Upgrading PSU

I have been having games lag and pc turn off. It's the 750x PSU.

 

I am going to upgrade but want to know, should I buy the 850 or 1000.

 

I am planning to buy the rm1000x shift. It has ATX 3.0 and it's good. Great result and review.

 

Should I buy the 850 or 1000. There's an offer on right now 20%off.

 

Thanks.

How old is the psu? It's not necessarily the psu. Try doing all your windows, bios and driver updates first. But the rm1000x shift would be the best out of the two

Yeah I rather have my doubts on the PSU being a problem unless its quite old, but then if it was still in warranty you could RMA it and see if they find a problem.

 

I've ran an RTX 3080 on an RM650x without issues and the 4080 doesn't have the high transient problem of the 3080.  I also run a 4090 on an RM850x with a 5950X.

Yea idk what it was. I have all my things updated. I spent hours looking into everything to see if they were the latest version. I play PUBG and my pc restarts when i play that game. Everyday at least once. Quite Annoying to be fair.

Only with PUBG? Check your cpu usage as well as temps in game. How old is the PSU?

I built my PC in 2019. I have the Corsair RM750X. So I'm thinking it is 2019 version or the 2018.

Its either the 2018 or 2019 version of RM750x. The CPU load and the GPU load is fine. That's the thing. I tired looking up for some solutions, nothing.

 

I once thought it was my RAM or RAM slots but I don't crash when just surfing the net and stuff.

try reseating the ram, cpu and gpu. Also the power connectors on the motherboard

You could also grab the official Premium 12VHWPR cable, its better than the cable that comes supplied with their ATX 3.0 version of their PSUs.  I don't like the weight of the adapters of the socket, or how stiff their standard cable is.

They don't actually HAVE real ATX 3.0 PSUs (which is not a problem as it only adds the ability to automatically limit power output if you have two 600W cables plugged into a PSU that is less than 1200W), they just bundled in the standard cable their older models use.

Ahhhh. I only recently found out about the ATX 3.0 yesterday through the PSU tier list website and thought the concept was amazing.

 

Ohh and people multiply their wattage usage in the PCPartPicker by like 1.5 or something? Is this something that's legit?

The reason for going higher is to have a safety margin as pushing a PSU to 100% is likely to wear it out faster due to it being less efficient and creating more heat.  So generally you aim for somewhere between 60-80% load.  Also as a PSU ages its likely to find it harder to maintain a stable output at a high load, if you keep it somewhere in the middle its a win win as its likely you will get a lot more years out of it.

 

In the real world, I haven't seen my 7800X3D + 4090 + 55" OLED TV combined really go over 650W from the wall, and PSU ratings are their output, what they pull from the wall to achieve that would be higher.

As I said earlier, I've pushed my luck many times, usually with no issues.  The 3080 however was fine on an RM650x but the PC would randomly shut down on a Cooler Master Mastercool 650W.

Amazing! thanks man!
