My Asrock RX7900GRE Steel Legend OC will draw over 450w if I enable max power, even undervolted it pulls around 300w depending on the game.Maybe I was a bit to over confident with the PSU and should have upgraded earlier.
I was intending to pick up a Lian Li SP 850 in August but I might have to bring this forward.
I kept the 650 and went through all the PSU calculator website, Reddit, OcUK forum and based my choice to keep it as they said different values and requirements. I didn't however double check the 12v rail amps on the actual PSU. Lesson learned, check the manufacturers site only next time lol.
I do have a Corsair RM750e 2023 I think, will check it tonight and if it have the amps then I may move it over as a stop gap for now until I can pick up the Lian Li.
Yeh thats what my issue was.Its the power spikes that the psu can handle during heavy gaming is generally what to watch for. Not just the max wattage rating.
How old was your PSU?Yeh thats what my issue was.
Was using a Corsair 850W PSU Platinum.
But it was old and that's what was happening...
Power draw on some of the AIB cards are insane my Sapphire Pulse 7900gre is around 250-260w @stock and never goes above 300w even with the powerset to the max in the driver lolMy Asrock RX7900GRE Steel Legend OC will draw over 450w if I enable max power, even undervolted it pulls around 300w depending on the game.
I don't know how TPU does it TBH but there data base has a GPU spec sheet with a suggested PSU for every single GPU made for the last 20+ years so guessing they have some idea of what they are doing but, they are just basing it off the reference design. and aftermarket cards can be quite a bit more power hungry...Try the PSU calculator sites, they are random. Some say 650w and others are calling 1000w.
Had some crashes this evening. No issues with heat on the CPU or GPU, the SSD was toasty at the sensor 2.
Ran a CPU stress test and no issues then ran the stress test on AMD adrenaline with the same undervolt settings that have been applied for a while now and got a green screen then restart, it's -25mv, mem on fast timing and power limit on -1. Went back in and put the tuning to default and ran the stress test again and got a black screen and restart. Temps seem ok, nothing over 80, even on the hotspot and GPU memory. All drivers are upto date and have nothing running in the background as it's just a gaming pc.
Anyone else have any similar issues with the latest drivers?
Not sure tbh but I think off top of my head 8-10 yearsHow old was your PSU?
Superflower 1300W, 13 yrs old, never had any gpus coil whine and it started off life with 290X CrossFire...Out of curiosity i had a look when i bought my EVGA 650 GS PSU.... mid 2015, its 11 years old
Still works perfectly tho, i'm sad that EVGA are no more.![]()

That's quite the beast!This is what I'm rocking for last few months. I think I'm covered.
How far into the negative did you go?Reduce the Power Limit into negative if your having stability issues to reduce spikes/increase stability if you can't upgrade your PSU any time soon.
Ran a 79XTX undervolted AND a negative Power Limit on a 600w PSU Evga fine for months before a new psu was bought.

I've got an old Antec Quadro 850w was used for around 12years in a few different builds.Superflower 1300W, 13 yrs old, never had any gpus coil whine and it started off life with 290X CrossFire...
if we've jinxed it....
me n u r done.![]()
It will vary from card to card. My 7900GRE will go as low as -4 but I run it at -5 just to ensure full stability but I run a undervolt as well.How far into the negative did you go?
Ok thanks for the info. Will try mine at -30 to 49mv and a -4 PL. Just until I can pick up a new PSU.It will vary from card to card. My 7900GRE will go as low as -4 but I run it at -5 just to ensure full stability but I run a undervolt as well.
On that psu the XTX was -5 or -10 Power Limit depending on the game and fps, (I run per game profiles as they never reset to default) always runs an uv 1100 stock is 1175 iirc.How far into the negative did you go?
Ok another new lesson learned about the AMD Adrenaline, game profiles don't rest but the tuning section does, quite often lol.On that psu the XTX was -5 or -10 Power Limit depending on the game and fps, (I run per game profiles as they never reset to default) always runs an uv 1100 stock is 1175 iirc.
