Fancy PSU, overpriced but the looks make it worth it
Tiny little beast! I 100% bought this based on looks, judge me I don't mind! While building on Lian Li A3 white, Asus ROG B850-G and AERO 5080 SFF this PSU was just what I needed to complete the look and provide power to my PC. It's overpriced like all Asus ROG line product are, you know that but you still buy it because they look good. Cables are AMAZING, you won't need to buy any mods as the included ones are easy to work with, very soft. Overall love how it looks and quality seems to be good, only time will tell, nice touch to have RGB on the fan and nice that can be controlled by the MB

Solid
Quality built as expected from asus Tons of cable options provided and they are braided and of good quality Grade A on Noise rating - really quiet and silent even on idle Nice white colour Got this at a discount Be warned that this is SFX-L so needs some cable management to fit into smaller cases

Asus ROG Loki 850w Platinum ROG White SFX-L form factor in a Lian-Li Dan White A3 case.
I never thought I’d want to display a PSU in my builds, but with the ARGB and stunning case design, I had to make it stand out in my case. I was a little worried about the extra 30cm being an SFX-L but it was fine. One point of concern you may also have ,is only seeing only 3 PCIE/CPU sockets on the PSU, luckily theres another supplied 12VHPWR-2XPCIE cable breaks out into 2 more GPU only PCIE socket to power other brands like AMD/Intel GPUs. The main 12VHPWR-12VHPWR supplied white sleeved cable was of a high quality which I used on my RTX 4090. I don’t think this 850W PSU will be able to power a 5090 very well, and with the cable issues I’d aim for an ATX 3.1 and be doubly sure the cable works with no issues. With the current discounted price of £149 + other ASUS offers this great PSU was a no brainer for me. If I do get a rtx 5090 I’ll be getting a 1200W+ PSU. If only ASUS made a 1200w white version…..

Great quality product.
Great product. PSU very quiet as advertised. very nice product, nice lights, addressable RGB. Solid build, cables also soft and doesn't feel cheap plastic like other products. Great design. Perfect for my Q58 build.

Quality can’t be beat
Very well built and works perfectly. No noise level. Powered everything up immediately. Quality is amazing. The box has everything you could possibly need with easy installation.

EFFICIENCY!!!
I decided to spend a little more money on a platinum rated psu, as I assume it’ll save electricity fees in the long run. Based on its appearance it seems high quality (I expect no less from ROG products) Currently I’m waiting for the rest of my parts to arrive so I can fully test this over the span of a few months. Hopefully I remember to update this review with how this psu performs and any recommendations I have. I love the braided look of the cables, and the fact that they are thin, will make the fitting a lot easier. They also include cable ties for organisation. To top this off they have a 10 yr warranty

Absolute let down - Would not power on
Arrived dead and faulty, I doubt it’s a manufacturer fault but returning is such a ball-ache and a long process. Amazon delivery need to be more careful & PLEASE opt for more packaging if you do buy a PSU.

Absolutely amazing sfx-l power supply and silent as well!
Amazing power supply. Silent even under heavy load and looks stunning with the rgb lighting on the fan. I'm using a 9800x3d and 5080 and it powers these with absolutely no issues whatsoever. Highly recommend the Loki 850w psu for anyone looking for a quiet reliable psu.

Ich habe das ASUS ROG Loki SFX-L 850W Platinum gekauft. Es ist ein richtig gutes Netzteil für Gaming-PCs. Es ist klein und passt super in kompakte Gehäuse, bringt aber trotzdem ordentlich Power. Die Kabel sind hochwertig, lassen sich gut verlegen und sehen sauber aus. Besonders cool ist das Lüftungsgitter aus Metall – sieht edel aus. Der eingebaute RGB-Lüfter bringt Farbe ins Gehäuse und läuft dabei richtig leise, selbst wenn der PC mal mehr zu tun hat. Insgesamt ist das Netzteil top verarbeitet, leise und ideal für alle, die ein starkes, schickes und platzsparendes Setup wollen.

PSU bought for a later upgrade of a ZEN4 CPU to ZEN5. Challenge to fit into a SFF case but quality of cabling allows for proper cable management.

Alimentatore PC in standard SFX-L. Marca ASUS, modello ROG LOKI 850M Platinum, versione color bianco, prodotto in Cina. Pro: + Qualità materiali, costruttiva e delle finiture +++; + Tanta potenza disponibile (850 Watt); + Modulare con cavetteria molto bella; + Illuminazione integrata ARGB (Aura Sync); + Estremamente silenzioso (25dB e ventola spenta sotto il 40% di carico); + Alta efficienza con capacitori giapponesi (80 Plus Platinum); + Garanzia 10 anni; + Logo CE presente. Contro: - Cavi bianchi ma potevano fare bianchi anche i connettori e non grigi come sono. Non avevo bisogno di un nuovo Ali, ma avendo cambiato PC con Case e MoBo bianchi ho voluto "spallare" e fare un "total white" compreso alimentatore e cavetteria. La qualità dell'alimentazione è basilare per ogni tipo di elettronica e mai lesinare su questa componente, pertanto ho voluto avere il massimo disponibile sul mercato e ASUS è una garanzia. Il mio Case è un Jonsbo TK-0 (Amazon ASIN B0DX2KDFWW) e un Ali SFX è perfetto ma ci entra bene anche questo SFX-L, l'unica nota è che i cavi di questo ASUS sono abbastanza lunghi per un SFX e bisogna lavorare di fascette per sistemarli bene dentro. In dotazione abbiamo sia fascette classiche in plastica bianca che fascette in velcro sempre bianche.. peccato che hanno fatto i connettori dei fili grigi e non bianchi (nelle foto pubblicate sembrano in tinta), vai a capire perché. Installato da pochi giorni ed è perfetto, il mio sistema non è molto energivoro e per quanto mi sembra credo che la ventola o non si sia mai accesa o sia del tutto inudibile. Non ho testato l'illuminazione integrata, visto che il mio Case che ha un secondo vano chiuso dedicato all'Ali. 850 Watt sono tanti, al momento non mi servono ma chissà in futuro, quindi è un investimento che ammortizzerò con il tempo e, visto il costo, i 10 anni di garanzia del produttore sono il TOP. Io sono super soddisfatto e posso solo consigliare questo ASUS ROG Loki.

⭐️⭐️⭐️⭐️⭐️ Potencia compacta y silenciosa para mi PC pequeña Como fan de los builds SFF, estaba buscando una fuente potente pero compacta. Esta ASUS ROG Loki 850 W SFX‑L Platinum ha sido un acierto total. La instalación fue simple, los cables son flexibles y de calidad, lo que facilitó el cableado en mi caja pequeña. Lo más sorprendente es lo silenciosa que es: en reposo ni se oye (modo 0 dB bajo el 40 % de carga) y bajo carga intensa sigue siendo susurrante, incluso durante partidas largas . Además, su eficiencia Platinum y la certificación Cybenetics Lambda A respaldan su rendimiento “verde” y fiable . Estéticamente, es una joya: aluminio pulido, logos ROG iluminados ARGB que sincronizan con el resto del equipo . Y viene con 10 años de garantía, cosa que me da mucha seguridad . En mi experiencia real, con un 7800X3D y una RTX 4080, la fuente nunca ha fallado ni escatimado potencia, y el ventilador solo se activa muy esporádicamente, sin molestar . --- Pros: Formato SFX‑L muy compacto con cables flexibles Extremadamente silenciosa y eficiente (certificación Lambda A) Estética ARGB premium y garantía de 10 años Contras: Precio elevado comparado con opciones sin RGB No es compatible con cajas que solo admitan formato SFX (no–L) --- En resumen, si montas un equipo potente en formato compacto y quieres estética y tranquilidad, esta Loki es top.

No doubt this is one of the best white psu for white themed ITX builds for ITX casing. The power supply is totally fine and works perfectly
