Rated at 850 W and certified with an 80 PLUS Gold efficiency rating, the GamerStorm 80 Plus Bronze Vertified SMPS delivers serious capability for demanding systems while maintaining energy-wise operation.
At its core, the GamerStorm PSU PN850D Desktop SMPS supports the ATX12V V3.1 standard, making it well suited for modern builds with high-draw graphics cards and next-generation CPUs.
Its design includes new safety margins for power excursions and provides stable current even when components demand large instantaneous loads.
Coupled with its high-efficiency certification and a gold rating from Cybenetics, the GamerStorm 850W Black Desktop SMPS ensures that you’re not only getting the power you need but doing so with smart energy usage.
The internal architecture is equally robust: an active power factor correction stage, a full-bridge SRC LLC design and DC-to-DC conversion for minor rails enable strong regulation and clean output.
The hold-up time of ≥16 ms at 80% load ensures that short power dips won’t immediately cripple your system.
Add to that a high-quality 120 mm fan — with either hydro or rifle bearing depending on the variant — and you’ve got a unit that manages both cooling and noise effectively.
One of the standout features is the dedicated 12 V-2×6 (16-pin) cable capable of delivering up to ~600 W for modern GPUs.
This is especially helpful in high-end builds where the graphics card alone may require very high 12 V rail support.
The fixed cable design means all connectors are built in from the factory — while this means no modular flexibility, it also means fewer points of potential failure and a simpler installation for many users.
Durability and protection are baked in: the GamerStorm Powerful 850W Desktop SMPS includes OPP (Over Power), OVP (Over Voltage), SCP (Short Circuit), OTP (Over Temp), OCP (Over Current), UVP (Under Voltage), NLO (No Load Operation) and SIP (Surge/Inrush Protection).
That’s a full suite of safeguards guarding your investment.
And the confidence the manufacturer places in the build is clear with a 10-year limited warranty — a strong commitment for a PSU in this class.
The operating envelope accommodates 0-40 °C typical environments and supports high altitude use (up to ~5,000 m), giving even more flexibility for unusual or custom installations.
The compact 150 × 140 × 86 mm form-factor ensures compatibility with most standard ATX cases.
The GamerStorm PSU PN850D Desktop SMPS brings together serious power-delivery, modern compatibility, strong efficiency and robust protection.
Whether you’re building a high-end gaming rig, a creator workstation or prepping for future-proof upgrades, this PSU provides a solid foundation.
Its fixed-cable design may not suit every modular-preferring user, but if you’re after reliability, value and performance — the GamerStorm PSU PN850D Desktop SMPS delivers.
