Hell,

I have just ordered a AMD raedon 270x Graphics Card. Now I noticed it requires two 6 pin connector but Coolermaster 450w has just one 6 pin connector. So would it be safe to use two 4 pin molex to 6 pin connector to use with above graphics card. I have very linear setup -
CPU - Amd phenom 2 560
RAM - 4x2 = 8 gb ram
HDD - 1 tb Segate

Just above hardware.
So please regarding above issue.
Thanks!

Yeah, you get those connectors with graphics card too for compatibility purpose.

Just check that your PSU is able to deliver the total wattage for your system.

I wouldn't call that exactly safe. I would call it trying to save money

How much is AMD raedon 270x Graphics Card when you ordered it?

If it comes for 13.5k then you can go with MSI GTX950 OC which has one six pin PCI Express power connector so no issues with your power supply. Just think over it.OK.

Even GTX 960 came down to under 10k recently ;)

It came down for one particular deal, chances of that happening again is next to none

The min price of GTX 960 is still around 15k

I got my 270x for just 10k in a deal. AlsoI have this coolermaster 450w PSU which i thought is powerful enough to power this 270x. But its just short of a connector.

- - - Updated - - -

950oc is available minimum for 15k online. Not available ij my locality.

I wonder if CPU will be a bottleneck

PSU is borderline risky as 500W is recommended, could have gone for lower power Nvidias or R7 265/370

I bought because of a deal. Also as for PSU I have bare essential hardware, nothing extra. So will it be enough?

Its better to change your PSU to Antec VP550P @ 4.4k

Im on a very very strict budget. So as of now I will have to settle with my current PSU. I checked power requirement of 270x on various websites and according to them it can draw most 275w and my other hardware is bare minimum essential only. So I guess I can carry on my current psu.

The wattage is not the problem. It's the quality of the PSU that's the problem.

I thought Coolemaster is a well known reputated brand. Even Digit magazines recommended configuration for Basic Gaming PC recommend above PSU.

Cooler Masters PSUs are crap. Better buy Antec if low on budget.

If that PSU is crap than I'm wondering how come it is recommended by digit magazines for Gaming PC rig.

Which model is it exactly? Antec and Seasonic provide better PSUs at the same price

Say the exact model of your PSU. CoolerMaster has some good PSUs, but also had some bad ones.

MOLEX to 6-pin PCI-e if fine to run.

For the record, I'm running a HD 6950 on a Corsair CX430v2 with a MOLEX to 6-pin PCI-e converter. Just don't push the limits by overclocking or mining 24x7.

Digit probably put it under basic gaming rig with a lower end GPU, check the PSU for the rig with 270x or equivalent .

I'm guessing, Is it Thunder series?

Here is a review of a Thunder unit

We must criticize the low material thickness, especially as we have found when you open that many corners are quite sharp.A thin body is not only cheaper, but also affects the shielding effectiveness.Radiated interference can thus act more outwardly.

At the low-pass filter at the output, among other things, the capacitors WL from Jun Fu and KF of CapXon be used.

Since the model reached partly less than 80% efficiency even at 230 V, it logically deserves no 80 PLUS award.

Jun Fu caps are of sh*t quality. Any PC having mid-range to high-end GPUs should ideally be using Tier 1 caps from this list.

But there are positive reviews also -*www.hardwaresecrets.com/cooler-master-gx-450-w-power-supply-review
Also one which i have is 85 efficiency PSU.

GX is a different series! (also not great btw). Ok you thought that the link I posted is of a different 'B' series. Nope. It's the same Thunder series. It's sold in China under the 'B' series name. Low cost PSUs usually have jhol naming schemes. A review from one country should not affect the market of another country.

I bought above psu just recently. So now I cant buy a new one. So how long do you expect can I use it safely after which it will impact other Hardware or itself ??

IDK. If you had asked for advice on any decent forum before purchasing the PSU everyone would have told you not to purchase that CM PSU. In fact any CM PSU. The PSU certainly is prone to problems:
Oh! No. Not again. PSU is busted - AnandTech Forums

All lower end CM PSU's are just crap. If you really want to buy CM PSU then you need to buy 10k PSU range otherwise Seasonic M12II 520w @ 5.9k is best in regards to price to performance ratio.

Return it then. The shop should have a return/refund policy.

Should ask the shopkeeper to get you Antec/Seasonic PSU in exchange of CM one. Or you can ask him to replace your components with new ones in future for free if they get damaged due to the PSU.

Still one thing though. If that PSU is so much crap than even digit crew isn't aware of that ??? Even in the latest issue they have recommended it for Entry Level Gaming PC with a R7 265 Graphics card? ???

For entry level gaming now-a-days, 750Ti is bare minimum. Along with Antec VP450P.

Read that article guys about the Coolermaster PSU.

I think its not that bad after all.

Ign India recommending above psu for higher gaming pc and also even digit guys recommend it for basic gaming pcs.

lol don't trust them especially Indian reviewers. They just stress test the system once for 30 minutes or so, use it maybe 4 hrs a day under light load. They don't use it for more than 8 hrs a day under load. After 2 or 3 years of usage it will definitely die and during its course it will also damage your other PC components if its voltage regulation is bad.

The PCIE 6-pin is rated for 72W @12V = 6.24A. This is spread across 3 power lines for 2.08A each. With only 2 of the 3 12V connectors attached even at only 60W those leads are pulling 2.5A a piece

If you want to see the glass half full ... had the Molex side of connector not burnt likely it could have destroyed your graphics card. Honestly whoever made that connector should be sued and if it was included with a GPU whoever included it should be sued too.

Standards exist for a reason.

Hmmm . interesting theory. But I've ran 9600GT for like 6 years with such an connector and the GPU is still fine though I don't use it anymore now.
