Frequently Asked Questions

Technical FAQs & Store Policies

What are the real-world advantages of 80 PLUS Platinum over Gold?
Platinum certification requires 92% or higher electrical efficiency at 50% load (versus 90% for Gold). This delivers lower heat output, reduced power draw from the wall, and near-silent operation because the fan barely needs to spin up.
Why are 100% Japanese capacitors important?
Japanese capacitors use advanced electrolytic formulations rated up to 105°C, ensuring exceptionally low internal resistance (ESR), razor-sharp voltage ripple control, and years of unwavering reliability.
Can this power supply drive high-end graphics cards?
Yes. With 6x PCIe 6+2 pin connectors and a massive 70.8A single +12V rail, it effortlessly powers high-end gaming GPUs like the RTX 4070 Ti SUPER, RTX 4080, and Radeon RX 7900 XT.
How quiet is the 135mm FDB fan?
Because it is 135mm (larger than standard 120mm fans), it moves greater airflow at lower RPMs, maintaining virtually silent acoustics under general gaming sessions.
Is the unit fully modular?
Yes, every single cable is completely detachable, allowing you to route only what your system demands for an immaculate build.
Is this power supply 100% genuine and backed by official warranty at AHW Store?
Yes! Every power supply sold at AHW Store is 100% authentic, factory-sealed, and backed by authorized local distributor warranty in Egypt with direct technical support and replacement. Details in our Warranty Policy ↗.
What payment and installment plans are available in Egypt?
We offer cash on delivery across Egypt, credit cards, and flexible 0% interest installment plans through ValU, Sympl, Forsa, and bank credit cards. See our Payment & Installments Guide ↗.
How fast is shipping and delivery across Egypt?
Orders are delivered within 2 to 7 business days across all Egyptian governorates in reinforced protective armored packaging (with pickup available from our 6th of October headquarters). See Shipping Policy ↗.
Can AHW Store install and stress-test this PSU in my complete custom PC build?
Yes! Our certified hardware engineers can assemble, wire with precision cable combs, stress-test under maximum electrical load, and calibrate custom thermal profiles. Explore our Custom PC Builder ↗.
What is the return and replacement policy at AHW Store?
