OEM upgrade route

[MasonCase]

1. Budget and Location

So I am trying to spend around 230 usd I am in Oklahoma

2. Aim

My aim right now is just to play fortnite without dropping below 60 FPS when I walk in circles.

3. Monitors

1 @ 1920x1080 60 fps

4. Peripherals 

Don’t need to purchase anything else

5. Why are you upgrading

Upgrading because I can’t play simple games like Fortnite, rocket league, and cs without pretty average performance 

 

———————————— 

I found an OEM was a really good price, I was planning on putting a gtx 660 in there and an 8 gb ram stick form what I already have.

 

The issue arises with their proprietary mobo. My 500 w EVGA psu can’t connect because the mobo has some wired thing going on instead of the regular 20/22/24 pin which could connect from my psu.

 

 

I figured I could just just run two psu’s until I can get a new Case/ mobo and throw everything together. Is this a good use of my time and money? Am I overlooking anything

You can get a power adapter for your power supply. Good luck!

Where at I haven’t found any

I don't know what your motherboard connector is and also don't know what your power supply connector is. I don't know if there is an adapter for it or not but if I know what the connectors are then I will try my best.

some guy mentioned the connections in this thread, I just have a 500 watt evga bronze psu so I have all the connections that come with that

This is what that forum said. In the forum people said it worked. 

 

"I just upgraded the power supply in one of these. Its not straight forward, but it can be done. The hp power supply is super bare bones and made just for the hp computer. There are no new power voltages, just different connections, so some rewiring needs to be done.

Here is what you will have to do...

Ill try to make this as less confusing as possible. The hp motherboard only cares about 3 connectors. And the wire colors are all over the place so I wont note them all.
1. 4 pin 12v power/common
2. 6 pin 12v/-12v power/common
3. 6 pin connector (smaller type), with only 4 pins/wires connected. (grey, wht, wht/red, and green)

Here is the breakdown for the above connectors, but with reference colors for the new power supply.
1. Just a regular 12v power connector. 2 yellow wires(12v) on the lock side and 2 black wires(common). Easy peasy.

2. A new power supply wont have a connector like this. This is where it starts to get tricky. You can use the other 4 pin 12 plug as you used in the first spot to start with. In the mb socket you can plug it in on the 4 pins on the right if you are looking at the mb with the lock on top. The two pins that are left will need 12v and -12v from the power supply. The 12v can be pulled from any yellow wire on the power supply. The -12 volt is usually only found on the main power plug which strangely isnt used on the HP 800. It is the blue wire. Its usually the 2nd wire in like in this diagram... http://cdn.overclock.net/d/da/da87333a_ATX24-1.jpeg . I found that my new power supply had an extra 2 pin connector that fit perfectly. It had 2 black wires in it that can be cut and spliced with the blue and yellow wires to be plugged into the motherboard. So, this plug when complete should have all 12v on the lock side of the plug and 2 commons and 1 -12v on the other side.

3. Ok, so this one took a bit of DMM work to figure out but here it is. This plug has 4 wires in the 6 pin small connector. The hp wires are green/grey - power supply on/off, and white, wht/red which are fan speed and fan control. There is no fan power being that the fan is already mounted to the power supply and integrated. I tried to us the typical green ps/on wire and ground from the power supply main connector, but it just doesn't seem to act right and wont boot. So what I found that works best is if you just splice a 5v red wire from your new power supply to the green hp wire, and a black common wire to the grey hp wire it works best. You will need to put a jumper wire in your power supply main connector from grn #16 to black common on your new power supply and just tape it up so the power supply will run. (This connection has to be made to run the power supply and its usually kind of tied to the power button of the computer). Just jump it and wrap it up nicely in electrical tape, it will be fine.

So at this point the computer will fire up and run just perfectly. Connect whatever video card you want and go. Just be aware that there is a big fat usb connector somewhat in the way. I happend to use a Asus 660 and the usb plug fit in a opening in the card. Perhaps more will be like that. ( http://xtreview.com/images/asus%20GeForce%20GTX%20660%20Ti%20DirectCU%20II%20TOP%20%201.jpg ). 

Sooooo, the only other pain in the butt is that the 2 wires we didnt connect add some issues. Actually just an annoyance. The control wire doesnt really matter, but the fan "tac sensor" wire being disconnected throws up an alarm during booting that something like "515 Chassis fan not working". It requires the pressing of F1 during booting. This is a pulse signal from the fan, it cant really be faked easily. The best thing to do would be to use the pulse output of the other case fan on the back of the computer and wire into this location. It wont control it, but it will make the alarm go away.

Anyways, I hope you benefit from my hard work. Its not a huge pain, just splicing some wires and should only take 20 minutes or so.

Okay my head officially hurts following that

Me too. Other than that I have no other advice and solutions. Sorry if I could not help. Have a nice day!
