PSU for Workstation

[Princess Luna]

Greetings! My brother is upgrading his personal/workstation computer a lot of the software he uses allows CUDA Acceleration with multi-GPU and he has come across a very good second hand deal on our local eBay for a second graphics card, his previous power supply had a bit of coil whine so replacing it was happening either ways.

 

I believe that 850w should be enough for the system however I also take insights about it since as far as I am concerned 7200rpm hard drives consumes a fair share as well, the system is as follows:

CPU: Ryzen 7 1800x

MOBO: Asus PRIME X370-PRO

RAM: 32GB Corsair Vengeance LPX

GPU: 2way SLI nVidia TITAN X Pascal (2016 model)

Boot: 480GB SanDisk G26

Storage: 4x 2TB Seagate Barracuda

 

Now before every one comes here throwing random power supplies names I have already made the best I could research wise on our Brazilian local market and I would just like discussing a bit before picking something, the deal on the second TITAN X Pascal was very good but it still is an expensive card regardless so budget is tight and saving is appreciated.

 

Cheaper alternatives (so the most desirable obviously):

Riotoro Enigma 850w 80 Plus Gold

Corsair TX850M 80 Plus Gold

 

Medium priced alternatives:

EVGA G3 850w 80 Plus Gold

Corsair RM850x 80 Plus Gold

 

Most expensive alternative:

Seasonic X850 80plus Gold

 

Thread open for debate ^^

@Princess Cadence what's the current wattage of his PSU?

[cj09beira]

you will be fine with any of them

Use a PSU calculator to check if the Wattage is sufficient or overkill, but i don't know which of those products is the best out there (the Gold rating is good though)

No longer an alternative as it has already been sold.

Fairly aware of wattage calculators out there, been looking more for personal experience out there though.

Is the wattage similar to what his old PSU was? as if this is like drastically more power than he need you could be forking out money for watts that won't ever get used.

I've only owned one PSU so i don't know what's best, sorry

[Xander Cousins]

@Princess Cadence In all fairness I would go for the Corsair RM850x as I have hear some good things about the PSU

I use the Corsair RM850x 80 Plus Gold in my office PC. It's got a 4930K, 2x GTX 1080s, 2x SSDs, 6x 7200 RPM HDDs. Has been a solid performer for years. Not sure how much more the Titans draw then the 1080, but it should be close enough overall for comparison.

 

Edit: Used had instead of has accidentally. It is currently installed and functional.

Always pleasant hearing feedback on good experience with one of the products, the TITAN X Pascal draws pretty much identically to the FE 1080 Ti, 850w seems like the right amount, won't lie we're leaning towards either of the 2 cheaper alternatives but given how down times could cost my brother we can not give ourselves the luxury of ending up with a faulty equipment... main reason why I was hoping the more experienced users could give their thoughts, cheers!

Since you asked for personal experience. I've used Both the Corsair TX and RM series and while both are nice I prefer the RM. The RM fan only turns on when the cooling is needed and there is at least to me a slightly more premium feel.

 

I just installed my first EVGA G3 unit a few days ago and I really like to so far ( super premium feel and full modular) but again I just installed it.

I'd go for the EVGA G3 850W unit, however, the 2017 Corsair TXM is also a Tier 1 PSU with 7 years of warranty so it's a good pick as well

[hconverse02]

I think you should get the corsair rmx 850w, because of its reliability and because it's also fully modular.  Alternatively, the g3 is good quality and won't fail him.

I'd go with this mainly because this is the one I have  Plus it has a 10 year warranty. The full modularity is a great option. Like what was said earlier, it follows a fan curve that it sometimes turn off when the power draw is very low, which limits the noise.

The RMx should be the quietest out of those, and it has a fairly long warranty. So that would be my pick. 

[Damascus]

TXM is nice, though I might consider getting a 1000w psu in your shoes.  Crossfire r9 290 + 290x, one 7200rpm hdd and an i7 860 had me at the limits of my AX860.

Well for what is worth power efficiency has severely improved since... We are leaning now towards trying to afford the RM850x as it has been a good "seller" in here so far... will hold up to what @STRMfrmXMN and @jonnyGURU has to say on the better before marking solved though

For two Titan X's and an 1800X I'd personally put a 1000W in my system, but that's just me. If you don't OC anything then a 750W PSU should be fine.

He does run all at stock reason why the 1800x over the 1700, as stated previously down times will be troublesome so better not mess with OC'ing at all if we can avoid it, only memory was overclocked in the system to 2933mhz.

 

The step up to 1000w would mean increase in pricing that can't be met right now without resorting to credit which would be nice to avoid...these PSUs are also even harder to find and fairly more expensive thereafter if they can be avoided all the better... our tech market has its deficiencies.

If the RMx 750W/850W is in your budget then go for it.

 

That said, you cannot seriously be going into debt for a dual Titan system lmao

Both cards were purchase on second hand deals after the 1080 Ti release what rendered them a bit pointless so there's that hehe... the RM850x it is we placed the order.
