r9 290x psu help

[amd1361]

I have just bought an Asus r9 290x direct cu II.
HERE IS MY RIG
CPU :core i7 6700
MB :asus z170a
Ram :16gb 4*4 trident z 3200
Power supply: corsair 650 watt
On the box of the graphics card the minimum psu recommendation is 750 watt (i noticed that after buying it)
my question is that
Is it safe to use the card with the above mentioned power supply?
Do I have to change it with a better one?
if i use the card, does it reduce the lifespan of my system? (if it is so which components are in danger)
thanks

you should draw around 590W.
if it's a good Corsair series, you'll be fine.
however if it's one of Corsair's low quality PSU I advise caution.

thanks for your reply
what is a good and a bad corsair?
I mean how can I recognize if my corsair psu is good or not
thx

you look on the PSU which model you got.
there's usually a fat print on it saying CS/CX/RM/whatever
depending on the series, the PSU is good or bad.
if there is CX650M in green letters, I'd be cautious, if it's written in grey letters you're fine. (the CXM is the most common series by Corsair)

Tptal system power draw "at the wall" = 400 watts

An that's with an Intel Core i7-3960

Card draw was about 287 watts for the card

Here is Guru3D's power supply recommendation:

AMD R9-290X - On your average system the card requires you to have a 550~600 Watt power supply unit.
AMD R9-290X Crossfire - On your average system the cards require you to have a 800 Watt power supply unit as minimum.

If you are going to overclock GPU or processor, then we do recommend you purchase something with some more stamina.

No way to tell the quality of the PSU w/o a model number

Anything with a "C" in it = bad
RM - Not Good
RMX - good
HX / AX - Great
TX V2 - Good

it's pretty bad 🙁
the VS series is a low tier PSU and not recommended.

where are you from?
where do you usually buy?
maybe we can find something nice for you...

Seems like it is the Corsair VS650. VS series is the lowest quality from corsair.

I would not recommend putting your R9 290x gpu with that power supply. But it should work temporarily. Buy a descent unit asap.

 

[amd1361]

my last question is that can i just test the graphics card with the current psu by putting some stress and running some games before buying a new one
cause i want to make sure if it is ok and i have been given just 24 hours to check it

The Corsair VS is made by CWT on their GPM platform. That's the same ame OEM that makes their RMI, TMX, HX series

The GPM platform is also found on the Thermaltake TR2 Challenger and Thermaltake Smart SE . The initial model VS650 (75-001837 / CP-9020051) has since been discontinued the later VS650 (75-001837 / CP-9020098) I believe was solely for Euro distribution.

It is Corsair's budget line, comparable to the CX series. I am not in a position to judge the sepcific model size as no reputable english site has reviewed either... I did find a review of the Thermaltake Smart SE on a Russian site and was able to translate a few european reviews on the VS 450 which were not very flattering... here's one that is readable, main complaint being CapXon capacitors, voltage stability and potential long term stability.

Unfortunately, and this is the problem with tier lists, just because the 450 fared poorly, this doesn't mean the 650 suffers from the same shortcomings.

If you just bought it, you might think about exchanging it for something better. If it's something you have used fro a long time, then I'd think about replacing it, if you conform that it indeed has those CapXon caps. If it is relatively new, and you have no option to exchange, it will certainly be serviceable but, I certainly wouldn't get into a 2nd card in crossfire or even heavy overclocking.

so what should i do now can i just test the graphics card with the current psu by putting some stress and running some games before buying a new psu
cause i want to make sure if it is ok and i have been given just 24 hours to check it

1. Please read my previous message

2. This test will prove what ?

a) You can run a test like OCCT PSU test which, they warn, may toast a cheap PSU

b) It will not blow up in which case ?

The problem with those PSUs is that the capacitors degrade over time and the PSUs viability in the long term is questionable. The PSU is fine for light duty for a typical PC build... where it fails is in heavy sustained usage o9ver a period of time.
