Looking for a new PSU

[DelphinusVyse]

My computer has definitely been around the block so I can't say I'm terribly surprised that it's starting to intermittently freeze on me. Sometimes it comes back to normal, sometimes I have to turn it off and back on. My money is on my PSU starting to fail since I bought it way back in 2009 and it'll be 10 years old in October (Corsair HX750). I can't afford to replace the whole system right now, so I'm looking at these two PSUs.

Corsair RMx 750W https://pcpartpicker.com/product/79tQzy/corsair-rmx-2018-750w-80-gold-certified-fully-modular-atx-power-supply-cp-9020179-na 

EVGA GQ 850W https://pcpartpicker.com/product/2BcMnQ/evga-power-supply-210gq0850

 

I lean toward the Corsair because the one I have has clearly been a champ, it has double the warranty length of the EVGA unit, is a bit smaller than both the EVGA PSU and my current one so I will have more room to work the wires around my bottom-mounted case fan, and I can buy it at work rather than waiting for shipping. On the other hand, the EVGA PSU is almost $25 less than I can get the Corsair PSU for after factoring sales tax, shipping, and rebates between the two. It's also an 850W, which I don't 'need' but having a little extra breathing room for when I do finally get around to doing a full rebuild can't hurt. Does anyone have any thoughts between the two? Perhaps any suggestions of other PSUs I should consider?

RM750x is a solid choice.

Freezes in the OS aren't going to be caused by your power supply. It's more likely your storage drives which are failing. Following that CPU overheating, virus, etc.

Fair enough. I should also add that previous to my original post I did have my CPU overclocked, so the first thing I tried was resetting it back to stock settings. This seems to have made the freezing happen less often, but it still happened again today for the first time in 2 days. I also forgot to mention in my original post that I get some occasional audio glitches sometimes, particularly when watching youtube, but sometimes in a game also, where the audio seems to stutter on the same sound for a brief moment, maybe a third of a second or so. Anyway, I've run a long test with Seatools on all my hard drives, they all passed. Before with the overclock my CPU would generally run in the high 60s or low 70s while gaming, and now being reset to stock, it's only getting up to about 57C, so I don't think overheating is an issue either, really shouldn't be as I have a more than adequate heatsink and my computer is clean of dust and such. I also ran some malware scans as well which came back clean.

 

Tomorrow I'm going to try swapping out some things to see if I can narrow this down further. I recently had my RAM replaced under RMA due to discovering one DIMM was faulty, and the replacements passed memtest86 just fine, so it's not my RAM either.

 

Update: The spare motherboard I borrowed to swap out turned out to be bad and wouldn't even post, so that wasn't much help. Since options for replacement socket 1155 boards are pretty limited at this point beyond buying used where returning it is likely to not be an option, I decided to go ahead and try the new PSU first. (I'd love to just get a new motherboard and the CPU and DDR4 RAM to go with it but can't afford it right now.) Anyway, have my original build back together now with the RM750x I picked up at Best Buy knowing I can return it if it made no difference. Too early to say if the freezing is resolved of course, but the skips/pops in audio from youtube seems to be gone. Before it would actually be worse if I left a video playing in one tab and started browsing and particularly scrolling in another tab, now it plays clear with no issues. I'll come back and update with what happens after a few days. I figure if I can go a week or so without any freezes, I'll consider this resolved.
