Thermal Grizzly WireView GPU - 2x8Pin PCIe Reversed - GPU Power Consumption Measuring Device - PCIe Power Connector - Real Time Direct Monitoring - Made in Germany

Before I picked this up, I reached out to Thermal Grizzly, and they were super helpful. The RTX 5090 is still relatively new, and since I’m running the ASUS ROG Astral GeForce RTX 5090 32GB GDDR7 OC Edition, I wanted to be absolutely certain I was ordering the correct version.Correct version, you ask? That’s where things get tricky.Over the past few GPU generations, we’ve seen multiple shifts in power delivery design—especially with high-wattage cards like the 30-, 40-, and now 50-series. Add to that the evolution from legacy ATX PSUs with multiple PCIe cables to modern ATX 3.1 units with native 1x12VHPWR connectors, and it becomes easy to misorder the wrong adapter or cable.You may remember the cable-melting headlines from the 30- and 40-series era. Some of those issues stemmed from poor cable design, others from user-side cable strain or incorrect seating. In response, NVIDIA and PSU makers quietly introduced tweaks to connector pinouts, latch placement, and sense pin behavior—meaning today we have a small but confusing variety of power cable types and alignments.Thankfully, the Thermal Grizzly team sent over a full technical diagram and confirmed which model I needed. I ended up going with the WireView 1x12VHPWR Reversed, which fits my card and case layout perfectly.Now—let’s be honest—the clean 180-degree “U” bend the WireView introduces is fantastic, especially if you’re working with a tight case layout or want to eliminate stress on the cable. But that’s really just a bonus. The real reason to buy this product is the integrated power usage display, and it absolutely delivers.The built-in screen is crisp and easy to read, and offers several useful modes depending on what kind of data you want to monitor. There’s a basic "Display Power" mode that shows current power draw in watts. "Display Details" expands this to include real-time voltage and current in volts and amps. "Display Stats" gives you the minimum and maximum wattage values observed, and "Display Energy" shows your average consumption (AVG W) along with total cumulative energy use (E). In my case, I just leave it in standard wattage mode, where it consistently shows usage just under the rated 600W during heavy testing—exactly what I’d expect from a high-end card like the Astral 5090. When I’m not running stress tests or benchmarking, it idles comfortably around 25 to 30 watts. It's a simple but powerful tool for confirming that your GPU is drawing what it should, and nothing more.Even though I have plenty of clearance inside my chassis, the safe bend this adapter introduces still gives me peace of mind. And if you’re building in tighter spaces, it could be the difference between a clean install and a messy or even dangerous one. Just make sure you double-check compatibility before ordering. WireView comes in several flavors depending on your PSU (native vs. adapter cables), GPU orientation, and connector style.In my case, I have a native ATX 3.1 PSU with built-in 12VHPWR cables that include security features like yellow tip indicators to confirm full seating. The "Reversed" in this context means the latch is on the top and the sense pins are on the bottom, which aligns perfectly with how my 5090 is oriented. But not all cards are the same—some will need the standard (non-reversed) layout. If your GPU is a generation or two behind, or if you're using adapter cables instead of native ones, be sure to cross-reference everything carefully.Now onto build quality: this thing feels premium. The WireView came in a resealable foil pouch, and inside that was a small presentation box that honestly gave me "high-end ring box" vibes. Inside, the connector was securely cushioned and looked and felt more substantial than I expected. There’s a clear emphasis on durability and precision engineering here—this is not a budget-tier throwaway adapter.One concern I had going in was compatibility with my card’s power detection circuit. The WireView uses what looks like just two wide contact blades to interface with the GPU. It’s a clever design, but I was wary it might confuse the Astral’s power sensing logic. I’m happy to report it worked flawlessly: the sense pins engaged, and GPU Tweak III confirmed everything was good with a big green check mark next to 12VHPWR status.To put it to the test, I ran a FurMark 2 stress benchmark to simulate sustained GPU load, and monitored the connector using a FLIR thermal camera. After a prolonged high-wattage run, the WireView reached a peak of just 31.2°C (about 88°F). With an ambient room temperature of 72°F, that’s a modest and completely safe delta—solid evidence that the connector handles thermal load efficiently and without issue. There were no signs of thermal stress or localized hot spots, and the FLIR image confirms stable heat distribution across the connector housing.Bottom line? This is a solid, thoughtfully designed adapter that solves a very real problem cleanly and elegantly. If you’re building with a modern GPU and want real-time power monitoring plus cleaner cable routing, this is absolutely worth it. Just make sure you order the right version for your specific setup—once you do, it’s smooth sailing.One very important note: all modern GPU power connectors—regardless of brand or adapter—are susceptible to improper seating. It is absolutely critical that you install both ends of this adapter correctly: the adapter to the GPU, and the adapter to your PSU cable (or directly to the PSU if you're using a native ATX 3.1 cable). Improper seating is one of the most common causes of failure, and can result in anything from flaky behavior to a literal cable melt-down. Double-check your work. Make sure there are no visible gaps between the connectors. Use a flashlight if needed. This isn’t just for WireView—it applies to all modern 12VHPWR GPU-to-PSU cabling, and it matters.

Excellent for what it is advertised to do and I trust Thermal Grizzly's Quality control with their products. Works well with my 9070XT red devil and shows all the proper fluctuations and wattage in real time.

The wire view by Thermal Grizzly is a must have tool for the PC Enthusiast. Even the average joe could use it to see power consumption and voltage drop on GPU.But when it comes to the Strix 4090 and Overclocking I would not do it without this tool.Now I need for one for my PNY 4080. Not needed for this GPU but it looks cool and can help with tuning/undervolt.

First off, this seats very well, with no wobble whatever. The power readings seem to match the software readout. I have run the OCCT power stress test; the card (RTX 4090 SUPRIM LIQUID X) draws over 520W for 5 minutes. I don't have an infrared camera but the connector never felt warm. I doubt this meter will cause future problems. I have run various 3DMark tests; the performance of the card is not affected. It's a bit pricey but not for what it does though it definitely is in the nice-to-have category. But I do like being able to see the power on occasion. This and the Asus BIOS Q-Code display are pretty much all the LED's I have on the system.

In 3d mark I began seeing odd frequency spikes and some occasional instability in general after installing this on my 4090. Prior to that everything ran perfectly. Once I removed it things returned to normal. It seems like good idea but the downsides were pretty serious for my rig.

This works great to be able to monitor how much power your gpu is using. Make sure you are buying the correct version for your gpu.

I ordered this product assuming all three plug PCI cards are the same spec but they're not apparently msis plugs are slightly farther apart so this will not work. Luckily Amazon dead refund my money and accept the return. Just a PSA it is a great piece of Hardware wish I could use it

Helped with my cable management and looks cool at same time.
