12v rail question

zlawson13 · Apr 12, 2014

I was building a computer for a friend, and I notice that I do not have an 8 pin connector for the 12v for the cpu... I was wondering if I need it with a 600w power supply?

Here is the specs,

SOLIDG SDGR-600BX 600W ATX PSU

GIGABYTE **R7-250OC 1GB D5 PCIE DV

GIGABYTE GA-78LMT-USB3 MATX

AMD FX-4130 BLACK

DIABLOT EVO ATX MID-TOWER CASE

CRUCIAL 4GB D3 1600 DIMM CL9

WD 500GB 2.5 SATA 3GB/S

Solidgear makes poor power supplies.

I know, but he was on a very tight budget...any ideas?

That build is quite poor in almost every aspect. How much did your friend spend on that? Can it be returned?

That isn't really a 600 watt supply it's more like 408 Watts , and only 34 amps on the 12v rail , which is exaggerated also.

Yes, you will need those 12V rails because they supply extra power to the heaviest components (CPU, GPU.)

You could try something like this but I'm honestly not certain to expect success or not: 8 Pin Converter

hi zlawson 13,
yes you will definately need the 12v 8pin eps cable ,
there is an alternative , you can get a molex to 12v 8pin eps cable and hook it up to one of the molexes coming from the lead on your psu , that will get you out of trouble , such as this ,

He bought it at microcenter, I believe they have a return policy...

I believe you need a 4-pin to 8-pin adapter:

There appears to be sufficient power for your CPU, so I believe this will work but contact Solidgear to verify this is the correct cable, AND that there would be no issues with your FX-4100.

I went to the webpage and they claim "supports all modern CPU's" or similar which is pretty much crap if you need an adapter.

Most Power Supplies have an 8-pin connector comprised of two smaller 4-pin connectors so you can use either 4 or 8-pin depending on the motherboard.

it turns on pretty smoothly, but I'm not running it, I don't think I like the idea...

A 650 watt power supply that is sold at SEARS for $30.00 is not worth using and may damage your other components.

Made by the best = SEASONIC , with 44 amps on the 12v rail.

Any ideas on microcenter?

I'm going to take it back tomorrow.

This is a decent budget power supply with 40 amps on the 12 v rail.

zlawson13 · Apr 12, 2014

2 - matching 4gb modules of memory would be better for gaming and would help it to run in dual channel mode.
