Can my PSU power this monster graphics card?

kir13y · Oct 23, 2015

I am thinking of getting a Nvidia EVGA 980 TI graphics card. I currently have a 875W PSU (I think and I will check tomorrow and update). I currently have a 750 TI FTW from EVGA and a GTX 480. I have a triple monitor setup and I am currently running the big middle monitor on the 750 and the other two side monitors are on the 480.

So, can I run the 750 and the 980 with my current PSU?
Thanks internet users!!!!

The 980 TI only requires a 600w PSU if it's a capable power supply. So yes, the capacity of your current PSU is more than enough. Whether the quality and reliability are sufficient is a different story though. Some units are barely able to provide a portion of their rated capacity, and tend to die quickly under strenuous gaming loads. Even a lot of those sold under well known brand names are junk in reality. The model and internal platform is the key.

What is the model and brand of your 875w PSU?

Yes it can

Vighnesh Misal :

So you're saying if he has an 850w Logisys or Raidmax power supply, you'd recommend it for use with that card? C'mon man. Find out what kind of hardware you're dealing with before instinctively saying yes. Just because a unit says it has 850w doesn't mean it can even provide 450w continuously without exploding, catching fire or just taking out hardware when it dies.

We need the make and model of the psu to make an informed answer.

Darkbreeze · Oct 23, 2015

^^^Exactly.

Vighnesh Misal · Oct 23, 2015

Darkbreeze :

You're absolutely right. I simply assumed he would have one of the popular brands like Antec, Corsair, Seasonic or Cooler Master. But that's no excuse for the sloppiness.

I found an Alienware Aurora R4 for very cheap and I am almost certain that this is the current PSU that is in it: http://www.amazon.com/Genuine-Dell-Precision-Workstation-Compatible/dp/B00BTMT8YC

Darkbreeze · Oct 26, 2015

Yeah, I'd NEVER use that, or any other OEM PSU, with a high end discreet card. For a GTX 750 or R7 240, or lower tiered cards, it's probably ok, but not for high end gaming cards. You absolutely want a Tier 1 or Tier 2 unit for use with any high end card.

However, I think maybe that Alienware unit may use a proprietary DELL PSU design, which may not be compatible with standard ATX power supplies. You may be able to find the information needed at the following link. I'll look into it further if I get a chance after while.

That link could be 1 of 3 units, and 2 of the the 3 are not good. The UL number on the W299G has a UL number that points to Delta as the OEM, and Delta is normally a good PSU OEM. However the J556T and U595G are made by Chicony(according to the UL number) and they are not a good OEM. Look at the side of your PSU to confirm the part number. If you have the Delta unit it may work, but with a $650+ video card I'd err on the side of caution and buy a PSU thats known to be good quality and adequate for the system. A good PSU would cost about a 10th of what a the 980ti costs.

Darkbreeze · Oct 27, 2015

Also, knowing the part number would certainly allow us to be able to determine it's dimensions and form factor. You might also get the exact part number of the PC unit as a whole, because like I said before, some of those units use a proprietary case and PSU. If yours is such a unit, then a standard ATX PSU is not going to fit in all probability. And depending on what motherboard is installed, if it too is a Dell proprietary motherboard it may not even use a standard 20 or 24 pin power connector.

One more consideration is that in PC's like this, there are space constraints and airflow constraints. A 980Ti will need good airflow to cool it.

Here are some pictures of the current pc:http://imgur.com/a/GmHnx
Sorry for the blurry 3rd image. I will take a new picture tomorrow.

Darkbreeze · Oct 28, 2015

Yeah, that doesn't help. Pictures of the unit's identification label with the model and serial, the power supply label and the connections from the power supply that connect to the motherboard would be helpful, but still may not answer all the questions. These Dell (Alienware) units were never intended to be upgraded. They are intended to be permanent and throw away solutions. Some compatibility on particular models exists, for aftermarket parts, but some models are extremely limited when it comes to form factor considerations and proprietary hardware.

Simran Jeet · Oct 28, 2015

yes ur psu can handle these two, even ur psu can handle two 980ti too

Simran Jeet :

Guess you didn't bother to read the rest of the thread. Maybe you should do so next time. It's funny that you're asking for advice on a PSU in another thread, and trying to offer advice about a PSU in this one. This particular power supply is unlikely to be of any reliable quality unless it happens to be the Delta model, which as of yet we do not know.

So I actually have a pretty new 750W corsair modular PSU. It looks like it will fit but I don't know about the case light boards on the side of the current PSU. Any ideas?

Until I know the exact model number of the PC unit and the exact model number of the PSU, I can't help. Sorry. Pictures don't really tell us much especially when they're not pictures of the questionable areas as were asked about before.

kir13y · Nov 4, 2015

Ok. I will get the model numbers to you asap so that you can check it out. Thanks for all of your help so far!

Darkbreeze · Nov 4, 2015

Sounds good.

kir13y · Nov 4, 2015

So, I think the PSU model number is: DP/N 01N03G. It is made by DELL and came installed in my Alienwear Aurora R4. I found this fourm with another guy who has the same PSU and they said that if it has a button on the back then it is the 875W model. Mine has the button on the back so I can confirm that I do have an 875W PSU.

I figured out that my Motherboard model number is: 07jnh0 [Manufacturer: Alienware]

Hope this helps!

Darkbreeze · Nov 4, 2015

How many 6, 6+2 or 8 pin PCI power connectors does that power supply have, if any? What are the dimensions of the power supply as I can't seem to find ANY specs on that PSU model. Your motherboard seems to use standard 8 pin and 24pin motherboard power connectors, so that part should be fine IF you end up having to get another power supply.

If your current PSU has the necessary PCI connections for the graphics card then it might be ok to try and use it since it's over spec, but honestly, I wouldn't trust an Alienware or Dell PSU unless it was a Delta model, with my expensive graphics card, any more than I'd trust a Raidmax or Logisys unit. It's probably not as bad as those kinds of units, but I doubt it's anything to write home about either.

kir13y :

01N03G is the part number for the case not the PSU. You will need to pull the psu out as the sticker with the part number and specs is on the other side of the unit.

Alright. I will take it out this weekend and post the PSU part number this weekend if I have time.

Can my PSU power this monster graphics card?
