GTX 780 ti and 600w PSU

[jak731]

The VDDC current is not the draw from the 12V, it's what it's delivering after reducing the voltage, in the last screenshot it even states the output voltage, 1.213V. 1.213*137.3=167W, not 1.6kW. 167W is around 14A at 12V in case you were wondering.

The builder series is low end but should work.

If that's correct then it means the 780 Ti @ 1.4v posted above only uses 97 watts?

GTX780 Ti alone will draw around 250W whilst gaming for a short period of time. 300W + under heavy load (GPU Boost 2.0 kicking in for instance to boost FPS @ heavy GPU loads).

If you manually overclock GTX780 Ti can draw up to 372W when heavily overclocked however

This is without anything else so throw in another 250-300W on the safe side before you include the CPU (overkill I know but a rough guide). So this takes you up to 600W excluding the CPU which again could be around 300W especially if its heavily overclocked that takes you to around 900W so a 1000W decent PSU is a good guide but you can if you know what your doing get away with a very decent high end 750W model if you only have SSD's & a small number of case fans & do not overclock your CPU. £130 ish can get a very good 750W model

Time & time again the no1 mistake PC gamers make is to skimp on the PSU as power is power right .

In hot weather your PSU is under even more load due to the ambient air temps so depending on your rig & how long its on you can still get PSU issues as the PSU fan draws power & the other components do not usually work as efficiently unless water cooled so you lose overall system performance on a very hot summers day this puts more load on the PSU rails again if that's a weak component & on the limit it will either shutdown if overloaded (best case scenario on a decent PSU that's what they are designed for with superior shutdown protection circuitry) or blow something very expensive so your left with a new PSU & whatever else it blew some lose the lot (CPU/GPU get fried so does the mobo & Ram usually).

It hurts the wallet but a decent PSU is the only way to avoid denting your wallet further if you have a PSU failure due to using a cheap model (most have terrible overvoltage protection circuitry) they are really designed for low use business machines not highly stressed PC gaming rigs.

430 watts with a MSI 780ti Gaming at 1197Mhz that's with my cpu at stock, in heaven 4.0 benchmark.

Got anything else connected to the wattage monitor? If not must be the gpu oc taking its toll

Yeah you are right, I posted that while in Asda lol, forgot I had these also attached to the Kill a Watt Meter.

50 Watts = NEC 24WMGX3 24" TFT.
09 Watts = Virgin Media Super Hub.

So call it around 370 watts, quite impressed with that to be honest.

The PSU is your No1 component in my view poeple spend a fortune on a CPU+GPU's and skimp on a descent PSU.

Then they wonder why they have problems with stability and overclocking.

When l built my X58 i7 920:4.2ghz + 5870 OC'd as well 4 years ago, l bought a HX850W PSU. Never had any trouble maintaining my 920:4.2ghz at the same voltage during this time at 1.32v CPU-Z and knowing l would at some point go SLI/Xfire.

Which l did last year SLI 670's:1240/1745 depending on the benchmark + 920:4.2ghz, NO problems at all what ever the benchmark.

The Corsair HX850w cost about £155 4 years ago money well spent and its still going strong running 930:4.0ghz + a Toxic6950/70 Dual Bios custom cooled.

Have just upgraded to a 4820K:4.6GHz + Sli 670'S OC'd custom cooled run 24/7 by a EVGA G2 1000W Gold PSU £150, no problems with stability and overclocking.

So buiding a High End PC do not Skimp on your PSU, l could have got away with a 850w Gold 80+, but rather have a bit more in reserve to run at least a 780 TI.

So my No 1 Rule is do not skimp on your PSU for stability, overclocking if you do you'll have to buy another one so its False Economy as well.

Hope your HX850W lasts mate I had the HX750W which blew totally about a year ago luckily it did not take anything with it just the PSU went bang without warning. Corsair wanted me to return to their RMA center in Europe @ my cost (£60 ish due to weight recorded). This makes their long warranty a farce if you buy from OCUK nowadays they handle the RMA but everywhere else expects you to pay for RMA P&P

Obviously I will not be buying Corsair again as they were quite rude when I asked them if they thought it was reasonable for me to pay P&P after only 18 months useage

Even better when you take 10% off for efficiency so really only a load of ~340w.

Hi unlucky m8, l had a HX620W that went pop took out the mobo+cpu this has not put me of Corsair. As l bought the HX850W not long after that, but agree they should pay both ways or at least have a deal with a Delivery company so its cheap at least or pay half.

The HX850 is just over 4 years old and still going strong, using a EVGA 1000W Gold PSU on latest Build as it was on a OCUK 1 week only price.

One or two also have complained about this in the past, l believe OCUK helped out, you returned the PSU to them and they retuned it with other faulty Corsair PSU's if l remember rightly.

Its always worth ringing OCUK even just out of warrenty as they can offer advice and in some cases help out.

HX850 here, bought secondhand about 5 years ago. Certainly got value for money from it. Its been used with several highly clocked cpu's and a few sli setups, most power hungry being an i7 920 @4.2ghz with oc'd sli gtx 470's, 630w at the wall in games with that setup. 860w and climbing running p95 small fft and furmark extreme burn simultaneously. Ill be going 780 sli at some point on the spec in sig so may have to look into replacing the old girl as she's had a pretty hard life.

Sorry if this has been said as i was to lazy to read through the thread

Your PSU is not the best, is a cheap low end product, most PSU can do more than the rated wattage but better quality the psu they longer it would be able to sustain it for

just as not all PSU are the same, the same can be said for your GPU, some may draw more watts than others

If you have not already then you could reset your overclocks, and remove any devices that require power like sound card, rom drives and fans as much as you can and see if that helps

failing that get the best psu you can afford and alway get a few 100watts more than you need, as you never know when you need it

Not saying that for the opening poster the PSU isn't the issue, but some of the responses in this thread seem very harsh, If he had of bought a no name brand £25 PSU then those responses would be all good and well, but he didn't he has a £60 600w good named brand PSU.

 

[Nige_B]

It's fair comment to be honest. As I'd never built a system from scratch before, and was offered a build at a cheaper rate than what I'd build it for myself I went for that option. He specced it to my requirements at the time, however I did make it clear that I did intend to upgrade in the future. He obviously overlooked the PSU, and obviously so did I!

I did read up whether a 600w PSU would cope before ordering the 780ti, however not my specific PSU. So all in all I suppose I deserve some criticism.

I've ordered an XFX 1000W Gold Standard unit so hopefully this will resolve the issue!

I think you should have tried a few other things before getting a new psu. In theory the corsair cx600 should handle your pc just fine even with 480w on the 12v rail.

If it doesn't then I'd RMA it.

It's little better than a cheap no name unit though. It has cheap internals and a crap spec. Only 480w on the 12v rail of a 600w psu is abysmal these days. Corsair established themselves with high quality Seasonic units then once established swapped to cheaper oems and inferior units while keeping the prices high. At the same time they also slashed the warranty length. The Original CX400 was a cracking unit but then was replaced with the garbage builder series with massively inferior specs. Personally I would never recommend a CX series psu and rarely any Corsair psu.

you think, mate you need to understand just how PSU delivers power, there is a reason they come in 4 flavours, a 600W bronze is not a match for a 600W platinum, hence why they are 3 times the price, there is more than one reason why a 600W bronze might not be cutting it regardless of the brand, and then there is age to to consider, cheap psu equals cheap capacitors which degrades over time, which psu do you think will degrade the quickest? the bronze or the platinium? so if his PSU is a year old it wont be delivering the same wattage that it did when it was brand new, and each year it will be less wattage than the year before, the harder you work it the quicker it will degrade, overclocking wont help the cause either, world record benchmarks are not achieved using a Corsair CX600, these are made for low end basic budget system builds, not for extreme overclocking and high end GPUs with all the bells and whistles, so fail to see why the simple truth very harsh at all

The cx600 isn't made for low end basic budget systems otherwise it wouldn't come with enough pci-e cables to power high end graphics cards. You could argue the cx430 is, although many people even use that with cards such as the 7850/gtx 660 because its capable of doing so.

You don't need a super expensive 80+ platinum psu to run a modern gaming rig. If you were to do extreme overclocking then of course you'll use the best hardware money can buy but this doesn't apply to everyone..

I'm not saying a 780ti with the cx600 is an ideal match but its not as disastrous as you seem to be implying.

Just seen this thread, I run a very similar system - 2500k at 4.6ghz. Gigabyte 780 ti oc at standard clocks.

Last weekend I ran using afterburner on CPU and GPU, full clocks for an hour, and recorded a consistent Power requirement of 559w (I have a digital UPS with readout).

600w as a power supply will therefore be pushed. as discussed here and in other threads, 600 is often peak output, and depends also on rails.

for ref I run on an 850w with no issues.

Ok mate if you say so, love how you just cant educate some people, CX is budget, generic psu come with pci-e cables too, and if thats how you pick your PSU based on cables then good luck to you, il base my mine on 25 years experience in this game, educated people that buy a 780ti along with there Z boards and i5 and i7 dont buy budget PSU, and it obviously is as disastrous as i imply otherwise this thread would not exist, there are better lower watt psu out there that would out perform the CX range including psu from the same brand, they are not all equal despite what the numbers on the box say

if you require 600 watts of power you should not buy a 600watt PSU you should always buy more than you need, and same with the amps, something a lot dont even consider and take for granted

A year old budget psu would like the CX range would struggle to sustain that output for a period of time, where as a quality midrange psu like the 620W Seasonic S12II would handle this much better, at th end of the day you get what you pay for, DONT SKIMP ON THE PSU
