Quick Answer
Disconnect power supply completely from PC components. Insert bent paperclip into 24-pin ATX connector, bridging green PS_ON wire to black ground wire. Plug unit into wall and switch on. Spinning fan confirms power delivery, not correct output voltages. Do not touch metal jumper while power supply is energized.

Overview: The PNY NVIDIA GeForce RTX 5080 Epic-X ARGB OC is a high-end triple-fan graphics card based on NVIDIA Blackwell architecture. Its 2.99-slot cooler and ARGB styling give it an enthusiast-focused design that should appeal to builders who want both performance and a premium look.
Performance: With 16GB of GDDR7 memory, a 2775 MHz boost clock, PCIe 5.0 support, and HDMI 2.1 plus DisplayPort 2.1 outputs, this card is aimed at demanding gaming and creator workloads. NVIDIA DLSS 4, Reflex 2, and RTX AI features add meaningful value for smoother gameplay, lower latency, and AI-accelerated tasks.
Drawbacks: The large triple-fan, 2.99-slot format may not be ideal for compact cases, and the card sits firmly in the premium segment rather than the value segment. The manufacturer listing also does not provide full dimensions or power details, so buyers should verify case and system compatibility before purchase.
Verdict: This model is best suited to enthusiasts who want a powerful RTX 50 Series GPU for modern gaming, content creation, and AI-enhanced workflows. If you have the space and want current-generation NVIDIA features, it is a strong high-end option.
Pros
- 16GB GDDR7 memory offers a modern high-speed VRAM configuration.
- DLSS 4 and Blackwell architecture provide current-generation NVIDIA feature support.
- PCIe 5.0 compatibility prepares it for newer desktop motherboards.
- SFF-ready positioning adds flexibility for smaller PC cases.
Cons
- The listing does not provide dimensions, so case fit still needs to be verified before purchase.
- Power requirements are not listed in the manufacturer listing, which makes system planning less clear.
- Its high-end feature set may be more than casual users need for basic gaming or everyday use.
Overview: The GIGABYTE GeForce RTX 5080 AERO OC SFF 16G is a desktop graphics card built on NVIDIA Blackwell. It pairs the AERO OC design with WINDFORCE cooling and an SFF-ready focus, which makes it notable for buyers who want high-end GPU performance in a compact-friendly format.
Performance and Features: Key specifications include 16GB of GDDR7 memory, a 256-bit memory interface, PCIe 5.0 support, and DLSS 4. These are strong indicators of a modern enthusiast-class GPU suited to demanding gaming, streaming, and GPU-accelerated workloads where bandwidth and current NVIDIA features matter.
Drawbacks and Considerations: The manufacturer listing does not include dimensions, power draw, or included accessories, so buyers should confirm compatibility with their case and power supply before ordering. As a top-tier RTX 5080 model, it is also likely to be more capable than many everyday users require.
Verdict: This card makes the most sense for enthusiasts and builders who want a current-generation NVIDIA graphics solution with premium specs and SFF-aware design. If you are assembling a high-performance desktop and want strong feature depth without giving up compact-build flexibility, it is a compelling option.
What the Paperclip Test Shows
The paperclip test, or jump test, is a binary power-up check for ATX-class power supply units (PSUs). A motherboard normally commands the PSU to start by pulling the PS_ON# signal (green wire, pin 16 on the 24-pin connector) to ground (COM). The signal is held near +5 V by an internal pull-up. When it is pulled below 0.8 V, the PSU enables its main converters. Bridging PS_ON# to a COM pin with a conductor reproduces this command without a motherboard.
A successful jump start confirms only a narrow set of conditions:
- The AC input stage, including the fuse, bridge rectifier, and standby supply, is functional.
- The +5VSB standby rail (purple wire, pin 9) is present, because the PS_ON# logic is powered from it.
- The primary-side controller and at least one main converter can start under minimal load.
- The fan controller is receiving power, subject to the fan-curve caveats covered below.
The test does not verify regulation under load, ripple and noise, transient response, hold-up time, or protection circuit behavior (OVP, UVP, OCP, OPP, SCP, OTP). A PSU that starts unloaded can still fail under real current demand. The jump test is therefore a go/no-go screen for gross failure, not a validation of health.
Safety Before You Start
The paperclip test is low-risk when the PSU enclosure stays closed and only the low-voltage output connector is handled. The hazards are concentrated on the mains side and in the DC output current capacity. Manufacturer documentation specifies nominal inputs of 100-240 VAC at 47-63 Hz. Inside the case, the active PFC bulk capacitors charge to roughly 380-400 VDC and can retain a hazardous charge after unplugging.
