I think my Corsair CX 750 on its way out, I think it might not be supplying enough power. Today noticeable went to play Star wars Battlefront 2 and pc rebooted, checked event viewer, critical at 16:44 unexpected loss of power. It may have been glitchy mid last year. Corsair RM850X priced at £118 could possibly primenow one tonight. Is it recommended or overkill? AMD Ryzen 1600 GTX970 strix Mostly Green HDD x 3 I think one is 7200RPM Black. 1 x SSD Seems to be working fine at the moment
850w is major overkill. I think 550-650w for a single card system like yours would be about right. That is, if it is the PSU that's at fault, otherwise you could be throwing money away.
You could check a PSU calculator - lots of manufacturers have them (be quiet, coolermaster definately have). I would link but i'm on my phone. But yeah it's overkill my 650w is overkill for my 3770/16gb/4xSSDs and 1080.
The graphics card and the PSU are the oldest components in the system 3-4 years old, I do want to go back to a modular PSU, my case isn't that wide and the older 4 way molex wires are tied up at the bottom of the case. So would like to clear that space up at the bottom of the case. The rest are in the back compartment power and sata cables.
Thanks, will be changing the Ryzen system to a more solider/efficient supply and go from there, A clean install was not done straight away until 3 months after changing from intel to AMD.
Worth noting for anyone looking at this thread in the future, There are two ways to buy a PSU, to meet your wattage or for maximum efficiency and lifespan. Meeting your wattage is obviously cheaper, check the coolermaster wattage calculator, and go 100w above your max load for head room and future proofing. I personally go for maximum efficiency and extending lifespan. A PSU ideally likes to sit on load at about 60% usage, this is where the gold,platinum ect ratings come from. So if your system is pulling 450 at load from the wall, a 800-850w PSU is best for lifespan and efficiency. Not necessarily overkill depending what you want but people that always buy 1000+ watts are almost always over kill and not actually running there PSU efficiency, as under loading can be as bad as overloading in efficiency (not stress)
For a titanium rating psus have to hit 90%+ efficiency on 20%, 50% and 100% loads. Actually, looking at it the Titaniums (must resist urge to abbreviate! ) they need to hit that om 10% loads too - didn't know that. Any 80plus rated psu tends to differ by about 3% or 4% on the different loads with a minimum of 80% efficiency across 20/50/100. They're pretty good nowadays. Whatever the case investing well in a psu is the best policy. My Be Quiet cost a bit at the time but 8 years on and it's still going strong. Probably helps that the components it powers have got more efficient over the years.
Installed and good, the unnecessary wire mass at the bottom of case is no more. I wasn't bothered about them on a bigger case, they could be hidden easier. I just needed to move the optical drive down a bay.
