Question GTX 1070 + VS650

[Yash RG]

I am building a new pc with i5 9600k + gtx 1070 (2nd hand) and I have my old psu VS650 which has 2x(6+2)pin pcie connectors but both are in single cable. previously I had a gtx 670 and it required 2x6pin pcie so I powered it with 1x6pin+1x6pin(from 2molex to 1x6pin). so my question is can I use the same psu to Power any gtx 1070 variant? is there any 1070 variant which uses a 2x8pin pcie and if there is can I use 2x8pin from my psu which are in single cable?

You can use daisy-chained 6+2pin connectors, that's why they exist? While it might not be perfect, it's certainly preferred vs molex adapters!

However, the VS650 isn't a great PSU. I'd be cautious using it to run a 1070. I would suggest a better quality PSU, but don't focus too much on the daisy-chained nature of the PCIE connectors.

You're fine. 650watts is plenty for a 1070 no problem.

why is vs650 not a good psu? bcoz of it's low efficiency?

it's enough I know, but is vs650 good enough for a gtx 1070?

Nothing to do with efficiency, no. It's a budget unit, built down to a pricepoint. The main problem with those units are the cheap(er) capacitors used, and the unit will typically last through it's warranty period (3 years IIRC) and not a lot more.
That assumes it's not stressed too-too hard. On a low powered system, it may well last a lot longer. On a heavy power draw system it might not see 3 years. Certainly after 3-4 years, I wouldn't feel too great about it.

I assume you've been using this VS650 for a few years at this point?


While it's not a great unit, it depends on regional availability. The VS lineup, unfortunately, can sometimes be the best of a bad bunch available in certain regions.

VS650 suitable with the GTX1070(not the best psu but also not the worse. Its enough for GTX1070).

Not the worst, no.

But, equally, it could feasibly be ~5 years old. The older VS650 units first came to market around 2013 IIRC. The GTX670 the OP had previously launched in 2012, not too unrealistic to think this is a ~5 year old, budget, fairly low quality PSU.
It could certainly be worse, not disputing that - but I think we're a ways away from being able to say with absolute certainty that it's "enough" without issues.

Either way, it's not likely to be a fire hazard, but I wouldn't be confident stating it'll work without issue.

To be 100% clear here OP, do you have the original VS650 :

Or the 2017 revamp:

Neither are great, and judging from your description of "old", I'm thinking Orange VS.... but if it's the newer/revamped lineup, it should be fine for a while yet. Not great, but adequate.

I have the orange vs650 model
so if I have to buy a new budgeted psu which should I go for?

 

[Barty1884]

Where are you located @Yash RG ? And what kind of budget would you have?

5500 rupees, approx?

Corsair's CX550 is a solid unit.

not seeing a whole lot online otherwise.

Perhaps locally you coudl find a SeaSonic S12II or M12II? They're older platforms, but still quality. Online though, they're going for about 7000 rupees.

I can do tx650m 8000rupees, is it good enough for a gtx 1070 or for a future upgrade to 1080ti with max overclock?

 

[Barty1884]

The TX is a quality unit, yes. Should be plenty capable for a 1080TI overclocked too!.

just can across a smps Antec Earthwatt its a 80+ gold rated 700bucks lesser than tmx650 and comes with a 7yr warranty. Do you know about this smps?

 

[Barty1884]

Do you have a specific model number?

If it's the EA750G Pro or EA650G Pro, those are SeaSonic OEM units and great quality.
If it's anything else in the Earthwatts lineup (I think the rest of their Gold units are FSP made), I'd probably still opt for the TX650M.

it's cheaper than TX650M, I mean cheaper than antec 650w

 

[Barty1884]

Quality, SeaSonic made unit. If it's cheaper, it's a great choice.
