed PSU in this roundup. It is not cheap, but what you get for the money is genuinely impressive. The OLED display on the side of the unit shows real-time wattage draw, which is actually useful for monitoring your system's power consumption rather than just being a gimmick.
Platinum efficiency means it runs more efficiently than Gold-rated units, wasting less power as heat. Lambda A certification confirms low acoustic output. For a 1000W unit running a demanding build, that combination keeps temperatures and noise in check. The fully modular design is expected at this price, and the cable quality feels premium.
This is the PSU for builders who are spending serious money on their components and want every part of the build to reflect that. An RTX 4090 paired with a high-end CPU will sit comfortably within its limits, with headroom to spare. The ROG aesthetic is bold and the build quality is exceptional.
The price is the obvious barrier. At over £260, it costs more than some GPUs. But if you are building a flagship rig and want the best ASUS PSU available, this is it.
Look, this one is a bit different. The ROG Thor Platinum EVA Edition is a collaboration with the Evangelion franchise, and it shows. The green and purple colour scheme, the themed OLED display, and the EVA-branded aesthetics make it a collector's piece as much as a PSU. But here is the thing: the specs are genuinely excellent.
Lambda A++ certification is the highest acoustic rating Cybenetics awards. It is quieter than the standard THOR 1000W Platinum 2. Platinum efficiency, 1000W output, fully modular cabling, and an OLED display are all present. So you are not paying a premium purely for the looks. The underlying unit is top-tier.
The RGB lighting ties into the EVA theme and looks striking in a windowed case. If you are a fan of the franchise, this is an obvious choice. If you are not, the standard ROG THOR 1000W Platinum 2 makes more sense and costs slightly less.
It is a niche product, and we are honest about that. But for the right buyer, it is a brilliant combination of premium engineering and unique aesthetics. Just do not expect it to be a sensible everyday recommendation.
Pros
Lambda A++ is the highest acoustic certification available
Unique EVA Edition aesthetics for themed builds
80 Plus Platinum efficiency
OLED display with themed graphics
1000W handles any current gaming build
Cons
Niche appeal, not for everyone
Expensive for what is essentially a cosmetic upgrade over the standard THOR
The TUF Gaming 1200W Gold is for builders who genuinely need the headroom. We are talking multi-GPU setups, extreme overclocking rigs, or workstations running power-hungry components alongside a flagship GPU. For a standard gaming build, 1200W is overkill. But if you need it, this is the most sensible way to get it from ASUS.
Military-grade components and PCB coating are the same story as the 1000W TUF. The Axial-tech fan manages the thermal load quietly, which is impressive given how hard a 1200W unit can work under full load. The dual ball bearing keeps fan noise consistent over time.
At 1200W with Gold efficiency, the unit runs warm under sustained heavy load, which is expected. Platinum would be better for this wattage, but the price would jump significantly. The 10-year warranty provides reassurance for a unit that is going to be working hard. Fully modular cabling is essential at this size, and ASUS delivers it.
The price is fair for 1200W of Gold-certified, fully modular power with military-grade internals. But be honest with yourself about whether you actually need this much capacity before buying.
Pros
1200W suits the most extreme builds
Military-grade components and PCB coating
10-year warranty
Axial-tech fan keeps noise manageable
Fully modular for complex cable routing
Cons
Overkill for the vast majority of gaming builds
Gold efficiency at 1200W generates more heat than Platinum alternatives
The Prime 750W Gold is the budget pick in this roundup and the best ASUS PSU you can buy for under £100. It does not have RGB, an OLED display, or military-grade component branding. What it does have is 80 Plus Gold efficiency, full modularity, ATX 3.0 compatibility, and PCIe 5.0 support. That is a proper spec sheet for the price.
For a mid-range gaming build, this is all you need. An RTX 4070 or RTX 4060 Ti paired with a Ryzen 5 or Core i5 will sit well within its 750W capacity. The double ball bearing fan is quiet and reliable. The fully modular design makes cable management accessible even for first-time builders.
ATX 3.0 compatibility means it handles the transient power spikes that modern GPUs produce, which is important and often overlooked at this price point. PCIe 5.0 readiness means you are not buying something that will be obsolete within a generation.
The honest limitation is that it is the most basic ASUS PSU in the lineup. The build quality is fine but does not feel as premium as the TUF or ROG units. And 750W is the ceiling, so if you upgrade to a more power-hungry GPU later, you may need to replace it. But as a starting point for a sensible gaming build, it is hard to argue with the value.
Buying Guide: What to Look For in the Best ASUS Power Supplies: Top Picks for 2023
Choosing a PSU is less exciting than picking a GPU or CPU, but it is arguably more important. A dodgy or undersized PSU can damage every other component in your build. Here is what actually matters.
Wattage and headroom. A common mistake is buying exactly the wattage your components need. You want 20 to 30 percent headroom above your system's peak draw. This keeps the PSU running in its efficiency sweet spot and gives you room to add components or upgrade later. For most gaming builds with a mid-range GPU, 750W is fine. High-end GPUs like the RTX 4080 or 4090 need 850W to 1000W minimum.
Efficiency rating. 80 Plus Gold is the standard for quality PSUs and covers every unit in this roundup except the ROG Loki and THOR models, which are Platinum. Platinum wastes less power as heat, which matters most in compact builds or when running at high loads for extended periods. For most gaming builds, Gold is perfectly adequate.
ATX 3.0 vs ATX 3.1. Both standards handle the transient power spikes that modern GPUs produce. ATX 3.1 is slightly newer and handles larger spikes more effectively. If you are buying now, ATX 3.0 is still fine for current GPUs. ATX 3.1 is worth prioritising if you are planning to keep the PSU for several years.
Modular vs semi-modular vs non-modular. All nine PSUs in this roundup are fully modular, which is the right choice. You only connect the cables you need, which keeps your case tidy and improves airflow. Semi-modular units have a fixed 24-pin and CPU cable, which is a minor inconvenience. Non-modular PSUs are a cable management nightmare and worth avoiding.
Warranty length. Most ASUS PSUs in this roundup carry a 10-year warranty. That is a genuine indicator of build quality confidence. Shorter warranties on budget PSUs from other brands are a red flag worth taking seriously.
Form factor. Standard ATX PSUs fit the vast majority of cases. If you are building in a compact SFX or SFX-L case, the ROG Loki is the only option in this roundup that fits. Check your case specifications before buying.
Price brackets. Under £100 gets you the Prime 750W Gold. £100 to £120 covers the TUF Gaming 750W and 1000W, plus the Prime 850W. Above £150 puts you into ROG Strix territory, and above £200 is the THOR range. The sweet spot for most builders is the £100 to £130 range, where the TUF Gaming units sit.
