Sunflower`s PCI-E x16 slot

Nikita_93 · ‎04-19-2020

Hello! I want to upgrade my RX 550 to RX570 or RX580, so 570/580 has interface PCI-E x16 3.0 version. I can`t find official information about PCI-E (version!) of Sunflower motherboard. I will be very grateful for this information! Or if somebody made this upgrade before - how does it work?

P.S. Sorry if i have some grammar mistakes. I`m not from eng-language country.

Thanks a lot!

Hi,

You can probably do a RX580 if it fits. You have the correct PCIe slot.

Your problem is the power supply. Per HP specs (Link) you have a 180 watt part now.

The RX580 (Link) needs a 500 watt PSU.

@wb2001 can help with the power supply.

@Nikita_93,

You can check the PCIEx16 slot with this program. It will list version.

The Sunflower requires an HP proprietary power supply unit. The RX580 needs the 400W version as a minimum.

HP part # L0461800-800 or # 942332-001. Both are 400W proprietary units. If you want the 500W version, it is part # L05757-800.

My spreadsheet verifying this.

Thanks @Grzwacz

Hi,

AMD recommends a 500 watt PSU per my (AMD) link.
