Upgrading my graphics card

Recommended Posts

Posted · Original PosterOP

So I decided to upgrade my gtx 745 to Rx 570. Unfortunately I don’t have 8pin connector from PSU so I decided to remove 15 pin sata from CD drive and use it with an converter. I was doing it with a friend, the converter needed a 2 15pin sata connector to power 1 8-pin GPU connector. My friend removed the sata power from the hard drive and tried to run it like that (I know he doesn’t know a thing). After that, I reconnected HDD but pc doesn’t post at all. There is a weird buzzing sound comes out of motherboard. Idk what is wrong. I have i-4770, 12gb of ddr3 ram, and plenty juice for GPU from PSU(about 500w). It makes the same noise with my gtx 745, intel onboard graphics as well.

And this, dear reader, is why we don't use cheap adapters with ultra low quality power supplies. 

 

Try a different power supply or motherboard. Something got toasted

I would agree with 5x5 the PSU.  But imo more so that then the mobo.  just my 2 cents and what not.

one SATA connector used when 2 was needed, and on an RX 580 no less, which utilizes the entire 150 watts an 8 pin affords. SATA and molex, commonly used to adapt to PCIe on super cheap systems, simply cannot handle the current.

 

Sounds a lot like a dead PSU, rip in pasta. In the future, mind the connectors. If your PSU lacks the connectors needed to run your hardware, it's not up to the task, and no amount of adapters will change that.


I WILL find your ITX build thread, and I WILL recommend the SIlverstone Sugo SG13B

 

Primary PC:

Draws 400 watts under max load, for reference.

Dual Xeon X5560 - 24GB ECC DDR3 - GTX 750 TI - old Seagate 1.5TB HDD - Dark moded Ubuntu (and Win7, cuz why not)

 

EVGA G3 thread, BR/BT threadSeasonic Focus thread, S12II/M12II thread, Userbenchmark (Et al.) is trash explained
