hp pro desk 600 g3 gtx 1660super

[makemorewhisky]

I got a HP Prodesk 600 g3 with i5 6500 and a 250w PSU (platinum 80+), I was wondering if a GTX 1660 super could work on my system without any power supply problems

@makemorewhisky,

Welcome to our peer-to-peer HP Community Forum!

A GTX 1660 Super requires at the very least a 300-watt power supply equipped with one 8-pin PCIe power supply cable.

Your 250-watt power supply (p/n: 901760-002/901760-004) is not capable to power a GTX 1660 Super.

Assuming you have an HP ProDesk 600 G3 Microtower, you would have to upgrade your power supply with this 500-watt unit with p/n: 901759-003.

Hope this was helpful.

Kind Regards,

What about a gtx 1650 super and put a a sata to 6 pin adapter

@makemorewhisky,

A GTX 1650 Super has a 100-watt TDP, so that should* work.  I would recommend a dual 15-pin SATA to 6-pin PCIe power adapter cable:

* This is a at the very limit for a 250-watt power supply.

By the way, those dual sata to 8-pin adapters can only handle up to 72 watts.

Each sata cable has three 12v pins and each pin can only do 1.5 amps (18w).

In those sata-to-pcie power adapters, only two out of the three 12v pins are used.

So the max wattage you can pull from a dual sata power to 6-pin adapter is 72 watts.

12v @ 1.5a = 18 watts.

4 x 18w = 72 watts.

This limits you to a max of 147 watts for the video card due to:

PCIe slot = 75 watts

dual sata to 6-pin = 72 watts

147 watts total.

However the practical limit here is how much wattage you can push through the sata power motherboard header.

Each 12v pin on the sata power cable's motherboard header may max out at 103 or 108 watts total.

Your best bet is to get the large format 500w power supply for the HP Z2 G4 workstation.

You can flip over the power supply and reverse mount it or cut the case to fit it.
