GAMDIAS ASTRAPE P1-750G RGB Power Supply review


CPU: Intel Core i7-8700k

Motherboard: ASUS ROG Maximus X Apex

RAM: 32GB Corsair Dominator Platinum 3200Mhz

GPU: ASUS ROG GTX 1080Ti Poseidon Platinum

SSD: Samsung 960 PRO 2TB

OS: Windows 10 Professional X64


We’ll start out saying we aren’t equipped to do extremely detailed electrical analysis required to pick apart a modern power supply. It takes laboratory grade dedicated equipment so we’ll have to make do with some less precise testing.

While we normally use a good Fluke Digital Multi-meter, we’ve found the onboard monitoring solutions in modern motherboards to be quite accurate and able to be easily logged with utilities like HWiNFO.

Gamdias promises +/- 3% regulation and based on a run of Futuremark 3DMark Timespy system stability test, we got the above as measured by HWiNFO. You can see the +12V rail runs a little hot but still is well within not only ATX specs, but Gamdias’s more stringent guidelines.

Next, we’ll look at ripple in the rails with our Owon VDS-1022/I Digital USB Oscilloscope.

 The +12V rail under a stress test load registers a peak of 16mV peak to peak. While not the best on the market, this is a fairly decent result.

 The 5-volt rails fairs slightly better at around 12mV of ripple.

The 3.3V rail does great with only 4mV of ripple. This is really pushing the limits of what our lower cost O-scope can even pick up.
