R9 290X PSU question

CreepX · Dec 20, 2015

Hello , I found a refurbished Asus DirectCU II R9 290X 4gb for 300 euros ( A new Asus Strix R9 380X is 310 euros while an R9 390 is 380 euros ) , so my question is , would a Seasnoic S12II 520 W be enough to hold a R9 290X and an intel CPU (I5 most likely) ? Or should I go for a better one ?

yes will work, so long it is seasonice.

Thanks for the quick answer , the GPU is okay right ? I heard Asus R9 2XX cards weren't all that great .

620 watts or higher is recommended for the R9 290X graphics card. For your power supply the R9 380 is better.

And any R9 290 or R9 290X is very good.

Refurbished often shortens warranty and I personally would pay the extra money for the 390 which is overall better card and uses less power.

Hmm , Sirtec is a pretty popular brand in my country , there is a PSU , Sirtec High Power Element 700W , people are giving it great reviews , someone is able to run an FX 8320 and GTX 770 OC on it , so I guess the R9 290X shouldn't be a problem for it ?

Seasonic is good but 520w is too close for comfort with a 290x. The 290x is a power hog, it can use close to 300w on its own. I recommend atleast a quality 600w unit with a 290x.

I will see if I can afford a R9 390..

A friend of mine used to own a R9 290X and had a Corsair CX 600W , it ran without a problem . So I guess the CX should be good enough ?

bignastyid · Dec 20, 2015

CreepX :

Sirtec rate from mediocre to out right garbage quality wise and are best avoided.

bignastyid · Dec 20, 2015

CreepX :

It maybe running now but CXs have longevity issues due to poor quality capacitors and have a high failure rate. I don't imagine your friends system would have been running fine for much longer.

RCFProd · Dec 20, 2015

CreepX :

Corsair CX 600w uses weak capacitors, and with a GPU like the R9 290X it could fail on you even in as little as 6 months time. It is not a good power supply.

And Sirtec, also poor. I'm not sure who made High Power Element but if it is the Super Flower one It's ok.

koffeeshop77 · Dec 20, 2015

i still stand by my answer that the seasonic 520 is enough. that graph is under max presure setting and still only 291, the rest of his system wont eat up up the other 229 watts cause when on earth has your entire pc ever been fully maxed out all core and and all cept for occtional benchmark "spike" and even then with the he would still have some room to spare under normale condition. 520 sesonics is enough for a 77watt i5 and typical 250watt GPU

I can't seem to find a S12II 620W PSU anywhere atm , out of stock...

Any other PSUs in the price range of a Seasonic S12II 620W that will be enough for the R9 290X?

koffeeshop77 :

Well , if i won't be able to find a 620W S12II or a better PSU for the same price I will most likely go for the 520W one.

Sirtec is an actual PSU manufacture not just a rebrander/designer so i'd imagine they make their own units.

Haven't told us where you live so can't send a link. If It's US then it is in-stock everywhere:

Power Supply: SeaSonic S12II 620W 80+ Bronze Certified ATX Power Supply ($64.99 @ SuperBiiz)
Total: $64.99
Prices include shipping, taxes, and discounts when available
Generated by PCPartPicker 2015-12-20 15:32 EST-0500

Otherwise you have power supplies like:

Seasonic M12II 620w
XFX TS 650w
EVGA B2 750w
EVGA GS/G2 650w
Antec-HCG 620w
Rosewill Capstone 600+w.

Enough options.

RCFProd :

Never thought Antec and Rosewill would have good enough PSUs for such a GPU , thanks .

RCFProd · Dec 20, 2015

Antec = Rebranded Seasonic. I also own the Antec HCG-620w.

And the Capstone series from Rosewill are an exception to their series of bad power supplies.

koffeeshop77 · Dec 20, 2015

next on up wound be the 660 platinum series

CreepX · Dec 20, 2015

RCFProd :

XFX models aren't available in my country , neither are the Rosewill ones , I can't find the Antec one and all EVGA models are out of stock... so , Seasnoic is my only option I guess,

bignastyid · Dec 20, 2015

CreepX :

Many Antecs are built by Seasonic and Delta and are good quality units. Rosewill does have a couple good series like the Capstone, lightning and tachyon, but most of their other series are low quality and should be avoided. Here'a a link to the psu tier list you want a tier 1 or 2 unit of 600w or larger.

koffeeshop77 :

The platinum series is way too expensive ...

Then I honestly don't know what to suggest. You don't live in India?
