Quick psu question

[muffinman84]

Upgrading my gpu and i noticed somethin worrying. My gpu requires 38A on12V and has a 6pin slot. My psu states it has two rails, 12v1 with 20A and 12v2 with 20A (2 separate 6 pin connectors). Will it work and should I try it or is it best to not even bother and get a better psu? Gpu in question is nvidia 960 gtx strix and the psu is Lc600h-12 (by lc or lg power). Quick answer would be appreciated since the rig is already disasembled.

The psu lists its 600W power as peak rather than continuous. Don't bother with it and get a Seasonic or EVGA.

38amps is what combined railed need to have! Yours does have combined 480watts or 40amps. Quality of the unit is not high though.

 

[muffinman84]

But since i can only connect one rail will it still be enough? Also since i already have this power supply what's the worst that can happen if I try to connect anyway?

 

[rohitbaran]

The worst that can happen is that it will kill your gpu and the psu could burst in flames.

 

[rolli59]

Yes it should be plenty 20 amps is 240watts plus it gets 75 watts through the PCIe slot. You did not specify what card you have but a 6 pin connector delivers 75 watts and a 8pin 150watts.

 

[muffinman84]

Geforce gtx960 (asus, strix). I can only connect 6pin one which means 75w from slot + 75w from 6pin =150w but the card specifies that it needs abit over 200w. So is it still enough? Sorry but I really don't know jack about this stuff and electricty is a mystery to me.. Far as i know the nightmare described above could really happen :S

 

[rohitbaran]

So just go ahead and buy a better psu. That's all I can suggest. If you want to take the risk, well it's up to you.

If the card has two connectors they have to be both connected with appropriate connectors. Looking at pictures of that card it appears to have only 1 six pin so you will be fine.

 

[muffinman84]

Yeah it ony has one 6-pin. But won't that deliver only half the power? I will most likely boy a new PSU now anyways, but thanks for the answers. One addional thing: when looking for a new psu to buy, is it better to stick to 1 rail then? It needs to specify that it has one 12v 38a+ right?

 

[rohitbaran]

It is not necessarily better to have one rail, but yes, in most situations, it is the better choice.

The card will not hit 150watts max which explains the 1 x 6 pin http://www.techpowerup.com/reviews/ASUS/GTX_960_STRIX_OC/27.html

 

[rolli59]

GTX960 is has a recommended PSU size of 430watts, Your 600watt can handle it although not the best. If you upgrade a quality 550watt is what I would get. EVGA and XFX make some rely nice offerings.

Ok, so I've been looking into what I can get around here (it needs to be in stock since i can't wait on deliver and it takes way too long to get here). Can anyone advise me if either of these two is good enough:

http://www.xilence.de/en/products/power-supplies/performance-a-series/performance-a-series.html (the 630W one)

Thanks!

 

[rolli59]

Just stick to you current one those are similar in quality.

Thanks!

Sure, get one of those to get you by for now, but I would not use them for a prolonged basis. I would only use them long enough until you can spring for an EVGA or Seasonic...or even a tier 1 Corsair.

Well the only one availible in my budget would be http://www.mlacom.si/evga-600w-bronze

This better or should I still stick with the existing one?

Existing one, that is a budget PSU may be a little better than yours but not considered quality just OK.

 

[DSzymborski]

If you don't have the budget to buy a safe power supply that delivers clean power to your components, I'd just return the 960 and get a 750ti, which a junk 600W power supply will usually handle (a lot of junk 600W are only just mediocre if you use them as if they were 300W power supplies).

The power supply is the most important part of your PC. It's like buying a used car with damaged brakes - if you don't have the budget to fix the brakes in addition to buying the car, you don't actually have the budget to buy the car.

 

[muffinman84]

One last follow up, I got a bit of a christmas bonus so my budget went up a bit Unfortuantely, I can still only get what they have in stock, so my question is weather this would do the trick(is worth getting for my setup): http://www.antec.com/product.php?id=706875&fid=5022132&lan=nz

Apparently the better brands (EVGA, Seasonic, etc.) are never in stock around here.

 

[muffinman84]

Or this one second hand: Seasonic G-series 550W GOLD

 

[rolli59]

Either the Seasonic or the Antec above will do the job, both are quality units!

 

[muffinman84]

Thanks for your input. I decided for the Seasonic one since it's cheaper second hand and still has a 5 year warranty left.
