Question Is my PSU Size correct?

[gabrielpiccolo4]

I've been experiencing technical issues since building my new PC. Initially, I was getting errors in MemTest86, and games were crashing. However, after reconnecting all PSU cables, MemTest86 now passes, but games still occasionally crash.

Now, I'm wondering if my PSU could be faulty or if its wattage is insufficient. Could you help me figure this out?

My PC Specs:​

• CPU: Ryzen 7 7700
• Motherboard: MSI B650M GAMING PLUS WIFI
• Memory: Kingston Fury Beast Expo 32GB (2x16GB) @ 6000MT/s (currently running at DDR5-4800 CL40-39-39 @1.1V) - KF560C30BBEK2-32
• GPU: RTX 4070 Super 1-Click OC 2X TecLab Lite Galax
• Cooling:
  • Front Fans: 2x Cooler Master Sickleflow 140 ARGB - MFX-B4DN-14NPA-R1
  • Rear Fan: 1x Cooler Master Sickleflow 120 ARGB - MFX-B2DN-18NPA-R1
• Storage:
  • Primary (Windows): Kingston NV2 1TB M.2 NVMe - SNV2S/1000G
  • Secondary: Samsung 850 EVO 250GB
  • Tertiary: Samsung 870 QVO 1TB
• PSU: XPG Core Reactor II 750W

I used several PSU calculators, and they estimate my system's power consumption at around 500W. Do you think my PSU might be faulty, or could it be an issue with power delivery?

I still get errors on MemTest86 if I enable 6000MT/s.

Thanks for your help!

Download OCCT and run the PSU test.

Thanks for the suggestion! I'm going to post the results in about 3 hours. Run for 1 hour is ok you think?

I'm not sure if OCCT is going to catch any issue, I tried using OCCT for memory monitoring while gaming, the games were crashing but it didn't detect any errors.

About 15 minutes should be fine, monitor your CPU and GPU temps also.

Hey, so I ran 30 minutes, it didn't detect any errors. So it means the PSU size is correct?

Max Temperatures:
CPU - 89.00 C
Motherboard - 60.99 C
Memory 1 - 48.50 C
Memory 2 - 44.50 C
GPU - 79.11 C
