Rank #8 in Best PC Power Supply 2026: 10 Ranked, and the Specs That Don't Add Up
ASUS TUF Gaming 850W Gold
Price and rating as shown on Amazon when we collected them. Both change.
The ASUS TUF Gaming 850W Gold is the eighth entry in this guide: a fully modular ATX power supply with an 850 Watt output rating, listed at £96.50 and rated 4.7 out of 5 from 751 ratings. It is the model in this group whose own specification table disagrees with itself most plainly.
The listing gives a Current Rating of 850 Amps and, in the same table, a maximum input voltage of 240 Volts (AC). Multiply those two figures and you get 204,000 Watts from a unit the same table rates at 850 Watts output. The listing also states two fans, each 120 Millimetres, and an item weight of 2.38 kg. Everything below comes from the Amazon listing for this ASUS model — price, rating, specification entries and customer reviews — and not from any testing we have carried out.
How those 751 ratings break down
An average hides its own shape. This is the spread behind the 4.7 stars.

What buyers actually say
Quoted from customer reviews on Amazon
Verified purchase“I recently picked up the ASUS TUF 850W Gold-rated PSU for close to 90 quid and it has exceeded my expectations. This powerhouse delivers rock-solid stability with 80+ Gold efficiency, ensuring clean and reliable power for high-performance builds; even those with demanding GPUs. The fully modular design makes cable management a breeze, keeping the build neat and airflow unobstructed. Plus, the silent yet efficient cooling keeps temperatures in check, even under heavy loads.==PROS:+ 80+ Gold efficiency – Features solid protection against power fluctuations.+ Fully modular – Easy cable management and clean builds+ ATX 3.1 Compatible – Relatively standardised form factor allowing for ATX 3.0 and 3.1 compatibility+ 850W power – Plenty of headroom for upgrades+ High-quality components – Reliable and durable+ Quiet operation – Effective cooling with minimal noiseCONS:- Cables could be slightly more flexible- No RGB (if that matters to you)- 850W of Power does mean CPU, MOBO (in the form of MOSFET), and GPU can run hot. Would need adequate cooling or adjusting fan settings to ensure (e.g., MOS temps) are regulated.- Comes with both the traditional 16-pin PCI-E and the new 12VHPWR (12V-6X2) connector, though the naming could be clearer for newer builders as the new connector is labelled as the 16-pin PCI-E.==Overall, at this price point, it's a no-brainer for futureproofing. 850W provides plenty of headroom for upgrades, making it a smart investment for both current-gen and next-gen hardware. If you want a dependable, well-built PSU that won't let you down, this one is an easy recommendation, especially for something as vital for your PC as the PSU.~Shaker”
Verified purchase“After your GPU and CPU I'd argue the PSU is a key component in your gaming or creator setup. I bought the TUF gaming PSU so it aligned with the rest of my setup and I'm certain the extra oomph from 650w to the 850w is a good reason why my renders and gaming haven't gotten bogged down recently. Don't buy just enough. Over provision and you'll see an improvement, NOT A Guarantee but it might help.”
