Do I need to upgrade my PSU?

[Ivan Soria]

I currently am Running this:

Corsair Enthusiast Series TX750M Modular Power Supply - 750W, 80 Plus Bronze, Single +12V Rail

Intel Core i5-3570K 3.40 GHz LGA1155 CPU

ASUS SABERTOOTH Intel Z77 Chipset LGA

xxx -Corsair High Perform Vengeance 16GB DDR3 1600Mhz4x4

Lite-On IHDS118-04 Internal DVD Drive - DVD-ROM 18x, CD-ROM 48x, SATA (OEM)

xxx- EVGA 02G-P4-2670-KR GeForce GTX 670 2GB Video Card - 2GB, GDDR5, PCI-Express 3.0, DVI-D, DVI-I, HDMI, Display Port, DirectX 11

OCZ PTL1-25SAT3-128G Petrol Solid State Drive - 128GB, SATA III, 2.5"

WD Black 1 TB Desktop Hard Drive, Designed for High-Performance - 3.5" - Sata 6 Gb/s, 7200RPM, 64MB Cache, 5yr Warranty - WD1002FAEX


I will replace the xxx with these parts:

ADATA USA XPG V2 Series 8GB DDR3 2400 PC3 19200 (4GBx2) Kit AX3U2400W4G11-DMV

2 of EVGA GTX 980 SC ACX 2.0 4GB GDDR5 Graphics Card(SLI)


Note: Am I missing anything crucial that will impact the PSU draw that I should include like my monitors?

Your PSU meets requirements for 980 SLI.

Your current PSU should be ok, but where its an older unit if you want to do any overclocking you may want a newer/bigger PSU. I see no need in the ram upgrade you are not going to see much if any difference unless your current ram has cas of 11 or higher. Monitors do not draw their power from the PSU, they have their own power cords.

I think it should suffice, but you'll need a bit of headroom for some OC(850/900W, if you plan on any), but it should suffice!
I'm not too experienced in PSU's but sounds like it should work, they(GTX 900 series) are very efficient.

The RAM upgrade was because 3 out of the 4 sticks I had ended up breaking due to mishandling (on my part).

I believe the cards I bought come OC? I may be wrong.

Here is the link where I bought them:

If they are, 900w should be good?

More than enough, they state 500W for one GPU, lets say max 200W for the second one in SLI, you'll be fine with those two on a 750W PSU.

But as bignastyid mentioned, it's a bit older PSU.

Why is it a bad thing that it is an older model PSU?

 

[VedranMik]

With time the internal components of a PSU degrade as it gets older which means it becomes less efficient, produces more heat, has less stable output voltages.
How exactly old is your PSU?

I bought it in 2012

Superclocked versions of GTX 980 can use up to approximately 275 watts at maximum stress. With 2 cards running near maximum and the rest of your system included, you could approach about 650+ watts usage, total system maximum load. While your PSU meets stated requirements for reference clock speeds, actual loads you may encounter with superclocked 980 versions, indicate an upgrade could be warranted. 850-1000 watts from a high quality PSU would insure you have no power related problems.

Thanks man, I'll go ahead and upgrade then.

Better safe than sorry.
