Question 1

What does the switch on the back do? I can't find the manual.

Accepted Answer

The switch on the back changes the input from 115v to 230v. If you live in the United States it should be set to 115v but if you're somewhere else then you should see what standard your country uses.

Question 2

does this have an 8 pin power cpu connector?

Accepted Answer

I think this PSU has a 6 pin one but i don't recommend this PSU. This lasted me half a year until it fries my gpu and mobo. I recommend save a little more money to get another psu like a corsair one.Always remember that the quality of the PSU matters or your house will burn.

Question 3

My Case is to small, can it sit outside my computer or is that to unsafe?

Accepted Answer

It would work most likely, but is not recommended. Try to make some sort of wire or bracket to ground the case of the power supply to the pc case if you do plan to run it that way. Just a copper wire from scare hole to scare hole will work if properly secured.

Question 4

i dont have much room in my case and currently the power source i have has only one fan for exhaust.  Can you run this power supply where the big fan is on the bottom and it not hurt anything?

Accepted Answer

My pc seems fine with a similar setup. Only other fan is the one for the graphics card.  Sometimes noisy though.

Question 5

I a,m actually looking for psu for an ASUS that is 400W that also has 400BB not sure much about comp system. What is compatible to this psu? can someone help?

Accepted Answer

You should be able to use this one no problem, I use this psu on an ASUS motherboard and it works beautifully.

Question 6

Does this have a molex connector?

Accepted Answer

Yes there are two 4 pin molex connectors on this power supply. Zero mini-Molex connectors that 3.5 floppies or old card readers use--you'd need an adapter for those.

Question 7

would this fir inside my hp pavillion 510 p010 case?

Accepted Answer

You'll want to measure your current unit for dimensions. I'm seeing contrary numbers online so it's hard to say if you need a standard atx, or a smaller uatx or sfx model.

Question 8

would this be able to be put in a dell optiplex 990?

Accepted Answer

no. you need a mini power supply--https://www.newegg.com/Product/Product.aspx?Item=9SIA85V3J88620&ignorebbr=1&nm_mc=KNC-GoogleMKP-PC&cm_mmc=KNC-GoogleMKP-PC-_-pla-_-Power+Supplies-_-9SIA85V3J88620&gclid=Cj0KCQjw5LbWBRDCARIsALAbcOeYqUMHXvLKPV_Q7HpN-DbIirZbomMiVuM0AGAiRooVZficcS-qzqUaAhT5EALw_wcB&gclsrc=aw.ds

Question 9

Will this power an amd fx 6300+gtx960 4gb without issues?

Accepted Answer

I would reccomend a 500 watt psu. Mine has a 4440s and a gtx 960 and 16gb of ram and the max energy it would push is 350.

Question 10

I'm in the market for a new power supply since my old one died, so I was wondering how long are the 4 pin CPU power cable and the motherboard power cable? I am using a case that has a slot for a power supply in the basement and a Micro Atx Board and the slot for both is very high.  So I want to be sure that the cables can reach before I purchase the psu.

Accepted Answer

12-16 inches is normal but you can get extensions for a couple of bucks for full towers.
