Testing / condition

• Powered on. Fans turn on.
• This is NOT a full load-bench, ripple, or ATX-spec validation. I did not run it under sustained high load or measure voltages with a dummy load / oscilloscope.
• Used in crypto mining = long hours at high load. Expect cosmetic wear, dust history, and unknown remaining capacitor / fan life.
• Labels and warranty sticker are present as shown. Do not assume manufacturer warranty is valid or transferable.

BUYER BEWARE — READ BEFORE offerDING

• SOLD AS-IS, WHERE-IS, WITH ALL FAULTS.
• No manufacturer warranty is offered or implied. Original EVGA 10-year coverage was for the original purchaser from an authorized reseller and is almost certainly expired or not available to a subsequent owner.
• Mining use shortens expected remaining life versus a lightly used desktop PSU. Capacitors, fan, and connectors can fail after years of 24/7 load even if the unit powers on today.
• A PSU that “fans spin” can still have bad capacitors, high ripple, weak rails, or fail under load and take out a motherboard, GPU, or drives. Use at your own risk.
• Inspect on arrival. Test with a known-good system or PSU tester before connecting expensive hardware.
• Photos are similar to the actual unit. What you see is what you get.
• No returns for “I didn’t realize it was used for mining,” “I wanted a quieter fan,” “it doesn’t pass my load test,” or “warranty won’t register.” Mining use and limited testing are disclosed up front.
• Shipping: packed as a used electronics item. I am not responsible for carrier damage after a signed/delivered scan, or for issues caused by incorrect installation, adapters, or overloaded connectors.

Questions before you buy are welcome. If you need extra photos of specific cables or the fan grille, ask.
