Is it safe to add a 6-pin connector (adapter) to a 600 watt psu?

decepticon2 · Jun 3, 2015

I tested the average watts that my computer draws and it is very low. I have a 600 watt powersupply, but it only came with 1-6 pin connector for video cards. I need 2 six pin connectors for 1 video card.

I don't have experience with this so I was wondering if a psu comes with 1-6pin connector, if there is a safety reason for it and etc. So I thought I would ask here.

What PSU and GPUs do you have? Also you can get an adapter for molex to 6 pin.

Low quality/low power/old power supplies usually only come with 1 connector.
It would be safe to use 2x Molex to 1x 6-pin PCI-E adapter but it does have few little safety problems with it on low quality psu.

It all depends if the PSU can output the amount of power the card needs on the 12V rail, and if the PSU is of decent quality.

It is a COOLMAX V-600, 600 watt power supply and I would like to run a XFX R9 270X video card. The video card has 6 pin 2 connectors.

The power supply has x 1 PCI-E and I have 2 molex connectors left to add one of those PCI-E adapters. It is a cheap power supply, but so far it's not bad at all. Also it has a silent fan, so it's a plus.

Right now, without the video card (using a simple Radeon video card that requires no additional power). My total wattage drawn from the wall is extremely low. It fluctuates around 99 - 129 watts. I tried a NVIDIA 560 GTX on a different computer, with similar characteristics and the highest it went was around 140 watts. I don't know all this stuff, so I'm not sure I understand, why manufacturers require 550 watt psu minimums and etc. Maybe someone can clarify this for me.

I'm using a Kill-a-watt monitor to get the readings. Very accurate from what I understand.

Coolmax makes very low quality power supplies. You should replace it asap. Any good quality power supply in 600 watt range will have 2 PCIe connectors or more. No, it would not be safe to add a 6-pin PCIe connector to such a poor PSU.

decepticon2 :

It's because under full load, they can take somewhere around 200-300W.
When you had the GTX560, you probably didn't have it running even nearly at max.
At which point your system would draw around 400W.
