Is it good enough to run a card like GTX 970 / R9 380x?

Eximo · May 20, 2016

Just about 900W, plenty to run either card.

12V1 @ 300W (25Amps)
12V2 @ 300W (25Amps)
12V3 @ 336W (28Amps)

[strike]looks like it is a 300W power supply. the best you could safely run on three is a GT 740. a 750ti could be a stretch. for those cards you mention you would want a decent 550 watt power supply by EVGA, XFX, Seasonic, Super Flower, or Corsair (but not the VS or CX/CXM series) and at least 80 PLUS BRONZE. the 970 could get by on a decent 500W.
[/strike]
300 per rail... never mind. looks like it could be an alienware OEM PSU or something. if that is the case it is 100% fine, if it is some cheap brand then no.

Uhh it's an old design PSU and shouldn't be used I guess, can't be sure though. 3 12v rails provide the needed 936 watts.... And I guess it's a 1200w PSU.....

But what is more important is its brand and quality and model. You want a high quality PSU to safely provide clean power to the card.

So what brand/model is it?

Eximo · May 20, 2016

I think the logo might be HI-TECH, can't really tell. Google is being overrun with power supplies that have a similar model name.

Not a 1200W supply if they only rated the total output at 900W, that means it can dissipate its heat while delivering 900W output at some rated ambient temperature.

Warthis · May 20, 2016

It says ATX - P4-900w and on the side there's the word "PROTECH" is that a good brand or..?

Thanks in advance!

Robert Cook · May 20, 2016

I cannot find anything on it. Protech could be a protek ripoff? Nothing relevant to power supplies came up on google. I do not trust it.

Eximo · May 20, 2016

It is quite a bit more capacity then you need. I would just give it a try.

Even if they weren't 100% truthful with the specs and the 900W rating is at 20C or something silly, it is probably a decent 600-700W continuous output supply which is still enough.

Robert Cook · May 20, 2016

Eximo :

I don't know, the fact that there is nothing on it worries me. Also if they lied on one thing who is to say the power coming out is stable or even clean? I am still looking for more info, but it seems there is none. this thing should work, but it is a crapshoot.

Warthis · May 20, 2016

let's say I want to be in the safe zone and have the same power supply and not buy another one, which GPU I should go with? GTX 970 or R9 380x?

mjslakeridge · May 20, 2016

I couldn't find anything on it either, looked on Tom's PSU Tier list and Google. Where did you get the PSU? How old is it? Currently in use?

Robert Cook · May 20, 2016

yes, as mjslakeridge says, is it already in use? and what was it powering if so?

Warthis · May 20, 2016

The PSU is running the PC that I am on at the moment, I bought the PC like I don't know maybe a year ago or more
I checked on command prompt when the windows was installed and it pointed out 16/1/2015. so I don't know when I
exactly bought it, I think it would be around 1 year or something.

my PC build has i5 4690 and a 1TB storage, 8GB of RAM and a H91M Plus or something as motherboard and this PSU as graphics card I use the integrated graphics card that comes with the CPU Intel Graphics 4600.

mjslakeridge · May 20, 2016

If you bought the computer as a pre-built, then most likely, the company used a very low quality PSU to improve their profit margin.

I don't think a day goes by here on Tom's that we don't see a low quality PSU fail and we are left trying to figure out whether it killed the motherboard, CPU, GPU, all of the above, none of the above, etc.

The low quality models use thin gauge wiring, poor Chinese-made capacitors and don't have good fault protection circuits (to prevent damage to computer components when it dies).

madmatt30 · May 20, 2016

If its anything like resembling a quality unit (that model number on it I would assume puts it as a 900w PSU) then it will 100% have 4x 8 pin pci-express power connectors.

Warthis · May 20, 2016

I assume someone built it I mean like it's not for some company I think so what do you think and what do you mean by "4x 8 pin pci-express power connectors" is that good or bad?

mjslakeridge · May 20, 2016

Can you post a better picture of it (more light). I can't read the "Made By "

Warthis · May 20, 2016

Here you go:

Does this brand run a GTX 970 / R9 380x?

madmatt30 · May 20, 2016

King yes international would be a 100% outright no from me personally.

Check you PSU cables , this is a pci-express connector

A PSU with 12v rails of that size should have 2 pairs of those- I would be doubtful if it even has any 8 pin (6+2) connectors at all.

mjslakeridge · May 20, 2016

Thanks for the better photo. I couldn't find anything out about King Yes International Co. Ltd. as far as PSUs. Looks like they manufacture all kinds of things.

As Madmatt said, I would avoid using it.

Warthis · May 20, 2016

Are you talking about something like this:

mjslakeridge · May 20, 2016

I think what Madmatt is saying (he can correct me if I am wrong), is that if your PSU is a good quality unit, it will have two 8 (6+2) connectors and two 6 pin connectors.

I believe the R9 380x requires two 6 pin connectors for power. Not sure about the GTX 970, I couldn't find any pictures showing the power connectors on that one. Probably someone here owns a 970 and can say for sure.

Edit: And yes, your photo is showing a 8 pin (6+2) connector.

Eximo · May 20, 2016

Reference 970 take two six pin, some aftermarket take an 8-pin and a 6-pin.

madmatt30 · May 20, 2016

Warthis :

youll have to spin that cable round,its the wrong angle to tell.
irregardless with both a 380 & the 970 (power requirements are pretty much identical on both) you 100% need the cable configuration I put in the picture above as a minimum - meaning 1x 6 pin & 1 x 6+2 pin powr connectors.

None of us have any idea whatsoever what kind of quality that unit is - the 12v rail specs on the label make it seem as if it would power just about any setup but in all honesty ( not meaning to sound at all rascist) when I see a made in china badge & no real sign of actual manufacturer branding it really does not fill me with confidence

Eximo · May 20, 2016

They are all pretty much made in China, in the same district even. Up to the company employing them to ensure quality.

How much wattages do I get from this power supply?
