[SOLVED] Power Loss ruining my life!

[Matinho]

Hi all, this is my first post so apologies if I’m the wrong place. I’ve built my first computer over the last 6 months but have recently ran into problems so was hoping some of you would be kind enough to offer some advice. After 20-30 minutes of low/medium demand gaming (Starcraft, grim dawn), my system completely shuts off as if I’ve pulled the plug. I switch it back on, start up again and invariably it will happen again every 10-20 mins, sometimes when performing tasks in windows. So far I’ve tried:
Swapping out both RAM sticks
Replacing the PSU under warranty
Unplugging/rewiring the whole system
Updating bios for MB, GPU
Switching off fast restart
Updating windows
Running diagnostics with both defender and AVG
Running RAM test
Checking loads and temps on CAM software (all normal/low)

Today when the same thing happened it took several attempts to get it to switch back on so I’m getting concerned the problem could be about to get worse. Could anyone offer any advice on what could be causing it or possible further fixes?

Parts Used;
Intel Core i5 7500 3.4Ghz Inc Cooler
Motherboard MSI B250I Gaming Pro AC
PSU EVGA 450 BR 450W 80+ Bronze
RAM Corsair Vengeance LPX 8 GB (2 x 8 GB) DDR4 2400 MHz
GPU Asus Strix Radeon RX570 4GGB
SSD 240GB Kingston A400 Solid State Drive / SSD
2 x 80mm fans plus 1 x 200mm Case fan


Thanks in advance for any help

Forgot to say, I’m running Windows 10. I’ve also totted up my parts and think 450w should be more than fine for a PSU

Take a moment to go here:

Plug in all your parts and see what recommend it gives for a PSU.

My initial thoughts are that you are loaded the PSU to a degree that sustained use it causing it to shut down on a thermal.

Thanks very much for replying. I inputted parts and came out with the following;
Load Wattage 282W
Recommended UPS rating 700va
Recommended PSU wattage 332W

Based on that I would have thought 450W would be ok but it recommends an EVGA 600W B1 80+

I wouldn't be too concerned about it's "recommend", think of it more as an ad.
Do consider looking at some reviews and specs of your current PSU and see what it's continuous wattage and peak wattage are in relation to that ballpark load.

Replace the PSU with a good quality unit, the one you have is a budget model.
