Re: Richtek rt8249c equivalent !
Not an equivalent - RT8249C has pin 19 as SKIPSEL (PWM Operating Mode Selection) and TPS51225C has pin 19 as VCLK (Charge Pump Output Clock). TPS51225C is only an equivalent to RT8249A/B and RT6585A/B. It is however possible to use TPS51225C in place of RT8249C but it is required to cut off pad 19 underneath the IC to separate the circuit from pin 19.Last edited by SERGEY1962; 03-22-2022, 01:08 PM.Comment

it's equivalent to RT6575b but you need remove 19 pin of pad.
RT6575=RT8249C =2Q (and 2N= by remove pin 19 on pad).Comment

so i took out one of my spare gigabyte ep35-ds3r mobos from storage for use to do some cpu, ram and video card testing of stuff i bought from ebay and got for free from momaka. he bought 50 e8400 cpus for cheap from ebay some years ago and i decided to help him relieve him of some of his supply since he had waaaay too many!!
what did we say about hoarding too much stuff and depriving others of them?! *cough* socialism *cough* lol! 
i had to blow some dust off the board and heatsinks with the datavac as i didnt clean it up before putting it in storage. after finishing... -
hi guys,
this one only has a boardview and I can see 3.3VA_EC pulsing (as is PU8701 3VAO+) along with the power led. I injected 3.3V on that line but nothing warms up (0.01A draw) except the EC slightly which can be normal.
I tried another bios incase it is related somehow and a 51225C (dont have rt8249C in stock, https://www.badcaps.net/forum/troubl...35#post1637735) with pin19 isolated (and also connected) - same result.

Hello guys,
I have interesting problem. My MoBo MSI running on Ryzen 7 w/o graphics just good. I swapped to Ryzen 5 5600G and on the boot I stuck with screen on picture. Enter Password. I checked BIOS setting with Ryzen 7, no security is enabled, BIOS password or TPM.
BIOS I updated to last one.
any suggestions?
And same thing for two different 5600G, and yes, MoBo supposed to support it.
Thank you... -
Hi guys,
I have a friend's Dell 3779 that came to me with severely shorted mobo. Did not manage to isolate the cause, most likely that was a bga shorted. Went for a replacement motherboard. Got one from China, apparently it's been tested prior to shipping. The mobo starts up normally but I am getting no display whatsoever.
Tried using external monitor, but being blind I am not sure if laptops goes as far as booting to Windows, a d without it I cannot get hdmi to work. Can't see boot menu options to make sure it boots to Windows. Went ahead and did a blind bios update,... -
HI I have a PC using a Corsair cx600 psu & ASRock B450 Pro4 mother board that won't power on after a shutdown (replaced a dead drive in a raid array) Not the boot drive.
With most things unplugged, including the 24 pin ATX connector, but not the ATX12v to cpu, I have +5.01V on the +5vsb pin 9 from the PSU. When I plug the 24 pin back in to the mobo, the +5vsb fluctuates between 1.1v & 1.9v.
Not sure where to go from here ?
Is the PSU at fault or is the mobo causing the problem
Look forward to any help :-)
If I plug the 24...
