PLEASE HELP psu compatibility

[Dgreen]

Hey guys and gals need some help again. So i have bought a evga gtx 1050 and was planning on also purchasing a psu but i have an older model dell PC that i dont use anymore and it has a 305w psu in it. The PC i will be putting the new gpu in is a HP 550 153 with a i3 4170 8gb ram 1tb hd. I know the recommended psu for a gtx 1050 is 300w. So my question is can i but the 305w psu from the older Dell in my HP they are the same size and the psu will fit in my HPs case but is that psu compatible with the HP i have. PLEASE HELP/RESPONDE

Yeah it should work.

 

IMO it's nicer to get a new PSU that you trust, but the dell PSU should work just fine.

Check whether the PCIe slot is x16 long electrically, which means the contact points (at the back of the mobo) goes as long as the slot's physical size. If it is, then you can use it. If it's not (half way through then it's 8x) then the slot can only give 25W of power, which isnt enough for the card to run properly. In that case, either the card slows down, or it just wont work.

 

So you have three options: Get a card with 6pin power connector so it can sip power there, but the problem is that this doesnt work all the time and your 305w unit might not have. The other option is use a low power card, like the 30w GT 1030 (should work, but again it's 30w v.s. 25w so it might not work either).

The last option is to get a new mobo, case and likely PSU, while reusing as much parts as possible. Cost the most, but it will work.

ok awesome thank you guys very much! my mobo does have the pcie express 3.0 x16 and the dell 305w psu does have a 6 pin pcie power connector. So the other thing i was wondering about is that the sata conector that is on the dell 305w psu has 4 wires on it and the connector that is on sata from the original psu has 5 is this a problem?

I'm not sure if you have done this yet, but i have to ask.

 

You want to replace the PSU you have with a 305W PSU to power your new GPU that pulls 300W?

In that case, where is the power for CPU, MB, RAM, drives need?

 

You want to use the 305W PSU along side the one you already have, dedicated the for GPU?

In that case you need a PSU splitter or use a jump starter on the PSU for the GPU itself. Or jibber-make-it with a switch to turn it on and off.

no the power consumption for the gpu is max 75w under full gameing load the company suggests a 300w psu for the hole system inlcluding gpu cpu mpbo and exc.

1. What PSU are you talking about?

2. Have you taken a look at the Connectors???
Are they both ATX compatible?? 

3. There are many Entry Level DELL/HP/Lenovo/Fujitsu machines that use propriatary +12V only PSU with either +12V Standby or +5V Standby...

 

And you don't need to replace the PSU anyway. Just use the original one.

And with _THAT Wattage_ its highly improbable that you can use an ATX one anyway and that it is one of those +12V Only units I was talking about.

 

@bob51zhang

Your statement could kill his Motherboard or worse.

You clearly don't know what you are talking about. Because there are some proprietary units used in many of those OEM machines...

sorry for the late reply been out of town on work but thank you very much for the info so im not sure how to tell if the the old dell psu is atx but im pretty sure that the one i am using is.So i was alittle worried about the sata cable not having the same 5 wires running to the plug like the one im currently using does... so i bought a new one a 450w evga and hookesd it up it is running everything great again thank you for the info and sorry for the longggg respond time!!
