What is this Red switch for on my PSU? RAIDMAX RX-730SS

Ferrariassassin · Jul 7, 2014

Here is a link to the exact PSU i own and i do not mean the red button as it turns on the Blue LED. It did not come with instructions so i do not know.

The red switch with 110 printed on it is the voltage selector.

However...if you're using a RAIDMAX PSU....do you have a fire extinguisher handy?

Lol funny. some of my friends had the same one i got and it never broke. I mean if i bought a 730W PSU of any other brand i would be paying in the thousands range

And some of my friends went street racing and didn't die. Some of them.

USAFRet :

Well i just got it in the mail today, i can easily send it back saying it is broke or something. I just cant find any other PSU under $500 that puts out atleast 700W

Ferrariassassin :

RAIDMAX PSU's are in the category of "Replace Immediately".
Will it die tomorrow? Probably not.
Is it far more likely to die than a better class of PSU? Yes.

And when a PSU dies, it can easily kill off other components in the system. In the extreme case, a dying PSU can start a fire.

Your call.

i felt a shiver go up my spine when I read raidmax. Quality PSU's are a must these days its the only way to truly protect your investment (the rest of the parts). I'm a fan of anyone that gets their psu's made by seasonic but rebrands them I know corsair does for example and I think the newegg in house brand Rosewill does as well. I've had my 750W rosewill platinum for 2 years now..no issues.

also just basing my initial thoughts, that psu has a ton of 1-star reviews totaling 16% of the overall reviews..that's enough to make me move on right away. Hell just read the customer support rep's broken English on all of the negative replies...no thank you!

Ok thanks. Here is my setup
CPU-i5-4590
GPU-MSI R9 270 GAMING 2GB 256-Bit
MB-ASRock H97M Pro4 LGA 1150
Memory-2X4GB RAM
HDD-WD 1TB
DVD-One Asus DVD Drive
OS-Windows 8.1

So do you think i even needed 730W in the first place? And i wonder if Newegg will give me a refund lol.

For a system using a single Radeon R9 270 graphics card AMD specifies a minimum of a 500 Watt or greater system power supply. The power supply should also have a maximum combined +12 Volt continuous current rating of 30 Amps or greater and have at least one 6-pin PCI Express supplementary power connector.

Total Power Supply Wattage is NOT the crucial factor in power supply selection!!! Sufficient Total Combined Continuous Power/Current Available on the +12V Rail(s) is the most critical factor.

The instructions should say send me back.

So how do i know the total of a PSU?

It does not matter. Do not use it.

Dark Lord of Tech · Jul 7, 2014

No a solid 550w can easily run that.

Ferrariassassin · Jul 7, 2014

USAFRet :

Lol, im not man i mean like how do i know the total of any PSU i would buy. How is this one? Does it support Haswell because i have a i5-4590

How is this one? Does it need to support Haswell because i have a i5-4590

Haswell ready.

It should be specified on the PSU's label.

Ferrariassassin · Jul 7, 2014

Thanks and i wonder why they make haswell ready PSU? I mean all a PSU does is give power to everything so why does it matter if the PSU is H ready anyway and how would my CPU even know?

Ferrariassassin :

The Haswell processors can enter a sleep state, called C7, that can drop the processor's power usage to as low as 0.05 Amps. Even if the sleeping CPU is the only load on the +12V rail, most power supplies can handle a load this low. The potential problem arises when there is still a substantial load on the power supply's minor rails (i.e. the +3.3V and +5V rails). If the load on these minor rails are above a certain threshold (which varies by PSU), the +12V rail's voltage may go out of spec (i.e. voltage greater than +12.6V). If the +12V rail is out of spec when the motherboard comes out of the sleep state, one or more of the PSU's protection circuits may be triggered preventing the PSU from running and will cause the power supply to "latch off". This will require the user to cycle the power on their power supply using the power switch on the back of the PSU.

hmm thanks man, i am ordering this one do you thin it will work goot with the i5-4590 and the ASRock H97M Pro4 LGA 1150 motherboard? And thanks man i really appreciate it, here is the PSU ii found what do you think?

Ferrariassassin :

The Corsair CX600M isn't Intel Haswell ready. You would have to ensure that C6/C7 power state support is disabled in the motherboard's BIOS setup if you're going to be using that PSU. The only Corsair CX Series models that are confirmed Intel Haswell ready are the CX750 and CX750M because they are based on a newer platform than the lower wattage CX models that are based on an older circuit design.

vagrancyx · Jul 7, 2014

Yeah i dunno why you thought you needed a 730 Watt PSU in the first place. Hell I don't even need my 750, I just bought it because it was a great price at the time.

^ is a pretty nifty calculator, while it might not be 100% (Probably is pretty damn near close) accurate, its a good baseline.

Ferrariassassin · Jul 7, 2014

vagrancyx :

Dang i put all of my componets in and it says i need a 600W PSU

Dark Lord of Tech · Jul 7, 2014

THOSE thins aren't accurate they over estimate.
