Looking to be reassured on PSU debate

post #1 of 8
Thread Starter 
A friend of mine received a Radeon HD4850 and needed a new PSU. He ordered a http://www.newegg.com/Product/Product.aspx?Item=N82E16817170010 PSU (not consulting me!)

He powered the unit on (had to use a 2 molex to 6 pin adapter) and has problems with the display. After a minute or two he says he "losses display / signal".
I told him that his PSU was junk and to get something such as the Neo Eco 400 (what I use in my build). Do you guys think he was getting under powered by that PSU?

I'm on a HD5770, but I assume the 4850 uses more power as it's less efficient.

The PSU isn't too bad. 25A on the +12V should have at least run it on idle.

Tell him to test it on another PSU, with a higher amperage on the 12V line. If it still acts the same, the molex pin adapter might be the problem. I remember installing a graphics card which only worked if 1 of the 6pins was plugged in.

The PSU should have enough wattage. The problem is most likely the 4-pin molex to 6-pin PCIe power adapter.
 

 

Edit:

 

If he gets "losses display / signal" on desktop unlikely the PSU wattage.

I would agree that adapters like that are very hit and miss. The PSU listed is rated for enough wattage/amperage on the 12v, however lower-end PSUs are a tricky thing as quality is not always the greatest. As others have suggested, do you or he have an alternate PSU to test with?

According to the PSU label below:

17-170-010-S03?$S640W$

It's only a 400W unit, and AMD's website recommends 450W. I'd say that's pretty clear.

try removing unnecessary stuff for testing the gpu and psu.

remove the optical drive, extra hdd, and extra fans.
If the gpu runs fine then its the psu's fault.

Logisys is a crappy PSU manufacturers. There is one review from Hardware Review that talked about 650W unit from Logisys that can only do 300W before it burned itself out.

So yes, I believe that PSU is severely underpowered.
