275w PSU with 1060 3GB

I bought a computer with a 275w PSU and a 1060gtx (3GB) from a reputable seller. I'm thinking, though... he said it doesn't go above 190w at full load when the GPU is at 100%. Can anyone comment on this and tell me if I absolutely need a new power supply?

 

Well, the GPU itself tops out around 120W (stock speeds), so if the PSU can output enough amps on the +12V rail, it should be fine. Though most PSU calculators I've used would recommend at least a 300-350W PSU for that and a reasonable CPU.

 

CPU is an i7 3770

 

That CPU has a TDP of 77W. So with a 275W PSU, I'm surprised you're able to do anything but idle with that computer...

I'd replace that PSU with a quality 400-450W unit, maybe more if you plan on overclocking.

 

The chassis is a dell Optiplex 9010 so I don't know what will fit. If a 400w will fit I will absolutely replace it.

 

Looks like you got sold a bill of goods.

 

I cancelled the order lol

 

Aside from building the desktop yourself (very simple, and really a lot of fun imo), there should be plenty of sellers who know what they're doing and/or not selling you shoddy hardware. At the very least, you sill have the major OEMs.

 

Went with an i7 4790, 1060gtx (6gb rather than the previous 3gb) and a 400w psu

 

I'm having trouble installing this GPU. It's been a decade since I installed my last one (8800gts) and I have no clue where to plug the card into the PSU... It came with a short pci cable but there's no corresponding PSU cable to plug to..

What I'm trying to say is there is no molex connector on the PSU.. never seen this before. It's 400w

 

PSUs don't come with Molex connectors. They usually have some combination of 6-pin and/or 8-pin PCIe power connectors. Looks like your 1060 comes with either a single 6-pin or 8-pin socket (hard to tell in the picture), so see if your PSU has a corresponding plug.

 

It doesn't. Just sata

Is there some adapter I need?

GPU has 8 pin

 

Happen to have the PSU model name/number/whatever?

 

It's a Logysis 400W ATX power supply. I have no desire to replace this PSU based on how they tied all of the wires. Such a pain

I think I'll return it.
Was expecting to play BF1 tonight, this is so disappointing.

If I keep everything, what PSU is recommended with an 8 pin connector?

 

Wattage is important to an extent, sure, but you also need to pay attention to what connectors are offered (you now see why) and what the power ratings are on each rail (particularly the +12V rail). For a gtx 1060, 20A or better on the +12V rail and a total power rating of 400W or better will be fine.

 

Thanks man, I appreciate the help. It's lonely out here, but I always appreciate those willing to help out.
I take it, this would suffice? https://www.amazon.com/gp/product/B018JYHBE6/ref=ox_sc_act_title_2?ie=UTF8&psc=1&smid=ATVPDKIKX0DER

 

Whenever I look into buying a PSU, I typically refer to a PSU calculator to help me with what sort of specs I should look for. An example I use is this: http://outervision.com/power-supply-calculator

Given that you're running an i7-3770 and a GTX 1060, your load wattage will be 275W (the seller probably got confused by this number) and a recommended wattage of at least 325W. PSUs with at least a 80+ Bronze rating will waste up to 20% of their wattage as heat, so to stay on the safe side while at the same time allowing you some headroom for tweaking GPU clocks to a degree, I'd look into something in the 400W-450W range at most. Buying something with a far higher wattage is not only not necessary, but will also cost you more in the long run (PSUs are less efficient when they're barely loaded, as well as when they're fully-loaded; you ideally want to have your load wattage to be around half of the PSU's rating).

Personally, I'm really picky when it comes to PSUs since a bad PSU can fry the entire system if it develops a problem. That said, I haven't bought any EVGA PSUs before, so I can't vouch for that PSU (though their GPUs are good). I've used Corsair and Seasonic in my previous builds, so you could look into those brands.

For example, here's a Corsair CX-M 450 for $40: http://www.newegg.com/Product/Produ...46&cm_re=corsair_cx450-_-17-139-146-_-Product . 450W, 37A on the 12V rail, and as a bonus it's semi-modular, so your cable management will be a bit easier.

 

Thanks. I should clarify I am running a 4790, not the original 3770.

Also since the GPU has 8 pin shouldn't I get a PSU with an 8 pin connector?

 

With that CPU, that bumps the load wattage up to 282W and a recommended wattage of 332W or better, with at least 21.2A on the 12V rail. The posted PSU still meets those specs.

It also has an 8-pin PSU connector (the 6+2 pin connector in the specs); you just snap the two parts of the plug together if you need the 8 pins.

 

Oh, nice. You sure 500w isn't better? Sounds like you know your stuff but from what I've read people with the 1060 are going for higher wattage.

I plan on doing a bit of OCing

 

If you're planning on OCing, it would certainly be nice to have the headroom a 500W PSU would provide.

 

Are you able to tell if this has an 8 pin connector?

Seems to have 2 of them: http://www.evga.com/Products/Product.aspx?pn=100-B1-0500-KR

 

Wow you've been a huge help. I cannot wait to swap out the PSU on Saturday. Hopefully all will go well. Afaik all I have to unplug are the cables connecting to the mobo and CPU. There isnt any SSD installed yet

 

Just got the new PSU. The problem is taking out the old one. The rig is currently barebones so there isnt much installed, but there are wires everywhere. They go around through the back and are ziptied. I guess i just need to cut all the zip ties..?

 

Yep. Obviously don't cut any of the wires in the process.

 

Got all that done. My biggest issue is installing the SSD lol. It's 2.5 in but i bought the 3.5 adapter. I cant seem to get more than 1 screw into both the fixture and case

Ok just installed all the hardware. Upon pressing the power button the computer doesnt start. Thought i had the PSU fully hooked up. Hmmm


This came with the PSU. Is it necessary?

I only remember connecting the major big square pin cable to the mobo and nothing else. Instructions say connect 20+4 as well as 4+4 pin eps12v .. what is that?

 

Can't really tell what that is supposed to be from the picture. However, the eps12v is your CPU power connection.

 

CPU has power. The picture is the tester that you plug onto the other end to see if the PSU works. It's simply not turning on despite all the proper connections

Good news, unplugged all connections and got the fan spinning. I initially plugged in all the same cables that the old PSU used so im kinda stumped

Damnit, I think it's the motherboard. Tested all connections with the PSU tester and I get power, but not when the PSU is plugged into the mobo.



This cable goes around to the back of the case into here.


It ties into a bunch of things but it didn't come with the psu. Not sure if i should keep it plugged in

Computer starts now but I get no screen. It then turns off, then comes back on, but no screen, still. What's this indicative of

Is it because the ram doesnt line up with the slot on the mobo?


Note the centimeter gap between where the lines should meet

(You can disregard all previous posts)

 

You should reseat your RAM... I had a lot of issues with the damm RAM, it came loose when shipping and caused a lot of issues..

It's DDR4 and it's actually incompatible so I am getting DDR3 CL9 today and will try that.

 

Ok I hope you didn't break the slot when trying to put it in.. Pin layouts between the 2 are totally different..

Nah, looks just like it did before I tried putting the memory in. Unless there's microscopic damage, which I doubt.

 

Let us know how it goes when you put the proper RAM in..

It worked!!!! We are rolling folks

 

Great news! Have fun with your new computer!
