[SOLVED] MSI R9 390 Gaming with molex

[TarikS]

Hi guys and girls,
I am planning on upgrading my rx 460 to an MSI R9 390 GAMING card. But I have a question. On my PSU I have a 6 pin connector and 2 molex connectors. I do not have an 8 pin. So I was wondering if I could buy a molex to 8 pin converter and use that. Buying a new PSU is out of my budget because I am a student and I do not wanna ask my parents for money. Can you guys anwser as soon as possible.
Thank you all!

R9 390 is a beefy card, it takes lots of power. List the PSU and system spec first.

Although you haven't provided much info about your current PSU, it is usually recommended not to use any kind of power adaptors for graphics cards.

If the PSU doesn't have the neccessary connectors for the hardware, it is often a strong indication that the PSU is old, has inadecquate performance, or is one of poor quality - all are important reasons to upgrade the PSU to one of good quality and meets the power requirements of the system it will be installed in.

Why would you buy a new graphics card and run the risk that it can potentially be damaged by the PSU? That would put you in a worse situation than you are now, at least you have a working PC

The psu is some rhombu tech atx650hm but so far I had no problems with it. It has a big fan.

I would not proceed with your planned upgrade if you do not upgrade the PSU.

The size of the fan says nothing about the quality at all, and a quick search on Google indicates that even the fan is probably of questionable quality.

I wouldn't even use the PSU with your current setup, but pushing it even more with your planned upgrade would be very risky, in my opinion

A 650 watt PSU with only one 6-pin connector does make me question the quality or the age of the PSU

From the link, I can see that it is promised to deliver up to 28A over the 12V rail. The GPU takes ~280W which is ~23A so you only have 5A@12V rail (60W) available for the rest of the components. It is very slim. Get another one.

It might be a "name brand" but it's still junk and not going to reliable power a 390.
